Which expression finds the measure of an a 126 degree angle?
1 answer:
Answer: OPTION D.
Step-by-step explanation:
<h3> The complete exercise is: "Which expression finds the measure of an angle that is coterminal with a 126° angle?</h3><h3> A.Coterminal angles are those angles that are in standard position and and whose terminal sides are common.
If an angle is given in degrees, you can find the angles that are coterminal with that angle by adding or subtracting 360 degrees.
By definition, knowing and angle , the following expression shows all the angles that are Coterminal with the angle
, for any integer "n":
In this case, you know that:
Then, you can say that its coterminal angles are:
Knowing that "n" is an integer, if this is , you get the following expression:

Answer:
The 99% confidence interval for p in this case is (0.3317, 0.5883).
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 zscore that has a pvalue of .
Randomly selects 100 students from the school and asks the President to name each one. The President is able to correctly name 46 of the students.
This means that:
99% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for p in this case is (0.3317, 0.5883).
