Which measure will rita calculate how much the electricity bills vary, on average, from the mean billed amount? the monthly bills were: $92, $98, $90, $99, $96, $91, $89, $106, $95, $102, $96, $99. a. interquartile range b. range c. median d. mean absolute deviation

c

Step-by-step explanation:

because to find the average is to add all your numbers up and to divide them by how many numbers you have

and the median is the finding the middle which is the average you line them up from lowest to greatest value and cross one off from the beginning and one from the end until you are left either one or two values

its d. the mean

Step-by-step explanation:

its right on plato

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
