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
The mean average of the given numbers 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.
9, 10, 10, 10, and 11, which also happens to have a mode of 10, as well as a mean of 10.
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
