How many composite numbers are between 1 and 21?
12 numbers (including 21). The numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21.
what is the mean of 26 23 23 22 21 20 18 15?
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.
What is the mean of 21 17 14 28 15?
Add all of the numbers, and divide the result by how many numbers there are.21 + 17 + 14 + 28 + 15 = 9595 / 5 = 19
What are 5 numbers with a mean of 16 a median of 15 a mode of 21 and a range of 11?
To create a set of five numbers that meets these criteria, we can use the numbers 21, 21, 15, 14, and 10. The mean is ( \frac{21 + 21 + 15 + 14 + 10}{5} = 16 ), the median is 15 (the middle number when arranged in order), the mode is 21 (the most frequently occurring number), and the range is ( 21 - 10 = 11). Thus, this set satisfies all the given conditions.
Why are 9-15-21 not Prime numbers?
ANSWER: 9, 15, 21 are not prime numbers because these numbers have factors other than 1 and themselves. Therefore, 9, 15, 21 are composite numbersFactors of 9 other 1 and itself (9) : 3Factors of 15 other 1 and itself (15): 3, 5Factors of 21 other 1 and itself (21): 3, 7

How do you find the mean of a group of numbers?
you add all of the numbers in the group together and then divide the number you get by how many numbers are in the group EX: your group is 21, 32, 12, 15. you add 21+32+12+15= 80. then you divide 80 by 4 because you have four numbers in your group. so your mean is 20!
What are 6 two diget numbers that have the mean of 20?
15, 17, 19, 21, 23, 25
What are 5 numbers with a mean of twenty and a median of twenty one?
15, 16, 21, 23, 25
Are 15 and 21 square numbers?
No
Smaller of two triangular numbers whose sum and difference are also triangular numbers?
The answer would be 15 and 21. The triangular numbers are 1,3,6,10,15,21,28,36,45,55,66,78. 15 plus 21 is 36 which is on the list. 21 minus 15 is 6 and that is on the list as well.
