Here is an example of the kind of calculation you need to do to determine a specified linear-to-linear rational function.
Answers to the first midterm exam are here.
UPDATE: these answers have been updated due to an error (problem 1 of version B).
Here are the stats from the first midterm exam:
n = 153
minimum=2
1st quartile = 18
median = 25
3rd quartile = 31
maximum = 40 (1 person)
Here are some rough guidelines for translating your exam score into a 4.0-scale grade. This is only approximate; basically this is what your grade would be if I had to assign grades now based just on this exam.
| ≥37 | 4.0 |
| 33 | 3.5 |
| 28 | 3.0 |
| 24 | 2.5 |
| 21 | 2.0 |
| 17 | 1.5 |
| 14 | 1.0 |
| ≤12 | 0.0,/td> |
If you got a score of 20 or less, you definitely have a lot of work cut out for you if you intend to pass this course with a 2.5. I recommend coming to office hours to discuss whether or not you can recover from this exam, and if so, what you need to do.
Here is a review sheet for the first midterm exam.
The answer in the textbook for 7.11 is incorrect. The correct answer is that the radius of the circular part of the window should be 24/(4+Pi) feet, which is about 3.36059492 feet.
I have changed the homework schedule slightly: problem 4.12 is no longer due this week. It will be due next week. Please don't turn it in this week.
I will give some suggestions for solving it in lecture on Wednesday.
