Which statement best describes the association between variable x and variable y?

a. perfect negative association

b. perfect positive association

c. moderate negative association

d. moderate positive association

Option: A is the correct answer.

A. Perfect negative association.

Step-by-step explanation:

A perfect association in a scatter plot is one in which we get a line of best fit such that all the points could lie on that line or we can say that the points have a linear association.

Also a negative association is one in which there is a  increase in one variable  while decrease in the other.

So, here in the scatter plot we could clearly observe that with the increase in the Variable X the other variable i.e. Variable Y is decreasing.

Hence, Option: A is the correct answer.

A. perfect negative association

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
