Question

What is the mean of -0.05, 0.09, -0.04,-0.08

Answer 1

-0.02

Explanation:

To find the mean (average) of a set of numbers, you add up all the numbers and then divide by the total count of numbers. In this case, you have four numbers: -0.05, 0.09, -0.04, and -0.08.

Mean = (Sum of the numbers) / (Total count of numbers)

Mean = (-0.05 + 0.09 - 0.04 - 0.08) / 4

Now, calculate the sum of these numbers:

Mean = (-0.05 + 0.09 - 0.04 - 0.08) = -0.08

Now, divide the sum by the total count of numbers, which is 4:

Mean = -0.08 / 4 = -0.02

So, the mean of the numbers -0.05, 0.09, -0.04, and -0.08 is -0.02.
