Mr. McClendon’s Math Emporium

Below is the answer key to test 3.  I hope you feel like you did well on the test!  Thanks to yours truly the last problem on the test had a typo and therefore won’t be counted against you or for you.  Unless you realized that it must have been a typo and corrected it and then proceeded to get the correct answer!

If you come about 15 minutes early to class I will give back your test and answer questions that you may have .  If that doesn’t float your boat, you can stay a few moments after class with questions.  We will be covering 4.5 and parts of 4.6 if possible and I have a quiz to give out (it will be due next Wed.).

Here is an explanation for SGI pages 129 and 130.  These types of problems will be on the test!  This is embedded in Google video.

 Test on Friday!!

As I promised posted below is the answer key to test 2.  If you check out the key and still find that you have a question, post a comment or email me and I will post a video explanation.

 As a heads up for Mondays class, try to search Google for logarithms to find a basic explanation of what they are( don’t worry we are still going to go over them in class if you don’t find much).  Also try to polish up on your exponent properties that are in the book in section P.2 ( the blue box on page 12) or on the bottom of page335.

Here are some exapmle problems for the worksheets I assigned today.

I have Test 2 graded and have the statistics to go along with it. The test scores are 19, 26, 27, 30, 34, 35, 45, 46, 50, 66, 67, 71, 72, 73, 73, 74, 75, 76, 81, 82, 82, 86, 89, 95, 96, 97.  The Average was a 64 with a Standard Deviation of 24.  The Median was 72.5. The First Quartile was  45.25 , the Third Quartile was a 81.75.  Look for a previous posts to see what each value stands for if you are not for sure.

I will pass back the test and post a solutions guide to it but we will not be discussing it in class due to time constrants.  If you have questions about the test please feel free to ask them after or before class.

Our unit 7 test is tomorrow!  This test will cover reflections,(x and y axis, origin, and line y=x) translations, (shifting up, down , left, right) rotations (90 degrees clockwise and anticlockwise, 180 degrees)  and dilations. 

Posted are the answers to the study guide I gave out Monday.

 Remember that you can make a cheat sheet to use on the test from a 3″ by 5″ index card or paper cut to size.    If you have any questions, post a comment or email me at mcclendonmath at gmail dot com.  I spelled it out to avoid spam issues.  I will check the blog and email at around 8 and 11 tonight for questions.  Other than that , have a great day!  

If anyone from first block has questions be ready with them becuase we won’t have anytime to review before becuase of clubs.

Remember tomorrow (3-5-08) is test night!  The first of two notebook checks will be tomorrow as well.  I had promised a video explanation of the quiz 3 but had some technical difficulties so only the first few problems are explained.  If you are having any questions I will try to be at class at about 4:00 to answer questions.  I also found a good site.  It’s like a calculator for solving algebra problems.  Link to QuickMath

I will try to post the homework answer keys tomorrow so stay tuned!

Quiz 3 Answers

Classes have been officially canceled for Wednesday 2-27-08 for the Russell Center.

Our Test II on the tentative schedule will be pushed back to Wednesday 3-5-08. I need you to look thru sections 3.1 and 3.2 and try the examples that follow the homework. We will go over these sections on Monday 3-3-08. Test II will cover sections 2.3 -3.2.

The first of 2 notebook grades will be taken on Wednesday 3-5-08 (the night of test II) . I will be checking it for neat, legible notes, tabbed and in order. Also I will check to see if you have been completing your homework problems (these need to be neat and legible as well). If you have done both to a satisfactory level then you will get full credit. The rubric will be as follows:

Organized-10pts, Legible -10pts, Homework- 10pts.

Please have it organized in such a fashion that I or anyone could easily find your notes or homework for a specific section.

Last Monday we talked about the last part of section 2.5 and covered sections 2.6 and 2.7.  We really don’t have enough time in class to see very many examples of scatter plots.  So you need to make sure that you can do these problems on your calculator.  I will post a worksheet that I have given to a previous class that deals with scatter plots.  The first page is the basic diriections for inputing a scatter plot and finding the linear model or line of best fit.  The second page is just some excercises that you are welcome to try.

It is snowing right now here in Somerset and I am not for sure what the weather will be like tomorrow for class.

As of right now class is still a go.  Watch and listen to see it they officially announce night classes have been canceled.

Remember that quiz 3 is due 2-27-08.
