Answer: 
Step-by-step explanation:
It is important to remember that, by definition, proportional relationships have the following form:
Where "k" is the constant of proportionality.
We know that Maddy assume that the relation between the volume and the weight is proportional.
Then, let be "V" the volume in liters and "w" the weight in kilograms.
We can write the following equation:
So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":
In order to solve the exercise, substitute the value of "k" and 
into the equation and solve for "w". Then:
12 - x = 5
Subtract 12 from both sides
12 - 12 - x = 5 - 12
- x = - 7
Divide both sides by -1
-x/-1 = -12/-1
x = 7
Answer:
Pat drank 26/6 (4 1/3 or 13/3) cups of punch.
Step-by-step explanation:
Here is how I would solve this-
What is the question? How much punch did she drink in all?
What do we need to know? 11/3 + 4/6 cups of punch.
How can we make them have a common denominator? 22/6 + 4/6
Add them together! (22 + 4 = 26) so you get 26/6
Final Answer = Pat drank 26/6 (4 1/3 or 13/3) cups of punch.
Hope this helps! Good luck and let me know if this is right!

Answer:
Step-by-step explanation:
Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz
For testing this claim, in Statistics we perform a certain measures called hypothesis testing.
For this first step is to create null and alternate hypothesis.
Normally null hypothesis would have some statistic = something
Here we want to test the mean weight of perfume
Hence null hypothesis would be
H0: mu = 8.9 fl oz.
Alternate hypothesis would be opposite of this claim
i.e.
Ha: mu ≠8.9 fluid oz
Hence answer is
