# AP Statistics Assignment for 5/2

We’ll spend tomorrow discussing the free response questions from the practice exam, and in the meantime you should be working on the 2017 released free response questions. Answers will be posted tomorrow for your review over the weekend.

# Intermediate Algebra Assignment for 5/1

We are in the middle of a lesson on calculating taxes (see this video for a recap of the basic method of calculation, and/or check out the notes here). We’ll finish it up tomorrow with some more examples, but first we need some sample salaries!

Look up a typical yearly pay/salary for **two to three jobs**. The jobs could be anything, but try and make it practical (a job you could reasonably see yourself doing).

For each job, write the job on one side of an index card, and the typical yearly pay/salary on the other. Bring in those cards to class tomorrow, and we’ll work on calculating some more examples.

# AP Statistics Assignment for 5/1

We will have an in-class quiz assignment tomorrow, where I’ll put you in groups and give you an investigative task from a past AP exam to work on. You’ll have the whole period to work on it, but you won’t be allowed to use your notes or text: only your own effort (and the formula sheet).

In preparation, take a look at the Investigative Task section of your review book (Topic 14), then work on questions 1, 3, 6 from problems starting on page 403.

# AP Statistics Assignment for 4/30

We reviewed the Linear Regression t-Test, our test for association in quantitative data. Your homework is:

- Question 5 from the 2011 Free Response
- Question 5 from the 2005 (Form B) Free Response
- Question 6 (part b) from the 2001 Free Response

Please review my answers here *before* class tomorrow so we can more efficiently resolve any lingering questions you may still have, and spend most of the period tomorrow talking about the multiple choice section of the practice AP.

# Intermediate Algebra Assignment for 4/30

After today’s quiz, we have the usual post-quiz homework/extra credit assignment. Complete **one side**, you choice, for a homework credit. Complete **both pages** (and you must show your work!) for extra credit on the quiz.

# Intermediate Algebra Assignment for 4/29

Your first quiz of Unit 9 is tomorrow. Remember that this is a **no calculator** quiz.

# AP Statistics Assignment for 4/25

We’re going to take a short break after today’s practice exam. Do your own review from the Barron’s book, or work on other classwork. We’ll pick things up again next week.

# Intermediate Algebra Assignment for 4/25

Today, we revisited the exponential growth and decay functions we first saw with the M&Ms activity on Wednesday, and we formalized our notation and vocabulary a bit.

If you’re here to watch a lesson video **in class**, you can find it here.

You can also stop watching at around the 7-minute mark, as it goes on to examples we will not do.

# Intermediate Algebra Assignment for 4/23

We debriefed the M&Ms lab from yesterday, then worked on tonight’s homework: HW 9.1 – Investigating Graphs of Exponential Functions. Note that you’ll need your graphing calculator, or an online grapher like Desmos, to do this homework more easily!

# Intermediate Algebra Assignment for 4/22

We’ve started our last unit of the course, a fairly lengthy unit on Exponential Functions.

If you were in class today, you should finish the M&Ms Exponential Growth/Decay Lab Sheet using the data you gathered in class. Be sure to bring your calculator tomorrow for the debrief!

If you *weren’t* in class today, your alternate homework assignment is HW 9.1 – Investigating Graphs of Exponential Functions

# Assignment for Spring Break

It’s spring break. We just finished the long walk from February break to April. When we get back, we’ll only have 8 short weeks before the end of the school year. But you have a week to rest and regroup before we get there. So here’s your assignment for this week:

Stay up until 3am, then sleep in until noon. Read a book. Watch a movie. *Make* a movie with some friends. Go out at night and ponder the stars. Go for a hike in the Cornell Botanic Gardens. Hang out on The Commons with some friends, then each lunch at Waffle Frolic. Plan a day trip to Syracuse, or NYC. Go to the SPCA and pet the cats (or the dogs!). Listen to some music. Start to learn to play an instrument. Do a barrel roll. Watch the first two episodes of *Game of Thrones*. Go play in a trivia game at Kilpatricks or Ithaca Bakery. Go for a run before the sun rises. Go for a walk in Stewart Park. Go say hi to Mr. Noyes at the farmer’s market (he sells flowers!). Do some push ups, or pull ups, or squats. Make dinner for your family. Bake something. Go out and do a Random Act of Kindness for a stranger. Hop on the TCAT and just ride around for an hour. Go to a restaurant and order something you’ve never tried before. If you’re in AP Statistics, work out of your review book (Practice Exam 1 would be a good choice!). Go out and practice some rock balancing. Play a board game. Learn a card trick. Start a YouTube channel. Take some pictures, but don’t show them to anybody. Do your chores. Do someone else’s chores. Talk to someone with different opinions from you. Go to somewhere in Ithaca you’ve never been to before. Whatever you do, enjoy yourself and find some time to relax. Then come back on the 22nd ready to work.

# Intermediate Algebra Assignment for 4/9

Today, we reaffirmed that the Expected Value is a **long-term** average. Meaning the results of a small handful of trials are unlikely to produce the same average as the expected value, however increasing the number of trials will produce averages more in line with what you expect.

Don’t forget that our test on this unit will be on **Thursday, April 11th!**

# AP Statistics Assignment for 4/9

From chapter 26, read pages 715-729 (skip the sections on standard error for predicted values).

From pages 733-735, do exercises 28, 30, 44.

And **bring your review books in tomorrow!**

# Intermediate Algebra Assignment for 4/8, plus Test Warning

We did some more practice with calculating Expected Value today, and the homework is to continue that work.

Our test on this unit will be on **Thursday, April 11th**. If you will not be in school that day, **you must make up the test before you leave**. NO EXCEPTIONS

We are one chapter away from starting our AP Exam review process. For now: read pages 706-715, up to the section on “Standard Error for the Slope”

From the exercises (pages 730-735), do exercises 1, 7, 24, 35

# Intermediate Algebra Assignment for 4/5

We’ve introduced the last major topic from our unit on Probability: the Expected Value. This quantity is a long-term per-trial average, that gives you a way of determining what a typical outcome of a handful of trials should be. This is an important tool in the field of statistics, and will be something you’ll see again in later math classes.
