Answer:
295 mi
Step-by-step explanation:
we can write this as an equation. the base fee, with no miles traveled is 25. this will be our y intercept, or b in the equation y = mx + b
our slope is .4
for every 1 mile increase for x, our y increases by .4
so:
y = .4x + 25
set this equal to 143.40
143.40 = .4x + 25
x = 295 mi
Answer:
On this case a margin of error of means that the true population proportion is 3.5% above or below the estimated proportion calculated from the sample. And this value helps in order to find the limits for a confidence interval with a confidence given.
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
Solution to the problem
The margin of error for the proportion interval is given by this formula:
(a)
On this case a margin of error of means that the true population proportion is 3.5% above or below the estimated proportion calculated from the sample. And this value helps in order to find the limits for a confidence interval with a confidence given.
I believe it’s b because of the way that it is
Solve for k by simplifying both sides of the equation, then isolating the variable.
k= 14/5
Since

is not a rational expression, there are no asymptotes.
