Preliminary Question-Answer (qa) Questions

--------------------------------------------------------------------------------

There are 2 questions in this document, accompanied by some instructions.

Copy this document into a word processor or text editor.

Answer the two questions posed in this document, inserting your answers, confidence assessments and self-critiques as explained.

•

Solutions are given, but don't look at the solution to a question or problem until you have entered your answer.

•

You will probably find that you can answer many of these questions without writing anything down.

•

It is often helpful to sketch, doodle, jot down ideas, do calculations, organize and test ideas on paper. On those problems where you cannot arrive at an answer 'in your head', is recommended that you work out your solutions on paper.

When appropriate, you will later be encouraged to use a calculator to do any arithmetic you cannot do mentally. However the calculator is not appropriate to the questions that appear on this document. Put the calculator aside and think through these questions.

When you are finished you will submit your work according to the instructions at the end of this document.

--------------------------------------------------------------------------------

It is important that all the information in documents of this nature be submitted, so that all the information ends up posted at your page.

When submitting documents, do not delete anything from the original document. Insert your answers, questions, comments, etc. as indicated, but do not otherwise change the original document.

Question: `q001. If you are earning money at the rate of 8 dollars / hour and work for 4 hours, how much money do you make during this time? Answer in such a way as to explain your reasoning as fully as possible. A solution to this problem appears several lines below, but enter your own solution before you look at the given solution.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: (type in your solution starting in the next line)

8 * 4 = 32

confidence rating #$&*: 3

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

confidence rating #$&*: (Type in a number from 0 to 3, indicating your level of confidence in your solution.

2 means that you are more that 50% confident of your solution, or that you are confident you got at least 50% of the solution

1 means that you think you probably got at least some of the solution correct but don't think you got the whole thing

0 means that you're pretty sure you didn't get anything right)

.............................................

Given Solution: 8 dollars / hour means '8 dollars per hour', indicating that for every hour you work you earn 8 dollars. If you work for 4 hours, then if you earn 8 dollars for every one of those hours you earn 4 * 8 dollars = 32 dollars.
