The water depth in a harbor rises and falls over time. The function f(t) = 4.1 sine (StartFraction pi Over 6 EndFraction t minus StartFraction pi over 3 EndFraction) + 19.7 models the water depth, in feet, after t hours. During the first 24 hours, at what times does the water depth reach a maximum?
at 5 and 17 hours
at 11 and 23 hours
at 2, 8, 14, and 20 hours
at 5, 11, 17, and 23 hours

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

the eight graders whould be the answer
