Acid rain, rainwater that has a lower-than-normal pH, can have a severe negative impact on the plant and animal life in a region. What are the main components of acid rain? Research the sources of these components and what steps are currently in place to improve the pH of rainwater. Explain why acid rain is considered a regional problem, whereas ozone depletion is considered a global problem. What negative effects of acid rain are observed in your town or region?

Global Airlines randomly chose 10 passengers from today's 9 a.m. Chicago-Tampa trip as part of their customer service programme. Each sampling traveller will be questioned on the services, amenities, and other aspects of the airport. Each passenger received a number when they boarded the aircraft in order to choose the sample. The range of numbers ranged from 001 to 250. What other way could a random sample be selected from the 250 passengers?

John Maynard Keynes was the first to demonstrate how governmental policy may be used to alter total output and avert recessions through economic stabilisation. Describe the state of the global economy at the time Keynes wrote. Describe the state of the American economy now. What initiatives were put forth by the presidential contenders in the 2008 election to avert or reverse a 2008–2009 recession? From John Maynard Keynes' perspective, were the acts taken appropriate? Did they produce the intended results?

According to Global Research News (Mar. 4, 2014), one-fourth of all rough diamonds produced in the world are blood diamonds. (Any diamond that is mined in a war zone - often by children - in order to finance a warlord's activity, an insurgency, or an invading army's effort is considered a blood diamond.) Also, 90% of the world's rough diamonds are processed in Surat, India, and of these diamonds, one-third are blood diamonds. Find the probability that a rough diamond is processed in Surat and is a blood diamond.

Use a graphing calculator or a CAS to plot the graph of each of the following functions on [-1,7]. Determine the coordinates of any global extrema and any inflection points. You should be able to give answers that are accurate to at least one decimal place. (a) $f(x)=x \sqrt{x^2-6 x+40}$ (b) $f(x)=\sqrt{|x|}\left(x^2-6 x+40\right)$ (c) $f(x)=\sqrt{x^2-6 x+40} /(x-2)$ (d) $f(x)=\sin \left[\left(x^2-6 x+40\right) / 6\right]$

Gallup found in 2013 that 58% of Americans worry a great deal or a fair amount about global warming, up from 55% in 2012. Results for this Gallup poll were based on telephone interviews performed on March $7-10,2013$, with a random sample of 1022 adults, aged 18 and older, living in the United States. Does the increase from 2012 to 2013 show a substantial increase in concern?

c) Perform the test and find the $P$-value.

Look through a recent issue of The Economist. Each issue includes a section titled "economic indicators." This section contains the most recent growth figures for a large number of countries. According to the most recent data, which countries in the world are growing the fastest? Which countries are growing the slowest around the world? Look through The Economist's stories to see if you can find an explanation for the pattern you've noticed. Write a brief essay about current global economic conditions.

A recent PwC Supply Global Chain survey indicated that companies that acknowledge the supply chain as a strategic asset achieve 70 percent higher performance. The “Leaders” in the survey point to next-generation supply chains, which are fast, flexible, and responsive. They are more concerned with skills that separate a company from the crowd: 51 percent say differentiating capabilities is the real key to success. What additional information would you want to know about the survey before you accepted the results of the study?

The table gives the gross world product, G, which measures global output of goods and services. If t is in years since 1950, the regression line for these data is $G=3.543+0.734 t$.

$$\begin{array}{|c|ccccccc|} \hline \text { Year } & {1950} & {1960} & {1970} & {1980} & {1990} & {2000} \\ \hline G & {6.4} & {10.0} & {16.3} & {23.6} & {31.9} & {43.2} \\ \hline \end{array}$$

Plot the data and the regression line on the same axes. Does the line fit the data well?
