Suppose weights of the checked baggage of airline passengers follow a nearly normal distribution with mean 46 pounds and standar

Alik [6]

Answer:

85.99% of airline passengers incur this fee.

Step-by-step explanation:

When the distribution is normal, we use 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.

Mean 46 pounds and standard deviation 3.7 pounds.

This means that $\mu = 46, \sigma = 3.7$

Most airlines charge a fee for baggage that weigh in excess of 50 pounds. Determine what percent of airline passengers incur this fee.

As a proportion, this is 1 subtracted by the pvalue of Z when X = 50. So

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

$Z = \frac{50 - 46}{3.7}$

$Z = 1.08$

$Z = 1.08$ has a pvalue of 0.8599

0.8599*100% = 85.99%

85.99% of airline passengers incur this fee.

HELP ITS MAKING ME DO ANOTHER ONE

Anna007 [38]

Answer:

Since we know that each of the three triplets are the same age we can put next to n, 3.

And given that another child is 14 years old we can put that next to the "+" sign.

In total, it would equal 32, so put the 32 after the equal sign.

It should look like this:

3n + 14 = 32

But now they want us to solve for the triplet's ages, so we just solve for n;

3n + 14 = 32

-14 -14

3n = 18

/3 /3

n = 6, the triplet's ages are 6 years old each.

Rachel can make 3 bracelets in an hour. Oliver can make only 2 bracelets in an hour, but he already has completed 5 bracelets. E

Sidana [21]

For the answer to the question above, Since Rachel makes 3 bracelets an hour, her linear equation should be y=3h. 3 represents the rate of change and h represents the number of hours as a variable.
Oliver's linear equation is y=2h+5 because 2 is the rate of change and 5 is the b value or the y-intercept in a linear equation y=mx+b. To find when both have the same number of bracelets, we find the point of intersection...
2h+5=3h
5=3h-2h
5=h
Therefore in 5 hours, both will have the same amount of bracelets.
