Which statements describe a residual plot for a line of best fit that is a good model for a scatterplot? Check all that apply.
kondaur [170]

Answer: The true statements are:-

There are about the same number of points above the x-axis as below it.

The points are randomly scattered with no clear pattern.

The number of points is equal to those in the scatter plot.

Explanation:

  • A residual plot is a graph which shows that the residuals on the vertical axis and the independent variable on the horizontal axis.

Thus, the number of points is equal to those in the scatter plot and ame number of points above the x-axis as below it.

We know the points are randomly scattered across the plot, so that there is no relationship.  Thus the points are randomly scattered with no clear pattern.

PLEASE NO LINKS DONT WASTE YOUR TIME IM NOT GONNA CLICK. Use the graph of the polynomial function to find the factored form of t
USPshnik [31]

Answer:

B.

Step-by-step explanation:

factored form actually contains the x intercepts right in it. Basically whatever sets the whole equation equal to zero.

On the graph you can see that it passes through both positive and negative 4. so (x+4)(x-4) is the answer because plugging in 4 for x will make it zero. Same for plugging in negative 4

Hope this helps!

Inga [223]

Original Picture:

Width: 15 cm

Length: 16 cm

Enlarged Picture:

Width: unknown

Length: 48 cm

The new length is 48 cm, and the original length is 16 cm.

How many times larger is the new length than the old length?

We divide 48 by 16 to get 48/16 = 3

The new length is 3 times larger than the original length.

This means that the new width will also be 3 times the original width.

Original width: 15 cm

New width: 3 * 15 cm = 45 cm

Answer: 45 cm

Hope It would Help you
