Commutative:
a+b+c=a+c+b
1.3+23.4+3.4=23.4+1.3+3.4
Associative:
(a+b)+c=a+(b+c)
(1.3+3.4)+23.4=1.3+(3.4+23.4)
11x+3y=103 and y=3x+1.
11x+3(3x+1)=103 -----> plug in (3x+1) for y in the first equation. You will want to distribute the 3 to the 3x+1 to get something that looks like:
11x+9x+3=103 ------> now you want to combine like terms
20x+3=103 ---> subtract 3 from both sides
20x=100 ----> divide both sides by 20
x=5
y=3(5)+1 ---> I like to plug in this to the equation that already has y isolated. 3*5 is 15, add 1 and you find that y=16.
(5, 16) will be your final answer (:
Answer:
This is one the situations like "hey ma, I don't know." You should learn to do this yourself and not rely on other digital people. IF I WERE TO HELP YOU, (you should really explain what you need) and the real directions

Answer:
The correct option is d. 0.60
Step-by-step explanation:
Consider the provided information.
At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast.
The coffee being a light roast is 0.15 and the probability of the coffee being a dark roast is 0.25.
Pr(Light roast) = 0.15
Pr(Dark roast) = 0.25
We need to find the probability of the coffee of the day not being a light roast or a dark roast on the next day that Mike visits the coffee shop.
Hence, the correct option is d. 0.60
