Answer:
A sample of 16577 is required.
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 of:
99% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
She wants to estimate the proportion using a 99% confidence interval with a margin of error of at most 0.01. How large a sample size would be required?
We have no estimation for the proportion, and thus we use 
, which is when the largest sample size will be needed.
The sample size is n for which M = 0.01. So
Rounding up:
A sample of 16577 is required.
Answer:
3 * n^(1/6)
Step-by-step explanation:
The square root can be written as ^ 1/2
The cube root can be written as ^ 1/3
So the sixth root can be written as ^ 1/6
3 * n^(1/6)
A consistent system of equations is a system with intersecting lines and lines that have the same equation.
A consistent system is the system of equations with at least one solution or infinite number of solutions.
So , the intersecting lines will always have a solution and the lines with the same equation will have infinite number of solution.
The graph of a system of equations with different slopes will have no solutions. Correct option in "Never"
If the system of equations have different slopes then the equations are not parallel, hence the equations will always have a solution.
Answer:
-4/7, -1/3, -0.1, 0, 0.1
Step-by-step explanation:
Answer:
18/40
Step-by-step explanation:
1. Find a common denominator
8, 16, 24, 32, 40
5, 10, 15, 20, 25, 30, 35, 40
2/8 times 5= 10/40
1/5 times 8= 8/40
10/40 plus 8/40= 18/40
