Answer:
158,254.08 ft²
Step-by-step explanation:
A nonagon is a polygon with 9 sides and 9 angles. A regular nonagon has all equal sides and all equal angles. In order to find the area of a nonagon, you can use the formula:
A = where 'a' represents the length of one side
Calculating the known measurements ahead of time, we get a condensed, or simplified formula:
A = 6.1818 x a²
Using the side length of 160 ft:
A = 6.1818 x 160² = 158,254.08 ft²
The 99% confidence interval for the difference between the average years of service between men and women would be = 3.43.
<h3>What is confidence intervals?</h3>Confidence interval is defined as the statistical parameter that is used to know if a set of values would fall within a certain range of population or not.
Using the statistical table, the value of 99% or 0.99 confidence interval has a z-score = 2.576
The standard error that exists between the bothe value = SD/Ö
Where SD = difference between the standard deviations = 8.39 - 4.39 = 4
Where ñ = different between the average years of service = 9.62
Standard error= 4/√9.62 = 4/3.01 = 1.33
The confidence interval = 2.576 × 1.33 = 3.43.
