What is the mean of the numbers?

Answer 1

To calculate the mean of the scores, you need to sum all the scores and then divide by the total number of scores.

The scores are: 5, 6, 7, 8, 9, 10.

First, calculate the sum:

\[ 5 + 6 + 7 + 8 + 9 + 10 = 45 \]

Next, count the number of scores:

There are 6 scores.

Now, divide the sum by the number of scores:

\[ \text{Mean} = \frac{45}{6} = 7.5 \]

So, the mean of the numbers is 7.5.
