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.

Sandra saves 7% of her salary for retirement. This year her salary was $2,000 more than her salary than in the previous year, an
Effectus [21]

9514 1404 393

Answer:

  • 2,000
  • $45,000

Step-by-step explanation:

Where x represents the previous year's salary, its amount this year is said to be ...

  x + 2000

The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:

  0.07(x +2000) = 3290

__

Solving for x, we find ...

  x = (3290/0.07) -2000 = 45000

Sandra's salary the previous year was $45,000.
