1.1. Kalvin always has cereal for breakfast. He likes Cocoa Blast cereal, but his mother wants him to eat Heath Nut Flakes at least some mornings.Kalvin and his mother agree to leave the cereal problem to chance. Each morning Kalvin tosses a coin. If the coin lands on heads, he will have Cocoa Blast. If the coin lands on tails, he will have Heath Nut Flakes.
1.2. Kalvin wants to find something else to toss that will give him a better chance of eating his favorite cereal each morning. He wonders if a paper cup would be a good thing to toss.
Because Kalvin wants to eat Cocoa Blast more of the time, he needs to determine if the cup lands in one position more often than another. If so, he will ask to toss a paper cup instead of a coin.
1. Kalvin tosses a paper cup once a day for a year to determine his breakfast cereal. Use your results from problem 1.2 to determine the following.
a. How many times do you expect the cup to land on its side? On one of its ends?
b. How many times do you expect Kalvin to eat Cocoa Blast in a month? In a year? Explain.
The cup lands on its side 80%(0.8) of the time, while it lands on its edges 20%(0.2) of the time, Heads on a coin would be equal to the cup landing on its side, and landing on its edges would be equal to a coin landing on tails.

So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:

For every 1ft in the original, the model used 2in
1ft:2in
There are 12inches in a foot, so we could also write the ratio as
12in:2in
12/2=6 So the model is 6X smaller than the original
The length of the original was 9ft
L=9ft
The width of the original was 4ft
W=4ft
The height of the original is 6ft
H=6ft
The volume of the original is:
V=L*W*H
V=9*6*4=216ft³
Now lets find the dimensions of the model...
If the length of the original was 9 feet we just divide that number by 6 to find the length of the model.
9/6= 1 1/3 ft
The length of the model is 1 1/3ft or 16in
If the width of the original was 4 feet we just divide that number by 6 to find the width of the model.
4/6= 2/3 ft
The width of the model is 2/3ft or 8in
If the height of the original was 6 feet we just divide that number by 6 to find the height of the model.
6/6=1ft
The height of the model is 1ft or 12 inches
The volume of the model is...
V=l*w*h=16in*8in*12in=1536in³

Step-by-step explanation:For every 1ft in the original, the model used 2in
