If earning more money from a college degree occurs, a researcher is interested in finding out. She is aware that the average annual household income in thousands is μ<=80.
The null hypothesis is a claim made about the population parameter in relation to the test's goal and in opposition to the alternative hypothesis.
- The term "null hypothesis" refers to a researcher's attempt to reject or "nullify" a commonly held assumption (such as that the sky is blue). A null hypothesis is "a statistical theory suggesting that no statistical relationship exists between given observed variables," according to a more formal definition.
- It always contains = , ≤ , ≥ signs.
- The results will be examined using a one-tailed hypothesis test.
Hence, μ<=80

To calculate simple interest, you first need to multiply the original amount by the percentage of the money which is going to be added.
In this situation, 500 x 0.05 is the interest which will be added each year.
Therefore, $25 will be added each year. Since it is over 4 years, it is (25*4).
So the account will have earned $100 of simple interest.
Although the account will contain $600, it will have EARNED $100 of interest since it started with $500 already.
Answer - A $100 of simple interest will be earned.
Answer:
take your pick. Each has its own reason.
Step-by-step explanation:
As with a lot of "doesn't belong" problems, the one that is different depends on your criteria. In the attached figure, each one "doesn't belong" for a different reason. Those reasons are listed below each number line.

I might choose the lower left: "addition, not subtraction", as it is the only one with arrows in the same direction. That makes its difference from the others more obvious, perhaps.
Answer:
C.
Step-by-step explanation:
This equation is properly distributed. 6×4=24 and 6×-3w= -18w. the equation becomes 24-18w
Answer:
A. C(x) = 30.000 + 2500x
B. R(x) = 3125x
C. 48 items break even point
Step-by-step explanation:
A. The cost function C(x) is fixed cost plus variable cost.
In this case overhead works as fixed cost, we can write:
C(x) = 30.000 + 2500x
B. Revenue R(x) would be the price multiplied by quantity of items (x).
R(x) = 3125x
C. Break even point
To get the break even point we set R(x) = C(x) and find the value of x.
R(x) = C(x)
3125x = 30.000 + 2500x
3125x-2500x=30.000
625x=30.000
x=30.000/625
x=48
It means when you sell 48 items the costs will even revenue. So if you sell more than 48, then it's going to be profitable. If you sell less than 48, you will be losing money.
