Calculate the average (arithmetic mean) of the list of numbers shown in the table. (rounded to the nearest tenth)
goblinko [34]

Hello!

<h3><u><em>Answer</em></u></h3>

The mean of the numbers shown in the table is C. 50.5

<h3>__________________________________________________</h3><h3><em><u>Explanation</u></em></h3>

To calculate the mean, simply add up all the numbers and divide by the amount of numbers there are in the list.

18 + 55 + 101 + 96 + 55 + 18 + 22 + 23 + 22 + 57 + 88 = 555

There are 11 numbers in the table, so we divide by that.

555 / 11 = 50.45...

Finally, round to the nearest tenth: 50.5
