For the past two weeks, Kiwa has been recording the number of people surveyed visiting the library at lunchtime. During that time, there were 50 or more people at the library 9 out of 14 days. a What is the experimental probability that there will be 50 or more people at the library during lunchtime on the fiftheenth day?
b What is the experimental probability that there will not be 50 or more people at the library during lunchtime on the fifteenth day?

ask the math teacher she or he would know lol.

step-by-step explanation:

i'm not really sure how to answer that

step-by-step explanation:

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

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.

hope this by jack monhen
