Sum = 678
Count = 8
So Average = Sum/Count = 678/8 = 84.75

To be honest pay attention In class
88 + 67 = 155
99 + 99 + 88 + 88 + 72 + 72 = 518
76
88+85 = 173
It is: 9/11 of 88 = 72
Suppose 72 = 88% of x then 72 = (88/100)*x = 0.88x So x = 72/0.88 = 81.8181..
Mean = (88 + 85 + 91)/3 = 264/3 = 88
The median is the average of 85 and 87, that is 86.The median is the average of 85 and 87, that is 86.The median is the average of 85 and 87, that is 86.The median is the average of 85 and 87, that is 86.
