The correct
answer is-164
4z - ( - 3 z)
= 4 z + 3 z = 7 z
Answer:
76
Step-by-step explanation:
median is the number in the very center of the list of numbers in order:
64, 72, 72, 80, 85, 89
to find the one in the middle we take away the numbers from both ends:
72, 72, 80, 85
72, 80
since there are two numbers in the middle we’ll find the average
(72+80)/2
152/2
76
Slope of Side EF- 3
Slope of Side FG- 2/-6
Slope of Side GH- 3
Slope of Side HE- 2/6
Since approximately 68% of a (roughly) normal distribution falls within one standard deviation of the mean, that leaves 32% that falls outside, and by symmetry 16% should lie above one standard deviation of the mean.
