Inverse Problems

2nd block asked for more problems practicing finding the inverse of a rational function.  This website has a link to some good problems to practice.  Click on the link: Inverse Rational Functions Worksheet

Rational Equations

Here's a page I found with some Power Point slides discussing rational equations.  Looks pretty neat!

More Graphing Practice!

Students in 1st block this morning asked for more graphing practice for rational functions.  This page has 10 more graphs.  There are two graphs with holes.  The answers are at the end.

Off on another tangent...

The unwritten bonus question on the next quiz (Friday for Math IV; Monday for Acc III) is "When is Mr. Lewis's birthday?"  You will need to write next to the answer where you saw this question...

More Rational Function Graphing Practice

Here's a nice website to practice graphing.  If you do it, practice # 1, 7, 9, 11, 15, 23, 25, & 27.

http://hotmath.com/help/gt/genericalg2/section_7_1.html

You will see that you can check your answers.





























Bring these answers, and work, on your own paper by Friday, 11/8/2013, to receive some bonus points, but don't tell anyone....  This applies to all Mr. Lewis's classes (now and in the immediate future...).

Excel Sheet

When I opened the Google Doc of the Excel page at home, it had this "=_xlfn.NORM.INV(RAND(),65,5)" in cell A1. When I deleted the "_xlfn." and the "." in between NORM and INV, it worked fine.

This is what A1 should have in it: =NORMINV(RAND(),65,5)
B1 should look like this: =A1-1.96*5/SQRT(30)
C1 should look like B1 except with a plus.

Of course, this is for a normal distribution, or for a means question. Remember, if you have a proportion, then the function was BININV or BINOMINV, I think.

Again, email or Tweet your questions.

Random Normal Distribution Example

Here is a Google Drive link to the example Excel sheet I showed in 1st block this morning.

To generate the random numbers I used NORMINV(RAND ( ), 65, 5).  I made up a mean of 65 and a standard deviation of 5.  Then I dragged down 100 cells.

To build the confidence intervals, I went to cell B1, typed in an equals sign, clicked on cell A1, then did a minus, 1.96 * my standard deviation, and then divided by SQRT (n).  

If you hold the cursor over any of the cells in Row 1 you will see what I typed in.

Email or Tweet me if you have questions.  Math IV projects are due Monday.
