Use the 68-95-99.7 rule to solve the problem. Scores on a test are normally distributed with a mean of 106 and a standard deviation of 20. What percentage of scores are greater than 126?

d

step-by-step explanation:

d

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
