Using variable concepts, it is found that the explanatory variable is the age.
<h3>Explanatory and response variables:</h3>
- The variables of an experiment are divided into explanatory and response.
- The response variable is the one that is the focus of the study, that is, the one that can be changed.
- The explanatory is the one that explains the reason of the change in the response variable.
In this problem, the <u>age can effect the political party preference</u>, hence:
- The variable that is changed is the political party preference, hence it is the response variable.
- The reason is the age, hence it is the explanatory variable.

Answer:
A(-5,20)
Step-by-step explanation:
A(X,Y)
(X-3)/2=-4 (Y-6)/2=7
X=-5 Y=20
F(x) = 2x + 1
f(3) = 2(3) + 1 = 6 + 1 = 7
g(x) = 3x + 2
g(2) = 3(2) + 2 = 6 + 2 = 8
f(3) ÷ g(2) = ⅞
B is the answer
Hope this helps.
Answer:
(0,0)
Step-by-step explanation:
(x,y)= ( (x1 +x2)/2 , (y1+ y2)/2 )
= ( -7+7/2 , 7-7/2)
= (0/2 , 0/2)
= (0,0)
Therefore, the midpoint is at interval (0,0)
