Step-by-step explanation:
Given that the mean salary for a new teacher in your town is $48,000
You believe it is higher for new teachers in a neighboring town.
So to prove or disprove your claim you have to show statistical evidence.
For that hypothesis testing is necessary.
You must conduct a hypothesis test for comparing the mean of salary of new teacher with neighbouring places
The hypotheses wouldbe
where mu is the average for neighbouring states.
Answer:
The coordinates of point E are (3,-2)
Step-by-step explanation:
we know that
The diagonals of a parallelogram bisect each other
That means ----> The coordinates of point E is the midpoint diagonal AC or the midpoint diagonal BD
The formula to calculate the midpoint between two points is equal to
<u><em>Verify both cases</em></u>
<em>Find the midpoint AC</em>
we have the points
A(1,1) and C(5,-5)
substitute in the formula
<em>Find the midpoint BD</em>
we have the points
B(8,5) and D (-2,-9)
substitute in the formula
therefore
The coordinates of point E are (3,-2)
