5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.
???
32
13 and 2
The two numbers are -2 and -15
To find the number that is in the exact middle of two numbers, add the numbers and divide by 2.25 + 15 = 40. 40 divided by 2 = 20.26.9 is one of infinitely many values between 27 and 15.
Mode is the average. You have to add all the numbers together, and then divide by how many numbers there are. Example: Add: 1+2+3+3+6= 15 then Divide: 15/5=3. Three is your mode.
To find the mean, you add all of the numbers and divide by how many numbers you added together. 7+2+3+2+1=15. 15/5=3. The mean is 3.
Infinitely many. If you restrict yourself to positive numbers only, but allow repetitions, then there are 15. If you disallow repetitions, only 2.
you add the numbers together than divide that by 2, after that you add how many numbers there are then subtract 2
The numbers are 11 and 4
-5 and +3
