Answer:
The 95% confidence interval for the true proportion would be given by (0.570;0.630)
.
And if we convert this into % we got (57.0%, 63.0%)
Step-by-step explanation:
The information given we have the following info given:
represent the sampel size
represent the sample proportion of interest
The confidence level is 95%, our significance level would be given by 
and 
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
Replacing the info given we got:
The 95% confidence interval for the true proportion would be given by (0.570;0.630)
.
And if we convert this into % we got (57.0%, 63.0%)
Answer:
the domain will be all real #'s bc the arrows are continuous/never ending. The range would be y<u><</u>4 because the line starts at 4 and goes down.

Answer:
a = 
Step-by-step explanation:
Given
ai + bj and 5i - 2j are perpendicular and b = 3, that is
ai + 3j and 5i - 2j are perpendicular, then
The scalar product = 0 , that is
5a - 6 = 0 ( add 6 to both sides )
5a = 6 ( divide both sides by 5 )
a =
