Midterm Grades

Today I returned your midterms. Overall they were very good. We spent part of class going over the answers and correcting them. Be sure you understand all of these concepts.

Have a great weekend!

Coming up:
- We will start looking specifically at quadratics on Monday

Midterm Review

Today we went over the homework from Monday and reviewed for the Midterm. Be sure that you are studying your old tests and correcting any mistakes you made.

Coming up:
- Midterm this THURSDAY!!! We have moved it from the original date (Friday).

When is your Midterm now? (sorry for the date changes but this should benefit everyone)

Problem Solving

We started today by reviewing the problems you had for homework dealing with the different types of variation. Be sure you know how to find the regression line using your calculator and understand what it is used for (and how to use it).

I also handed back your tests from last week. Overall they were very good! Another job well done. Be sure to review ALL of your test material for the midterm this Friday!

We also looked at some Problem Solving situations using the material from the last chapter. You should have problems 1-7 (skip 3 and 5) done for class tomorrow.

Have a great week!

Coming up:
- Homework: p. 125 #'s 1-7 (skip 3 and 5)
- Midterm this FRIDAY!!!!!!

What is the Regression Line used for in a scatterplot?

Variation

We started the day by looking at the graphs for both our M&M data, as well as the Starbucks data. Make sure you know how to plot data on your calculator, find the regression line, and understand how to put that information back into the context of the problem. This material WILL be on the midterm.

We discussed 4 different types of Variation: Direct, Inverse, Exponential, and Joint. Be sure that you know the equations and standard shape of these relationships. If you still have questions, check out the links to the right.

Have a great weekend!

GO HEELS!!! Check out Late Night With Roy at Tarheelblue.com this weekend

M&M Data

Today you guys split up into groups and took data on 10 fun size bags of M&M's. You should have taken data on several variables including: weight of bag, # of M&M's per bag, # of each color, etc.

In class you completed a set of questions dealing with the graph of the Weight vs. # in each bag, and found the regression line for this data. We will discuss this data tomorrow, and use the Starbucks data to create another plot.

Coming up:
- No Homework for tonight, unless you did not finish your Graph in class
- Midterm next week!

Test (Transformations and Inverse Functions)

Today was your third test!! Hopefully everyone thought they did well! You will get them back as soon as everyone has taken the test.

Coming up:
- Tonight you should rework the problem that was one the board at the end of class
- Be sure you have your Starbucks data with you tomorrow (just the table)
