Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² = 7² + 4² = 49 + 16 = 65 ( take the square root of both sides )
AB = \sqrt{65} → D
The percent of the original price after markup is 98%
<h3>Mark up and discounts</h3>
Given the following parameters
- Original price of tablet = $460
If during a sale, a store offered a 15% discount on a tablet, the new price after discount will be:
New price = 0.85 * 460
If the tablet computer was marked up by 15% after the discount, then the price after the markup is given as:
- Price after markup = 1.15 * 391
Price after markup = $450
To get the required percent;
x% of 460 = 450
x% = 450/460
x% = 0.978
x = 98%
Hence the percent of the original price after markup is 98%

Answer:
$2160
Step-by-step explanation:
Here we are going to use our simple interest formula. We know that p=2000,t=1, and r=8/100=0.08 Once again, lets replace those values in our formula: A=2000(1+(0.08)(1)) A=$2160
The empirical rule says that roughly 99.7% of the population is within 3 standard deviations of the mean.
Start at the center 60 which is the mean. Add on 3 standard deviations
60 + 3*4.5 = 73.5
and subtract off 3 standard deviations from the mean
60 - 3*4.5 = 46.5
So roughly 99.7% of the population of cattle has horn lengths between 46.5 inches and 73.5 inches
<h3>Answer: Choice D. 46.5 in - 73.5 in</h3>
