Step-by-step explanation: To find the mean time add all the times and divide by the amount of times you have, which is 9.
0 + 15 + 30 + 90 + 105 + 120 + 45 + 60 + 75 = 540 total minutes spent.
Now divide 540 by 9 to get the mean time. 540 divided by 9 = 60.
So the mean is 60 minutes, not 75 minutes.

Answer:
f(2) = -2
Step-by-step explanation:
plug in 2 to wherever x is in this statement:
f(2) = -2(2^2) - 2(2) + 10
f(2) = -2(4) - 4 + 10
f(2) = -8 - 4 + 10
f(2) = -2
