A residual plot shows how far away each point in the scatter plot is from the least squares regression line.
MariettaO [177]

Answer:

Scatter plot one is not a good fit so answer is first picture to the left  in a top row( see the pattern). Second plot is a good fit so the answer is the last right picture in a top row( points around x axis).

Step-by-step explanation:

A random scatter of points in the residual plot indicates that the linear function is a good fit for the given data. A non random residual plot  indicates that the chosen function is not a good fit.

Please guys help me please
lbvjy [14]

Answer:

C' = (2,8)

A' = (4,4)

T' =(10,10)

Step-by-step explanation:

Given

k =2

C =(1,4)

A = (2,2)

T =(5,5)

Solving (a): The new points

To do this, we simply multiply the old points by the scale factor.

i.e.

New = Old * k

So:

C' = (1,4) * 2 = (2,8)

A' = (2,2) * 2 = (4,4)

T' = (5,5) * 2 = (10,10)

Solving (b): The graph of the original image
