Answer:
The percent is 75%
The amount is 45
The base is 60
Step-by-step explanation:
1) Set up the equation:
60x=45
2) Divide both sides by 60:
x=45/60
3) Simplify the fraction:
x=0.75
4) Write the decimal as a percent:
75%
Answer:
It's either 9 or 0.24 repeated
Step-by-step explanation:
I wasn't sure which of those would be the answer for your equation, since your equation didn't make sense.
8 + 1/3 (3) = 9
8 + 1/3 (3/1) = 9
8 + 3/3 = 9
8 + 1 = 9
---------------------- This will be the second equation:
8 + 1/33 = 0.24 repeated
8/1 + 1/33 = 0.24 repeated
8/33= 0.24 repeated
Hope this helped !!
2/6 divided by 4/12
First, make 2/6 have a denominator of 12 to complement the fraction 4/12
2/6=4/12
4/12 divided by 4/12 is 1
So, 1 would be your answer.
Hope I helped!
For the equation Y value is -45.
Answer:
The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).
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:
95% 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 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).
