Answer:
The z-scores of both the mean and the median are zero.
Step-by-step explanation:
In a normal distribution, the mean and median values will be the same, in this case, 100. Therefore, both the mean and median will have the same score.
The z-score is given by:

For X = 100:

The z-scores of both the mean and the median are zero.
Answer:
n=1
Step-by-step explanation:
distribute
-6 times -8n is =48n
-6 times 6 =-36
8 times -4 = -32
8 times n =8n
rewrite equation
48n-36+-32+8n=-12
48n+8n-36-32=-12
56n-68=-12
add 68 on both sides
=56
56n=56
n= 1
