Answer:
It will take 3.2 hours for 8 inches of snow to fall.
Step-by-step explanation:
You can solve this be going "backwards".
You have 2.5 inches of snow falling per hour for x hours until you get 8 inches of snow, which can be represented like this:
2.5x=8 From here you being to solve by isolating x on one side of the equation. You would divide both sides by 2.5 to do this
2.5x=8
/2.5 /2.5
8 divided by 2.5 is 3.2 and you then get
x=3.2
It takes 3.2 hours for 8 inches of snow to fall
thirty-two million, two thousand, eight
Y=-1/2x-3
You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b
Answer:
11/35
Step-by-step explanation:
There are a total of 21 people in the group, 12 of whom are not Democrats. The members are selected in succession. The probability the first member isn't a Democrat is 12/21.
Now there are 20 people remaining, 11 of who are not Democrats. So the probability the second member isn't a Democrat is 11/20.
The total probability is (12/21) (11/20) = 11/35
