girls in the high school. Which of the following is a representative sample of the high school population?

A.Sample 4: 7 boys and 6 girls

B.Sample 1: 10 boys and 10 girl

C.Sample 2: 10 boys and 35 girls

D.Sample 3: 6 boys and 7 girls

problem:

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

f(5/2) = 10/3

i hope this !
