20: 1, 2, 4, 5, 10, 20 30: 1, 2, 3, 5, 6, 10, 15, 30
There are infinitely many groups of 20 numbers that have a mean of 25. One example: 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35
Out of that group, only 30
20 and 30 15 and 60
20
You add up all of the numbers. Then you divide by the amount of numbers you added. Another way to say find the mean is to find the average. Ex 20+10=30 30/2=15
30
20 and 30 4 and 15
The mean of the numbers is 22. The median of the numbers is 21. The mode is 16, 20 and 30 or you can say the set has no mode.
It is 30 because 2*3*5 = 30
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 10: 10, 20, 30 15: 15, 30 The LCM of 10 and 15 is 30.
20: 1, 2, 4, 5, 10, 20 30: 1, 2, 3, 5, 6, 10, 15, 30
5, 10, 15, 20, 25, 30
Out of that group, only 30
