Answer:

-4

Step-by-step explanation:

In the Whisker-Box plot, the Lower Quartile can be found by the end of the left side of the box. In this case, it is directly above the -4, and so is your answer.

Answer:

-4

Step-by-step explanation:

The edges of the box are the lower quartile, the median, and the upper quartile (going from left to right)

We want to find the value of the lower quartile

That is the left side of the box, -4

!! Need help with the problem in the photo. !!
lianna [129]

Answer:

B 3x-2y=10

Step-by-step explanation:

This is correct because when solved it has the same slope as line <em>k.</em>

The slope of <em>k</em> is 3/2.

3x-2y=10

first subtract 3x from both sides

-2y=-3x+10

next divide both sides by -2

y=3/2x-5

this shows that the slope 3/2 is the same as line <em>k</em>

Find angle D if angle B = 50
Mariana [72]
<h3>Answer:  80 degrees</h3>

============================================================

Explanation:

I'm assuming that segments AD and CD are tangents to the circle.

We'll need to add a point E at the center of the circle. Inscribed angle ABC subtends the minor arc AC, and this minor arc has the central angle AEC.

By the inscribed angle theorem, inscribed angle ABC = 50 doubles to 2*50 = 100 which is the measure of arc AC and also central angle AEC.

----------------------------

Focus on quadrilateral DAEC. In other words, ignore point B and any segments connected to this point.

Since AD and CD are tangents, this makes the radii EA and EC to be perpendicular to the tangent segments. So angles A and C are 90 degrees each for quadrilateral DAEC.

We just found angle AEC = 100 at the conclusion of the last section. So this is angle E of quadrilateral DAEC.

---------------------------

Here's what we have so far for quadrilateral DAEC

  • angle A = 90
  • angle E = 100
  • angle C = 90
  • angle D = unknown

Now we'll use the idea that all four angles of any quadrilateral always add to 360 degrees

A+E+C+D = 360

90+100+90+D = 360

D+280 = 360

D = 360-280

D = 80

Or a shortcut you can take is to realize that angles E and D are supplementary

E+D = 180

100+D = 180

D = 180-100

D = 80

This only works if AD and CD are tangents.

Side note: you can use the hypotenuse leg (HL) theorem to prove that triangle EAD is congruent to triangle ECD; consequently it means that AD = CD.
