Answer:
243,000 people
Step-by-step explanation:
First, what we need to do is to calculate the area of the region using the 5-mile radius
Mathematically, we can calculate this as the area of a circle
Area = pi * r^2
Our r here is 5 miles
Area = pi * 5^2 = pi * 25 = 78.54 square miles
Now to get the population, we know that per square mile we have 3,100.
Hence per 78.54 square mile, we have 78.54 * 3100 = 243,273 people
To the nearest thousand, 243,000
Answer: 72%
Step-by-step explanation: Well, we want to know what percent 608 is of 845, so to solve that, let's call 845 100%, as we're solving it terms of 845. 845 is 100%, then it follows that 8.45 is 1%.
Now we can see how many 8.45's go into 608, which comes out to 71.95266...%, which can be rounded nicely to 72%
Answer: There are 45 combinations.
Step-by-step explanation:
If the order in which you watch the episodes does not matter, then we can use the combinatory defined as:
If we have N elements, and we want to make groups of K elements, we have
combinations.
In this case, we have a total of N = 10 episodes, and we want to make groups of K = 2.
Then we have:
There are 45 combinations.
