**Monday/Tuesday 03.11-12.19**

**Unit 6 Test**

**Thursday/Friday 03.07-08.19**

**Topic: Product and Quotient Rules for Logarithms**

**Agenda:**

- Team score (trade and grade) 7.1.1 #2-4 and #7.
- Exponent and Logarithm Properties so far (see notes).
- Begin 7.1.2 #15-17 (15 together) to be completed next Wednesday/Thursday.

**Unit 6 Test is Monday/Tuesday**

**Notes: 03.07.19 period 3**

**Tuesday/Wednesday 03.05-06.19**

**Topic: Patterns to rules with logarithms**

**Agenda:**

- Revised procedure for estimating the lower and upper 5% bounds and margin of error for 90% confidence intervals (average the excluded and included values that are on the boundaries-see class notes).
- Completed, discussed and collected teamwork 7.1 #2-4, 7.
- Worked radical equations (see notes).

**Study guide answers:**#44 a) 0.56, 0.74; b) about 0.65 – 0.09 to 0.75 + 0.09; #54 see class notes; #58a) x = 7, b) x = 2, c) (2, -5), (-1, 4), d) (3.5, 3.5) (1.5, -0.5); #78 will be done in class; #83) x = 7.

**Notes: 03.05.19 INT3 period 3**

**Friday 03.01.19**

**Topic: Logarithms**

**Agenda:**

- Worked through #54 from chapter 6. When estimating the margin using a partial sampling distribution as in this problem, just use the first included value after excluding the lowest 5% and the last included value after excluding the highest 5% as the bounds. Averaging those boundaries in not necessarily any more accurate since the true margin of error is based on a theoretical sampling distribution which you will explore in a more advanced course.
- Begin Unit 7
- 7.1 #1 (review of what we already know about logarithms)
- Begin Teamwork 7.1 #2-4, #7 to be completed and collected in class Tuesday/Wednesday. 20% will be deducted for failure to put first AND last names in upper right corner with date, period and title as well as if graph paper is not used for graphs.
**Unit Test 6 will be March 11/12. See linked notes below for study guide. A full answer key will be posted this weekend for all problems except the Closure section.**

- Friday we will tie up loose ends and begin the next unit which will continue into next week.

**No notes as this was an individual work day; students had choices of the above problems and were expected to use the time wisely to get concepts clarified. This is also a good time to look at grades with Ms. Davies and set up times to make up tests or recover credit if needed.**

**I announced the unit test would be next week, but then was reminded next week is mindfulness week so the test will be given Monday/Tuesday March 11 and 12 instead. A study guide will be posted later this week. We will begin the new unit Friday or next week.**- Wrap-up of Skittles activity. Our mean proportion was 0.1984 which was very close to the true population value of 0.20. The middle 90% of our samples fell between 0.12 and 0.28 which gives a margin of error of 0.08 or 8%.

________________________________________________________________________________

**CREDIT RECOVERY POLICY FOR TESTS ONLY (NOT QUIZZES)-PLEASE READ**

Anyone who scores a 70% or higher on a unit test may recover half credit on what was deducted on the test if and only if you demonstrate that you have made a substantial attempt at every homework assigned for the unit. This generally means 70% completion prior to scheduling credit recovery.

Once the above condition is met, you must come in and personally go through every missed problem with Davies to receive half credit back. This means, for example, if you scored an 80% on the test, you can recover 10% which is half of the 20% that you missed.

Those who score below a 70% must retake a shorter, modified version of the unit test and pass it with a 70%. Once this is done, you may come in and recover credit for a maximum of 85%.

Anyone who did not complete 70% of the problems was given and X for exempt. The remaining students will see one column in the gradebook with your actual score that you would have gotten had this not been a completion credit AND a balance column with points entered that make the two columns 10/10 for all non exempt people. Below is a copy of an exemplary paper and a full solution key. Students should check all answers and come in for help if needed.
- We will finish teamwork 1.4 and a write-up for #50-53 will be collected. 1 write up per group. Full graphs of the original two functions and the resulting combined function(s) for each of #50-52 are expected. One graph per problem is fine. More details given in class notes.
- New seats (we will change about once every two weeks.
- OPEN NOTE QUIZ #1
