Final answer:

To round the mean of 9, 9, 11, and 5 to the nearest ten, you calculate the mean (8.5) and then apply rounding rules. Since the digit after 8 is 5, it rounds up to 10.

Step-by-step explanation:

You've asked about rounding a set of numbers to the nearest ten. When rounding numbers, we follow specific rules depending on the value of the digit. All digits are significant in providing a round figure. In our case, we must compute the mean of 9, 9, 11, and 5 before rounding it.

  1. First, we add all numbers together: 9 + 9 + 11 + 5 = 34.
  2. Then we divide the sum by the number of values, which is 4 in this case: 34 / 4 = 8.5.
  3. Since we need to round to the nearest ten, we look at the digit in the tens place, which is 0. 8.5 rounded to the nearest ten is 10 because the digit after 8 is 5, which rounds the 8 up to a 9, and since there is no digit in the tens place, it remains 0, turning into 10.

The result is that the mean of these numbers, rounded to the nearest ten, is 10.
