Answer:
The correct math operation to determine the unit price is division
Step-by-step explanation:
In 2-liter bottle of water:
67.6 ounces cost $1.39, then
=> 1 ounce costs
Well to find this answer, you want to divide $1.39 by 67.6. When you do this you get 0.0205. This is roughly 2 cents per ounce.
point d that is it because I knwo
So the table means that there are 20 1's, 120 2's, 40 3's, and 20 4's.
The total number is 20+120+40+20 = 200.
So the probability of each is:
1: 20/200 = 0.10
2: 120/200 = 0.60
3: 40/200 = 0.20
4: 20/200 = 0.10
w = l - 3
w = 9 - 3
w = 6
//
l = 9
p = 2(9) + 2(6)
p = 30
