Answer 2

Answer:

One method is to calculate the arithmetic mean. To do this, add up all the values and divide the sum by the number of values. For example, if there are a set of “n” numbers, add the numbers together for example: a + b + c + d and so on. Then divide the sum by “n”.

The Arithmetic Mean

The simplest formula for a mean is the following: Add up all the numbers you want to average, and then divide by the number of items you just added. For example, if you want to average 10, 20, and 27, first add them together to get 10+20+27= 57.
