Answer:
232cm^2
Step-by-step explanation:
Formula A= 1/2ap
1/2 (8)(58) = 232
I got 65 by 360 /5 sides=72
72/2=36
Tan 36×8= 5.8 ×10 small triangles =58

Step-by-step explanation:
ANSWER:
Whenever p is not the same as 0.5
(Whenever p is different from 0.5)
Step-by-step Explanation:
Recall that the sample size needed will be at it's maximum when p is equal to 0.5.
Therefore, if p is equal to 0.5, i.e p=0.5 The sample size formula will yield the required sample size but whenever p is different from 0.5, using p=0.5 The sample size formula will yield a sample size larger than required to construct a confidence interval for p with a specified bound and a specified confidence level.
When you see this kind of question use « BODMAS »
1.Add the 2 digits which is 3+7=10
2.Add the digits inside which is 0.7+1.3=2
3.Add the inside and outside
3+7(0.7+1.3)
10(2)=20
500,000 *(1 + x) = 600,000
we're going to solve for x
first divide both sides by 500,000
1 + x = 1.2
subtract 1 from both sides
x = 0.2
turn that into a percent by multiplying it by 100
0.2*100 = 20%
the magazine sales increased by 20%
