### Assignments for Friday, 11/30/2012

__Algebra II:__

__Statistics:__

Today we’ll learn about
transforming the equations for parabolas between standard form and vertex
form. Each form provides different types
of information; we’ll learn the advantages and disadvantages of each.

Do 5-3: 17-20, 27-32, 36-37,
42, 57, 74

Each Friday from now to
Christmas break, you will be watching a holiday movie. On the Monday following, you will take a
trivia quiz, whose results we will use to perform a statistical analysis. Today's feature is "Elf."

Today we applied parabolic functions to more real-life problems and even MORE problems!

Have a safe and enjoyable Thanksgiving break!

Students used linear and quadratic regression to model data and make predictions for various story problems.

Worksheet found here: 5-1 Modeling Data with Linear and Quadratic Equations

Answers found here: 5-1 Modeling Data with Linear and Quadratic Equations ANSWERS

In this episode of Numb3rs, Don knows that his actions have led to the
death of a protected witness, and assumes that he therefore made the wrong
decision about whether or not to interact with her. To try to find out the
truth, Charlie uses a __Classification
And Regression Tree (CART) Analysis__ to try to analyze Don's motivations
and determine whether he was actually at fault. This statistical method has
applications in a variety of fields, including in medicine.
