Answer:
The minimum number of drivers you would need to survey is 601.
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 z-score that has a p-value of .
The margin of error is:
95% confidence level
So , z is the value of Z that has a p-value of , so .
What is the minimum number of drivers you would need to survey to be 95% confident that the population proportion is estimated to within 0.04?
The number is n for which M = 0.04.
We don't have an estimate for the proportion, so we use . Then
Rounding up:
The minimum number of drivers you would need to survey is 601.

Answer: 8+(-40)
Step-by-step explanation:
You’re using distributive property you would multiply 8 and c which equals 8 because c=1 and then you would multiply 8•(-5) which would be -40 so your answer would be 8+(-40)
