Answer 1

Answer:

✒5 is the correct answer to it.

➡The mean is a type of average. It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. ... Then divide the sum by how many values there are. So if you have five values, add them all together, then divide the result by five. That is the mean.
