to find the mean, you add all the numbers together then divide by how many numbers there are. so the mean for 4 8 18 21 22 23 is 16
balls
To find the mean of the numbers, first sum them up: 18 + 15 + 21 + 10 + 24 + 21 + 18 + 16 + 20 + 22 + 18 + 18 + 12 + 21 + 25 + 20 + 19 + 23 = 346. Then, divide this total by the number of values, which is 18. Thus, the mean is 346 ÷ 18 ≈ 19.22.
22
To calculate the mean you add all of the numbers together, and then divide by how many numbers were added. In this case, the mean is 21.
17, 18, 19, 21, 22, and 23
21.8Simply add them all up, and then divide by how many numbers you have.
All the numbers are composite except the ones in bold: 18 19 20 21 22 23 24 25.
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
mean = the sum of 23, 19, 26, 17, 21, 24, 22 divided by 7 = 152/7 =21.71
