Evaluate the piecewise function for f(8)

A)-16
B)-4
C)4
D)23

-4

Step-by-step explanation:

f(x)=-1/2 x,if x>2

f(8)=-1/2 \times 8=-4

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
