The following data set is A population ⇒ answer A

Step-by-step explanation:

Lets revise the definition of each choice

1. A population, is a discrete group of people, animals or things that

can be identified by at least one common characteristic for the

purposes of data collection

2. A sample is just a part of a population

3. The parameter is a fixed measure which describes the target population

Parameter is a fixed and unknown numerical value

4. A statistic is a characteristic of a small part of the population

The statistic is a variable and known number which depend on the

sample of the population

∵ All of the teachers in Gwinnett County Public Schools fill out the

  survey

∴ The data set is population

The following data set is A population

Use the pythagoren theorem to solve x
defon
Well the equation is (A^2)+(B^2)=(C^2)

A= x
B= 2x
C will always be the longest side because it is the Hypotenuse = 25

So if you plug in those numbers into the equation...

(x^2) + (2x^2) = (25^2)

x^2 + 4x^2 = 625

Combine like terms

5x^2 = 625

Divide by five to both sides

x^2 = 125

Then Square root,

x = sqrt(125)

x = sqrt(25* 5)

x = 5sqrt(5)

What is the rate of change of the linear relationship modeled in the table (-2,5) (-1,4) (0,3) (1,2)
poizon [28]

The rate of change of the linear relationship is -1.

Explanation:

It is given that there is a linear relationship between all these points, these points lie on a straight line.

The equation to find the slope passing through two points \left(x_{1}, y_{1}\right) and \left(x_{2}, y_{2}\right) is given by

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the points (-2,5) and (-1,4), we get,

\begin{aligned}m &=\frac{4-5}{-1+2} \\&=\frac{-1}{1} \\&=-1\end{aligned}

Thus, the slope is -1.

Thus, the rate of change of the linear relationship is -1.
