10
They are 15, 16, 17, 18 & 19.
19. It is prime.
The composite numbers between 11 and 19 are 12, 14, 15, 16 and 18
15
22
To find the mean of the numbers 15, 18, and 24, you first add them together: 15 + 18 + 24 = 57. Then, divide the sum by the number of values, which is 3: 57 ÷ 3 = 19. Therefore, the mean of the numbers is 19.
They are: 12, 14, 15, 16 and 18
The composite numbers between 11 and 19 are: 12 14 15 16 18 The other numbers, 11, 13, 17, and 19, are all prime.
To find the mean of the set (15, 22, 19, 20, 29, 18, 25, 19, 31), first sum the numbers: (15 + 22 + 19 + 20 + 29 + 18 + 25 + 19 + 31 = 208). There are 9 numbers in the set, so the mean is ( \frac{208}{9} \approx 23.11). Thus, the mean of the set is approximately (23.11).
the answer is 30 its the sum of all these numbers then divide by 2
All of the numbers appear once and as a mode is the most commonly occurring number, there is no mode.
12, 14, 15, 16, and 18 are composite numbers 11, 13, 17, and 19 are prime numbers
