Samantha waters her tomato plants once a week with between 15 and 60 gallons of water.

Domain refers to the set of possible values that the independent variable can take. In this case, the domain is the range of possible amounts of water that Samantha can use to water her tomato plants, which is 15 to 60 gallons.

The independent variable is the variable that is being manipulated or controlled by Samantha, which in this case is the amount of water used to water the tomato plants. So, the independent variable is "gallons of water used".

The dependent variable is the variable that is being measured or observed, which in this case is the number of tomatoes produced each week. So, the dependent variable is the "number of tomatoes produced".

LINEAR PROGRAMMING: WHAT IS IT?

A mathematical method called linear programming is used to maximise a linear objective function under the restrictions of linear equality and inequality. In a mathematical model whose requirements are expressed by linear connections, it is used to identify the best result.

With linear programming, this issue can be resolved.

Please define x as the quantity of Type I pencils produced and y as the quantity of Type II pencils produced.

Profit = 3x + 5y is the formula for the goal function.

2x + 5y 660 are the restrictions (sanding constraint)

(Polishing constraint): x ≥0 y≥ 0; 6x + 3y 730

Under these limitations, we wish to maximize the profit function.

The largest profit comes when x = 100 and y = 80,

with a profit of $740, according to software that can solve linear programming issues or a graphing calculator.

Answer:

Step-by-step explanation:

Since A and B are independent events, we can use the formula:

P(A ∩ B) = P(A) x P(B)

P(A ∩ B) = 0.10 x 0.60

P(A ∩ B) = 0.06

So the probability of both events A and B occurring is 0.06.

To find P(A U B), we can use the formula:

P(A U B) = P(A) + P(B) - P(A ∩ B)

P(A U B) = 0.10 + 0.60 - 0.06

P(A U B) = 0.64

Therefore, the probability of either A or B occurring (or both) is 0.64.

Step-by-step explanation:

Starting with 72x5/12:

72x5/12 = (72/12) x 5 (simplifying the fraction)

= 6 x 5

= 30

Now, we have:

30 = ?x5x1/12

Multiplying both sides by 12, we get:

30 x 12 = ? x 5 x 1

360 = ? x 5

Dividing both sides by 5, we get:

72 = ?

Therefore, the missing value is 72.

The Griffins ended up paying a total of $575,647.60 for the house. The Griffins paid a total of $331,647.60 in interest over the 30-year period

Interest rate refers to the percentage of the principal amount charged by a lender to a borrower for the use of money over a certain period of time.

(a) The total amount they ended up paying for the house can be calculated by adding the down payment to the total amount paid in monthly mortgage payments over the 30-year period:

Total amount paid = down payment + (monthly payment x number of payments)

Number of payments = 30 years x 12 months/year

                                    = 360

Total amount paid = $48,000 + ($1462.91 x 360)

                               = $48,000 + $527,647.60

                               = $575,647.60

Therefore, the Griffins ended up paying a total of $575,647.60 for the house.

(b) The total amount of interest paid on the mortgage can be calculated by subtracting the amount borrowed (i.e., the purchase price minus the down payment) from the total amount paid over the 30-year period:

Total interest paid = total amount paid - amount borrowed

Amount borrowed = $292,000 - $48,000 = $244,000

Total interest paid = $575,647.60 - $244,000 = $331,647.60

Therefore, the Griffins paid a total of $331,647.60 in interest over the 30-year period.

The rule for f in the desired form is: f(x) = (3x^2 + 12x + 13r(x) + 52) / (x + 4)

To rewrite the rule for f in the form f(x) = q(x) + d(r), we need to first write g(x) in terms of r(x).

We know that g(x) = r(x) / (x + 4) + 1, so we can rewrite it as:

g(x) = r(x) / (x + 4) + (x + 4) / (x + 4)

g(x) = (r(x) + x + 4) / (x + 4)

Now, we can see that f(x) is a transformation of g(x) with q(x) = 3x and d(r) = 13. So, we can write:

f(x) = q(x) + d(r)

f(x) = 3x + 13(r(x) + x + 4) / (x + 4)

f(x) = (3x(x + 4) + 13r(x) + 52) / (x + 4)

The linear inequality for the shaded region with slope -4 is:

[tex]y < -4x + 4[/tex]

In mathematics, a linear inequality is an inequality involving a linear function in one or more variables. It describes a region in the coordinate plane that satisfies the inequality.

In mathematics, the slope is a measure of the steepness of a line. It describes how much a line rises or falls as we move from left to right along it.

According to the given information,

To write the linear inequality for the graph passing through points (0,4) and (1,0), we need to find the equation of the line first.

The slope of the line passing through these two points is:

[tex]m = (y_{2} - y_{1} ) / (x_{2} - x_{1})[/tex]

= (0 - 4) / (1 - 0)

= -4

Using the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept, we can find the equation of the line passing through these two points:

[tex]y = -4x + 4[/tex]

Now, to write the linear inequality for this line, we need to determine which side of the line is shaded. We can use the test point (0,0) to check which side of the line contains the solutions to the inequality.

If we plug in (0,0) into the equation [tex]y = -4x + 4[/tex], we get:

0 = -4(0) + 4

0 = 4

Since 0 is not less than 4, the point (0,0) is not a solution to the inequality. Therefore, we need to shade the side of the line that does not contain the origin (0,0).

The linear inequality for the shaded region is:

[tex]y < -4x + 4[/tex]

So any point below the line [tex]y = -4x + 4[/tex]satisfies this inequality.

The Triangle Proportionality Theorem, also known as the Side Splitter Theorem, states that if a line is parallel to one side of a triangle, then it divides the other two sides proportionally.

Triangle Proportionality Theorem:

To prove this theorem, we begin by drawing a ΔABC with a line DE parallel to side AB. We then draw lines BD and CE, which intersect the parallel line DE at points F and G, respectively. By the properties of parallel lines, we know that ∠ADE and ∠ABD are congruent, and ∠AED and ∠ADB are congruent. Similarly, ∠CDE and ∠BDC are congruent, and ∠CED and ∠DCB are congruent.

We can then use the properties of similar triangles to show that ΔADE and ΔABC are similar, as are  ΔCDE and ΔACB. This means that the ratios of corresponding side lengths are equal:

BA/DE = CA/CE and CB/DE = AB/BD

We can then substitute CA - BA for CB in the first equation, and BD for AB in the second equation:

BA/DE = (CA - BA)/CE and CB/DE = BD/(CA - BA)

Cross-multiplying both equations, we obtain:

BA * CE = DE * (CA - BA) and CB * DE = BD * (CA - BA)

Adding the two equations, we get:

BA * CE + CB * DE = (DE + CE) * CA

Dividing both sides by CB * DE, we obtain:

BA/CB = (DE + CE)/CE * CA/DE = DE/CD

Thus, we have proven the Triangle Proportionality Theorem.

What is Histogram ?

A histogram is a graphical representation of the distribution of a dataset. It is a way to display the frequency of occurrence of different values or ranges of values in a dataset.

The correct answer is IQR, because it is more robust to outliers and is not affected by extreme values like Range.

Although the question provides information about the shape of the histograms, it does not indicate whether the distributions are symmetric or skewed. Therefore, the choice of IQR over Range is not based on the shape of the data but on the fact that IQR is a more appropriate measure of variability when dealing with skewed data or data with outliers.

In general, the IQR is a better measure of variability than the range when the data is skewed or contains outliers, as it only considers the middle 50% of the data and is not affected by extreme values.

The tangent function has vertical asymptotes at odd multiples of π/2, which means that the function is undefined at those points. Therefore, the graph has vertical asymptotes at x = π/2, 3π/2, 5π/2, ....

The function also has zeros at even multiples of π, which occur when tan(x/2) = 0. This happens when x/2 = kπ where k is an integer, so x = 2kπ.

Between each pair of vertical asymptotes, the function oscillates between positive and negative infinity. The function is positive in the intervals (2kπ, (2k+1)π) and negative in the intervals ((2k-1)π, 2kπ) for all integers k.

b. Value of x is 12.5 and maximum revenue produces $468.75

c. Wholesale price/chip that produces the maximum revenue is $37.50

A company's or business's revenue is the total amount of money it receives from sales of its products or services over a given time period.

a) To sketch a graph of the revenue function R(x), we first need to calculate R(x) using the given formula:

⇒ R(x) = x P(x)

⇒ R(x) = x(75 - 3x)

⇒ R(x) = 75x - 3x²

Now we can plot this function on a rectangular coordinate system. Below is an sketch of the graph.

b) Taking the derivative of R(x) and setting it equal to 0:

⇒ R'(x) = 75 - 6x = 0

⇒ 6x = 75

⇒  x = 12.5

So, x = 12.5 is the value of x that will produce the maximum revenue. To find the maximum revenue, we can substitute x = 12.5 into the revenue function R(x) = x (75 - 3x)

⇒ R(12.5) = 12.5 (75 - 3 (12.5)) = 468.75

⇒ R(12.5) = $ 468.75

Therefore, the maximum revenue is $468.75

c) To find the wholesale price per chip that produces the maximum revenue, we can substitute x = 12.5 into the price function, P(x) = 75 - 3x​

⇒ P(12.5) = 75 - 3(12.5)

⇒ P(12.5) =  $37.50 per chip

Therefore, the wholesale price per chip that produces the maximum revenue is $37.50.

So the area of the living room on the scale drawing is 334128.48 square centimeters.

Area is a measure of the size of a two-dimensional surface or region, typically expressed in square units. It is the amount of space inside a flat, enclosed shape or surface, and is calculated by multiplying the length and width of the shape or surface. For example, the area of a rectangle can be calculated by multiplying its length by its width, while the area of a circle can be calculated by multiplying pi (3.14) by the square of its radius. Area is a fundamental concept in mathematics and is used in a wide range of fields, from geometry and physics to engineering and architecture.

Here,

First, we need to determine the actual dimensions of the living room. Since each 4 cm on the scale drawing is equal to 8 feet, we can set up a proportion:

4 cm : 8 feet = 12 cm : x

Solving for x, we get:

x = (12 cm x 8 feet) / 4 cm

= 24 feet

So the actual length and width of the living room are 24 feet and 24 feet, respectively.

The area of the living room is then:

Area = length x width

= 24 feet x 24 feet

= 576 square feet

Now, we need to determine the area of the living room on the scale drawing. Since the length and width of the scale drawing are both 12 cm, the area is:

Area = length x width

= 12 cm x 12 cm

= 144 square cm

Finally, we can determine the scale factor for the area by dividing the actual area by the scale area:

Scale factor = actual area / scale area

= 576 square feet / 144 square cm

Since we need the area in square centimeters, we can convert square feet to square centimeters by multiplying by 929.03:

Scale factor = (576 square feet / 144 square cm) x (929.03 square cm/square feet)

= 2324.12

Therefore, the area of the living room on the scale drawing is:

Area = scale area x scale factor

= 144 square cm x 2324.12

= 334128.48 square cm

Answer: (7.2, -3.2)

Step-by-step explanation:

         First, we will graph these equations. See attached. One has a y-intercept of -5 and then moves four units right for every unit up (we get this from the slope of 1/4). The other has a y-intercept of 4, and moves right one unit for every unit down (we get this from the slope of -1).

         The point of intersection is the solution, this is the point at which both graphed lines cross each other. Our solution is:

                         (7.2, -3.2)     x = 7.2, y = -3.2

Answer: 15 inches

Step-by-step explanation:

An equilateral triangle has three equal sides, so if the perimeter of the triangle is 45 inches, then each side must be 45 inches divided by 3, which gives us:

45 in ÷ 3 = 15 in

Therefore, the length of each side of the flag is 15 inches.

Answer:

The selling price of the automobile after the $500 rebate is:

$18,340 - $500 = $17,840

The markdown is the difference between the original selling price and the selling price after the rebate, expressed as a percentage of the original selling price. The markdown can be calculated as follows:

Markdown = [(Original Price - Discounted Price) / Original Price] × 100%

Markdown = [(18,340 - 17,840) / 18,340] × 100%

Markdown = (500 / 18,340) × 100%

Markdown ≈ 2.72%

Rounding to the nearest tenth of a percent, the percent markdown is approximately 2.7%.
