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.

Find answers below
Step-by-step explanation:
First know that any value raise to power zero is 1 and also according to the inverse law;
a⁻ⁿ = 1/aⁿ
Given the following
a) (-123)⁰ = 1 ()Note that any value raise to zero is 1
b) 43⁻⁵ = 1/43⁵
1/43⁵ = 1/147,008,443
c) 1/15⁻⁶ = 1/(1/15⁶)
1/(1/15⁶) = 1*15⁶/1
1/(1/15⁶) = 15⁶
d) -(1353348)⁰
= -1 (anything raise to zero is 1)
e) 13⁻⁴ = 1/13⁴
= 1/28,561
Assumed that sides are equal
- 5x-3=3x+1
- 5x-3x=1+3
- 2x=4
- x=2
