Astudent had test score of 85, 72, 63, 91, and 94. find the average of the test scores .

Your answer is 85.

Step-by-step explanation: In order to find out the average you would lay them out like this (least to greatest) : 63, 72 , 85, 91 , 94. Then you'd cross each one evenly.  --, --, 85,-- , --. Remember, if there are two numbers, you'd add them up and divide by two.

Please make sure to correct me if I'm wrong.

Thanks.

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
