+1982 {1, 1, 1, 1, 1, 1, 1, 1, 1, n}
The mean of this set of numbers is 10. What is the value of n?
A) 1
B) 9
C) 11
D) 19
E) 91
+129852 [ 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + n]
___________________________________ = 10
10
Multiply both sides by 10 an simplify
9 + n = 100 subtract 9 from both sides
n = 91
