We began the semester with an interdisciplinary approach that combined the fields of geometry, visualization, art, history, philosophy and physics, in the

More recently we applied the reasoned strategies that mathematics illustrates as a powerful tools that give us surprising strength for analyzing and conquering life's issues in the finance and statistics segments. We have engaged in creative inquiry methods all throughout this class. My hope is that you will take these skills with you and find it helpful to apply them to your own lives in the future.

You'll receive the numerical data, writing, and computer use designators for your work in this class (all Math 1010s must satisfy the three designators). Math 1010s look very much alike in a lot of ways but we differed slightly by taking the interdisciplinary and thematically linked approach throughout the course, for example, by combining financial mathematics with political science and history in the Ben Franklin project.

- Use the loan payment and interest formulas to determine how much
a customer will save - ie calculate the monthly payment assuming an
8% interest loan of $20,000 compounded monthly for 3 years and then
calculate the interest of the life of the loan - this interest is the
amount the customer would save in the "Keep America Rolling" program.

- Often customers are offered a 0% loan or a cash rebate instead.

## Statistics

To recognize misrepresentations of studies and statistical data in the real world by understanding statistical techniques and satisfy the numerical data designator.### Stock Update

- Take out your stock packet and
do another
stock update
and show it to me so that I can check it off on your sheet.
Recall that the stock market is unpredictable in the short
term, but, in the past,
over the LONG TERM, stocks that don't go out of business
have historically performed better than
savings accounts.
The stock sheet has additional updates listed so that you can check
it again over the long term (after the semester is over) if you like.
### Various Perspectives Using Statistics

We have seen that the media often misrepresents statistics, and that one must dig deeply to fully understand the (often contradictory) issues involved.

#### Flu

For example I searched with

2000 "number of deaths" influenza "united states"

to find out that there were**91,871 deaths**from influenza and pneumonia (which sometimes results from influenza) in the United States in 2000. I also found that there were**94,800,000 flu/pneumonia cases**that year.

Some webpages state that since the late 1940s, the flu vaccine has been the best way to prevent influenza or lessen its severity and that in many years the vaccine prevents over 90% of the influenza/pneumonia deaths. I was surprised by these statistics since I didn't realize that so many people died from complications of the flu. I then looked up the population of the United States via a search with

"census 2000" "total population" "United States",

and obtained**281,421,906 people in the United States**.

One statistic is that the

# deaths from the flu / total population of the united states = 91,871 / 281,421,906 = 3.26...E-4 (E-4 is scientific notation meaning that I go 4 decimal places over to the left - ie .000326...) = .0326%. The is the percentage of the United States population that dies from influenza and pneumonia each year.

Try this on your calculator and make sure you understand before moving on.

There are also other perspectives to examine:

- What is the percentage of cases of flu out of the total
population of the United States? SHOW WORK.

- What is the risk of dying from the flu
(as a percentage) once you already have it?
Calculate this
by taking the number of deaths, dividing by the number of
cases and then turning this into a percentage.
SHOW WORK.

- What are some risks or problems with the flu vaccine?

## What is Mathematics?

We have examined this theme and have also looked at many examples of different kinds of math and some applications of mathematics to real-life, along with the diverse ways that people succeed in math. Here are some readings for use in your personal reflection:

**In addition, prepare to share something in class tomorrow on each of these readings - take notes on what you plan to share.**

"Keep America Rolling Program" 0%

I found out that GM cancelled the program at one point, but brought it back again, and that the loan was often for 3 years. Let's assume that the loan would have compounded monthly at 8%. In the "Keep America Rolling" program, these 3 year loans charge 0% over the 3 years.

Monthly Payment =

Loan (rate/12) |
