I also don't think you can see the graph. Sorry. I'll show another way.
XZ=ZY and XZ+ZY=XY, which means X,Y, and Z form a degenerate triangle. (I don't know if you have learned it yet. Sorry if you haven't.) Since from Y to Z, we go 2 steps left and 14 steps down, we do the same to arrive at X=(-1-2,-7-14) which is (-3,-21). So, X=-24. I hope you understood. I am very sorry for the damage I have made on this website. I will not use it again, so I will not break your rules.
I think it's B, but we can have a debate.
Okay, let's narrow this down:
First, read the problem carefully.
Now, we eliminate.
Choice D is wrong since it reflects of the whole U.S., not New Jersey.
Choice C is wrong since it reflects on STUDENTS at this public university in New Jersey.
Now we are down to A and B.
To me, I think it's B since it has a larger sample size, and it will have more accurate results.
I don't know why, either. I got B.
A triangle has 180 degrees. A straight angle has 180 degrees.
The straight line is 6x. Also, a triangle has 180. So, x=30.
(I don't know your level, so I don't know how to explain it. I don't think you have learned too much about triangles yet, so I'm super sorry if you don't get my explanation.)
If DG is at most 1, we can draw a circle with radius 1 and center D.
We know the circle and triangle will share a 60 degree sector.
So the area of the sector is pi/6.
The area of the entire equilateral triangle is sqrt3/4*a^2, and since a=3, 9sqrt3/4.
3.8971 is the approximate area of the triangle, and 0.5236 is the approximate area of the sector.
So 0.5236/3.8971 which is around 0.134356
