An environmental organization is trying to determine the proportion, p, of working adults living in high-density urban areas that regularly use public transportation for their daily commutes. they will collect a sample of n working adults in high-density urban areas and compute the sample proportion, pb, to estimate p. how large does n have to be so that pb is within 1% of the true value with at least 75% probability?

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

the answer is 1030 it's very simple math.
