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

Sixty-six reading students were randomly assigned to be taught using one of three teaching methods. One method is called Basal and uses textbooks that are organized to develop reading skills. Another method is called DRTA (Directed Reading Thinking Activity) and is a comprehension strategy that guides students in asking questions about a text, making predictions, and then reading to confirm or refute their predictions. The third method, which is called Strat, uses different strategies. The test scores are given in the box. Test the hypothesis that reading method affects test scores using a significance level of 0.05. Show all four steps. Do not do post hoc tests. Assume Normality.

The five "W" questions are useful when reading other types of publications besides literature. Work with a partner to make a list of them.

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

A transducer is modeled with a current source Is and a parallel resistance $R_{s}$. The current at the terminals of the source is measured to be 9.975 mA when an ammeter with an internal resistance of $20 \mathrm{~\Omega}$ is used. (a) If adding a $2 \mathrm{~k \Omega}$ resistor across the source terminals causes the ammeter reading to fall to 9.876 mA, calculate Is and $R_{s}$. (b) What will the ammeter reading be if the resistance between the source terminals is changed to $4 \mathrm{~k \Omega}$?

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?

Describe the benefits of computer-integrated manufacturing operations.

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.

Read Child of the Slums and answer the following questions: How was Susie Rocco’s life in the late 1800s similar to and different from your life? How have industrial growth and technological advancements changed New York since this time? To what extent did reform movements address the problems facing Americans such as Susie Rocco? How would a historian research and write the history of an individual such as Susie Rocco? Why did reform-minded journalists, such as Jacob Riis, use children in their writing and photographs? Was it effective?

Economists have argued that globalization is here to stay and that society needs to adapt to this process or it will be left behind. Historically, four groups have done the most to bring about globalization: traders, preachers, adventurers, and warriors. Although the motives for these groups—to profit, convert, learn, or conquer—have usually been selfish, the overall impact of their actions has been to bring about greater integration and interdependence of nations of the world. Put this view of history into the context of today’s globalization and explain why you agree or disagree

Why is computer modeling used in biological studies?

Use the methods of this section to solve the following differential equations. Compare computer solutions and reconcile differences. $x^{2} d y+\left(y^{2}-x y\right) d x=0$

During the early evolutionary history of the vertebrates, a primordial globin gene was duplicated to form the $\alpha$- and $\beta$-globin genes. The rate of evolution of the polypeptides encoded by these duplicate genes has been estimated to be about $0.9$ amino acid substitutions per site every billion years. By comparing the human $\alpha$- and $\beta$-globins, the average number of amino acid substitutions per site has been estimated to be $0.800$. From this estimate, calculate when the duplication event that produced the $\alpha$- and $\beta$-globin genes must have occurred.
