Answer:
T
Step-by-step explanation:
The regression line is flat when there is no ability to predict whatsoever. The regression line is sloped at an angle when there is a relationship. The extent to which the regression line is sloped, however, represents the degree to which we are able to predict the y scores with the x scores
8,-4 : 6,-2 : 5,-1 All should add up to four.

Answer:
(- 4, 1 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus

Answer:
9 units²
Step-by-step explanation:
calculate the area of Δ ABC as
area of rectangle - area of 3 outer right triangles
area of rectangle = 5 × 4 = 20 units²
area of left Δ = 
× 3 × 3 = 4 units²
area of Δ on right = × 2 × 4 = 4 units²
area of top Δ = × 5 × 1 = 2 units²
Then
area of Δ ABC = 20 - 4 - 4 - 2 = 20 - 11 = 9 units²
