Answer:

Step-by-step explanation:

The interquartile range is the difference between the values of the upper quartile and the lower quartile.

The upper quartile is the value at the right side of the box, that is 36

The lower quartile is the value at the left side of the box, that is 16

Interquartile range = 36 - 16 = 20

Help please 4, 5, 6.......

Assoli18 [71]

4. Supplementary angles together make a straight line (two right angles). So BOE is supplementary to BOC

Answer: ∠BOE

5. Distance and midpoint between (4,-2), (6,8)

$d = \sqrt{ (6-4)^2 + (8 - -2)^2} = \sqrt{2^2+10^2}=\sqrt{104}=2 \sqrt{26}$

midpoint

$\left(\dfrac{4 + 6}{2}, \dfrac{-2 + 8}{2} \right) = (5, 3)$

Answer: distance 2√26, midpoint (5, 3)

6.That's a rectangle oriented parallel to the axes, width parallel to the x axis of 7 - -3 = 10 and length along y of 1 - - 4 = 5, so an area of 10(5)=50

Determine the measure of ∠Y. images attached

Gwar [14]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Y

To find the value of ∠Y we use tan

We have

$\tan(∠Y) = \frac{25}{20} \\ \tan(∠Y) = \frac{5}{4} \\ ∠Y = { \tan^{ - 1} } \frac{5}{4} \\ ∠Y = 51.34019...$

We have the final answer as

Hope this helps you

HELP IMMEDIATELY!! ATTACHMENT<br>I'm not sure on how to find the y intercept please help! thanks

Yuliya22 [10]

well if you can find the slope then choose one of your ordered pair and plug them in tot he corresponding variable. since you don't know what the y intercept you basically find x which will be the y int.
