Tonight, please complete the "Powerball and Nickels" worksheet provided in class! This is a short homework...and I'm checking! So do it! The questions are listed below (in case you lost yours or were absent).
Tomorrow in class we'll finally finish our chapter 14 notes...then, we'll do some multiple choice practice. We'll have our chapter 14 vocab quiz on Thursday or Friday (still can't decide), and then we'll be done with chapter 14! Wooo!
See you all tomorrow! Enjoy your Tuesday!
Powerball and Nickels Homework Questions:
- The
diameter of a nickel is .8125 inches
- The
distance from New York to Los Angeles is
2443.79 miles
1.)
Suppose we are going to line up nickels (in a
straight line) directly from NY to LA. How many nickels will we need? (There
are 5,280 feet in a mile).
- Let’s
assume one of those nickels has a big red X on it, and is randomly placed
in the long nickel line from NY to LA.
- Let’s
also assume you are in a plane that flies along the long nickel line, and
your goal is to jump out of the plane (with a parachute)and land with your
big toe on the nickel that has the big red X.
2.)
What is the probability (assuming you will
definitely land on a nickel) that you land on the nickel with the red x?
- POWERBALL
is a lottery where you must match 5 white balls and 1 red “powerball” to
win the jackpot
- The
white balls are numbered 1 – 59
- The
“powerball” is numbered 1 – 35
3.)
What is the probability you match one of the
white balls in the Powerball lotto?
4.)
What is the probability you match the red ball?
5.)
What is the probability you win the Powerball?
6.)
Compare your answers to (2) and (7). What is
more likely—landing on the nickel with the red X or winning the powerball?
