The equation of the inner circle is x2+y2−8x−6y−11=0 and CB = 2. Which statements are correct? Select all that apply.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

d

step-by-step explanation:

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.
