We have the next two equations:

And

We need to find f(3)/g(3)
First, let's find f(3):

Then g(3):

Now, the equation f(3)/g(3) :

-27/11 is the result.
Start the graph at the <em>y</em>-intercept. At 0 hours, he will make $0, so (0, 0) is the <em>y</em>-intercept. From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph. The graph is attached.
When dealing with statistics (probabilities of events etc) and histograms
The answer is B.) one
Hope this helps :)
