1 answer:

6 0

6 and 9/24 + 9 and 4/24 is the number you have to change it to to get your answer. After that, you add, and get 15 and 13/24.

A car traveled 63.4 miles in 72 minutes. At this rate, how far will it travel in 90 minutes?

Mamont248 [21]

*ahem* the actual Awnser is 79.25 because 63.4 divided by 72 is 0.8805 and if you multiply that by 90 you get 79.25

That's the last one because you can factor to get

Annual starting salaries for college graduates with degrees in business administration are generally expected to have a populati

valkas [14]

Answer:

A sample of 139 should be taken.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1 - 0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1 - \alpha$ .

That is z with a pvalue of $1 - 0.025 = 0.975$ , so Z = 1.96.

Now, find the margin of error M as such

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

Population standard deviation of $3,000.

This means that $\sigma = 3000$

How large a sample should be taken if the desired margin of error is $500?

A sample of n is needed.

n is found when M = 500. So

$M = z\frac{\sigma}{\sqrt{n}}$

$500 = 1.96\frac{3000}{\sqrt{n}}$

$500\sqrt{n} = 1.96*3000$

Dividing both sides by 500

$\sqrt{n} = 1.96*6$

$(\sqrt{n})^2 = (1.96*6)^2$

$n = 138.3$

Rounding up:

A sample of 139 should be taken.
