right 3 units down 5 units
right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.
Then convert the vertex form into standard form for the equation in the choice.
Thus, the answer is B.
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 .
