Answer:
It should just be the radius
Step-by-step explanation:
The radius is half the diameter of the circle and all you’re doing is taking the radius multiple times
Answer:
- 1205 people per square miles
Step-by-step explanation:
- Population = 10 511 215
- Area = 8 723 square miles
<u>Population density is the number of people per unit of area:</u>
- 10511215 / 8 723 = 1205 people per square miles
Answer: Multiply the number(s) outside the parenthesis by the numbers inside the parenthesis. The distributive property is expressed in math terms as the following equation: a(b + c) = ab + ac.
Step-by-step explanation:
2(3 + 4) - 12 Multiply 2 times 3 first.
2 x 3 = 6.
Then multiply 2 times 4.
2 x 4 = 8.
Remember our equation earlier? a(b + c) = ab + ac.
In this case, 2 is a, 3 is b, and 4 is c.
So 2[a](3[b]+4[c]) = 2[a](3)[b] + 2[a](4)[b].
Let's rewrite this in a way that can be read better.
2(3+4) - 12 = 2(3) + 2(4) - 12.
2(3+4) - 12 = 6 + 8 - 12.
2(3+4) - 12 = 14 - 12.
2(3+4) - 12 = 2.
Hope this helped! :)
Answer:
Mean of resulting data = 7 times mean of original data=7a
Step-by-step explanation:
Given that all values in a data set are multiplied by 7. to find the mean of the new set.
Let {x1,x2....xn} be the original data set.
The mean of this data set a= 
Now multiply all values by 7
New data set
= {7x1, 7x2...7xn}
Sum of these = 7(x1+x2+..+xn) = 7 times sum of original data set
No of element = n for both the sets
Hence new mean = 7 * mean of original set.=7a
in other words, if the mean of the values in a data set is a. If each of the values in the data set were multiplied by 7, new mean would be 7a.
