Decide whether or not each of the following topics is appropriate for the stated limits, and then write a few sentences to explain why each topic is or is not acceptable. 1. A two-to-three-page paper: A history of animal testing in medical research labs 2. A two-hour final exam: The effectiveness of bilingual education programs 3. A one-hour in-class essay: An interpretation of one of Andy Warhol’s paintings of Campbell’s soup cans 4. An email to your college newspaper: A discussion of your school’s policy on plagiarism

In equation $y''-y=-2\cos t$ determine a particular solution by inspecting the nonhomogeneous differential equations. If a particular solution is not obvious to you, use the method of undetermined coefficients.

Discuss how the concepts of this section support the idea that in studying nonlinear differential equations, we discover both order within chaos and chaos within order.

Shown in the following table are the reading scores of a second-grade class given individualized instruction and the reading scores of a second-grade class given traditional instruction in the same school:

Find the mean and standard deviation for the traditional instruction scores.

State if the possible arrangements represent permutations or combinations, then state the number of possible arrangements. A student chooses at random 4 book from a reading list of 11 books.

Write the vector formulation for the given system of differential equations.

$$x _ { 1 } ^ { \prime } = e ^ { 2 t } x _ { 2 } , x _ { 2 } ^ { \prime } + ( \sin t ) x _ { 1 } = 1.$$

For each of the following differential equations in Problem, apply the method of Frobenius to obtain the solution. $\left(3 x^{2}+x^{3}\right) y^{\prime \prime}-x y^{\prime}+y=0$

The National Claims History (NCH) contains records for $999,645$ Medicare patients who were dis- charged from acute care hospitals in October $2008$. The Department of Health and Human Services performed a detailed audit of adverse medical events on a random sample of $780$ drawn at random without replacement by assigning a random number to each patient on the list and then choosing random integers between $1$ and $999,645$. (a) What kind of sample is this (random, systematic, stratified, cluster)? (b) Is this population effectively infinite?

Find the general solutions of the differential equations. $2 \frac{d^{2} y}{d t^{2}}+5 \frac{d y}{d t}+2 y=0$

(a) Connect: What feelings about Chapman's translation do lines $9$- $14$ convey?
(b) Draw Conclusions: How does the comparison of reading to a journey support these feelings?

In lab you find that a 1-kg rock suspended above water weighs $10 \mathrm{~N}$. When the rock is suspended beneath the surface of the water, the scale reads $8 \mathrm{~N}$. a. What is the buoyant force on the rock? b. If the container of water weighs $10 \mathrm{~N}$ on the weighing scale, what is the scale reading when the rock is suspended beneath the surface of the water? c. What is the scale reading when the rock is released and rests at the bottom of the container?

Find a particular solution, satisfying the initial condition, of each of the following differential equations.

$(y+7) d x+(2 x+y+3) d y=0, y(0)=1$.

What are the mean and standard deviation of the difference Y - X between the readings? (The readings X and Y are independent.)
