Answer:
1 = 115°
2 = 115°
3 = 65°
Step-by-step explanation:
P=65, so S (3) =65
360-65-65=230
230/2=115
Q (1) = 115
R (2) = 115
First you need to set up your decimal as a fraction
45 9
---- divided by 5 ------
100 20
9/20 is your answer
Answer:
A) The equation for circumference is C=2piR. So Filling in for circle A we have 28.26=2*pi*4.5 so we want to isolate pi which I'm gonna call x for it's easier for me xD. So we're gonna start by dividing 4.5 from each side which is gonna leave us with 6.28=2*x which gives you x(pi)= 3.14. For circle B we have 15.70=2*x*2.5 isolate x by first dividing 2.5 which leaves us again with 6.28=2x and x= 3.14.
B) The equation for area is A=piR^2. So again for circle A we have 63.585=x9^2. This one is harder but also are you sure that the area is 63.585 it's supposed to be 254.469 (We'll come back to this)
C) The observation you can make about the value of pi for circles A and B is that it stays consistent at 3.14
hoped i helped : )

Answer:

Step-by-step explanation:
- <em>Take into account that a population data set contains all members of the group and a sample data set contains only a subpart of the group.</em>
<em />
- <em>In this case, Ms. Smith can take the scores of all students of the math class, due to this group is not enough big to consider to take a subpart.</em>
<em />
<u><em>Hence, Ms. Smith should consider her data as a population data set.</em></u>
