Answer: A. 0.50
Step-by-step explanation:
The formula to find the sample size : 
, where p= Prior estimate of population proportion.
E= Margin of error
z* =Critical z-value.
When , we do not have prior estimate of population proportion , we use p= 0.5 because at p=0.5 it gives the maximum same sample size for the corresponding confidence interval and margin of error.
Therefore , the conservative value for n can be obtained by using p=0.50.
Therefore , the correct answer is A.0.50 .
First plug in -4 for g to get 3(-4)-1. 3(-4) equals -12, and -12-1 equals -13.
Answer:
ya you can take it both like integer and decimal
cause - the negative mark make it negative the . make it decimal
we must do the following:
0
1
2
3
4
5
6
7
8
9
select the major, the minor and the half and add, like this:
therefore:
also:
the groups are:
(9,0,1,5); (7,6,2); (8,4,3)
Answer:
No
Step-by-step explanation:
Each ratio is irreducible, and they are different. Hence they are not the same value, so cannot be a proportion. A proportion is two equal ratios.
5 : 3 = 40 : 24
13 : 8 = 39 : 24 . . . . not the same as 40 : 24
_____
<em>Examples of proportions</em>
5/3 = 40/24 . . . is a proportion
13/8 = 39/24 . . . is a proportion
