So you add all of the numbers of books owned by each student then divide it by 8, after you get the result you subtract the total by the number of books of each student individually (and if you get a negative it will be positive) then after you finish subtracting all 8 students book total you add up the numbers together and then you divide by 8 again and you get your mean.. hope this helped

A) To find the mean you have to add all of the values together and divide it by the total number of values. So, 8+9+9+7+8+6+9+8=64 ---> there are 8 numbers----> 64/8=8----> the mean is 8.
(B) Take each number and subtract it by the mean. For example 7-8= -1. Then take the absolute value of that number. For example. l7-8l= 1. Do that for every number. Add the differences together. 0+1+1+1+0+2+1+0=6. Divide the sum by the number of values added. 6/8= .75  This is the mean absolute value deviation.

A fruit company delivers its fruit in two types of boxes: large and small. a delivery of 5 large boxes and 3 small boxes has a t
Hoochie [10]
Let's let the weight of a large box be L, and the weight of a small box be S.

We know that 5 large boxes and 3 small boxes is 120kg, so:
5L + 3S = 120

We also know that 7 large boxes and 9 small boxes is 234kg, so:
7L + 9S = 234

You can multiply the first equation by 3 to get:
15L + 9S = 360

See how now both equations have 9S? We can now subtract one from the other:
(15L+9S) - (7L+9S) = 360-234
8L = 126
L = 15.75

Now sub this value back into an equation:
(5x15.75) + 3S = 120
3S = 41.25
S = 13.75

Double check these values
(7x15.75) + (9x13.75)
= 110.25 + 123.75
=234, which is consistent with above.

So a large box is 15.75kg, and a small box is 13.75kg.

Hope this helped
