The answer to your question is 8, because you replace z with 2
Answer and Step-by-step explanation:
f(x) =
Where x is time in years and f(x) is the amount of money the truck is worth each year.

Answer:
12.50 x 4 hours = $50
Step-by-step explanation:
It is advisable to pick the hour based form of payment because this gives room for flexibility in terms of time scheduled for the work.
Also, if the hourly based rate of $12.50 is chosen, this means he only have to work for 4 hours to break even with $50 ( 4hours x $12.50 = $50).
Hence, Paul is advised to pick the hourly based payment if he plans to work for more than 4 hours.
Nevertheless, if he plans to work for less than 4 hours, he is advised to go for $50 payment schedule.
The reason for choosing the hourly pay is that $12.50 paid per hour means if he works for 24 hours,the pay will be $12.5×24=$300...
Which means he will surely earn more by working hourly compared to working being paid $50.
The difference between the $50 and the hourly pay is so much that he will rather go for the highest pay.
Answer:
The sample size is 1875.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
Sampling error of 0.03.
This means that
99.74% confidence level
So , z is the value of Z that has a pvalue of , so .
25% of all adults had used the Internet for such a purpose
This means that
What is the sample size
The sample size is n. So
Simplifying by 0.03 both sides
The sample size is 1875.
