This is the concept of statistics, given that there are 650 students and all of them read a total of 18,996 pages. We are required to get the average number of pages that they all read;
Average, otherwise known as the mean is the calculated 'central' value of a set of numbers;
The formula for mean is given by;
mean=(sum)/(count)
in our case:
sum=18,996
count=650
thus;
mean=18996/650
=29.23
Here we can conclude that the average number of pages read by each student in the High School was 29.23
We can write an equation to represent this problem:
.525x=25.83
Divide by .525
x=49.2
52.5% of 49.2 is 25.83
I think it is 21+10=31...
Answer:
first one, second last one, and last one :)
