Sheryl got these scores on her spelling tests.
95, 89, 99, 85, 82
what is the mean absolute deviation of her spelling test scores?
(10 point)
pl
5.6
17.0
89
90

d? maybe

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
