(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)
To determine the slope using two points lie on the line, we could use the following formula
m =
plug in the numbers
m =
m =
m =
m = undefined
The slope is undefined, the line is vertical

Answer:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
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 .
95% confidence level
So , z is the value of Z that has a p-value of
, so
.
In a sample of 234 individuals over the age of 25, chosen at random from the state of Oregon, 48 did not have a high school diploma.
This means that
The upper limit of this interval is:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
Answer:
The inverse is (x) =
Step-by-step explanation:
(By the way, (x) is f negative one of x, like f(x), but inverse)
f(x) = - 4 is the same as y =
- 4
y = - 4 start with the equation.
x = - 4 switch x and y.
x + 4 = add 4 to both sides.
= y square both sides.
(x) =
change y to the inverse f(x) format.
I hope this helps! :)
