1) Here is a distribution of 20 observations, sorted from smallest to largest:
1,3,3,5, 8, 12, 15, 16, 18, 21, 24, 26, 26, 28, 31, 33, 34, 35, 40, 41
The mean of the distribution is 21. What is the sum of all the distances
from the mean?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%
