PLZ HELP WILL MARK THE BRAINLIEST IF ANSWER IS CORRECT!!!

C

Step-by-step explanation:

If you want to survey 100% of the students, and 20% has been already surveyed, 200 students would chose pop as their favorite genre of music because 41 x 5 = 205, which is closest to 200.

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!
