Step-by-step explanation:

You need to solve this because it is b divided by 2. How you solve this is to multiply all of it by 2. 20 x 2 is 40.

B=40 if that’s what your solving for
2•20 = 40 so b= 40

An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the
mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 7 IQ points of the true mean. Assume that o = 19 and
determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.

Answers

Step-by-step explanation:

To solve this question, we use this formula:

x± s t_(1−c)/2 / √n = 5

(1 - c)/2 = (1 - 0.95) / 2 = 0.025

Using a t score calculator at this value, at the 95% confidence internval,

t = 0.5080, So

100 - 19(0.5080) / √n = 5

Solving for n

n = 97

a) 97

b) yes

Which BEST describes the association between goals by the Red Team and the Blue Team?
A
nonlinear association
B
positive association
С

D

Answers

b positive association

The relation between the Red team and Blue team will be a non-linear association. Then the correct option is A.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The table is shown below.

The association between the goals of the Red Team and the Blue Team will be given in the table.

Let the line passes through the point (1, 1) and (4, 9). Then we have

y - 1 = 8/3(x - 1)

y - 3 = 8x - 8

    y = 8x - 5

But all the points present between the (1, 1) and (4, 9) do not lie on the line. Then the relation between the Red team and the Blue team will be a non-linear association.

More about the linear system link is given below.

5. Find the perimeter and area of the parallelogram. Round to the nearest tenth if necessary.

Answers

Answer:

perimeter: 23.6yd

area: 34.3yd²

Step-by-step explanation:

This is technically a rectangle, but alrighty, so for the perimeter, you just add all the sides together, or multiply, blah blah blah, no here:

5.2 x 2 + 6.6 x 2 = 23.6

So the perimeter is 23.6yd

Now, we find the area by multiplying the width by the height (i think that's the right terminology, so you basically just multiply the only number's there:

5.2 x 6.6 = 34.32

But then we round to the tenth and 2 rounds down to 34.3, so the area is 34.3yd²
