A sample of n=8 scores has a mean of m=12. What is the value of ∑x for this sample
Answer: We are given the mean of 8 scores is 12.
We are required to find the sum of these 8 observation's, 
We know that:

We are given:




Hence, sum of 8 observation's, 
The answer is 27 hope it helps
Answer:
C
Step-by-step explanation:
f(x) = |x|: f(0) = 0, f(1) = 1, f(-1) = 1
f(x) + 5 = |x| --> f(x) = |x| - 5: f(0) = -5, f(1) = -4 f(-1) = -4
Therefore it shifts down by 5
The smallest y-value is -3 when x=0
[-3,∞)
