Question

What is the mean of 75,14,48,81,39,67,33,19

Answer 1

Mean = 47

Explanation:

Given terms :

• 75
• 14
• 48
• 81
• 39
• 67
• 33
• 19

The mean is equal to the sum of the terms divided by the number of terms.

Therefore, the mean is equal to :

• 75 + 14 + 48 + 81 + 39 + 67 + 33 + 19 / 8 [Take terms that add up to 100, makes it easier to calculate!]
• 100 + 100 + 89 + 87 / 8
• 200 + 176 / 8
• 376/8
• Mean = 47

Answer 2

47

Explanation:

To find the mean, you sum all the numbers, then count the number of numbers you summed up (amount of numbers in the array which in this case is 8) and then divide the two. So you get

Σarray/arraysize = 75+14+48... / 8
