0.27, I know 3 times nine does equal 27. So I divide 100 by 27.
Answer:
28,550.33333
Step-by-step explanation:
28,550.33333 + 3 = 28,553.33333
28,553.33333 x 3 = 85,659.99999
85,659.99999 ÷ 2 = 42830
Answer:
A sample of 16577 is required.
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 z-score that has a p-value of
.
The margin of error is of:

99% confidence level
So
, z is the value of Z that has a p-value of
, so
.
She wants to estimate the proportion using a 99% confidence interval with a margin of error of at most 0.01. How large a sample size would be required?
We have no estimation for the proportion, and thus we use
, which is when the largest sample size will be needed.
The sample size is n for which M = 0.01. So






Rounding up:
A sample of 16577 is required.
E because 6 times .375 which is 3/8 = 16
Yes! It can!
The 12 meters will be the hypotenuse, the 10 meters can be a side and the 8 meters can be another side.
