Answer:
so im not sure what youre asking but hopefully i can help you with this a little. if you change the fractions to all have the same denominator, it will be easier for you to solve. since they can all have eight as a denominator, antonio wouldve eaten 2/8 of a box of cereal, jamie 1/8, and marianna 4/8. hope that helps a little :)
Step-by-step explanation:
Answer:
19 is the square root of 361.
Answer:
It would be A
Step-by-step explanation:
The other answers do not make sense.
First of all: Area= length x width.
Two of the options were larger than 49.7, so we could cross those out
Then, we look at A and B.
46.2 x 3.5 = 161.7, which is WAY larger than 49.7.
Since we have no option left to test, we can test A:
14.2 x 3.5= 49.7
Now we cam be sure that the answer is 14.2, or, A.

Answer:
(0.806, 0.839)
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
.
Suppose we take a poll (random sample) of 3653 students classified as Juniors and find that 3005 of them believe that they will find a job immediately after graduation.
This means that 
99% 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 answer is (0.806, 0.839)
