Question: 1 / 400

What is the mean of the following numbers: 5, 10, 15, 20?

10

15

To find the mean of a set of numbers, you add all the numbers together and then divide the sum by the total count of the numbers.

In this case, the numbers are 5, 10, 15, and 20. First, you add these together:

5 + 10 + 15 + 20 = 50

Next, you determine how many numbers there are in the set, which is 4. Now, you divide the total sum by the number of values:

50 ÷ 4 = 12.5

However, it seems there could be a reconsideration of the numbers or instructions, as the mean value calculated does not match any of the provided answer choices.

The correct approach verifies that the mean of these specific numbers is indeed 12.5, not aligning with the given options. Reviewing the definitions and methods for calculating means is essential for gaining a deeper understanding of statistical measures in this context.
