Pythagorean theorem(√82)^2 = 9^2 + x^2
x = 1 cm
15^2 = 9^2 + y^2
y = 12 cm.
12-1 = 11
Area = 9*11 = 99 cm^2
Answer:
<em>The answer to your question would be D.</em>
<em>D. Range: 20</em>
<em>Mean: 10</em>
<em>Median: 9</em>
<em>Mode: none</em>
Step-by-step explanation:
1, 2, 3, 8, 9, 12, 14, 20, 21
Range: 21 - 1 = 20
Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10
Median: 9
Mode: there are no mode in the following given data set.
Answer: $183.71
<u>Step-by-step explanation:</u>
Original amount is $5,175.00
1st year: Increase of 9%
→ $5175(1 + 0.09)
= $5175(1.09)
= $5640.75
2nd year: Decrease of 5%
→ $5640.75(1 - 0.05)
= $5640.75(0.95)
= $5358.71
Gain: 2nd year - Original
→ $5358.71 - $5175.00
= $183.71
