Answer:
8 gallons were eaten.
Step-by-step explanation:
You would multiply the percentage by the amount of gallons. So 80% would be 0.8 so it would be 0.8 multiplied by 10 which gives you 8.
He will be charged for 551 miles.
30283-29582=701 miles traveled in the rental vehicle.
150 of those miles are free; 701-150 = 551 miles he will be charged for.

<u></u><u>The correct answer is 47.5%, or 0.475.</u>
Explanation:
The empirical rule states that in any normal distribution:
68% of data will fall within 1 standard deviation of the mean;
95% of data will fall within 2 standard deviations of the mean; and
99.7% of data will fall within 3 standard deviations of the mean.
The mean is 500 and the standard deviation is 100. This means that 700 is 2 standard deviations away from the mean:
(700-500)/100=200/100=2.
We know that 95% of data will fall within 2 standard deviations from the mean. However, included in the 95% is data less than the mean and greater than the mean. Since we are only concerned with the scores from 500 to 700, we only want the half that is greater than the mean:
95/2 = 47.5%, or 0.475.
