The correlation coefficient of a scatter plot with line of best fit shown will be the slope of the line.
We can eliminate last 2 choices because the line is clearly a downward sloping line and it's slope wont be positive.
From the first two, it looks like the plot's slope is very close to -1. So we take -0.91, instead of -0.35. <em>[note: 0.91 is more steeper than 0.35 (which is very relaxed)]</em>
ANSWER: -0.91
The correct formula for this is as follows:

where n is the number of compounding periods per year, and r is the annual interest rate as a decimal,
Plugging the given values into the formula, we get:

This equation can be simplified to:

Taking logs of both sides gives:

which can be rearranged to get:

So it will take about 5.864 years for the amount to reach $4550.

You would do 3,600 times .08 which would equal 288 then you would multiply 288 by 10 to get 2880 which is your answer
Glad I could help
I think the answer is 35/2 or 17.5. Hopefully this helped.
