Below are the heights of the players on the University of Maryland women's basketball team for the 2018-2019 season and the heights of the players on the women's field hockey team for the 2019 season. dot plot of field hockey and basketball player heights

The mean height of the basketball players is 72.5 inches. Using the mean of 72.5, what is the Mean Absolute Deviation of the basketball players' heights?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
