Answer:
D) the standard error for her sample is 15
Step-by-step explanation:
Samantha is 95% certain that between 50% and 70% of the first year students agree that they should be able to bring a car to campus.
Here
- 95% is the confidence level.
- The range between 50% and 70% indicates 95% confidence interval.
- 60% is the average proportion of the first year students at her university think they should be able to bring a car to campus.
- 10% (0.1) is the margin of error from the mean
Since standard error can be obtained by dividing margin of error by the z-statistic of the confidence level which is 1.96. The standard error for her sample 
does not equal to 15.
Answer:
(0,4)
Step-by-step explanation:
Subtract the first equation from the second, obtaining y = 4. Then substitute 4 for y in the first equation, obtaining x + 2(4) = 8; it follows that x = 0.
The solution is (0,4).
Since you did not provide the coordinates, I can't provide an exact answer.
However, I can tell you this; from the initial x-coordinate, move right 5 units. from the initial-y coordinate, move up 1 unit and you will have your answer.
Answer:
if you're asking for the reciprocal.
if you're asking the opposite of a reciprocal.
Step-by-step explanation:
The reciprocal is the number flipped or in this case
Answer: 328 feet, 1 inch
Step-by-step explanation:
3.281 feet makes 1 meter
To solve the question, Multiply the value by 3.281:
100 meters = 100 x 3.281 feets
=328.1 feet
I hope this helps.
