1/2 of 38 is 19
Add them all up and divide them by 10 which will give you the mean average.
50
3, 4, 5, 6, 7, 8, 9, 10, 11
You add all the data numbers together and divide it by the amount of numbers.(example:10+11+11+13+15=60 60divide by 5=12. 12 is the answer
11
Yes. For example, the average of 9, 10, and 11 is 10. 9 + 10 + 11 = 30 30 / 3 = 10
To find the average of a set of numbers, you add all the numbers together and then divide by the total number of values. In this case, the sum of 8, 9, 10, 11, and 12 is 50. To find the average, you divide 50 by the total number of values, which is 5. Therefore, the average of 8, 9, 10, 11, and 12 is 10.
Add them all up and divide them by 10 which will give you the mean average.
10.8
12. This is because you add the numbers and then divide by the amount of numbers to get an average. So here we add the numbers and divide the total by 3. 10+11+15 = 36. 36/3 = 12.
50
The mean (average) of those numbers is 16.
The numbers are 9, 10 and 11.
Well, darling, if you want to find the average of 6, 9, 10, and 11, you simply add them all up and divide by how many numbers there are. In this case, the total is 36, and since there are 4 numbers, you divide 36 by 4 to get an average of 9. Voilà!
There is not enough information. For example, 2 numbers, whose average is 10 could be -50 and 70 or 10 and 10 or 9 and 11 or 7.5 and 12.5 etc. All that you know in this case is that the sum of the two numbers = average*number of values = 10*2 = 20
lets say these are your numbers 2 4 6 8 10 12 14 16 18 20 add them and you would get 110. Now divide 110 by the amount of numbers you have (10) and your average is 11
3, 4, 5, 6, 7, 8, 9, 10, 11
