In this problem, you'll look at the nonlinear system (dx)/(dt)=y-2-x (dy)/(dt)=x^(2)-y (a) Do a qualitative phase plane analysis of the system. That is, sketch all nullclines, and clearly indicate the equilibrium points of the system. Use arrows to give the orientation on nullclines, as well as in each region. Note: Make your picture really big, as you'll be drawing on it more in the next part. (b) This system has two equilibrium points. For each equilibrium point, find the eigenvalues of the Jacobian. If the eigenvalues are real, also find the eigenvectors. Use this information to sketch approximate trajectories near each equilibrium point on your picture from (a). (c) Is each equilibrium point stable or not? 1. In this problem,you'll look at the nonlinear system (dx =y-2-x dt dy dt a) Do a qualitative phase plane analysis of the system.

A class is taking a multiple choice exam. There are questions and possible answers for each question where exactly one answer is correct. How many different ways are there to answer all the questions on the exam? Correct Use the information above and below to determine the probabilities. Enter your answers as percents rounded to four decimal places. A student who didn't study randomly guessed on each question. a) What is the probability the student got all of the answers correct? Correct % b) What is the probability the student got all of the answers wrong? % c) What is the probability

This exercise is based on the following list of top DVD rentals (based on revenue) for the weekend ending November 6, 2011. Title Rank Captain America: The First Avenger 1 Bad Teacher 2 Fast Five 3 Cars 2 4 Trespass 5 Bridesmaids 6 Zookeeper 7 Transformers: Dark of the Moon 8 Scream 9 Thor 10 Rather than studying for math, you and your buddies decide to get together for a marathon movie-watching, popcorn-guzzling event on Saturday night. You decide to watch six movies selected at random from the above list. (a) How many sets of six movies are possible? sets (b) Your best friends, the Lara twins, refuse to see Bridesmaids and also insist that at least one of Captain America or Thor be among the movies selected. How many of the possible groups of six will satisfy the twins? groups (c) Comparing the answers in parts (a) and (b), would you say that the Lara twins are more likely than not to be satisfied with your random selection? They are less likely than not to be satisfied. They are more likely than not to be satisfied.
