Answer:
2.86%
Step-by-step explanation:
assuming there is no replacement
There is a total of 6 envelopes
Since the question is asking for red, then green, then red, order is very important
The probability of a red is 3/7
Since we have selected 1 envelope, there are only 6 total envelopes left so the probability of a green is 1/6
Then we need a red again
Since we have selected 2 envelopes, one of which is red, there are only 5 total envelopes and 2 red envelopes so the probability of a red is 2/5
Now we multiply all of these so 3/7x1/6x2/5 = .02857142857
To find the percentage, you multiply by 100 so 2.857142857
Im pretty sure they want you to estimate it so 2.86% is what I would put but it depends on your teacher

Hope this helps:)
the y value is one ? just insert the 0 into the x which would make the 54 disappear and leave you with y=1
A square has 4 sides that are all the same length so 12.8 divided by 4 is 3.2 so each side 3.2 m
Answer:
They paid $67.45 altogether.
Step-by-step explanation:
First off, we need to set up the problem, I like to do percentage problems like this:
x/58.65 = 15/100
Cross Multiply
100x=58.65x15
When you multiply 58.65 and 15 you get 879.75
Divide
Now we have to divide 879.75 by 100 because 100x=879.75
879.75 divided by 100 is 8.80
So now we know that they paid $8.80 just for the tip.
Add
Now all we have to do is add 8.80 to 58.65
58.65 plus 8.80 is 67.45
The Kerwoods paid $67.45 altogether.
