n=# of nickels
q=# of quarters
$12 is 1200 cents
5n+25q=1200
n=q
substitute q for n or n for q
5q+25q=1200
30q=1200
q=1200/30
q=40 quarters and therefore n=40 nickels
40 quarters is $10 and 40 nickels is $2, therefore you have $12
Hope this helps.

Answer:
d. The average is equal to 12 ounces.
Step-by-step explanation:
In this problem, the drink filling machine must be perfectly calibrated at 12 ounces since it needs to be shut down in cases of overfilling (mean > 12 ounces) and underfilling (mean < 12 ounces). Therefore, the correct approach would be to test if the mean is 12 ounces and the correct set of hypothesis would be:
The correct alternative is d. The average is equal to 12 ounces.
I think the answer is as follows:
70/574 = x/100
574x=7000
574/7000 = .082
final answer is 820
820 x 70% = 574
The domain of a function is all the possible input or x values.
In this problem, we can see the function starts at (0, 0) tapering off to the right infinitely. This means that every positive x value including 0 is in the domain.
0, 1, 2, 5 are all in the domain.
