<span>The answer is 5.5 gallons. One cup is 0.0625 gallons. If each guest will drink 2 cups of punch, 20 guests will drink: 20 * 2 cups = 40 cups = 40 * 0.0625 gallons = 2.5 gallons. So, 20 guests will drink 2.5 gallons. The host had 8 gallons and after the party he will have: 8 gallons - 2.5 gallons = 5.5 gallons.</span>
It would be 3 because you can divide all of them in to rows of three and still have the same kind of plants in each row.

Answer: 0.51</h3>
Add up the P(x) values that correspond to x = 2 through x = 4
0.07+0.22+0.22
So we have a 51% chance of getting an x value such that 1 < x < 5
Isolate the x. Note the equal sign. What you do to one side, you do to the other. Subtract 45 from both sides
x + 45 (-45) = 11 (-45)
x = 11 - 45
x = -34
-34 is your answer
hope this helps
