Lesson starter question

This question is to be solved during class tomorrow and I am expecting to see a response posted in the comment post from all students. You may answer in pairs if access to macs is a problem. You must indicate this in your answer using initals. You may use calculators but must show your calculations in your answer. This is a good habit for your tests and exams.

A furniture salesperson gets paid a $185 retainer each week as well as receiving 1.5% commission on sales. If the salesperson sells $11,680 worth of furniture in one week, what is their income for that week?

networks

Below are the notes for the networks topic in 2AB. This needs to be completed in your own time and you need to make sure you understand the systematic approach to shortest path. These are the questions that most students can do in the exams.

Good Luck in your exams

Good luck and study hard over this week for your exams. Some of you need to perform well in this set!!
Start with the topics you mostly get and then work through the ones you don't
READ THE PAPER lots of times!!!! MAKE A  PLAN during reading time
DO THE EASY ONES FIRST - at least you are getting marks on the board
RECOGNISE SOME QUESTIONS FEEL LIKE LOTTERY GUESSES - but you have got to be in it to win it - sometimes one mark is better than none.

Statistics Central Tendency

Today we covered manipulating mean to solve questions. One key feature before calculating any of the questions is to find the total of the scores in all cases. This information is usually invaluable in
a) finding missing scores
b) calculating required scores
c) calculating overall (combined) means
d) calculating new means following changes

This is not an exhaustive list however it covers most situations that occur in 2AB MAT course.
