A Detroit Lions football player kicks a football at an angle of 30º and a velocity of 20
meters per second. How high will the ball go (in meters from the ground)?
5.1
In a desperate attempt to get Juliet's attention, Romeo (who is 6 foot tall) throws a
rock from 1 foot above his head at an angle of 45º with a velocity of 22 meters per
second. Assuming that the rock hits the center of the window when it has reached it's
highest point, how high is the window (the center of the window, in meters)?
If Juliet, who just caught a glimpse of Romeo picking up the rock, excitedly ran to the
window and opened it 2 seconds after Romeo threw the rock, would the rock hit the
window or Juliet?

(Poisson distribution) Depending on the color of car you purchase, you may be at a
higher risk for getting a speeding ticket. For Porsche's, a black car typically gets 1.4
speeding tickets, a white car typically gets 1.2 speeding tickets, and a red car typically
gets 3.2 speeding tickets over a year period. If you purchased a red Porsche, what's the
probability of getting exactly one speeding ticket?

A company that makes toy Elmo dolls has a chief inspector named Vrisken. In three
hours, an average of 2 (two) crates of dolls are rejected because they contain more
than 4 randomly inspected faulty dolls (bad smell, discolored, doesn't speak, swears,
etc...). What is the probability of less than 2 crates of Elmo dolls being rejected in a
three-hour period? (Assume that this plant operates 24 hours per day, 7 days per

In C#, you can simulate rolling two dice by selecting a random number between 1 and
6 to represent each die roll and then adding them together to get the dice total. Let's
EGR 1400
, EGR 1400
say that we developed a program to do this and we rolled the pair of dice 50 times and
recorded the results of each roll on a sheet of paper. Instead of using two die
separately and totaling them (which would result in a total between 2 and 12), can we
just select one random number between 2 and 12 and achieve the same experimental
results for the 50 rolls as rolling two die and adding them?
a.
No, it's not possible to get the same experimental results with one random number
b.
Yes, using the same scaling as before
c.
Yes, if the Visual C# code is written to scale the single random number between 2 and
12
d.
Yes, if the random number is selected using myRand.Next(2,13);
