Answer:
Step-by-step explanation:
7259.75 - 7100 = 159.75
he earned 159.75 in interest
159.75/ 7100= .0225
and if you convert that to percentages then its 2.25%
Formula:
Minimum = first element of set
First Quartile = (n+1)/4
Median = (n+1)/2
Third Quartile = 3(n+1)/4
Maximum = Last element of set.
Solution:<span>
The five number summary of ( 90, 85, 97, 76, 89, 58, 82, 102, 70, and 67) is,
Minimum = 58
First Quartile = 70
Median: = 83.5
Third Quartile = 90
Maximum = 102</span>
First step: Find how wide the bulletin board is
15 ft² ÷ 3 ft = 5 ft
Step the second: Use the perimeter formula P = 2l + 2w
P = 2(5) + 2(3)
<u>P = 16 ft</u>
A % is out of a hundred, so you don't need the %/100. Then, you wouldn't do cross multiplication, you would just divide 15/27. Remember, it would be 15/27 because it's percent markup, not the percent the price increased by. So, doing that simple calculation on a calculator you get 0.5555. This converted to a percent is just moving the decimal to the right twice, or multiplied by a 100. That would give you 55.55%, and that's your answer. Make sense?
