Intermediate Algebra Assignment for 4/30

We will have a quiz on the first part of the unit (including simplifying expressions with exponents and on sketching the graphs of exponential functions) on Wednesday, May 2nd. We started reviewing for this quiz with a game of survivor.

Intermediate Algebra 2 Assignment for 4/27

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.

We started Unit 9 today, a unit that is partially review and partially new content around exponential functions. Our first lesson used M&Ms to model exponential growth and decay. If you were in class today, you should finish the lab sheet for the activity. If you were not in class today, your homework is HW 9.1 – Investigating Exponential Functions

Your test on Unit 8 will be on Tuesday, April 24. Your first review assignment can be found here.

Also, many of you did not complete the IXL assignment from Thursday night. For shame! Please work on that this weekend. If you are having technical issues, please let me know. Don’t use that as an excuse to blow off this assignment!

Intermediate Algebra 2 Assignment for 4/18

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.

We’ve introduced the last major topic from our unit on Statistics: 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.

Intermediate Algebra 2 Assignment for 4/10

Permutations and combinations tend to be tricky to figure out when you first encounter them, so we spent some more time looking at examples, including a modification to the concept to find arrangements of letters in a word.

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.

Today we discussed an important idea in probability and statistics: determining when events are independent and/or mutually exclusive.

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.
