I’m Just Built Different
Step-by-step explanation:
step 1. let's assume they are drawn without replacement and probability is denoted P.
step 3. P = (5/17)(4/16)(3/15)
step 4. P = (5/17)(1/4)(1/5)
step 5. P = 5/340
step 6. P = 1/68 = 0.0147 = 1.5%
Story:
There is a tank that can fill 4 liters of water. The 2/3 of the tank has been filled with water. How much liters have the tank filled with water?
Solution of story:
<u>We know that:</u>
- Tank = 4 liters
- 2/3 x 4 = Water filled in tank
Multiply both the terms to get the answer.
<u>Solution:</u>
- 2/3 x 4 liters
- => 8/3 liters = 2 2/3 liters
Hence, 2 2/3 liters has been filled with water.
Hoped this helped.
If x is the number of tickets she has left, then 2x is the number she has used (2×number of rides she has gone on). So the number she has left would be...
14 - 2x
We can now find an equivalent expression by replacing the x with a number... for example...
14 - 2(2)
This would be if she rode two rides. You could solve the equation like this...
14 - 2x =
14 - 2(2) =
14 - 4 = 10
After 2 rides she has 10 tickets left.
