Answer:
The interval 52% to 58% is based on a procedure that includes the true population value 95% of the time.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95% confidence
We are 95% sure that the interval contains the true mean/proportion, and thus, the correct option is:
The interval 52% to 58% is based on a procedure that includes the true population value 95% of the time.
Ok so when you add fractions, the denominators have to be the same, therefore: (whole numbers you can still add)
5(1/2)+5(1/2)= 10(2/2), which equals to 11.
5(1/2) is also 5.5, since 1/2 is 50/100.
5.5 + 5.5 = 11
Complementary angles add up to 90°
Let one of the angle be x.
The other angle is 29x.
x + 29x = 90
30x = 90
x = 3
29x = 29(3) = 87
Answer: The two angles are 3° and 87°
The answer is 63 :) hope i helped
Its c because yea it just is udk how to explain it
