At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 20 minutes and a standard deviation of 5 minutes. Using the empirical rule, what percentage of customers have to wait between 5 minutes and 35 minutes?

About 99.7% of the population wait between 5 minutes and 35 minutes.

Step-by-step explanation:

According to the Empirical rule,

If a population is normally distributed, then

About 99.7% of the population lies within 3 standard deviations from the mean.

Here, Population is normally distributed with Mean = 20 minutes , standard deviation = 5 minutes

By empirical rule,

About 99.7% of the population wait between (20-3(5)) minutes and (20+3(5)) minutes.

About 99.7% of the population wait between 5 minutes and 35 minutes.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
