Prob/Stat May 4: We reviewed simple event probability, complementary events and odds for the quiz on May 6 which covers pp. 19-30 from the book and notes from class. Homework: complete application 24, do a tree diagram of tossing 2 dice and a list of outcomes.
Probability and Statistics April 22: Great job calculating and applying experimental probability, we will move on to theoretical probability on Friday. The quiz on experimental probability will be Tuesday the 28th
Homework: finish Application 10, do Application 7.
Geometry April 21 and 22: We are well into our similarity unit:
55: Solve proportions
56: Word Problems: Solve proportions
57: Similar figures and proportions
Quiz
58: Similar triangles and proportions
59: Word problems: Similar triangles and proportions
60: Side-splitter theorem
Quiz
Test on May 5 and 6
If you are stalled on proportions or word problems, please come for help so that you are ready for your first quiz on April 23 or 24. Translation: you should be on your third practice by now.
Probability and Statistics April 20th: We began the probability portion of the course last class. You should have read pp. 1-6 and have notes from today on some vocabulary we need for our study of experimental probability.
Homework: Finish Application 3 with your own data for #1-5 and the class data for #6. And application 9: your answers can be simplified fractions or percents.
April 20th Plane geometry D block homework: Proportions worksheet.
Probability and Statistics April 6: Last quiz on statistics today.
Homework: # 2-69 on the the worksheet calls for making a time series plot of the Federal minimum wage, include the three data points hand-written in. #2 calls for making a time series plot of the percent of filed lawsuits filed by inmates. (Divide the smaller number by the larger and change the decimal to a percent.)
4 students still need to turn in their projects, they are already late and have lost 10 points. An additional 10 points will be lost if they aren't turned in by tomorrow, Tuesday April 7. Since the project is approximately 20% of your quarter grade, I will need to call home to enlist some help for you to complete it.
Geometry April 3 & 6. Lots of progress on using theorems to identify congruent triangles We will have a quiz tomorrow and Wed. while it's still fresh in your mind, and then continue with proportions.
Probability and Statistics March 31: We used the calculator to check our median-median lines and construct a Line of best fit. No homework except for the project. Please e-mail me if you have any last-minute questions, or I will be in S-6 Wednesday afternoon.
Probability and Statistics March 27: We have learned to construct a robust regression line (median-median line) on our scatterplots for the purpose of making predictions from a set of data.
Homework: App. 34 questions #1-6. Also, the statistics project is due Thursday but will be accepted Friday even though we don't have class.
If you are having trouble with which data to put in the scatter plot, try reading Application 31 questions 3 through 7. Notice that you can try plotting different combinations of 2 columns of data to look for associations. For some of the project applications, it is also possible to use the ratio of 2 columns to generate a third set of data that might show an association or trend.
Plane Geometry March 30-31: On to congruent triangles!
Plane Geometry March 24-27
H block Tuesday and D block Wednesday: Today is the last class before the test on Thursday/Friday.
If you don't complete your spheres practices to get the gold arrow and take the last quiz in class today, you will need to come after school by Wednesday to complete it or you will not get 100% for your classwork grade and you will get a 0 for the 3rd quiz. (We have had LOTS of class time to complete this unit. Most of you are up to date or ahead. If you are behind, it's because you are not putting in the time on homework or not taking and using notes to get the practices correct, or not coming for extra help when you need it.)
Probability and Statistics March 23
We reviewed trend lines and began our study of several fitted lines on scatterplots with the y=x line. Also, we spent time in class to begin the Statistical Analysis projects due on April 2. Most students chose the data set they will use and began planning. Time will be given in class on Wednesday as well as long as it is needed on the project.
Classwork done: Read pg. 111-2 and do #1-7 on page 112-3
