Look at all the factors of both monomials
6bc = 2*3*b*c
9b^2c = 3*3*b*b*c
All of the factors they have in common
3*b*c
so 3bc is the GCF
Answer:
<u>The cost of gas per gallon in Canada is $ 2.95 (Rounding to the nearest cent)</u>
Step-by-step explanation:
Let's solve this question, this way:
1. Let's convert liters to US gallons:
1 US gallon = 3.785412 liters
1 liter = 0. 26417204 gallon
2. Let's calculate the cost per gallon:
1 liter of gas = $ 0.78
3.785412 liters = 0.78 * 3.785412
1 gallon = $ 2.95 (Rounding to the nearest cent)
<u>The cost of gas per gallon in Canada is $ 2.95 (Rounding to the nearest cent)</u>
Answer:
Luca has 55 crayons as 42 + 13 = 55
9 - 8x = 35
subtract 9 from both sides
-8x = 26
divide both sides by -8
x= -26/8
you can simplify this to -13/4
Answer:
The probability is 
Step-by-step explanation:
If she has n distinct password candidates and only one of which will successfully log her into a secure system, the probability that her first first successful login will be on her k-th try is:
If k=1

Because, in her first try she has n possibles options and just one give her a successful login.
If k=2

Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and 1 of that give her a successful login.
If k=3

Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and n-2 that are not correct and after that, she has n-2 possibles options and 1 give her a successful login.
Finally, no matter what is the value of k, the probability that her first successful login will be (exactly) on her k-th try is 1/n
