Answer:</h2>
We will use substitution to solve this system for x.
Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.
We now have our solution.
D.
We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.
Since the equation checks out, our solution is correct.

Answer:
1. a. Weak
2. r^2=0.0169
The variation in the price of the wine explained by the variation in the weight of the bottle is 1.69%.
Step-by-step explanation:
The correlation between the weight of the wine bottles and the price of the wine is r=0.13.
The values for r goes from r=-1, where a perfect negative correlation to r=1 for a perfect positive correlation. The value r=0 indicates no correlation at all.
Then, a value of r close to 0 indicates very weak correlation between the two variables.
The value for r^2 in this case is:
The value of r2 can be interpreted as the proportion of the variation in the dependant variable explained by the independent vairable. In this case, the variation in the price of the wine explained by the variation in the weight of the bottle is 1.69%, which is very close to 0.
