You simply draw one with an angle greater than or less than 90 degrees.
For this case we have the following system of equations:
y = -5 / 3x + 4
y = -5 / 3x + 3
We note that the lines have the same slope:
m = -5 / 3
Therefore, the lines are parallel.
Thus, the system has no solution.
Answer:
It has no solution (parallel lines).

Answer:
The confidence interval for the mean is given by the following formula:
Step-by-step explanation:
1) Notation and definitions
number of people or things with a specific characteristic.
random sample taken
estimated proportion of people or things with a specific characteristic.
true population proportion of people or things with a specific characteristic.
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
The population proportion have the following distribution
If we have all the conditions required in order to construct the confidence interval:
1) Random sample selected
2) np >10
3) n(1-p)>10
Then the confidence interval for the mean is given by the following formula:
Answer:
The second option.
Step-by-step explanation:
The reasoning behind this is because it is a mixed fraction and the rest aren't.
Hope that helps!
