Hey!
It looks like we are talking about finding the mean. First, let's write the numbers.
[tex]22.10, 13.45, 25.10, 17.20, 19.10[/tex]
We have five numbers. To find the mean, we have to add all those numbers and divide the result by 5.
[tex] \frac{22.10+ 13.45+ 25.10+ 17.20+ 19.10}{5} [/tex]
Simplify
[tex]Mean=19.39[/tex]
We have successfully determined that the average (mean) of this set of values is 19.39.
Thanks!
