At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 18 m
anyanavicka [17]

Answer:

95% of the customers  have to wait between 10 minutes and 26 minutes

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 18 minutes

Standard Deviation, σ = 4 minute

We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.

Empirical Formula:

  • Almost all the data lies within three standard deviation from the mean for a normally distributed data.
  • About 68% of data lies within one standard deviation from the mean.
  • About 95% of data lies within two standard deviations of the mean.
  • About 99.7% of data lies within three standard deviation of the mean.

Now, we can write:

10 = 18-2(4) = \mu - 2(\sigma)\\26 = 18+2(4) = \mu + 2(\sigma)

Thus, by empirical formula, 95% of the data lies within two standard deviations of the mean.

Thus, 95% of the customers  have to wait between 10 minutes and 26 minutes

You are serving bratwurst and hamburgers at a picnic. You want at least 3 brats or hamburgers for each of your 50 guests. Brats
Greeley [361]
3 x 50 = 150
150 x 1.25 = 187.5
If you were to buy just brats, you would spend $187.50. So, you would have a spare $12.50, which could buy you 8 more.

3 x 50 = 150
150 x 0.95 = 142.5
If you were to buy just hamburgers, you would spend $142.50. So, you would have a spare $57.50, which could buy you 60 more.

PLEASE KNOW BEFORE YOU ANSWER.
barxatty [35]

Answer:

The error is the exponent in the answer should be 11.

Step-by-step explanation:

When you move the decimal place one spot as they do in the final step to move it from a base 10 to a base 1, we have to add a exponent on. Therefore, it should go from 10 to 11.
