Answer:
Lowering the level of significance, α increases the probability of making a Type II error, β.
Step-by-step explanation:
Lowering the level of significance, α increases the probability of making a Type II error, β.
This is because the region of acceptance becomes bigger, and it makes it less likely for one to reject a null hypothesis, when it is false, the type II error.
Make one of the variables drop out.
I'd go for the y since it's easiest in this problem.
Time the top equation by -1.
This changes the system to:
Add the equations.
The equation would be:
Or simply:
Solve for x by dividing.
Then, plug x into one of the original equations to find y.
I'm going to use the first one since the numbers are smaller, but you CAN use either.
Put these into an ordered pair.
(0,1)
That is your answer.
Hope this helped!

Answer:
320
Step-by-step explanation:
192/0.6
Prob(there are no sixes after the roll) = (5/6)^4 = 625/1296
Prob( at least on six is rolled) = 1 - 625/1296 = 671/1296 = 0.518 to nearest 1/1000
Wastewater is filling the barrel at 11 quarts per hour, meaning that after 1 hour, 11/12 of a barrel will be full.
How many hours will pass before 120 barrels are full?
(Try to come up with an equation for this, if you don't know, ask me in the comments and I'll help you out further~)
