Find the mean
Answer Details
To find the mean of a set of numbers, you need to add up all the numbers and then divide by the total number of numbers. In this case, we have 11 numbers:
12, 47, 49, 15, 43, 41, 13, 39, 43, 41, 36
To find the mean, we add up all these numbers:
12 + 47 + 49 + 15 + 43 + 41 + 13 + 39 + 43 + 41 + 36 = 379
Then we divide by the total number of numbers, which is 11:
379 ÷ 11 = 34.45
Therefore, the mean of the set is 34.45.
