At a real estate​ agency, an agent sold a house for 343000​$. The commission rate is ​7.5% for the real estate agency and the commission rate for the agent is 30​% of the amount the real estate agency gets. How much did the agency make on the​ house? How much did the agent earn in​ commission?

Answers

Answer 1

Answer: The commission rate for the real estate agency is 7.5% of the sale price, which is:

0.075 x 343000 = $25,725

The agent's commission is 30% of the amount the agency gets, which is:

0.3 x 25725 = $7,717.50

Therefore, the real estate agency made $25,725 on the house and the agent earned a commission of $7,717.50.

What is the value of {-4,6]?

Answers

The value of {-4,6} is -4.

The braces {} create a set.

The elements in a set are written inside the braces.

When a set contains only two elements, it is considered a set with two elements or a pair of elements.

In this case, the braces {-4,6} contain two elements: -4 and 6.

Thus, the value of this set is the union of these two elements, which in this case is the sum of the two elements: -4 + 6 = 2

The process of solve of the quadratic equation is not correct. As the product of x and (2x+5) is equal to 12. Thus the value of x or 2x+5 never equals to 12. The solutions of the quadratic equation are 4, -3/2

What is an equation?

A mathematical equation is a formula that uses the equals sign to express the equality of two expressions.

The given quadratic equation is

2x² + 5x = 12

2(x² + (5/2)x) = 12

Divide both sides by 2:

x² + (5/2)x = 6

x² + 2 ×(5/4)x +  (5/4)² = 6 +  (5/4)²

(x + (5/4))² = 6 +  (25/16)

(x + (5/4))² = 121/16

(3 1/2 hours) how many minutes?

Answers

Answer:

210 minutes

Step-by-step explanation:

We know that 1 hour = 60 minutes.

3 hours = 3 * 60 = 180 minutes

1/2 hour = 1/2 * 60 minutes = 30 minutes

3 1/2 hours = 180+30 = 210 minutes

Answer:

210 minutes

Step-by-step explanation:

To convert from hours to minutes, we can multiply by a conversion ratio:

[tex]\left(3 \dfrac{1}{2} \text{ hr}\right)\left(\dfrac{60 \text{ min}}{1 \text{ hr}}\right)[/tex]

↓ converting the mixed number to a fraction

[tex]\left(\dfrac{7}{2} \text{ hr}\right)\left(\dfrac{60 \text{ min}}{1 \text{ hr}}\right)[/tex]

↓ canceling the hours unit

[tex]\dfrac{7}{2} \cdot 60 \text{ min}[/tex]

↓ multiplying

[tex]\boxed{210\text{ min}}[/tex]

Note: When we multiply something by a conversion ratio, we are not changing the value of it, but rather changing its form. In other words, a conversion ratios has a value of 1, and anything multiplied by 1 is itself. To illustrate this:

[tex]\dfrac{60 \text{ min}}{1 \text{ hr}} = \dfrac{60 \text{ min}}{60\text{ min}} = \dfrac{1}{1} = 1[/tex]

Calculate the rate of change for each function over the interval [1, 4], then tell which function is growing faster.
f (x)=3x+1
g(x)=3^x+1

Answers

Each function's rate of change across the interval [1, 4] is 3 for f(x) and 26 for g(x), respectively. As a result, g(x) is the function that is expanding more quickly.

To calculate the rate of change for each function over the interval [1, 4], we need to find the slope of the secant line between the points (1, f(1)) and (4, f(4)) for function f(x) and between the points (1, g(1)) and (4, g(4)) for function g(x).

For function f(x) = 3x + 1:

f(1) = 3(1) + 1 = 4

f(4) = 3(4) + 1 = 13

The slope of the secant line is:

(f(4) - f(1))/(4 - 1) = (13 - 4)/3 = 3

Therefore, the rate of change for f(x) over the interval [1, 4] is 3.

For function g(x) = 3^x + 1:

g(1) = 3^1 + 1 = 4

g(4) = 3^4 + 1 = 82

The slope of the secant line is:

(g(4) - g(1))/(4 - 1) = (82 - 4)/3 = 26

Therefore, the rate of change for g(x) over the interval [1, 4] is 26.

Comparing the rates of change, we see that the rate of change for f(x) is 3 and the rate of change for g(x) is 26. Therefore, the correct answer is (d) f(x) has a rate of change of 3 and g(x) has a rate of change of 26, so g(x) is growing faster.

The complete question is:-

Calculate the rate of change for each function over the interval [1, 4], then tell which function is growing faster.

f (x)=3x+1

g(x)=3^x+1

a) f(x) has a rate of change of 3

g(x) has a rate of change of 1

so f(x) is growing faster

(b) f(x) has a rate of change of 3

g(x) has a rate of change of 3

so they are growing at the same rate

(c) f(x) has a rate of change of 3

g(x) has a rate of change of 26

so f(x) is growing faster

d) f(x) has a rate of change of 3

g(x) has a rate of change of 26

so g(x) is growing faster

Using chain rule, the derivative of the function is 1 / [4x^(3/4) (1 + x^(1/2))].

What is the derivative of the function?

Let u(x) = √4. Then we can write the given function as d/dx[tan^-1(u(x))].

Recall that the chain rule for differentiation states that d/dx[f(g(x))] = f'(g(x)) * g'(x). Applying this to our function, we have:

d/dx[tan^-1(u(x))] = [d/dx(tan^-1(u))] * [d/dx(u(x))]

To find d/dx(tan^-1(u)), we use the formula for the derivative of the inverse tangent function: d/dx[tan^-1(u)] = u'(x) / [1 + u(x)^2].

To find u'(x), we differentiate u(x) = sqrt4 with respect to x using the chain rule as follows:

d/dx[√4] = (1/2)x^(-3/4) * (d/dx)(x) = (1/2)x^(-3/4)

Therefore, u'(x) = (1/2)x^(-3/4).

Substituting u(x) and u'(x) into the formula for the derivative of the inverse tangent function, we get:

d/dx[tan^-1(u(x))] = [1 / (2x^(3/4) * (1 + x))]

Finally, substituting this expression for d/dx(tan^-1(u)) and d/dx(u(x)) back into our original chain rule expression from step 2, we get:

d/dx[tan^-1(√4)] = [1 / (2x^(3/4) * (1 + x))] * (1/4)x^(-3/4)

Simplifying the expression in step 6 by multiplying the two terms in the denominator and bringing x to the common denominator, we get:

d/dx[tan^-1(√4)] = 1 / [4x^(3/4) (1 + x^(1/2))]

Therefore, the derivative of the function d/dx[tan^-1(√4)] is 1 / [4x^(3/4) (1 + x^(1/2))].

product A and BUYS 13 of product B. At the end of the business day, John banks Ksh 110,000/- while
Tom banks Ksh 230,000.
Under the assumption that the sale prices for product A and B are the same for the two men, and the costs prices for the products A and B are also the same for the two men, obtain the following:
The price for product A which was determined as Ksh 42,727.27 and the price for product B as 44,363.63

Question: If there was a mark up of 25% on the cost price and a discount of 15% on the sale price, how
much would each of the partners have banked at the end of the business day?

Answers

So, Tom would have earned *Ksh (137465.91 + x) and John would have earned Ksh (202533.09 - x)

What exactly is markup?

The sum that is added to a product's cost price to cover expenses and profit is known as a markup.

We are aware that John banks 100,000 and Tom 230,000 Kenyan shillings.

Assume that both product A and B have a cost price of x.

Tom spends 5x because he BUYS 5 of Product A.

Tom sells two times as much of B. He SELLS 2 * (2x) = 4x as a result.

Hence, Tom's gain is:

4x - 5x = -x

Tom suffers a loss of x as a result of this.

John sells product A for three times what Tom BOUGHT. Thus he SELLS 3 * 5 = 15 times.

John purchases 13 of B Product. He therefore spends 13 times.

John thus makes a profit of:

15x - 13x = 2x

John thereby benefits by a factor of two.  

As a result, the cost of goods A and B is:

42,727.27 + (25/100) * 42,727.27 = Ksh 53,409.09

44,363.63 + (25/100) * 44,363.63 = Ksh 55,454.54

We also know that the sale price was discounted by 15%.

After discounts, the sale price for item

A is (85/100) * Ksh 53,409.09, which is Ksh 45,397.73.

After discounts, the sale price for item

B is (85/100) * Ksh 55,454.54 = Ksh 47,136.36.

Tom's product loss

Ksh 45,397.73 - x = cost price - selling price

John's profit on item A is calculated as follows:

sale price less cost price = Ksh 45,397.73 - x

Cost price minus sale price equals Tom's loss on item B, which is Ksh 47,136.36.

John's profit on item B is calculated as follows: sale price less cost price = Ksh 47,136.36 - x

Therefore:

Total loss for Tom is (x - Ksh 45,397.73) + (x - Ksh 47,136.36)

= 2x - Ksh (45,397.73 + 47,136.36)

= = 2x - Ksh (92,534.09) (92,534.09)

(Ksh 45,397.73 - x) + John's total profit (Ksh 47,136.36 - x)

= Ksh (92,533.09) -2x

After discount and markup, Tom's bank balance equals Tom's bank balance plus his overall loss.

= [2x - Ksh (92,534.09)] + Ksh (230000)

= Ksh (137465.91 + x)

After discount and markup, John's bank balance equals John's bank balance plus his overall profit.

= [Ksh (92,533.09) -2x) + Ksh (110000)]

= Ksh (202533.09 - x)

Therefore, we can say that there is a 95% chance that a randomly selected light bulb will last between 675 and 900 hours.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a mathematical concept that is used to quantify the chance of a specific outcome in a given situation. Probability is typically expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain to occur.

Here,

To solve this problem, we can use the z-score formula:

z = (x - mu) / sigma

where x is the value we want to find the probability for (in this case, between 675 and 900 hours), mu is the mean (750 hours), and sigma is the standard deviation (75 hours). We can then use a standard normal distribution table or calculator to find the probabilities associated with the calculated z-scores.

First, let's find the z-score for x = 675:

z = (675 - 750) / 75

= -1

Next, let's find the z-score for x = 900:

z = (900 - 750) / 75

2

Since the data is normally distributed, we can use this rule to estimate the probability that a randomly selected light bulb will last between 675 and 900 hours.

Thus, the probability that a randomly selected light bulb will last between 675 and 900 hours is approximately:

What is mean?

The mean, often known as the arithmetic mean, is a statistic that expresses the central tendency of a collection of numerical data.

It is calculated by summing up all of the dataset's values and dividing the result by the total number of values.

Since it gives a single value that summarises the entire dataset, the mean is frequently employed as a typical value for a dataset.

Outliers in the dataset, however, have the potential to have an impact.

We must first establish the quartiles in order to determine the interquartile range (IQR) for each block.

This can be accomplished by first determining the median (Q2) of each block, followed by the medians of the lower (Q1) and upper (Q3) halves of the data.

Block 1's:

Q1: median of {25, 60, 70, 75, 80} = 70

Q2: median of {85, 85, 90, 95, 100} = 90

Q3: median of {70, 75, 80, 85, 90} = 80

IQR = Q3 - Q1 = 80 - 70 = 10

Block 2's:

Q1: median of {70, 70, 75, 75, 75} = 75

Q2: median of {75, 75, 80, 80, 85} = 80

Q3: median of {80, 85, 100, 75, 75} = 82.5

The smallest common denominator for 3, 69, and 23 is 3 x 69 x 23 = 15087. So we rewrite each fraction with the common denominator: 17/3 x 5039/5039 = 85763/15087 29/69 x 219/219 = 633/15087 139/23 x 657/657 = 9123/15087

The difference between two numbers is 47. Two times

Answers

Answer:

Let's call the smaller number "x" and the larger number "y". We know that:

y - x = 47 (Equation 1)

And also, we know that:

2x = y + 22 (Equation 2)

We can solve this system of equations by substituting the expression for "y" from Equation 1 into Equation 2:

2x = (x + 47) + 22

Simplifying this equation, we get:

2x = x + 69

Subtracting "x" from both sides, we get:

x = 69

Now we can use Equation 1 to find the value of "y":

y - 69 = 47

y = 47 + 69

y = 116

Therefore, the two numbers are 69 and 116.

The numbers are 25 and 72.

Let the smaller number be x.

As the difference between smaller and larger number is 47, the larger number is 47 more than smaller.

The larger number = x+47.

Now, according to question,

two times the smaller number is 22 more than the larger number.

two times the smaller number=2x

Larger number=2x+22

2x+22=x+47 (as the larger number is x+47)

⇒ 2x-x=47-22   ( transferring variables on LHS and constants on RHS)

⇒ x=25

∴ the smaller number is 25

and the larger number = x+47=25+47

                                       =72

Hence, the smaller number is 25 and the larger number is 72.

Think about setting up a code for 24 letters (all of the letters in the alphabet except for O and I) with a two-number code for each letter. What are the pros and cons of assigning codes randomly vs. systematically?

Answers

Random codes reduce biases and increase security, but may be hard to use and result in inefficient coding. Systematic codes are easier to organize and use, but may be more predictable and less secure. The choice depends on needs and trade-offs between security, efficiency, and ease of use.

Assigning codes randomly:

Pros:

Reduces the likelihood of biases or patterns in the code assignment

Difficult to guess or predict the code for a given letter, increasing security

Cons:

May not be intuitive or easy to remember for users

Difficult to organize or sort codes in a meaningful way

May result in inefficient coding with long or repetitive codes

Assigning codes systematically:

Pros:

Easier to organize and sort codes alphabetically or by other criteria

Can be more intuitive and easy to remember for users

Can result in shorter or more efficient codes

Cons:

May be more susceptible to patterns or biases in the code assignment

May be easier to guess or predict the code for a given letter, reducing security

Ultimately, the choice of whether to assign codes randomly or systematically depends on the specific needs and goals of the coding system, as well as the trade-offs between security, efficiency, and ease of use.

Rewrite the fractions 2/5 and 4/15 as fractions with a least common denominator

Answers

Answer:

Step-by-step explanation:

To rewrite the fractions 2/5 and 4/15 with a least common denominator, we need to find the least common multiple (LCM) of their denominators, which is 15.

For 2/5, we can multiply the numerator and denominator by 3 to get:

2/5 = (2 x 3)/(5 x 3) = 6/15

For 4/15, we don't need to do anything since its denominator is already 15.

Therefore, the equivalent fractions with a least common denominator are:

2/5 = 6/15

4/15 = 4/15

for #10: evaluate double integral by converting to polar coordinates:

Answers

The solutions to the equation:

8. The value of the integral is 0.

9. The value of the integral is approximately -0.336.

10. The value of the integral is π(b - a)/4

11. The value of the integral is π/4 - (1/2)(1 - e^4).

12. The value of the integral is -8π.

13. The value of the integral is π/64 + π/(32√2).

How did we get these values?

8. To evaluate the integral ∫∫R(2x-y) dA over the region R in the first quadrant enclosed by the circle x² + y² = 4 and the lines x= 0 and y=x, we can use polar coordinates.

First, we convert the equations of the circle and line into polar coordinates:

x² + y² = 4 becomes r² = 4

y = x becomes θ = π/4

The region R can be described in polar coordinates as 0 ≤ r ≤ 2 and 0 ≤ θ ≤ π/4. The differential element dA can be expressed in polar coordinates as dA = r dr dθ.

Now we can evaluate the integral:

∫∫R(2x-y) dA = ∫₀^(π/4) ∫₀² (2r²cosθ - rsinθ) r dr dθ

= ∫₀^(π/4) ∫₀² (2r³cosθ - r²sinθ) dr dθ

= ∫₀^(π/4) [r⁴cosθ/2 - r³sinθ/3]₀² dθ

= ∫₀^(π/4) 8cosθ/3 - 8sinθ/3 dθ

= [8/3(sinθ - cosθ)]₀^(π/4)

= 8/3(1/√2 - 1/√2 - (0 - 0))

= 0

Therefore, the value of the integral is 0.

9. To evaluate the integral ∫∫Rsin(x² + y²) dA over the region R in the first quadrant between the circles with center the origin and radii 1 and 3, we can again use polar coordinates.

In polar coordinates, the region R can be described as 1 ≤ r ≤ 3 and 0 ≤ θ ≤ π/2. The differential element dA can be expressed as dA = r dr dθ.

Now we can evaluate the integral:

∫∫Rsin(x² + y²) dA = ∫₀^(π/2) ∫₁³ r sin(r²) dr dθ

= ∫₀^(π/2) [-cos(r²)]₁³ dθ

= ∫₀^(π/2) cos(1) - cos(9) dθ

= sin(1) - sin(9)

≈ -0.336

Therefore, the value of the integral is approximately -0.336.

10. To evaluate the integral ∫∫R y²/x² + y²dA over the region that lies between the circles x² + y² = a² and x² + y² = b² with 0 < a < b, we can use polar coordinates.

In polar coordinates, the region R can be described as a ≤ r ≤ b and 0 ≤ θ ≤ 2π. The differential element dA can be expressed as dA = r dr dθ.

Now we can evaluate the integral:

∫∫R y²/x² + y²dA = ∫₀^(2π) ∫ₐᵇ (r⁴cos²θsin²θ)/(r⁴cos²θ) r dr dθ

= ∫₀^(2π) ∫ₐᵇ sin²θ cos²θ dr dθ

= ∫₀^(2π) [(b-a)/4](cos²θ - sin²θ) d

= ∫₀^(2π) [(b-a)/4](cos²θ - sin²θ) dθ

= [(b-a)/8] ∫₀^(2π) (1 - sin(2θ)) dθ

= [(b-a)/8] (2π - 0)

= π(b - a)/4

Therefore, the value of the integral is π(b - a)/4.

11. To evaluate the integral ∫∫D e^(-x²-y²) dA, where D is the region bounded by the semicircle x = √(4 - y²) and the y-axis, we can use polar coordinates.

In polar coordinates, the region D can be described as 0 ≤ r ≤ 2 and 0 ≤ θ ≤ π/2. The differential element dA can be expressed as dA = r dr dθ.

Now we can evaluate the integral:

∫∫D e^(-x²-y²) dA = ∫₀^(π/2) ∫₀² e^(-r²) r dr dθ

= ∫₀^(π/2) [-1/2 e^(-r²)]₀² dθ

= ∫₀^(π/2) (1/2 - 1/2e^4) dθ

= π/4 - (1/2)(1 - e^4)

Therefore, the value of the integral is π/4 - (1/2)(1 - e^4).

12. To evaluate the integral ∫∫D cos(√(x²+y²)) dA, where D is the disk with center at the origin and radius 2, we can again use polar coordinates.

In polar coordinates, the region D can be described as 0 ≤ r ≤ 2 and 0 ≤ θ ≤ 2π. The differential element dA can be expressed as dA = r dr dθ.

Now we can evaluate the integral:

∫∫D cos(√(x²+y²)) dA = ∫₀^(2π) ∫₀² r cos(r) dr dθ

= ∫₀^(2π) [2 sin(r) - 2r cos(r)]₀² dθ

= ∫₀^(2π) (-4) dθ

= -8π

Therefore, the value of the integral is -8π.

13. To evaluate the integral ∫∫R arctan(y/x) dA, where R = {(x,y) | 1 ≤ x² + y² ≤ 4, 0 ≤ y ≤ x}, we can use polar coordinates.

In polar coordinates, the region R can be described as π/4 ≤ θ ≤ π/2 and 1/√2 ≤ r ≤ 2. The differential element dA can be expressed as dA = r dr dθ.

Now we can evaluate the integral:

∫∫R arctan(y/x) dA = ∫π/4^(π/2) ∫1/√2² r arctan(tan(θ)) dr dθ

= ∫π/4^(π/2) [(r²θ/2 - r²tan(θ)/4)]1/√2² dθ

= ∫π/4^(π/2) [(2θ - π/2)/8] dθ

= [θ²/16 - (θ - π/4)/8]π/4^(π/2

= [π/16 - (π/4 - π/4√2)/8] - [(π/16 - (π/8 - π/8√2)/8)]

= π/64 + π/(32√2)

Therefore, the value of the integral is π/64 + π/(32√2).

The smaller train is a scale drawing of the larger train is the length of the tire rod connecting the three tires of the larger chain as shown below is 36 inches right in equation to find the length of the tire rod of the smaller chain interpret your solution in the context of the problem.

Answers

the tire rod of the smaller train would be 3.6 inches long if the scale factor is 10.

What is the constant of proportionality?

The constant of proportionality is a term that is defined as the rate or the ratio of two proportional values which are known to be at the same value.

we can set up the following proportion:

(Larger train tire rod length) / (Larger train length) = (Smaller train tire rod length) / (Smaller train length)

Substituting the given values, we have:

36 / (Larger train length) = x / (Smaller train length)

Since we don't know the exact lengths of the larger and smaller trains, we cannot solve for x directly. However, we can use the fact that the smaller train is a scale drawing of the larger train to set up another proportion:

(Larger train length) / (Smaller train length) = (Scale factor)

Let the scale factor be s. Then we can rewrite the above proportion as:

(Larger train length) = s x (Smaller train length)

Substituting this expression into the first proportion, we have:

36 / (s x Smaller train length) = x / (Smaller train length)

Simplifying, we get:

x = 36 / s

x = 36 / 10 = 3.6 inches

In other words, the tire rod of the smaller train would be 3.6 inches long if the scale factor is 10.

Answers

The probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 53/115, or approximately 0.4609 when rounded to four decimal places.

What is probability?

We can use conditional probability to find the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience:

P(Graduate degree | Over 5 years of experience) = P(Graduate degree and Over 5 years of experience) / P(Over 5 years of experience)

We are given that 53 applicants have both a graduate degree and over 5 years of experience, so:

P(Graduate degree and Over 5 years of experience) = 53/491

We are also given that 115 applicants have over 5 years of experience, so:

P(Over 5 years of experience) = 115/491

Now we can substitute these values into the formula:

P(Graduate degree | Over 5 years of experience) = (53/491) / (115/491)

Simplifying, we get:

P(Graduate degree | Over 5 years of experience) = 53/115

So the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 53/115, or approximately 0.4609 when rounded to four decimal places.

The area of a circle is given by the formula

[tex]A = πr^2.[/tex]

To find the area of the shaded region, we need to subtract the area of the smaller circle from the larger circle:
Shaded area = [tex]πr^2 - πa^2[/tex]
However, we're not done yet because we need to simplify this expression in terms of "a" and in simplified radical form. To do this, we can factor out π from both terms:

What is probability?

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% because there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many fields, including statistics, economics, science, and engineering.

The X-axis represents the time between vehicle arrivals, and the Y-axis represents the probability density. The peak of the distribution is at 12 seconds, which is the mean.

b. Probability of the arrival time between vehicles being 12 seconds or less:

Since the mean of the exponential distribution is 12 seconds, we can use the cumulative distribution function (CDF) to find the probability of the arrival time being 12 seconds or less:

[tex]P(X < = 12) = 1 - e^(-12/12) = 1 - e^(-1) ≈ 0.6321[/tex]

Therefore, the probability of the arrival time between vehicles being 12 seconds or less is approximately 0.6321.

c. Probability of the arrival time between vehicles being 6 seconds or less:

[tex]P(X < = 6) = 1 - e^(-6/12) = 1 - e^(-0.5) ≈ 0.3935[/tex]

Therefore, the probability of the arrival time between vehicles being 6 seconds or less is approximately 0.3935.

d. Probability of 30 or more seconds between vehicle arrivals:

[tex]P(X > = 30) = e^(-30/12) ≈ 0.0498[/tex]

What is probability?

Chance is represented by probability. The study of the occurrence of random events is the subject of this mathematical subfield. The value is expressed as a number from 0 to 1. Mathematicians have begun to use the concept of probability to predict the likelihood of certain events.

This is because there are 5 strawberry chews and 15 cherry chews in the bag, so

the probability of drawing a strawberry chew is 5/20 or 1/4, and

the probability of drawing a cherry chew is 15/20 or 3/4.

Despite the fact that neither of the outcomes has the same probability, there are only two possible outcomes
