Answer:
Think it is A as 4x20=80.
Hi, I was able to find the full context for this one from another source:
<span>"Juanita has a storage closet at her shop with extra bottles of lotion and shower gel. Some are scented and some are unscented. If she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel."
For the "shower gel" and "scented" to be independent given the situation above, we need to show that P(A | B) = P(A). You can get this equation from the definition of "independence" where P(A </span>∩ B) = P(A)*P(B) and the formula for conditional probability P(A | B).
We only have the given P(shower gel) = 42% therefore the event "shower gel" must be the variable A.
ANSWER: To show independence of the two events, P(shower gel | scented) = 42% must be true.
GCF means "greatest common factor."
When I learned this, I was told to try 5 numbers and see if they work and if not, it might be 1.
Those numbers are 2, 3, 5, 7, and 9.
2 goes into 56 but not 21.
3 goes into 21 but not 56.
5 doesn't go into 56 nor 21.
7 goes into both 56 and 21.
9 doesn't go into 56 nor 21.
So since 7 works with both numbers, try numbers divisible by 7 (i.e. 14, 21...)
14 goes into 56 but not 21.
21 goes into 21 but not 56.
You can't go any higher than that since then it would be going above 21.
So the GCF of 56 and 21 is 7.
Answer: 864
Step-by-step explanation:
Using inverse operations you can multiply 12 and 72 to get 864 and that divided by 12 gets 72
