Answer:
Step-by-step explanation:
x=3 and x=-4 are parallel, vertical lines
:::::
x-y = 3, slope = 1
2x-2y = 10, slope = 1
Parallel lines
Answer:
Quadratic polynomial is x^2 - x - 20
Answer:
Option B:


Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:

A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:

Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
The answer is 6n^3+n^2+6n-4 I hope I helped you!
