Below are the scatter plot and residual plot for a set of data.
Vsevolod [243]

Answer:

A linear model (is/is not) the best fit for the data because the residual plot (shows no pattern/shows a pattern) and is (scattered/not scattered).

Step-by-step explanation:

A linear model should be used when you want to view the data as a continuous response. This means that when the data is increasing/describing then the line should be in a uniform pattern.

If you were to look at the residual plot, you can see that the points curve in a pattern, meaning that the point is not scattered which is not good criteria for a residual plot.

Mentioned before, the points on the residual plot are in a pattern, so it’s not scattered as well.

Find the value of x. Round to the nearest tenth.
STALIN [3.7K]

Answer:

x = 10.2

Step-by-step explanation:

To find x, use Cosine

Cosine = \frac{adjacent}{hypothenuse}

⇒ Cosine 22 = \frac{x}{11}

Cosine of 22 is 0.93

⇒ 0.93 =  \frac{x}{11}

Multiply 11 on both sides:

⇒ 0.93 x 11 = \frac{x}{11} x 11

⇒ 10.23

Round to the nearest tenth:

10.23 ⇒ 10.2

x = 10.2

Which shows two triangles that are congruent by aas?
Serga [27]

Answer:

(A) shows two triangles that are congruent by AAS. AAS (Angle-Angle-Side) postulate states that if two angles and the non-included side one triangle are equal to the two angles and the non-included side of the another triangle, then the two triangles are said to be congruent.
