To find the average of a data set take the sum of the numbers and divide that by the number of data points in the set.
In practice, this means doing:
(44+28+18)/3=30. 30 is the average.
28
The least common multiple of the numbers 18 and 28 is 252.
Use the definition of "average", as follows.Add all the numbers up. Call the result "sum". Then count how many numbers there are, and divide "sum" by that number. In this particular case, the interval between any two consecutive numbers is the same (an arithmetic sequence); in this case, you can use the following shortcut: the average is simply the number in the middle. (And if there are an even number of numbers, take the average between the two numbers in the middle.)
It would be 28 as there are 4 numbers before it and 4 numbers after it. Also if you arrange them from lowest to highest: 12, 16, 18, 24, 28, 31, 32, 32, 32 then also 28 is at middle.
30
The Answer is 26

18
10 + 18 = 28 10 x 18 = 180
28
28 composite
2 :)x This is how you can work it out: 18: 1,2,3,6,9,18 (These are the numbers that 18 and 28 go into.) 28: 1,2,4,7,14,28 So the highest common factor of 18 and 28 is 2. Hope it helps :)

With a score of 24 out of 28, you miss only one in 7 on average, or 14.3%. You have a success rate of 85.7%.
This is an okay score. The average score for anyone is about 100. Good scores are 130+.
The range of these numbers, the difference between the highest and lowest of these numbers, is equal to 28-15 = 13.
