Angie has a total of 6.5 yards of ribbon. Her goal is to take advantage over it by making a wreath. Each wreath has length of 1 1/3 yards.
In order for us to know how many wreath will be made, we'll divide the fraction to the total length of the ribbon.
= 6.5 / 1 1/3
= 6 1/2 / 4/3
= 13/2 * 3/4
= 39 / 8
= 4.875
So, there are 4 bows or wreath can be made.
14. x ^2 = 12^2 + 7 ^2 = x = sqrt (12^2 + 7^2) = sqrt(193)

Answer:
a) n = 1037.
b) n = 1026.
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 
The margin of error is:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
(a) Assume that nothing is known about the percentage to be estimated.
We need to find n when M = 0.04.
We dont know the percentage to be estimated, so we use
, which is when we are going to need the largest sample size.






Rounding up
n = 1037.
(b) Assume prior studies have shown that about 55% of full-time students earn bachelor's degrees in four years or less.

So






Rounding up
n = 1026.
