abercrombie & Fitch is having a sale. The sign posted in the store says, "everything is marked down 65%." Scott buys a jacke
nikdorinn [45]

a) We have that the discount is 65 %

Scott buys a jacket for $150

First, we will calculate the discount

150\times\frac{65}{100}=97.5

then we need to subtract the quantity calculated above from the original price

150-97.5=52.5

After the markdown Scott paid $52.5

b.

In order to know the taxes first, we need to calculate the 5% of $52.5

52.5\times\frac{5}{100}=2.625

then we will sum the 5% plus the price after the markdown

52.5+2.625=55.125

The total cost of the jacket is $55.125

The SAT mathematics scores in the state of Florida for this year are approximately normally distributed with a mean of 500 and a
Greeley [361]
<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.
