Answer:
48
Step-by-step explanation:
So what you are trying to do here is to find the mean.
The means just means the average or norm.
To find the mean, you first add up all the numbers on the table to find a total.
So then you divide the total that you have by the numbers of values that you added together which may sound confusing but let me show you so it will make more sense.
So to find the number of values that you added together, you just count the student - A, B, C, D ,E or 49, 47 , 46, 45, 53. You just count the numbers that you have there in total which is again, 5.
Anyways since the total of the numbers when added up is 240 you just divide that by 5.
So when you do that your answer should be 48.
