The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

Assume the data is:

This means that the number of schools is 4

So:

The average of the assumed data is 1238

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
