The first 10 composites are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18.

18. The first ten composite numbers are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18
They are 6, 10, 14, 15, 21, 22.They are 6, 10, 14, 15, 21, 22.They are 6, 10, 14, 15, 21, 22.They are 6, 10, 14, 15, 21, 22.
6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.
Mean = Average of all numbers5 + 14 + 7 + 4 + 12 + 6 + 14 + 6 + 18 + 12 = 9898/10 = 9.8Mean = 9.8
The average is 10.
4, 6, 8, 9, 10, 12, 14, 15, 16, 18 The average is 11.2
(14 + 6) ÷ 2 = 10 Therefore, the mean (average) is 10.

If the average of 6 birds' age is 10, and the difference in the youngest and oldest is 8 years, the ages of the 6 birds are 6, 10, 12, 17, 18, and 14.
