We need to round up to the next higher integer, the sample size required to estimate the mean with an error of +4 and 95 Percent confidence is 170.

To find the sample size to estimate the mean with an error of +4 and 95 percent confidence, we need to use the formula:

n = [(z*sigma)/E]^2

Where:
n = sample size
z = z-score for 95% confidence level (which is 1.96)
sigma = standard deviation (unknown in this case)
E = maximum allowable error (which is +4 in this case)

We are given that o=12, which is the population standard deviation. Since we do not have any information about the sample standard deviation, we can use the population standard deviation as an estimate. Therefore, we can substitute o=12 in the above formula to get:

n = [(1.96*12)/4]^2
n = 169.64

Since we need to round up to the next higher integer, the sample size required to estimate the mean with an error of +4 and 95 percent confidence is 170.

Step-by-step explanation:

To solve for x, we'll first need to simplify the equation by combining like terms:

0.6x - 5 = 0.1x + 7

0.6x - 0.1x = 7 + 5

0.5x = 12

x = 12 / 0.5

x = 24

Therefore, the value of x that makes the equation true is 24.

The additive inverse of the polynomial -7y² + x²y -3xy - 7x² include the following: A. 7y² - x²y + 3xy + 7x².

In Mathematics and Geometry, an additive inverse can be defined as a number (n) which when added to another number (a) makes it equal to zero (0). This ultimately implies that, an additive inverse is the opposite of another number (a).

Mathematically, an additive inverse can be represented by the following equations:

a + n = 0

a = -n

-7y² + x²y - 3xy - 7x² = -(-7y² + x²y - 3xy - 7x²)

-7y² + x²y - 3xy - 7x² = 7y² - x²y + 3xy + 7x²)

In this context, we can reasonably infer and logically deduce that an additive inverse of -7y² + x²y -3xy - 7x² is 7y² - x²y + 3xy + 7x².

Answer: The probability of reaching into the jar and retrieving a black button is 0.64. Therefore, the probability of reaching into the jar and retrieving a button that is not black is the complement of this probability, which is 1 - 0.64 = 0.36.

In other words, the probability of not getting a black button is the same as the probability of getting a non-black button, which includes all the other colored buttons in the jar. Since there are no other details given in the problem regarding the number of non-black buttons or the probability of retrieving each non-black button, we assume that they are all equally likely to be retrieved and simply calculate the probability of not getting a black button as the complement of the probability of getting a black button.

it is true that the expression (36⁴−6⁹)(38⁹−38⁸) is divisible by 30 and 37

Carl Friedrich Gauss introduced the fundamental principle of number theory in 1801, which states that any integer higher than one can be expressed as the product of prime numbers only in one way. Number theory is also referred to as arithmetic. Addition, subtraction, multiplication, and division are the four foundational operations in mathematics. Below, a quick discussion of all these operations is provided.

The expression is given as:

(36⁴−6⁹)(38⁹−38⁸)

Express 36 as 6²

(36⁴ - 6⁹) = (6²)⁴ - 6⁹

= 6⁸ - 6⁹

= 6⁷(6 - 6²)

= 6⁷(6 - 36)

= 6⁷(-30)

=(38⁹ - 38⁸)

= 38⁸(38 - 1)

= 38⁸(37)

=(36⁴−6⁹)(38⁹−38⁸)

=6⁷(-30) × 38⁸(37)

=(30)(37)(-6⁷)(38⁸)

Triangles BIG and MOP are similar so, the values of v, w, x, y are 36 cm, 156°, 46.7°, 43.2° respectively.

A triangle is a two-dimensional geometric shape that is formed by three line segments that connect three non-collinear points in a plane. These points are called the vertices of the triangle, and the line segments connecting them are called sides.

Triangles are characterized by several properties, including their side lengths, angles, and areas. Based on the lengths of their sides, triangles can be classified into three types:

Scalene triangle: A triangle in which all three sides have different lengths.

Isosceles triangle: A triangle in which two sides have the same length.

Equilateral triangle: A triangle in which all three sides have the same length.

Since triangles BIG and MOP are similar, we know that their corresponding angles are equal and their corresponding sides are proportional.

Let's first find the value of w in triangle BIG. We know that the sum of angles in a triangle is 180 degrees. Therefore, we can find angle BIG as follows:

angle BIG = 180 - angle BGI

= 180 - 24

= 156 degrees

Now we can use the fact that the corresponding sides of similar triangles are proportional to set up the following ratios:

v/42 = 48/v (since BI/IG = GB/BI)

v^2 = 4248

v = sqrt(4248)

v = 36

In triangle MOP, we can use the law of cosines to find the value of angle MOP:

cos(MOP) = (60^2 + 72^2 - y^2) / (26072)

cos(MOP) = (3600 + 5184 - y^2) / 8640

cos(MOP) = (8784 - y^2) / 8640

MOP = acos((8784 - y^2) / 8640)

MOP = 46.7 degrees (approximately)

Now we can use the fact that the corresponding sides of similar triangles are proportional to set up the following ratios:

v/60 = y/72 (since BI/MO = IG/MP)

y = (v/60)*72

y = (36/60)*72

y = 43.2 cm

Lastly, we can use the fact that the sum of angles in a triangle is 180 degrees to find the value of angle POM in triangle MOP:

angle POM = 180 - angle MOP - 126

= 180 - 46.7 - 126

= 7.3 degrees (approximately)

Therefore, we have:

v = 36 cm

w = 156 degrees

x = 46.7 degrees (approximately)

y = 43.2 cm

Answer:

Step-by-step explanation:

number of books are 5 so you will have to do 5 by hundred  which will lead to twenty percent

The likelihood that the manager will choose the longest just-received nonfiction book and the shortest recently arrived fiction book is 1/20, or 5%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

The probability of selecting the shortest fiction book is 1/5 and the probability of selecting the longest nonfiction book is 1/4. Since these events are independent, we can multiply their probabilities to find the probability of both events happening:

P(shortest fiction book and longest nonfiction book) = P(shortest fiction book) x P(longest nonfiction book) = 1/5 x 1/4 = 1/20

So the probability that the manager will select the shortest of the newly arrived fiction books and the longest of the newly arrived nonfiction books is 1/20, which is equivalent to 5%.

The length of the ramp we need to build should be at least 38.61 feet to pass code.

In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.

We can use trigonometry to solve the problem. Let x be the length of the ramp we need to build. Then, the angle the ramp makes with the ground is given by:

sin(theta) = opposite/hypotenuse

where theta is the angle the ramp makes with the ground, opposite is the vertical increase of 10 feet, and hypotenuse is the length of the ramp x.

Solving for x, we get:

x = opposite/sin(theta) = 10/sin(15)

Using a calculator, we can evaluate sin(15) to be approximately 0.2588. Then, we can divide 10 by 0.2588 to get:

In exchange for using borrowed funds or assets, a borrower must pay the lender interest. It is charged for a certain duration of time, typically until the loan is fully returned, and is typically stated as a percentage of the amount borrowed. This fee is known as the interest rate. For instance, if a bank lends you $1,000 at a 5% annual interest rate, after a year of borrowing the money you would still owe the bank $50 more in interest. The creditworthiness of the borrower, the risk of the loan, and current market conditions are frequently used to establish the interest rate.

given

We know that Fwam expects the account to be worth $91,000 in 12 years and that the interest rate is 5.9% compounded daily in this situation.

We must convert the interest rate and the time period to the proper units before we can use the formula.

We begin by converting the 5.9% yearly interest rate to a daily rate:

daily rate is equal to (1 + 0.059/365)(365/365)-(1-1) = 0.00015999.

4,380 days in 12 years, or 365 days per year.
