The average of the numbers 8, 12, 10, 15 and 7 is 10.4. To work this out, just add up the numbers in the list and divide them by the amount of numbers in the list.
To find the average or mean - Add all the numbers together and divide by the amount of numbers you added: So 16 + 29 + 15 = 60 (1) (2) (3) <- So 3 numbers added together 60 / 3 = 20. So the average of 16, 29, and 15 is 20.
12.5
Since there are 8 numbers, their average is 1/8 of their sum.
The first eight composite numbers are 4, 6, 8, 9, 10, 12, 14, and 15.
Average = (654924 + 15)/2 = 327469.5
Average can be solved by adding all of the numbers and dividing by the total number of items being added. So:14 + 15 + 16 = 45 / 3 numbers = 15
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.

The average of the numbers 8, 12, 10, 15 and 7 is 10.4. To work this out, just add up the numbers in the list and divide them by the amount of numbers in the list.
The numbers are 8 to 22 (inclusive).It immediately springs to mind that if 15 is the average then the numbers will start at 15 - 7 (8) and finish at 15 + 7 (22), but let's prove this!We know that 15 is the average of 15 numbers. We can therefore work out what the 15 consecutive numbers add up to. We can then use algebra to calculate these numbers.The numbers total 15 * 15 = 225Therefore, where x is equal to the lowest number in the series:x + (x+1) + (x+2) + (x+3)...etc all the way up to + (x+14) = 225Therefore:15x + 105 = 22515x = 225 - 10515x = 120x = 8.
To find the average or mean - Add all the numbers together and divide by the amount of numbers you added: So 16 + 29 + 15 = 60 (1) (2) (3) <- So 3 numbers added together 60 / 3 = 20. So the average of 16, 29, and 15 is 20.
To find average, you add all the numbers together, then divide the answer by how many numbers you have, (in this case, you have 5 numbers). 40 + 12+ (-15) + (-23) + 44 = 58; 58 / 5 = 11.6. The average is 11.6.

Add up all the numbers and divide that total by the number of numbers. 1+ 2 + 3 + 4 + 5 = 15 15/5 = 3 The average is 3
Since there are 8 numbers, their average is 1/8 of their sum.
To find the average of a set of numbers, you add up all the numbers and then divide by the total count of numbers. In this case, the sum of 15, 30, and 45 is 90. Since there are three numbers in the set, you divide 90 by 3 to get an average of 30.
