Susan took 6 minutes on a quiz, Tom took 8 minutes on the same quiz, Mary took 9 minutes, Al took 12 minutes, and Eric did not finish the quiz. Find the mean, median, and mode.

(What would Erics number be for this equation?)

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

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

hd extra 3-7 x d en is the answer
