Step-by-step explanation:

The mean absolute deviation is:

MAD = ∑ᵢ₌₁ⁿ│xᵢ − μ│/ n

First, find the mean.

μ = (x + 2x + 3x + 4x) / 4

μ = 2.5x

Now find the mean absolute deviation:

MAD = (│x − 2.5x│+│2x − 2.5x│+│3x − 2.5x│+│4x − 2.5x│) / 4

MAD = (│-1.5x│+│-0.5x│+│0.5x│+│1.5x│) / 4

MAD = (1.5x + 0.5x + 0.5x + 1.5x) / 4

MAD = (4x) / 4

MAD = x

Keith_Richards [23]

2x²-3xy-2y²-2x-11y-12

Write -3xy as a difference

2x²+xy-4xy-2y²-2x-11y-12

write -2x as a difference

2x²+xy-4xy-2y²+4x-6x-11y-12

Write -11y as a difference

2x²+xy-4xy-2y²+4x-6x-8y-3y-12

Factor out 2x from the expression

2x×(x-2y-3)+xy-2y²+4x-8y-3y-12

Factor out y from the expression

2x×(x-2y-3)+y×(x-2y-3)+4x-8y-12

Factor out 4 from the expression

2x×(x-2y-3)+y×(x-2y-3)+4(x-2y-3)

Factor out x-2y-3 from the expression

Answer: (x-2y-3)x(2x+y+4)

Brrunno [24]

16.5 / p = 11 / 18

p = 16.5 × 18 / 11

p = ( 16.5 / 11 ) × 18

p = 1.5 × 18

p = 27
