The sample mean is the sum of the sample values divided by the number of them:
(7 +7 +10 +6 +9 +6 +8 +7.5 +8.5 +8)/10 = 77/10 = 7.7
The sample mean is 7.7.
Answer:
x = -9
Step-by-step explanation:
4x+10=-26
Subtract 10 from each side
4x+10-10=-26-10
4x = -36
Divide each side by 4
4x/4 = -36/4
x = -9
