In set of seven numbers the average of the first four is 15 and the average of the last three is 8 .what is the average of all seven numbers?
To find the average of all seven numbers, we first calculate the total for the first four numbers. Since their average is 15, their total is (4 \times 15 = 60). For the last three numbers, with an average of 8, their total is (3 \times 8 = 24). Therefore, the total of all seven numbers is (60 + 24 = 84), and the average of all seven numbers is ( \frac{84}{7} = 12).
What is the average of 8 12 10 15 7?
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.
What is the average of 16 and 29 and 15?
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.

What is the average of these eight numbers 102.10 249.04 101.02 57.27 46.23 48.12 48.25 43.02?
Since there are 8 numbers, their average is 1/8 of their sum.
What is the average for the following numbers 654924and 15?
Average = (654924 + 15)/2 = 327469.5
What is the average of 14 15 and 16?
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
What is the average of 2 5 and 8?
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.

What is the average of 8 12 10 15 7?
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.
If the average of 15 consecutive numbers is 15 what are the numbers?
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.
What is the average of 16 and 29 and 15?
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.
What is the average for 40 12 -15 -23 and 44?
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.
What is the average of these numbers 5 10 15 and 20?
12.5
How do you find out the average?
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
What is the average of 15 30 45?
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.
