Describe Le Chatelier's principle and discuss how it can be used to understand the problem created when Flint changed their treated water source from Lake Huron to the Flint River.

Briefly argue why it is untrue to say that public-key encryption is more secure than conventional encryption.

What role do technology and timing play in realizing advantages from the data asset? Are advantages based on analytics and modeling potentially sustainable? Why or why not?

Part A:  The number of cars arriving at a self-service gasoline station during the last 50 hours of operation are as follows:

The following random numbers have been generated: 44, 30, 26, 09, 49, 13, 33, 89, 13, 37. Simulate 10 hours of arrivals at this station. What is the average number of arrivals during this period?

Part B:  The time between arrivals at a drive-through window of a fast-food restaurant follows the distribution given below. The service time distribution is also given in the table in the right column. Use the random numbers provided to simulate the activity of the first five arrivals. Assume that the window opens at 11:00 a.m. and the first arrival is after this, based on the first interarrival time generated.

Random numbers for arrivals: 14, 74, 27, 03

Random numbers for service times: 88, 32, 36, 24

6.32 LAB: Exact change - functions

Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies.

Ex: If the input is:

0 

or less, the output is:

no change

Ex: If the input is:

45

the output is:

1 quarter
2 dimes 

Your program must define and call the following function. Positions 0-4 of coinVals should contain the number of dollars, quarters, dimes, nickels, and pennies, respectively.
void ExactChange(int userTotal, vector<int>& coinVals)

Suppose your firm is considering two mutually exclusive, required projects with the cash flows shown below. The required rate of return on projects of both of their risk class is 9 percent, and that the maximum allowable payback and discounted payback statistic for the projects are 2 and 3 years, respectively.

Use the PI decision rule to evaluate these projects; accept the project with the higher PI value.

• accept both A and B

• accept A, reject B

• accept neither A nor B

• reject A, accept B

Suppose your firm is considering two mutually exclusive, required projects with the cash flows shown below. The required rate of return on projects of both of their risk class is 11 percent, and that the maximum allowable payback and discounted payback statistic for the projects are 2 and 3 years, respectively.

Use the payback decision rule to evaluate these projects; which one(s) should it be accepted or rejected?

• accept both A and B

• reject A, accept B

• accept A, reject B

• accept neither A nor B

1. Is a three to five day old embryo deserving of moral respect and protection?

2. If unwanted embryos in fertility clinics are going to be destroyed anyway, why not harvest their stem cells first and reap the potential benefits?

3. Should pro-life organizations such as Catholic health care institutions, participate in research on ESC lines if doing so would not entail the destruction of any more embryos?

4. If we don't use these unwanted embryos in fertility clinics for research, how do we respond to those patients, now suffering from diseases, who might have benefited from such research?

In an experiment, 11.5 grams of NO₂ gas are placed in a container at 30.00°C and 1.26 atm. What is the density of the gas?

Corporate Social Responsibility as a Motivating Force

Whatever their perspective, most people have a cause that they are passionate about. Bitcoin or net
neutrality, sea levels or factory farming—social causes bind us to a larger context or assume a higher
purpose for living better.

So what motivates employees to give their all, work creatively, and be fully engaged? According to CB
Bhattacharya, the Pietro Ferrero Chair in Sustainability at ESMT European School of Management and
Technology in Berlin, Germany, employment engagement, or how positive employees feel about their
current job, was at an all-time low globally in 2016: 13 percent. But not all companies battle such low engagement rates. Unilever employees more than 170,000 workers globally and has an employ
engagement level around 80 percent. How? Bhattacharya credits the success of Unilever, and other
companies with similar engagement levels, to an emphasis on a “sustainable business model.” He
outlines eight steps that companies take to move sustainability and social responsibility from buzzwords
to a company mission capable of motivating employees (Knowledge @ Wharton 2016).
According to Bhattacharya, a company needs to first define what it does and its long-term purpose, and
then reconcile its sustainability goals with its economic goals. With its purpose and goals defined, it can
then educate the workforce on sustainable methods to create knowledge and competence. Champions
for the effort must be found throughout the organization, not just at the top. Competition should be
encouraged among employees to find and embrace new goals. Sustainability should be visible both
within and outside the company. Sustainability should be tied to a higher purpose and foster a sense of
unity not simply among employees, but even with competition at a societal level (Knowledge @ Wharton
2016).

Other companies have made social responsibility an everyday part of what they do. Launched in 2013,
Bombas is the brain child of Randy Goldberg and David Heath. Goldberg and Heath discovered that
socks are the most-requested clothing at homeless shelters. In response, the two entrepreneurs
launched a line of socks that not only “reinvents” the sock (they claim), but also helps those in need. For
each pair of socks purchased, the company donates a pair of socks to someone in need (Mulvey 2017).
According to the company website, “Bombas exists to help solve this problem, to support the homeless
community, and to bring awareness to an under-publicized problem in the United States” (n.p.).
Although the New York–based company is still growing, as of October 2017 Bombas had donated more
than four million pairs of socks (Bombas 2017).

In 2016, the Royal Bank of Scotland (RBS) launched a pilot program called Jump in which employees
participated in challenges on ways to save water and electricity, as well as other sustainability issues. At
the end of the pilot, 95 percent of the employees reported that they felt the program had contributed to
employee engagement, team building, and environmental stability. Given the success of the program, in
2017 it was expanded to all RBS sites and a smartphone app was added to help employees participate in
the challenges (Barton 2017).

Placing a company in a larger context and adding a second, higher purpose than the established
company goals motivates employees to police the company itself to be a better global citizen. Companies
benefit from reduced waste and increased employee engagement. Many companies are successfully
motivating their staff, and working toward more sustainable practices while improving lives directly.
