Use the binomial probability formula to find the probability of more than 5 success (k = 6 & k=7) in 7 trials (n=7) given the probability of success is 0.40.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.

the answer is d.x= 90°

y= 50°

arc lm= 100°
