AP Statistics Assignment for 1/31

In addition to the extra credit logic puzzle (due tomorrow!), please work on Unit 4 practice exam found on pages 439-443, specifically 1-25 odd and question 2 from the free response. We will start on Friday with a review of these questions.

Intermediate Algebra 2 Assignment for 1/30

More work with rational exponents today, with a focus on using them to solve equations. Your homework is HW 5.3 – More Evaluating Rational Exponents. The notes can be found here, and check out this video for more examples on using rational exponents to solve radical equations (though you can stop at around the 5-minute mark, the examples past that are beyond what we do in this class).

We spent some more time evaluating rational exponents today. The homework is HW 5.2 – Evaluating Rational Exponents. You can find the notes from today’s lesson here, and check out this video for some more examples.

Finally, because I want you to be able to work through this chapter without relying on the calculator, we will have a daily Powers Quiz. I will choose 10 powers from the warmup reference sheet you made on Friday. I will ask you to evaluate them without using the calculator in a brief, timed quiz. We will do this every day this week, and only  your highest grade on any one quiz will be the one used in your Unit 5 grade.

AP Statistics Assignment for 1/29

You got the Unit 4 review packet in class today. It contains a list of topics from Unit 4, answers to the textbook review assignment, and additional practice problems. Please come in tomorrow with questions from the unit as we prepare for Wednesday’s test.

If you’re looking for supplemental review materials, Mr. Passer’s notes about Chapter 16 (Geometric and Binomial Probability models) were very clear and well-written, so I recommend reading that. Also, you can find my answers to the Chapter 16 worksheet from Friday here.

Intermediate Algebra 2 Assignment for 1/26

We’ve started a new unit, this one on rules of exponents. Today was a review of pre-existing rules, along with an introduction of some new ones. Your homework is HW 5.1 – Review of Exponent Rules. Review the list of rules here, or check out these videos:

Intermediate Algebra 2 Assignment for 1/18

Your test is tomorrow, Friday. Please do not be absent from this test! If you know you’re not going to be in class tomorrow, please arrange to make up the test earlier in the day. Otherwise, you will have to come in during the following exam week to make up the test.

The final review sheet is here: HW 4.15 – Test Review 2. This will be collected tomorrow. Answers to both review sheets (yesterday’s and today’s) can be found here: Test Review Answers.

Complete this review, read over your notes, and do some IXL work from the modules below, and you should be fine.

AP Statistics Assignment for 1/18

Read pages 418-423, stopping at “The Normal Model to the Rescue!”

From pages 430-432, do exercises 7, 10, 12, 17.

A word about assumptions and conditions…

In order for a model to be valid for a scenario, we must be able to make certain assumptions about that scenario.  They can include the results of individual trials being independent from each other, the number of trials/sample size being large enough for the model to apply, etc.

If it is appropriate to make these assumptions, then go ahead and do it, but if it is not appropriate to make these assumptions, you can still proceed provided certain conditions are satisfied.  These conditions mean that the scenario is “close enough” to allow the model to be valid.

For example, coin flips are independent.  There is no finite population of coin flips that you are “drawing” a sample from, and so each coin flip’s outcome is independent of the next.  Drawing cards from a deck are not independent, as the deck is finite and the probability of a certain outcome changes with each card that is removed. However, if the population is large enough, or more specifically if the sample is small enough in comparison to the population, then that probability change is very small, small enough to be ignored.

In general, as long as the sample size is less than 10% of the overall population, the probability change isn’t big enough to be worrisome.

Intermediate Algebra 2 Assignment for 1/17

Your Unit 4 test is on Friday, January 19th. This test will be cumulative for the entire chapter, including the work we did with radical expressions in the first half. Today’s homework is HW 4.14 – Test Review 1. Finish this tonight, and work on some of the IXL modules below!

Intermediate Algebra 2 Assignment for 1/16, plus test warning

Our test on Unit 4 will be on Friday, January 19th. Please do not be absent on that day! If you know for some reason that you will be absent on that day, please arrange a time before the 19th to take the test! Otherwise, we will have to schedule a time for you to take the test during exam week!

Our last “new” topic from Unit 4 was a revisitation to the solving of quadratic equations. Recall that the decision to permit the square root of negative numbers was motivated partly by allowing all quadratic equations to have solutions, so today we spent some time talking about how to write/solve these equations. Your homework is HW 4.13 – Solving Quadratics with Nonreal Roots. You can find the notes here and some more examples in this video.

Intermediate Algebra 2 Assignment for 11/12

Just a few more topics before our Unit 4 test on Friday, January 19th. Today’s assignment is HW 4.12 – Rationalizing Imaginary Denominators. As usual, you can find the notes here and a video with some additional examples here (note: you can stop watching this video at the 8-minute mark. The examples he does beyond that point are beyond what we will do in this class).

Intermediate Algebra 2 Assignment for 1/10

Today’s homework is HW 4.10 – Simplifying Square Roots of Negatives, and in particular how imaginary numbers are used to accomplish this goal. You can find the notes here and see some more examples in this videoPLEASE REMEMBER: negative radicands do not multiply. Pull out the i first, before you multiply.
