Pi • radius squared = Area
n = pi
n • 3 • 3 (3 squared is the same thing as 3 multiplied by 3)
9n
Therefore, your answer would be 9n m2
When building a Venn Diagram, I always start from the area with the most overlap to the areas of least overlap. Once you have placed the 3 in the middle, you have counted those people, and therefore you must subtract them from the other surveys. Example: since there are 3 people that like all three subjects, now only have 5 students that like just math and English instead of 8.
Therefore:
A) 36 Students were in the survey
*Add all the numbers within the Venn diagram up. Overlapping doesn't matter because no one is double counted.
B) 6 People liked only Math
*Can't touch any other circle but Math
C) 20 Students liked English and math, but not history
*You add 9+5+6, since these bubbles are not overlapping with history.
I Hope this helps and let me know if you have any further questions!
Answer:
Relative frequencies
First row
0.8125 ,0.1875 ,16
Second row
0.555 ,0.444 ,9
third row
18 , 7 , 25
Step-by-step explanation:
Given data
allowance No allowance total
Chores 13 3 16
<u>No chores 5 4 9</u>
<u>Total 18 7 25</u>
<u><em>Relative frequencies</em></u>

Answer:
Number of students(n1)= 4,402
Step-by-step explanation:
Giving the following information:
Number of students= 4,512
Declining rate= 2.5%
<u>To calculate the number of students next year, we need to use the following formula:</u>
Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)
x= number of years
Number of students(n1)= 4,512/1.025
Number of students(n1)= 4,402
The factors of 48 are 1,2,3,4,6,8,12,16,24, and 48. Take factors of 4, and see which of them are not on that list.
