To find the probability of picking a five dollar bill and then another five dollar bill, you will find the chance of picking a five dollar bill the first time, and multiply by the probability of picking another one the second time.

There is a 3 out of 9 chance the first time because there are 3 - $5 dollar bills, and 9 total bills.

The second time there will be a 2 out of 8 chance, because if you picked a $5 dollar bill the first time, there should be 2 - $5 bills left and 8 total bills.

3/9 x 2/8 or 1/3 x 1/4 = 1/12 chance.

PLEASE HELP URGENT THANK YOU

So far the only true statement I see is that function f is increasing whilst function g is decreasing.

I cannot say yes to the first one as there is a lack of x-intercepts.

Past the interval of 0,2, there are no changes in the line of function g as it remains the same despite the increase in y. Function f on the other hand has a rate of change. 

The y-intercepts are the same (positive 2) so the third statement is out.

50 cases in 44 minutes equals how many cases in 60 minutes
Blizzard [7]
To solve this, set up a proportion, crossmultiply, and solve for x. 

Let x = the unknown amount of cases in 60 minutes.

\frac{50}{44} = \frac{x}{60}
44x = 50(60)
44x = 3000

Divide both sides by 44 to isolate variable x
x = 3000 / 44
x ≈ 68.1818 (the 18s repeat forever)

Rounding to the closest case and assuming the rate stays constant, you would get approximately 68 cases in 60 minutes. If you need not round to the nearest case, you would get approximately 68.18 cases in 60 minutes.
