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.

  • Homework: HW 9.3 – Exponential Growth and Decay
  • Notes
  • Lesson video – This video refers to a specialized version of the exponential function formula we discussed on the notes, where there is a specific % increase or decrease, but the overall content is the same. You can also stop watching at around the 7-minute mark, as it goes on to examples we will not do.

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 4/10

Your test on Unit 8 is tomorrow. You were given two review sheets in class today. Only the first three pages, marked “HW 8.14 – Test Review 1” is due tomorrow. However, if you complete the entire review, that will be worth a bonus HW credit. Review the lesson videos posted below, or work on some IXL practice modules if you’re looking for some additional practice.

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!

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’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.

We’re starting in on the second part of the unit today, about Probability Models. These are ways of listing/organizing all the outcomes of a random trial and their, often unequal, probabilities. This will be the basis for one of the most useful tools in statistics: the expected value.

The next part of the “counting” part of this unit is understanding the difference between two common patterns of counting: permutations and combinations. In brief, permutations are used to count the number of arrangements of objects, specifically when order matters like with ranked lists, unique assignments, or sequences. Combinations are used to count the number of groups of objects, specifically when order doesn’t matter like with committees or batches.

We did some more work with the counting principle today, using it in a variety of applications. The trick is to carefully sort out the number of choices you have to make and the number of options you have for each choice.

We started our second-to-last unit today, about tools of probability. Probability is all about chances and odds, determining how likely various events are to occur. We’ve started with some very basic ideas of probability, but we will quickly move to some more complicated and nuanced applications.
