Suppose you are doing a study on a population of 195 iguanas at a zoo. you take a random sample of 20 iguanas. which would not be a characteristic of the sample group? a) the age of the sample group of iguanas. b) the weight of the sample group of iguanas. c) the length of the sample group of iguanas. d) the total number iguanas at the zoo.

D) The total number of iguanas at the zoo. This was already stated in the question.

Step-by-step explanation:

b

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
