The graph below represents a population

Nataliya [291]

Answer:

Average rate of change for the function for the interval (6, 12] is 500 people per year.

Option A is correct.

Step-by-step explanation:

We need to find the average rate of change for the function for the interval

(6, 12]

The formula used to calculate Average rate of change is:

$Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}$

We are given a=6 and b=12

Looking at the graph we can see that when x=6 y= 3000 so, f(a)=3000

and when x=12, y=6000 so, f(b)=6000

Putting values in formula and finding Average rate of change:

$Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{6000-3000}{12-6}\\Average \ rate \ of \ change=\frac{3000}{6}\\Average \ rate \ of \ change=500$

So, average rate of change for the function for the interval (6, 12] is 500 people per year.

Option A is correct.

I doubt the options you've mentioned here.
The correct answer should be x=a/b

2.) If a researcher uncovers a relationship between class (independent variable) and prejudice (dependent variable), what can be

nirvana33 [79]

Answer:

Step-by-step explanation:

Correlation measures the strength of the linear relationship between two variables.

A linear relationship exists between two variables if one variable increases as the other increases or decreases.

Use the formula for correlation coefficient to determine the strength of the relationship.

Correlation coefficient, r is equal to the sum of squares of xy divided by the product of the square root of the sum of squares of xx and xy.

The sample correlation coefficient r measures the strength of the linear relationship and has the following properties:

-1≤r≤1; the closer the value is to −1 or 1, the stronger the linear relationship

– If r is negative, this indicates that as one variable is increasing, the other is decreasing

– If r is positive, this indicates that both variables are increasing or both variables are decreasing

If r = 0, then there is no linear relationship between the two variables

Hey there! :)

Answer:

x = -7/12.

Step-by-step explanation:

Given:

$x + \frac{5}{12} = -\frac{1}{6}$

Create a common denominator for each term:

$\frac{12x}{12} + \frac{5}{12} = -\frac{2}{12}$

Disregard the denominator:

12x + 5 = -2

Subtract 5 from both sides:

12x = -7

Divide both sides by 12:

x = -7/12.
