Jerry walked a dog from 6:40

Mathematics

Lady_Fox [76]3 years ago
8 0

Jerry is paid $6 per hour. He worked 1 hour and 10 minutes.

So, we'll need to find out how much he is paid per minute. We'll divide $6 by 60 minutes; which will give us $0.10 per minute.

For the 10 minutes extra he worked, we'll multiply by $0.10.

10 x 0.10 = 1

This shows that he earned an extra $1 for the additional 10 minutes he worked.

He earned $6 for the full hour plus $1 for the additional 10.

6 + 1 = 7

Therefore, Jerry earned $7.00 for his time worked on that day.

A particular battery claims to have a mean life of 400 hours with a standard deviation of 30 hours. Approximately what percent o
Svetach [21]

Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 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.

In this problem, we have that the mean and the standard deviation are given, respectively, by:

\mu = 400, \sigma = 30.

The proportion of the batteries will last more than 420 hours is <u>one subtracted by the p-value of Z when X = 420</u>, hence:

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

Z = \frac{420 - 400}{30}

Z = 0.67

Z = 0.67 has a p-value of 0.7486.

1 - 0.7486 = 0.2514.

0.2514 = 25.14% of the batteries will last more than 420 hours.
