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
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

20 + 21 + 22 + 23 + 25 + 27 + 30 + 30 = 198/8 = 24.75
The mean = The sum of all the values ÷ The number of values. 18 + 15 + 22 + 18 + 25 + 19 + 23 = 140 : Number of values = 7 Mean = 140 ÷ 7 = 20
