The only correct option about the variables is A) The responding variable depends on the manipulated variable.

<h3>How to interpret Statistical variables?</h3>

A manipulated variable is a variable that is changed by the researcher. A manipulated variable is also called an independent variable. A responding variable is a variable that the researcher predicts will change if the manipulated variable changes. A responding variable is also called a dependent variable.

A controlled variable in an experiment is the one that the researcher holds constant or controls. It is also known as a constant or control variable. The controlled variable is not part of an experiment. It is not an independent or dependent variable.

Thus, the only correct option about the variables is option A.

pogonyaev

Answer: 91

Step-by-step explanation:

Given : The number of documentaries = 5

The number of comedies = 7

The number of mysteries = 4

The number of horror films =5

The total number of movies other than comedy = 14

Now, the number of possible combinations of 9 movies can he rent if he wants all 7 comedies is given by :-

^7C_7\times^{14}C_2\\\\\dfrac{7!}{7!(7-7)!}\times\dfrac{14!}{2!(14-2)!}\\\\=(1)\times\dfrac{14\times13}{2}\\\\=91

Therefore, the number of possible combinations of 9 movies can he rent if he wants all 7 comedies is 91 .
