Answer:
-1.5 or -1 1/2
Step-by-step explanation:
I can only guess what is actually asked for. a lot of things went wrong when copying this problem description in here.
the basic question I understand is to solve the equation of
4(n + 10) = 34
=>
n + 10 = 34/4 = 8.5 or 8 1/2
n = 8.5 - 10 = -1.5 or -1 1/2
Mean is basically average
basically find how many terms (there are 6 terms)
then add them all together
5+-11+7+12+-1+0 =12
then divide the sum by the number of terms
12 divided by 6=12/6=2
the answer is 2 or B
