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
.
For this problem, we have 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 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U.S. economic problems is (0.4894, 0.5706)..
Answer:
B- $38.00
Step-by-step explanation:
Since there are two adults, you would multiply the cost of adults by number of adults. in this case that would be $10.75 x 2= $21.50. do the same for the kids and you will get $5.50 x 3 = $16.50. add 16.50 and 21.50 and you will get $38.00 which is your answer
hope this helped :D

Answer:
x=3(one solution)
Step-by-step explanation:
2x+2=3x-1
subtract 2 from both sides
2x=3x-3
subtract 3x from both sides
-x=-3
divide both sides by -1
x=3
