So one key thing to remember here is that the direction of the correlation is irrelevant, that is it does not matter if your correlation is + or - what matters is how close that number is to 1.0.
To help you out here are the ranges of correlation strength
- 0.70. A strong relationship
- 0.50. A moderate relationship
- 0.30. A weak relationship
So to start off with 0.26 and 0.18 are very small correlations so you'd call those weak correlations.
Let me know if you need help doing the other ones? It should be simple enough with the data I gave you :)
The function is defined only if 
. So, the leftmost point is 
, and we have
So, the first point is 
The three additional points seem arbitrary, so let's choose 
. We have:
So, the second point is 
So, the third point is 
So, the fourth point is 
Answer:
(0,0)
Step-by-step explanation:
They intersect at point (0,0)
He has a total of $58.19.
1 day = $2.74
58.19/2.74
21.24
You can't have 21.2 days, so you need to round down to 21.
Jim can buy lunch for 21 days before he runs out of money on his account.
