Step-by-step explanation:
IQR is the difference between the upper and lower medians so the IQR = 7 - 4 = 3
Answer:
This is a educated guess, but x is 80 and y is 100.
Step-by-step explanation:
My logic here is that the triangles are the same because of all the congruent lines and stuff. But from there, you know that both the right and the left side are 40 degrees. You know the total degree of a triangle is 180 so 180 - 40 - 40 is 100. So the final angle is 100. If you look at x, its on the outside, but on a line. If you can imagine a circle, its half, so its a 180 degrees total. Then its 180 = x + 100. So x is 80. And then by that same logic its y = 100.
Answer:
4/12 or 1/3
Step-by-step explanation:
there is a fraction of 4 hours in the 12 hours, so 4/12.
That can be simplified to 1/3.
The equation is y = -2/3x + 6
