Answer:

D. Both distributions are skewed left, so the interquartile range is the best measure to compare variability.

Step-by-step explanation:

Plotting the data roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.

In such a scenario, interquartile range is normally the best measure to compare variations of data.

Therefore, the last option is the best for the data provided.

please mark me brainliest :)

NikAS [45]

Answer:

$T = -17\,^{\textdegree}C$

Step-by-step explanation:

The temperature at 7:00 pm is:

$T = 7\,^{\textdegree}C + \left(-6\,\frac{^{\textdegree}C}{h} \right)\cdot (4\,h)$

$T = -17\,^{\textdegree}C$

Find the Area of the shaded part.

Westkost [7]

To find the area of the shaded part we have to subtract the rectangle area from the triangle area :

$s = \frac{1}{2} \times (8x + 2)(6x) - (x)(3x + 1) \\$

$s = \frac{1}{2} \times (48 {x}^{2} + 12x) - (3 {x}^{2} + x) \\$

$s = \frac{48}{2} {x}^{2} + \frac{12}{2} x - 3 {x}^{2} - x \\$

$s = 24 {x}^{2} + 6x - 3 {x}^{2} - x$

$s = 24 {x}^{2} - 3 {x}^{2} + 6x - x$

$s = 21 {x}^{2} + 5x$

And we're done

Have a great day ♡

All I want is to find the X.<br>Tell me how to start this problem<br>please and thank you ❤️

Blababa [14]

Answer:

x = 7

Step-by-step explanation:

We know that adding TUW and WUV will give TUV.

So you can substitute the given equations for each and form a lengthy equation

5x + 3 + 10x -5 = 17x - 16

Move all the variables to one side, and the constants to the other

5x + 10x - 17x = -16 - 3 + 5

Simplify!

-2x = -14

x = 7
