Answer:
99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 18 minutes
Standard Deviation, σ = 4 minutes
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.
Thus, 99.7% of the customers have to wait:

Thus, 99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
You would need 13/14 12in rulers to make it the size of the flag
Probably 2561 but since area equal r^2 I thought it would be 3217
Add all the Braves score. Add all the Giant score. Then, you take the Giant's score and subtract it with the Braves score. :)
Answer:
20 Tshirts
Step-by-step explanation:
Tshirts = $7.90 each
Shipping = $2
Total amount = $160
Amount of tshirts bought = y
7.90y + 2 = 160
7.90y = 160 -2
7.90y = 158
Divide both sides by 7.9
y = 158÷7.9
y = 20
