Answer 2

The sum is 95.

Given

There are 5 numbers.

The mean is 19.

To Find

We need to find the sum.

Solution

The mean of a set of numbers is the average value of those numbers.

The mean is equal to the sum of all the data values divided by the count of values in the data set.

Mean = Sum / Count

19 = $\frac{sum}{5}$

sum = 19 × 5

       = 95

Hence the sum is 95
