Intermediate Algebra Assignment for 5/20 (Test Warning!)

We did some more work with Linear vs Exponential models today, and the homework is more of the same. We’ll start reviewing the unit as a whole tomorrow, with our planned Unit 9 test on Friday, May 24th

Intermediate Algebra Assignment for 5/17

Today’s assignment is about deciding whether a linear or exponential model is most appropriate for a set of data. The short version is make a scatterplot and examine the picture. If it looks straight, use a linear model. If it looks curved, use an exponential one.

More of the same today as yesterday, only this time working with exponential regression instead of linear.

Intermediate Algebra Assignment for 5/15

Not all linear or exponential relationships are as perfectly defined as we’ve seen. Sometimes the fit of a line or a curve is a bit more approximate, and finding the equation for these functions is a bit more tricky. Fortunately, your calculator provides you with a helpful tool in doing just this: Regression. The instructions for getting your calculator to do this are in today’s notes. They’re a little tricky (lots of button pushes), but pretty straightforward.

More with linear and exponential models today, specifically with interpreting what the parameters (slope, y-intercept, growth rate) mean in the context of the scenario they model.

The big takeaway is this: for both linear and exponential models, the y-intercept is the starting point or initial value. For a linear function, the slope is the unit rate of change – the change in whatever y measures per one unit increase of whatever x measures. For an exponential function, the value of b always represents the growth or decay rate – typically expressed as a percent. You’ll need to set b = 1 + r or b = 1 – r, then solve for r to get the percent change.

Don’t forget to bring your Chromebook and calculator every day for the rest of this week!

We’re in the last phase of Unit 9, which starts off by reviewing the difference between linear and exponential equations and deriving the formulas for these equations from a table of values.

AP Statistics Assignment for Week of 5/13

Your AP exam is on Thursday, in the afternoon. Between now and then, what we do for review is largely up to you. I’ll have some ideas here and there, but I’ll expect you to ask questions and guide what we do for these last few days.

Tonight, you should take a look at the AP Exam tips on pages 608-610. We’ll do some more review with AP multiple choice questions in class tomorrow, but after that it’s up to you!

Intermediate Algebra Assignment for 5/10

We will be starting the last part of Unit 9 on Monday, some more work with exponential and linear modeling. This will include a review of Linear and Exponential Regression, so you should plan on bringing your calculator and charged Chromebook every day next week.

Today was our quiz, and we have the usual post-quiz homework assignment. Complete one page, your choice, for the homework credit. Complete both pages for an extra point on the quiz.

Intermediate Algebra Assignment for 5/9

I’ve decided to push the quiz a day to give us a little more time to review. Your homework is twofold:

 

Intermediate Algebra Assignment for 5/8

Your second quiz of the unit, on exponential function and compound interest word problems, is tomorrow. You got HW 9.11 – Quiz 2 Review in class today, and that will be collected tomorrow. You can find the answers here.

I also recommend you rewatch some of the lesson videos posted below and/or work on some of the highlighted IXL Modules.

AP Statistics Assignment for 5/8 & 5/9

By Friday, complete the 2014 released Free Response Questions. On Friday, you’ll get into grading groups and score your peers’ responses according to the scoring rubric. Note that this is a different exam from what appears on your review calendar.

This grade will not be counted towards your marking period average. Please do not review the solutions to these problems. Let this be another opportunity to practice the free response section of the exam. Spend no more than 1.5 hours, and use no resources other than your calculator and formula sheet.

Write all of your answers on blank sheets of paper. More than one solution per page is fine; we’ll staple them together in class. But please make it neat! Your peers will be reviewing your work!

AP Statistics Assignment for 5/7

We reviewed the binomial and geometric probability models today, along with sampling distribution models for proportions and for means. Tonight, please do the following

In addition, I’d recommend you look at section 10 from your review book.

8th period: Please watch this video to introduce the big idea behind today’s lesson (late in the video, the term “gradient” refers to the slope of the line tangent to the curve at a point), then watch this video from 14:30 to 18:15 for some examples of how to use this formula. Your homework will be the same as below.


We expanded on compound interest today, extending the concept to the idea of “compounding continuously,” which in turn led us to the fascinating mathematical constant of e. If you’re interested in learning more about e, click the link!
