mean represent in terms of the question?

Answer 1

The mean is 4.5

Explanation:

The mean represents the average. To find the average of the data you're given you add all the numbers in the data set that you're given and divide by the number of elements in that data set.

For example:

`0+1+2+3+4+5+6+7+8+9=45`

Now we divide by the number of elements in this set, which is 10, so:

`(45)/(10) = 4.5`
