A construction company has an expenditure rate of E'(x)=e^(0.17 x) dollars per day on a particular paving job and an income rate of I'(x)=116.2 - e^(.17x) dollars per day on the same​ job, where x is the number of days from the start of the job. The​ company's profit on that job will equal total income less total expenditures. Profit will be maximized if the job ends at the optimum​ time, which is the point where the two curves meet. (a) Find the optimum number of days for the job to last. ​(b) Find the total income for the optimum number of days. ​(c) Find the total expenditures for the optimum number of days. ​(d) Find the maximum profit for the job.

Different types of beers have different ingredients, flavors, and alcohol amounts. Two popular beers (beer style) in the US are the American Pale Ale and the American IPA. The IPAs tend to have a stronger flavor and come in a variety of colors whereas the Pale Ales tend to be lighter in flavor and in color. Using a statistical package, test to determine if the mean alcohol by volume (abv) for the American IPA is the same as the mean alcohol by volume for the American Pale Ale. Assumptions: • The samples are independent of each other (one is IPA beers and the other is Pale Ale beers). • A random sample of 424 IPAs and a random sample of 245 Pale Ales are taken. • The population standard deviations are unknown for each sample and are assumed unequal.1. Conduct the appropriate hypothesis test using the following steps.a) Determine the null and alternative hypotheses. (2 points)b) Identify the appropriate test statistic and compute its value. Note- Use the Data Analysis toolPak to conduct the test statistics. Please show your output.c) Determine the critical value. (2 points)d) Determine the P-value. (2 points)e) Make a decision to reject or fail to reject H0. (2 points) Reject H0f) State the conclusion in terms of the original problem. (2 points) American IPA and American Pale Ale do not have the same mean alcohol by volume. The IPA is 0.0645 whereas the Pale Ale is 0.0547.2. Calculate the 95% confidence interval for the difference between the two proportions. Does this confidence interval support your results from the hypothesis test? Why or why not? (4 points)

Looking Up At Leaves (1966) Barbara Howes No one need feel alone looking up at leaves. There are such depths to them, withdrawal, welcomes, A fragile tumult on the way to sky This great trunk holds apart two hemispheres We lie between. . . .Like water lilies Leaves fall, rise, waver, echoing On their blue pool, whispering under the sun; While in this shade, under our hands the brown Tough roots seek down, lily roots searching Down through their pool of earth to an equal depth. Constant as water lilies we lie still, Our breathing like the lapping of pond water, Balanced between reflection and reflection. Questions 1. How can a tumult be fragile (see line 3)? 2. What does Howes mean when she says the tree's trunk holds apart two hemispheres? Is the word being used literally or figuratively? 3. Does the last line have more than one literal meaning? (A double entendre)

Iridium is a substance found only in asteroids and other space objects. This graph shows the amount of Iridium found in different sediment layers of Earth. They are marked off into 17 sections representing time. Iridium Levels graph shows Iridium levels in sediment layers. Beginning at sediment layer 1, iridium levels remain between 0 and 5, jumping to a level of 23 between layers 5 and 6, and decreasing to near starting levels at layers 14 through 17. What most likely happened in sediment layer 5? A massive volcano erupted, causing global warming and lava flow, which in turn caused mass extinction. More iridium was produced by space objects and dumped by local factories. A massive dust cloud formed, causing global cooling and a lack of sunshine. This in turn caused a lack of plants and a mass extinction. Fewer impacts lead to a drop in iridium levels and a mass extinction caused by a lack of sunshine.

Flip-flops remain a popular footwear option. Demand for flip-flops is D(p) = 24 - P/2, and the supply function is S(p) = P/2. In equilibrium, the price will be $ , and pairs of flip-flops will be sold. Use the straight-line tool to graph the inverse supply and demand curves below, and then use the point tool to plot the equilibrium point. Use the label tool to label this point "Equilibrium."
