Answer 1

Ok, so:

We know that the grades are the following:

95, 100, 70, 80.

1. If we want to calculate the average in his music class grades, we have to sum all the dates before, and then divide the result by the amount of dates.

This is:

Average = ( 95 + 100 + 70 + 80 ) / 4

Average = 345 / 4

Average = 86.25

2. The total is (95 + 100 + 70 + 80), and this is 345

3. We can see that, in data set, there are 4 numbers.
