Answer:
Correct option: A. Weight.
Step-by-step explanation:
In regression analysis there are two kinds of variables: Explanatory and Response variable.
The explanatory variable are used to predict the changes in the response variable. They are also known as independent or predictor variable.
The response variable are observed for any changes caused by the explanatory variable. They are also known as the dependent or experimental variable.
In this case it is provided that heavier cars have lower fuel efficiencies.
It implies that there is linear inverse relationship between the variables weight of the car and fuel efficiency.
The response variable is the fuel efficiency and the explanatory variable is the weight of the car. Since the weight of the car is used to determine the fuel efficiency.
Thus, the explanatory variable is the weight of the car.

Answer:
56 bags of a chocolate and a popsicle
Step-by-step explanation:
The first thing is to find the relationship between the number of popsicles and the number of chocolates, which would be the quotient of these:
100/56 = 1.78
Since it does not reach number two, you cannot add 2 popsicles and 2 chocolates, therefore the only way that they contain the same amount is that there is a chocolate and a popsicle, that is to say that a total of 56 bags would come out.
36 clowns and zebras..
if there are twice as many zebras as clowns then divide the amount by 2
36/2 = 18 so..
now there are 18 zebras and 18 clowns but we want twice as many zebras..
so by process of elimination we can figure out that
there are 24 zebras and 12 clowns which = 36
the answer is 24 zebras Connor counted
