Answer: no solution
Step-by-step explanation:
I believe it’s 30,180,000
First do 4% -> 0.04x15=0.6
0.6+100=100.6x300,000
But then again I’m not too sure so double check
Which ordered pairs are in the solution set of the system of linear inequalities? (4, 2)
Answer:
A and B
Step-by-step explanation:
Answer:
The sample size needed is 2401.
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 of the interval is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
Estimate the sample size needed if no estimate of p is available so that the confidence interval will have a margin of error of 0.02.
We have to find n, for which M = 0.02.
There is no estimate of p available, so we use
The sample size needed is 2401.
