# AP Statistics Assignment for 2/14

Over break, please finish your thinking about the Hershey Kiss drop activity we did in class today.

In addition, work on exercises 38, 43, 44, and 45 from chapter 17 (some more practice with the Central Limit Theorem) and start reading Chapter 18: pages 473-479

Finish reading chapter 17, pages 453-464

From the exercises on pages 468-470, do 29, 35, 36, and 39.

If you would like to explore the simulation apps I used in class, you can find them here and here. Note that the second link requires a browser that works with Java, which Chrome does not support. Try Internet Explorer or Safari. You can also check out this simulator app, which has a variety of built-in populations of data for you to explore!

# InCA Assignment for 2/12, plus Test Warning

**We will have our Unit 4 Test on Friday, February 14.** It will cover the entirety of Unit 4, but will prioritize the content since the quiz (complex numbers, solving equations of various types, and logarithms). **DO NOT BE ABSENT FROM THIS TEST**

The last topic from this unit is an introduction to the concept of logarithms, which is a pretty big part of the full Algebra 2 curriculum, but not one that has a lot of focus for us in InCA.

# InCA Assignment for 2/11

Today’s lesson was about solving equations when the variable is in the exponent. The trick is to get both sides of the equation to be in terms of the same base, which is why having a good familiarity with various powers of bases 2-10 is so useful. Refer to your reference sheet from the start of the unit!

# InCA Assignment for 2/6, plus HW Quiz Warning

We revisited solving quadratic equations today, now with the capability of evaluating negative radicands!

Tomorrow in class, we will have a homework quiz taking problems from assignments 4.10, 4.11, and 4.12

# AP Statistics Assignment for 2/6

We had our Unit 4 test and will do the group redo tomorrow in class. The final wrap up for the unit is to take some time and review everything we’ve done so far using the Unit 4 Practice Exam in the textbook.

By Monday, please complete the odd-numbered multiple choice problems (1-25) and free response question #2 on pages 439-443

# InCA Assignment for 2/5

We finished More work with imaginary numbers today, in particular simplifying expressions that involve multiplying them or with higher powers. We saw in the videos we watched previously that powers of *i* don’t increase like other real numbers, but instead cycle through the numbers 1, *i*, -1, *-i*, and then back to 1 again.

We also discussed briefly how these new numbers work with allowing us to solve previously unsolvable quadratic equations, which we will reinforce tomorrow.

Your Unit 4 Test is **tomorrow**. You got a batch of review materials today, which you can find online here. If you’re interested in reviewing the noted summary of differences between the binomial and geometric models, you can find it here.

I encourage you to work on additional problems from the textbook. I can provide answers on request.

If you have an active IXL account from another class, you could also check out the practice modules in sections X and Y of the PreCalculus section of IXL. Even if you don’t have an account, the system should let you do about 20 problems, which might still be useful!

Our Unit 4 test will be on **Thursday, February 6**. You got a batch of review materials today, which you can find online here.

We’ll have some more time tomorrow for questions. Come prepared!

# InCA Assignment for 2/3

We’ve started the second section of Unit 4, learning about complex and imaginary numbers. This is a new category of number, much like irrational or negative numbers, that mathematicians developed to handle equations that they previously had no ability to solve. We watched two videos to introduce this topic, but I recommend you watch the full story found here.
