Answer: We discover two outcomes:
1000 - 998 = 2
1001 - 999 = 2
Step-by-step explanation:
The problem can be stated as:
****-*** = 2
Where each asterisk symbolizes a distinct digit; here with a 4-digit number subtracting a 3-digit number to yield a difference of 2.
This can be represented as 99*, where we can increase any digit from 1 to 9 and we will achieve a 4-digit result:
So we rewrite it this way:
1000 - 998 = 2
When we add one to each side, the difference remains preserved, maintaining equal digit counts:[
1000 - 998 + 1 - 1 = 2
(1000 + 1) - (998 + 1) = 2
Thus, 1001 - 999 = 2
A simple case would also yield further solutions where digits can be zeros, for instance:
0004 - 0002 = 2
However, this trivial solution may be disregarded. This leads us to conclude that we have two unique solutions.

The correct answer is:
She can ascertain that while there exists an association between the variables, a correlation does not exist, and causation cannot be established.
Explanation:
Due to the arch shape of her graph, it indicates that as one variable varies, the other also changes. This indicates an association exists between these variables.
Nonetheless, given that the graph does not follow a linear pattern, no correlation can be claimed. As there is no correlation, causation cannot be determined.
