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.

Mkey [24]

Answer:

x=0.3

Step-by-step explanation:

divide 8 by both sides to isolate x

8x/8= 2.4/8

2.4/8= 0.3, leaving x by itself, giving us x=0.3

!HELP! SHOW WORK PLEASE SO I CAN UDNERSTAND!

Nata [24]

Ok.

The volume of a cone is the volume of a cylinder over 3.

The volume of a cone is:
$\frac{1}{3} \pi r^{2}h$

This problem gives us the diameter, which is twice of the radius. So, we'll just half it.
Radius (me) = 4 cm.

Substitute our given values into the equation.
$\frac{1}{3} \pi (4)^{2}h \ or \ \frac{1}{3} \pi (4)^{2}(10) \ or \ \frac{1}{3} \pi (16)(10)$

Multiply
$\frac{1}{3} \pi(160) \ or \ \frac{1}{3} (3.14)(160) \ or \ 1.047(160)$

Multiply
$167.52 \ cm^{3}$

This would make $167 \ cm^{3}$ the closest option.
