Answer:
c = 
250
Step-by-step explanation:
To solve this problem, let us first assign some variables.
Let us say that:
d = represents the population density of the circular region
(in units of 513 people per square mile)
p = represents the population of the circular region (in
units of people)
r = is the radius of the circular region
Now we can see that if we divide p by d, we can get a value
which has a units of square mile. Thus the area of the region, hence:
Area = 79,000 people / (513 people per square mile)
Area = 154 square mile
The area of a circle has the formula:
Area = π r^2
Therefore calculating for r:
154 square mile = π r^2
r = 7 miles (ANSWER)
I would say "None of these" but I'm probably wrong.
Answer:
<em>B. Statistical analysis is applied to the results of the study.</em>
<em>B</em><em> </em><em>and </em><em>C.</em>
2. If Greg drove 135miles in 3 hours, we must divide the number of miles by the number of hours to determine how many miles per hour he traveled:
135/3= 45mph
3. If she is payed $45 for 5 hours, we must divide the amount of money by the number of hours to find how much money she made per hour:
45/5= 9 dollars per hour
4. if she payed $0.72 for 8 ounces of water, we must divide the cost by the number of ounces to find out how much they spent per ounce:
.72/8= .09 dollars per ounce or 9 cents
1. The answer will be less than one. We know this because a positive number that is multiplied by a negative number will always equal a negative number and therefore be less than one.
