Aliun [14]

Answer : 0.0129

Step-by-step explanation:

Given : Based on FAA estimates the average age of the fleets of the 10 largest U.S. commercial passenger carriers is \mu=13.4 years and standard deviation is \sigma=1.7 years.

Sample size : n=40

Let X be the random variable that represents the age of fleets.

We assume that the ages of the fleets of the 10 largest U.S. commercial passenger carriers are normally distributed.

For z-score,

z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x=14

z=\dfrac{14-13.4}{\dfrac{1.7}{\sqrt{40}}}\approx2.23

By using the standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be :-

P(x\geq 14)=P(z\geq2.23)\\\\=1-P(z

Hence, the required probability = 0.0129

Which expression is equivalent to 2 (14x-37+28x+12.2-5y-17.5)?
ziro4ka [17]

Answer:

A. 84x - 16y - 10.6

Explanation:

\sf \rightarrow 2(14x-3y+28x+12.2-5y-17.5)

\sf \rightarrow 2 (42x-8y-5.3)

apply distributive method: a(b + c) = ab + ac

\sf \rightarrow 2 (42x) -2(8y)-2(5.3)

\sf \rightarrow 84x -16y-10.6
