Answer:
B (0.312, 0.364)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, 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:
1289 randomly selected American adults responded to this question. This means that 
.
Of the respondents, 436 replied that America is doing about the right amount. This means that 
.
Determine a 95% confidence interval for the proportion of all the registered voters who will vote for the Republican Party.
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 95% confidence interval is:
B (0.312, 0.364)
Answer:
(-3, 3)
Step-by-step explanation:
Substitute for y:
x+6 = -2x -3
3x = -9 . . . . . . . add 2x -6 to both sides
x = -3 . . . . . . . . divide by 3
y = (-3) +6 = 3 . . substitute for x in the first equation
The solution is ...
(x, y) = (-3, 3)
The Surface area of the cube will be 433.5 square feet. Then the correct option is C.
<h3>What is a surface area of a cube?</h3>
Suppose that: The side length of the considered cube is L units. Then, we get:
Surface area of that cube = 6L² square units.
Bella is wrapping a cube shape box that measures 8.5 inches along each side.
The edge length of the cube is 8.5 meters.
Then the Surface area of the cube will be
Surface area = 6 x 8.5²
Surface area = 6 x 72.25
Surface area = 433.5 square feet
The Surface area of the cube will be 433.5 square feet.
Then the correct option is C.
