Question

The mean of the following numbers 2.3,
2.1, 0.75, 0.25, 2.8, 0.9, 15, and 15 is____

Answer 1

To find the mean of a set of numbers, you add up all the numbers and then divide by the total number of numbers.

Adding up the numbers: 2.3 + 2.1 + 0.75 + 0.25 + 2.8 + 0.9 + 15 + 15 = 39.1

Counting the total number of numbers: 8

Dividing the sum of the numbers by the total number of numbers: 39.1 / 8 = 4.8875

So, the mean of the given numbers is 4.8875.
