After working for 25 hours, Larry made $375. After working for 40 hours, Kyle made $560. Who is paid the better rate? Explain ho

Juliette [100K]

Answer:

Larry.

Step-by-step explanation:

For Larry, do 375/25 = 15. He is getting paid $15 an hour.

For Kyle, you do 560/40 = 14. He is getting paid $14 an hour.

$15 is greater than $14 an hour, so Larry is getting paid at a better rate.

Clue 1: A black line is shorter than a white line

Katyanochek1 [597]

The black line is shorter than the gray. Let's simplify the rules. (B=Black, W=White, G=Grey

B is less than W which is less than G

That means G is greater than W. B is less than W, which is less than G. Therefore, the black line is not only shorter than the Gray one, but also the shortest out of the three.

I hope this Helps!

he life of light bulbs is distributed normally. The variance of the lifetime is 625 and the mean lifetime of a bulb is 540 hours

almond37 [142]

Using the normal distribution, it is found that there is a 0.877 = 87.7% probability of a bulb lasting for at most 569 hours.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

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

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 540, \sigma = \sqrt{625} = 25$

The probability of a bulb lasting for at most 569 hours is the <u>p-value of Z when X = 569</u>, hence:

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

$Z = \frac{569 - 540}{25}$

Z = 1.16

Z = 1.16 has a p-value of 0.877.

0.877 = 87.7% probability of a bulb lasting for at most 569 hours.
