Math 2000 Assignment 10

Spring 2002

Due April 25

Do not wait until the last minute to start the assignment! It’s best to get an early start and work on it in several steps. Do not hesitate to ask for help before the assignment is due! BB’s office hours are on Tuesdays and Thursdays 10:30-11:30 and 12:45-1:30 in Science 130/132 or by arrangement. Dustin’s office hours are on Mondays and Wednesdays 11:30-1:00 in Science 130/132. Email also works at wbriggs@math.cudenver.edu and dstewart@math.cudenver.edu.

• Assignments must be either typed or hand-written neatly; in the latter case, it is safest to work in pencil. You may use a word processor and write equations and calculations by hand.
• Assignments must be on clean sheets of paper (lined paper is often easier), not torn from a notebook.
• Assignments must include all steps that lead to the final answer. Solutions that require discussion must be written in complete sentences with perfect spelling and grammar.

1. We will now learn to count!. Please read Unit 7E of the text.

2. Please do the following exercises. This is a minimum recommended dose of exercises. You should work more exercises if you have not mastered the concepts.

Unit 7E: 4, 6, 8, 12, 14, 21.

Don’t forget this one!! You have a choice of playing one of three lotteries.

• Lottery 1: you must match the numbers on five balls drawn from a barrel with 56 balls
• Lottery 2: you must match the numbers on six balls drawn from a barrel with 40 balls
• Lottery 3: you must match the numbers on seven balls drawn from a barrel with 33 balls

Which lottery offers the best chance of winning the grand prize? Show your work and explain your answer.

Just for Fun:

Place two quarters on a table so they are touching. Carefully roll one quarter, without slipping, around they other quarter until it returns to its original position. How many complete revolutions does the rolling quarter make? Surprised?
