Answer:

14 dvd cases

5 envelopes

Step-by-step explanation:

We need to find the least common multiple of 5 and 14

Find the prime factors

5 = 5*1

14 = 2*7

Multiple them together

2*5*7 = 70

The least common multiple is 70

70/5 = 14 so we need to buy 14 dvd cases

70/14 = 5 so we need to buy 5 envelopes

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
