Why is the average if a number?
The average of a set of numbers is the sum of all the numbers, divided the amount of numbers in the sequence. For example, the average of 12, 14, 13, 15, and 20, would be the sum of the numbers, 74, divided by the amount of numbers in the sequence, 5. So the average is 74/5, which is 14.8.
Is an average of a set of numbers the same as the average of the averages of the subsets of numbers?
No, it is not. Example: the average of (5 and 7) is 6, and the average of (50, 60 and 70) is 60, but if we add all five numbers we have 192, so the overall average is 192 divided by 5 = 38.4 and the reason for that is we have more and bigger numbers in the second set.
How do you work out the avarge in maths?
The average is the sum of all of the numbers in a data set DIVIDED by the number of numbers in the data set. Therefore, given the following set of numbers 5 5 7 8 10 The average would be (5 + 5 + 7 + 8 + 10) / 5 which will give you 7. so the average is 7
What is the average score?
to find the average you would add all the numbers then divide by how many numbers there are. so for example the average of 2,3,4,5,6 would equal 2+3+4+5+6=20 then you would divide by 5 because there are 5 numbers so in the example the answer would be 20/5=4
How can you form a program of finding the average of five numbers?
to find the average (a.k.a mean) of any set of numbers you add all of the numbers up, then divide by however many numbers there are. for ex: 2,7,5,9,4 1st step: 2+7+5+9+2= 25 2nd step: 25 divided by 5= 5 average equals=5
