Answer:
1.309 rad
Step-by-step explanation:
We are told to convert 75° to radians.
# we know that 1° is equivalent to 0.01745radians.
-To convert any angle degree to radians, we multiply it by π/180 or 0.01745rad:

Hence, the radian equivalent of 75 is 1.309 rad
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! :)
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.
