What is the mean absolute deviation

3,5,8,1,4

Mean absolute deviation: 1.84.

Step-by-step explanation:

How do you find the mean absolute deviation for a bunch of numbers?

What's the mean of those numbers?

(3 + 5 + 8 + 1 + 4) / 5 = 4.2.

Absolute difference:

What's the average of those absolute differences?

(1.2 + 0.8 + 3.8 + 3.2 + 0.2) / 5 = 1.84. That's the mean absolute deviation of those five numbers.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
