There are 7 total numbers, and 4 are even. That means the probability is 4/7.
Answer:
32 bottles
Step-by-step explanation:
In this scenario, we have to divide 8 by 1/4 to see how many of those 1/4-liter bottles can be filled with 8 liters of water. So, let's go ahead and see how this looks mathematically, then we'll start simplifying:
÷ 
Dividing by a fraction is the same as <em>multiplying by that same fraction's reciprocal</em>, so we can rearrange our math to make things easier.
× 
Now, we can multiply the numerators and the denominators.
×

So 32 of those 1/4 liter bottles can be filled from a jug containing 8 liters of water. Hopefully this was helpful! If anything was confusing or didn't make sense, let me know so I can make things clearer. :)
For this, we just need to solve the function when x = 4. So firstly, plug in 4 in the x variable.

Next, solve the exponents and multiplications: 
Next, combine everything on the right side of the equation, and your answer will be y = -4
