Answer:
The 90% confidence interval for the proportion of all homeowners in the United States that hold a home equity loan is (0.176, 0.224)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval for the proportion of all homeowners in the United States that hold a home equity loan is (0.176, 0.224)
Answer: To find the volume, you multiply length times width times height:

Answer:
Step-by-step explanation:
Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is
240 + 25/100 × 240 = 240 + 60 = 300
To determine the price tag of 40% discount and that would still ensure that she makes £300,
Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as
x - (40/100 × x) = x - 0.4x = 0.6x
So 0.6x = 300
x = 300/0.6 = 500
So the price tag will be £500
