Answer:this is an absolute value function is there more to the question
Step-by-step explanation:
Answer:
Foci 
Vertices:
Eccentricity, e=
Length of latus rectum=
Step-by-step explanation:
We are given that


The equation of hyperbola is along y-axis because y is positive
Compare the equation with
(Along y-axis)
We get
a=1, b=1/4





Therefore,
The coordinates of foci=
The coordinated of vertices=
Eccentricity, e=c/a

Length of latus rectum=
Length of latus rectum=
Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0): 
Alternative hypothesis (H1): 
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no
