Answer:
P(defective) = 126/3000 = 0.042
P(not defective) = 1 - P(defective)
= 1 - 0.042 = 0.958
Answer:
Distance to appointment point = 5 miles
Step-by-step explanation:
Let s be the distance to the appointment point,
We have Maria drove to a business appointment at 50mph in the morning.

Answer:
AAA similarity
Step-by-step explanation:
∠A = ∠Q = ∠Y = 50°
∠B = ∠P = ∠Z = 60°
∠C = ∠R = ∠X = 70°
So,
ΔABC ~ ΔQPR
ΔPQR ~ ΔZYX
ΔZYX ~ ΔBAC
It can only be simplified.
x^3-7x^2+2x=-9
