In response to the increasing weight of airline passengers, the Federal Aviation Administration (FAA) in 2003 told airlines to a
aleksandr82 [10.1K]

Answer:

There is a 33.72% probability that the total weight of the passengers exceeds 4500 pounds.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

There are 22 passengers. Passengers average 190 pounds in the summer, including clothing and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. This means that \mu = 22*190 = 4180, \sigma = 22*35 = 770.

What is the approximate probability that the total weight of the passengers exceeds 4500 pounds?

This probability is 1 subtracted by the pvalue of Z when X = 4500. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{4500 - 4180}{770}

Z = 0.42

Z = 0.42 has a pvalue of 0.6628.

This means that there is a 1-0.6628 = 0.3372 = 33.72% probability that the total weight of the passengers exceeds 4500 pounds.

What is the Distance between (-3,-11) and (8,-42)
OlgaM077 [116]

Answer:

d = 32.893

Step-by-step explanation:

The distance formula is

d = \sqrt{(x2-x1)^{2}  + (y2-y1)^{2}

now we plug in the x and y

d = \sqrt{(8-(-3))^2 + ((-42) - (-11))^2}

d = 32.893

What is a counterexample for the conjecture? Any number that is divisible by four is also divisible by eight
Cloud [144]
The value 12 is a good counterexample. It is divisible by 4 (since 12/4 = 3 is a whole number with no remainders or decimal portions) but 12 is not divisible by 8 (note how 12/8 = 1 remainder 4 = 1.5)

To find other examples, add 8 to 12 to get 20. Then add on 8 more to get 28. This pattern continues on forever.
