Answer:
3.64 Km.
Step-by-step explanation:
Given,
Total population = 20,000 people
Population density = 480 people per square kilometer
Area of the circle town
![A = \dfrac{20000}{480}](https://tex.z-dn.net/?f=A%20%3D%20%5Cdfrac%7B20000%7D%7B480%7D)
![A = 41.667\ km^2](https://tex.z-dn.net/?f=A%20%3D%2041.667%5C%20km%5E2)
Radius of the circle town
![\pi r^2 = 41.667](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%20%3D%2041.667)
![r = 3.64\ km](https://tex.z-dn.net/?f=r%20%3D%203.64%5C%20km)
Hence, the radius of circle town is equal to 3.64 Km.
<u>Answer:</u>
The Ranking Percentile is (B) 97.5%
<u>Explanation
:</u>
To find the percentile rank we need to find the z- score. After finding the z-score match this value with the corresponding value in z-score table.
Formula to find the z-score
Z-score=![\frac{\text { scored obtained - mean }(\mu)}{\text { standard deviation }(\sigma)}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%20%7B%20scored%20obtained%20-%20mean%20%7D%28%5Cmu%29%7D%7B%5Ctext%20%7B%20standard%20deviation%20%7D%28%5Csigma%29%7D)
Substituting the values in the above equation, we find
Z-score=
=2
So, the Z-score is +2
Now, the corresponding value of Z-score 2 in the table is 0.9772
or the percentile score is 97.72 ~ 97.5
.
Depends on if you want it rounded.
