The number of miles Cynthia travels each day isshown. What are the values of the measures of center and variability that bestdescribe the data set?57, 40, 35, 60, 56, 57, 59 a. The mean is 52 miles and the interquartile rangeabout 8 miles b. The median is 57 miles and the interquartile range19 miles c. The mean is 57 miles and the interquartile range 19miles d. The median is 52 miles and the interquartile rangeabout 8 miles

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

graph of this function as shown below:

each side has a different length.
