Answer:

2.3

Step-by-step explanation:

n = Number of data points = 9

The data set is

4, 7, 5, 8, 12, 2, 3, 5, 7

Mean

\bar{x}=\dfrac{4+7+5+8+12+2+3+5+7}{9}=5.89

Absolute mean deviation

\dfrac{|4-5.89|+|7-5.89|+|5-5.89|+|8-5.89|+|12-5.89|}{9}\\+\dfrac{|2-5.89|+|3-5.89|+|5-5.89|+|7-5.89|}{9}=2.3

The mean absolute deviation of the data set is 2.3.

The slope of the line below is -3. Which of the following is the point-slope form of the line?​
Jobisdone [24]

Answer:

A. y+6 = -3(x-2)

Step-by-step explanation:

The slope point formula is:

y - y₁ = m (x - x₁)

Our slope is negative 3, and our coordinates given are 2 and -6.

Substitute -3 for m, -6 for y₁, and 2 for x₁

y - (-6) = -3 (x - 2)

Negative and negative multiplied together make postive

A. y+6 = -3 (x-2)
