A will represent Anna. k will represent Kylie.

7a+7k=231
a=9+k

Substitute for a
7(9+k)+7k=231
63+7k+7k=231
14k=168
k=12

Then plug in the k value
a=9+12
a=21

Final answer: Anna=21 mph, Kylie= 12 mph

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 \frac{0.1}{1.96} does not equal to 15.
