The answer is N<span>≥ 178. I just had this question and that was right.</span>
C. 5x+7=22 since diameter is equal to double the radius. radius=11 so diameter equals 22. then just make 5x+7 = to 22
If the digit of 0 is allowed, then:
1/(10*9*8)= 1/720
If it is not permitted, then:
1/(9*8*7)= 1/504
I hope this helps you!
Brainliest answer is always appreciated!
Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
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:

In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that 
95% confidence level
So
, z is the value of Z that has a p-value of
, so
.
Margin of error:



The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Answer:
all real nunbers
Step-by-step explanation:
when we exchange the place of x and y and solve for y we get the equation y=x^2 + 2
any number inserted in x will give a value y
