The mean is the average. If the mean of 4 letter (a,b,cd) is 12, the sum of them would be 12x4 =48

Now add e to the total: 48 + 50 = 98

The mean is the total divided by the quantity:

Mean = 98 /5 = 19.6

<h3>What is an average?</h3>

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Given that the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.

The average is calculated by dividing the sum of the total number of items by the total counts of the items.

Average = 14400 / 2400

Average = 6

Therefore, the number of books taken by each student is 6.
