For this case we have the following equation:
We apply distributive property on the left side of the equation:
We simplify the left side of the equation:
Different signs are subtracted and the major sign is placed.
On the right side we must take into account that:
So:
We add x to both sides of the equation:
We subtract 2 from both sides of the equation:
We multiply by 3 on both sides of the equation:
We divide by 8 on both sides of the equation:
Thus, the solution of the equation is:
Answer:
Answer:
The events must be independent.
Step-by-step explanation:
The only assumption that must be made is that the events are independent. That is, the amount of soda in a given can does not depend on the amount of soda of any previous can filled at the same facility.
If this assumption holds, then the probability of finding exactly k cans of soda filled correctly would be
where
are combinations of 100 elements taken k at a time.

Step-by-step explanation:
search it on googIe.
w = number of weeks
b(w) = number of books read after w weeks
====================================
b(w) = 12 translates to "after w weeks, Katy will have read 12 books" or put another way "Katy will have read 12 books after w weeks". The 'w' is a placeholder for some number
====================================
b(2) = 10 means "Katy has read 10 books after 2 weeks". We use the same basic idea talked about above, but we replace w with 2. At the same time, we use 10 instead of 12.
====================================
b(3) = f means "Katy has read f books after 3 weeks" or "after 3 weeks, Katy has read f books". Like w, the f is a placeholder for some number.
Answer:
2/6 or 1/3
Each number has 1 /6 probability. But since you can accept either 3 or 4, the probability is better and is 2/6 or simplified to 1/3.
