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.

Let's denote the ages of the birds as x1, x2, x3, x4, x5, and x6. We know that the average age is 10, so the sum of their ages is 6 * 10 = 60. Since the difference between the youngest and oldest is 8, we have the equation x6 - x1 = 8. Additionally, the sum of their ages is x1 + x2 + x3 + x4 + x5 + x6 = 60. With these two equations, you can solve for the ages of the 6 birds.
