PLS HURRY WORTH 50 POINTS AND WILL MARK BRAINLIEST A survey of a group of seventh-graders and a group of teachers at a local middle schoolers asked how many siblings they each have. The dot plots below show the results.

students:

What is the closest to the difference between the means?

A. 0.5
B. 1.0
C. 1.5
D. 2.0

the answer is 1.5

Step-by-step explanation:

I took this test

your answer would be b

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
