12. a) Suppose 4 of the 22 tagged bucks are randomly chosen for a behaviour study.
What is the probability that
i) all four bucks have the cross-hatched
antlers?
ii) at least one buck has cross-hatched
antlers?
b) If two of the seven cross-hatched males

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:

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors

answer: the answer for that is 22/3
