15 and -3
To find the average or mean - Add all the numbers together and divide by the amount of numbers you added: So 16 + 29 + 15 = 60 (1) (2) (3) <- So 3 numbers added together 60 / 3 = 20. So the average of 16, 29, and 15 is 20.
The pair of numbers are 15 and 2, or -2 and -15 15 - 2 = 13 15 x 2 = 30 -2 - (-15) = -2 + 15 = 13 (-2)(-15) = 30
15 + 16 1 x 31 41 - 10 62/2
15
2 and 13
They are -3 and -5
-13
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.
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.
8, 5 and 2
2*3*-5 = -30 3*-5 = -15 -5 - 5 - 3 - 2 = -15
Average= All of your numbers added together divided by how many numbers you have. 13+17=30 30/2=15
