A. Well she starts with 24 buns. She ate 1/2 half of a bun leaving 23 1/2 buns left. Then she gave her mother and father a bun each so you do 23 1/2 - 2 which gets you 21 1/2 buns. So the total number of buns that she has left is 21 and 1/2 buns.
The independent variable (the one they want) is the # of hours worked, since that determines the price.

Answer:a) 54/55
b) 100/110
c) 99/110
Step-by-step explanation:
a)Probability of ordering 4= 9/12×3/11×2/10×1/9 = 54/11880
Probability of 4 good units= 4 × 54/11880
= 216/11880
1/55
1-(1/55) = 54/55
b)Probability of 2 good units= 2 × 54/(11880)
= 108/11880
= 1/110
1- (1/110)= 100/110
c) Probability of exactly 2 units not good= 1 -(100/110) =99/110

Answer:
Step-by-step explanation:
Given: 
; find x and y.
Let's start with finding x first. Let's distribute the left side of the equation.
Let's move everything we can to the left side of the equation. Some things will cancel out.
Now, let's move the term that includes 
to the left side of the equation. Everything else should be moved to the right.
Let's get rid of the negative sign in front of by dividing both sides by -1.
To get completely isolated, divide both sides by 
.
Simplify.
Let's solve for y. We will start with the distributed and simplified equation to make it easier.
Now, let's move the term that includes 
to the left side of the equation. Everything else should be moved to the right.
Again, let's get rid of the negative sign in front of the by dividing both sides by -1.
To isolate y, divide both sides by z.
Simplify.
