Given:Population, P = 210,000 peopleRadius, r = 12 milesSolving for population density, D, per square mile, first solve for Area, A:A = π(R^2)A = 3.1416(12^2)A = 3.1416(144)A = 452.3893 square milesD = P/AD = 210,000/452.3893Population density, D = 464.2019 people per square mile
C) average of a data set
You add all of the data and divide by the number of data
The correct answer is slope = 1
Answer:
The area of the triangle is 75 cm²
Step-by-step explanation:
![area \: a = \frac{1}{2} base \times height \\ a = \frac{1}{2} bh](https://tex.z-dn.net/?f=area%20%5C%3A%20a%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20base%20%5Ctimes%20height%20%5C%5C%20a%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20bh)
![a = \frac{bh}{2} \\ a = \frac{10cm \times 15cm}{2} = \frac{150 {cm}^{2} }{2} \\ area \: = 75 {cm}^{2}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bbh%7D%7B2%7D%20%5C%5C%20a%20%3D%20%20%5Cfrac%7B10cm%20%5Ctimes%2015cm%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B150%20%7Bcm%7D%5E%7B2%7D%20%7D%7B2%7D%20%20%20%5C%5C%20area%20%5C%3A%20%20%3D%2075%20%7Bcm%7D%5E%7B2%7D%20)
