Summary:

We took the Midterm Exam today — another practice SAT test.

Congratulations to Austin, Marina, Danielle, and Irene for making 700+ this time! (Kevin and Sarah were not here today). Also, it is so nice to see each student’s progress compared to their pre-test!

 

Homework:

1. Please make corrections to section 1 (we will hand out section 2 when we meet next week).

2. Finish #multiples of 3 on Page 57.

3. Preview Chapter 7: Constructing Models.

 

Errata (SAT Math: The Advanced Guide and Workbook)

Chapter 3 Exponential vs. Linear Growth, #3 (pg. 26): The answer explanation on page 260 has a typo. The rate should be 1 – 0.06 = 0.9410.06=0.94.

Chapter 7 Constructing Models, #1 (pg. 47): The question should read “… and then lays \dfrac{x}{2}2x bricks per hour for 2y2y more hours.”

Chapter 21 Triangles, #14 (pg. 184): The diagram is drawn incorrectly, though it’s hard to tell. The diagram should be drawn so that triangle ABCABC is similar to triangle DEFDEF (and the sides should correspond).

Chapter 23 Trigonometry, #12 (pg. 207): The answer explanation on page 310 has a typo. In quadrant III, sine and cosine are both negatives (not positive).

Chapter 25 Probability, #10 (pg. 223): The first sentence of the question should read “A manufacturer uses two assembly lines to produce refrigerators.”

 

Please make those changes in the textbook 🙂 Thank you! See you all next week!
