Assume that it is now January 1, 2001 and you will need $1,000 on January 1, 2005. Your bank compounds interest rate at an 8 per cent annual rate.
I. How much must you deposit of January 1, 2002, have a balance of $1,000 on January 1, 2005?
II. If you want to make equal payments on each January 1 from 2002 through 2005 to accumulate the $1,000, how large must each of the 4 payments be?
III. If your father were to offer either to make the payments calculated in (b) or to give you a lump sum of $750 on January 1, 2002, which would you choose?
IV. If you have only $750 on January 1, 2002, what interest rate, compounded annually would you have to earn to have the necessary $1,000 on January 1, 2005?
V. To help you reach you $1,000 goal, your father offers to give you $400 on January 1, 2002. You will get a part-time job and make 6 additional payments of equal amounts each 6 months thereafter. If all of this money is deposited in a bank which pays 8 per cent, compounded semiannually, how large must each of the 6 payments be?
VI. What is the effective annual rate being paid by the bank in part v.?

Since the outbreak of the global pandemic, known as, COVID-19, government officials, researchers, businesses, community leaders, and private citizens have been puzzled by the size and the speed of the spread of this virus as well as the death toll. Efforts are directed to widespread testing of symptomatic of COVID-19. The outcome is one test positive or negative. Data at the parish or county level will become available at some point including age, ethnicity, lack or presence of personal protective equipment, social distancing, underlying health issues, etc. Please respond to the following questions:
Q.1.1. Which model will be appropriate to represent the outcome of the COVID-19 testing [positive or negative]?
Q.1.2. Discuss the statistic(s) that can be employed to present the results to the general public.

Air flows over a 4 meter long flat plate at a velocity of 8 m/s. Using a spreadsheet, calculate the boundary layer thickness and wall shear stress at 0.1 meter intervals along the plate. Do not plot the wall shear stress at x=0. Use a transition Reynolds number of 5 x 10^5 . (You will need to calculate Rex at each location to determine if the laminar or turbulent correlations should be used.) Generate a spreadsheet table that includes columns for the x location, Reynolds number, boundary layer thickness, and wall shear stress. Also include the exact transition location in the x column. At the transition location, calculate both the laminar and turbulent correlations and include both values in your plot. (The solution will have a jump at the transition point.) Plot your results for the boundary layer thickness and wall shear stress on separate plots. Submit a copy of your EXCEL table and the plots you generated. Include a plot title and label the axes with the variable name and units. Use only lines, no symbols, to show your analytical solution.

In the study, it was found that mothers reported more progressive parenting attitudes and modernity than fathers, why might this be the case?
"Authoritarian parenting was associated with lower academic achievement in Australia, China, and the United States, but it was associated with higher academic achievement in Hong Kong. Furthermore, within Australia and the United States, authoritarian parenting was associated with higher academic achievement among parents with low education/low income." Why might this be the case?

What do you think about competitive academic activities, such as spelling bees, focusing on the following questions:
(1) Do spelling bees and other academic competitions encourage or discourage working hard?
(2) What are the effects on self-concept and self-esteem for the few winners and the many losers?
(3) Do these events encourage a mastery orientation, a learned-helpless approach, or both?
(4) What types of comments can teachers make if they want to offer process praise rather than person praise for students’ performance in academic competitions?
(5) Do students think that competitive school activities should be eliminated? Why or why not?
(6) How would you suggest modifying the structure of spelling bees and other competitive academic activities so that they encourage cooperation among children, rather than just competition?
