An elevator has a placard stating that the maximum capacity is lb passengers.​ So, adult male passengers can have a mean weight of up to If the elevator is loaded with adult male​ passengers, find the probability that it is overloaded because they have a mean weight greater than lb.​ (Assume that weights of males are normally distributed with a mean of and a standard deviation of ​.) Does this elevator appear to be​ safe?

b.

step-by-step explanation:

i just know

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
