Answer:
The answer to your question is because it is a solution of each equation.
Step-by-step explanation:
Data
Point (3,4)
Equation l y = 1/3x + 3
Equation ll y = 2x - 2
Process
1.- To test is a point is solution to a system of equations,
-Substitute the point in both equations
Equation l 4 = 1/3(3) + 3
4 = 1 + 3
4 = 4 The point is a solution because
4 = 4
Equation ll 4 = 2(3) - 2
4 = 6 - 2
4 = 4 This point is a solution for the second
equation but not for the first one.
2.- Conclusion
As the point is a solution of each equation, it is a solution of the system.
Answer:
The maximum value of the confidence interval for this set of survey results is 51.73%.
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds depend on the sample proportion and on the margin of error.
The lower bound is the sample proportion subtracted by the margin of error.
The upper bound is the margin of error added to the sample proportion.
In this question:
Sample proportion: 46.1%
Margin of error: 5.63%.
Maximum value is the upper bound:
46.1+5.63 = 51.73
The maximum value of the confidence interval for this set of survey results is 51.73%.
