30 points Please help (06.01 MC)
The scatter plot shows the relationship between the test scores of a group of
students and the number of hours they study in a week:

PART A: What is the group of points labeled N called? What is the point labeled M called? Give a possible reason for the presence of point M.

PART B: Describe the association between students test scores and the number of hours they study.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

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.

hope this by jack monhen
