Changes in demographic outcomes can occur because of changes in within-group rates and/or changes in composition. First, explain what that sentence means. Then take the example of falling rates of death due to heart disease. How might changes in within-group rates account for that outcome? What about changes in composition? Can you think of any way to sort out the effects of changes in within-group rates vs. changes in composition?

For the wave equation, utt = c2uxx, with the following boundary and initial conditions,

u(x, 0) = 0

ut(x, 0) = 0.1x(π − x)

u(0,t) = u(π,t) = 0

(a) Solve the problem using the separation of variables.

(b) Solve the problem using D’Alembert’s solution. Hint: I would suggest doing an odd expansion of ut(x,0) first; the final solution should be exactly like the one in (a).

let R be the region bounded by the line y=0, by the upper part of the circle x2+y2=4, and by the upper part of the circle x2+y2=9. Find the circulation of the force F= ( 5cosx-y3)i+ (x3+ 4x+ 5siny)j around the curve C , where C is the boundary curve of the region R , oriented counterclockwise. Draw the region R precisely, and show the orientation of the curve C by putting arrows on C

Suppose for a random sample of 49 CMU students, the mean amount of time spent eating or drinking per day is 1.58 hours with a S.D. of 0.62 hours!

a. What is the Standard Error of the estimate of the population mean?

b. What is the Margin of Error at a C.L. of 90%?

c. What is the right boundary of the C.I. at a C.L. of 90%?

d. At a 98% C.L., if the researcher wants to limit the error within 0.2 hours range, what size of the sample is needed?

Using the models and theories of either (1) market structure, conduct and performance, (2) game theory or (3) the boundary of the firm, perform a microeconomic analysis of one appropriate economic issue or phenomenon of your choice. Clearly explain your chosen question, method and conclusions. Comment on the link between market structure and performance for your chosen issue.

At t = 0s, the leading edge of a wave (wavelength 1m) is 3m to the left of a boundary. The wave is moving to the right at 1m/s. The transmitted wave has wavelength 3m. (You may draw pictures to help you answer the questions below, but you must explicitly state - in words - the answers to the questions.)

(a)[8 pt(s) ]At t = 5s, where is the leading edge of the transmitted wave? Is the transmitted wave inverted or non-inverted, and why?

Develop a general computer program using MATLAB for the analysis of plane
(2D) frames. You can use Chapter 6 as a reference. The program should be able
to:
a. Analyze a frame subjected to different load types, such as joint load,
member load, and support displacement;
b. Analyze frames with different boundary conditions: pin, roller, and fixed
support;
c. Generate the results including joint displacements, member axial, shear and
moment forces, and reactions

The Cheebles cookie factory changed their recipe. The inspectors took a sample of the new cookies and found that the sample was 42 grams with a standard deviation of 4 grams. the Cheebles CEO specially asked the inspectors to use these statistics to find the lower and upper boundary weighs of 50% of their cookies. What are the Z values of the limits of the limits of the area covering the middle half of the area under the normal curve that the inspectors would use to find this information for the CEO of Cheebles?
