. Every Tuesday afternoon during the school year, a certain university brought in a visiting speaker to present a lecture on some topic of current interest. On the day after the fourth lecture of the year, a random sample 250 students was selected from the student body at the university, and each of these students was asked how many of the four lectures they had attended. The counts for each combination of number of lectures and classification are given in the table below. number of lectures attended 0 1 2 3 4 freshman 14 19 20 4 13 classification sophomore 10 16 27 6 11 junior 15 15 17 4 9 senior 19 8 6 5 12 Suppose that an student is selected at random from this group. Let A denote the event that the selected student is a freshman, B denote the event that the selected student attended 3 lectures.

a) Calculate P(A), P(B), and P(A ∩ B).

b) Calculate both P(A | B) and P(B | A), and explain, in context, what each of these probabilities represents.

c) Calculate the probability that the selected student attended at least 2 lectures.

d) If the selected student attended at least 2 lectures, what is the probability that he or she is a junior?

All of us use electronic devices and may replace them from time to time. Some people have been raising the alarm about disposal of these products.

1. What happens to electronic devices that are discarded by consumers? These are tangible physical products. Research this topic to find out where exactly the old computers, tablets, cell phones etc go to. Provide references for your answer. Your response should not be “I threw it in the garbage”, you need to track what happens to the garbage. Are these products bio-degradable? Will they leak chemicals that affect the environment?
2. A related issue is product design. Look up Apple Sales of its iPhone X and other models. Some reports note that iPhone6 etc have worked so well that consumers have been using them for several years and do not see the need to “upgrade” – that is, throw away the old phone and get a new one. While that may not be great for Apple, it might be great for the environment! Should companies design electronic products to last longer? Discuss.

. The following quote is from Mallet J (2006) What does Drosophila genetics tell us about speciation? Trends in Ecology & Evolution 21:386-393

“Studies [in] Drosophila have given insight into the genetic changes that result in reproductive isolation. Here, I survey some extraordinary and important advances in Drosophila speciation research. However, ‘reproductive isolation’ is not the same as ‘speciation’, and this Drosophila work has resulted in a lopsided view of speciation.”

Focus in on the last sentence in this quote and answer the following questions:

a. What is speciation? (4 points)

b. What is reproductive isolation? (4 points)

c. Define species according to the Biological Species Concept (BSC). (4 points)

d. Given the BSC, what does the author mean that speciation and reproductive isolation are not synonymous? (4 points)

e. In any event, species concepts are difficult to deal with. The definitions we have for species do not often work for all species. Give an example of how the Biological Species Concept “breaks down” in some cases. (4 points)

1) We be certain the EM wave we receive from space tell us all about the composition and the source temperature why, or why not?  How the location and dynamics of celestial objects affect the observation of space?

2) Explain the process of star’s birth, burning fuel and death, main sequence, and relationship between star colors, their age and their size, black body curve, black hole,  event horizon, quasar, super massive black holes, emission region, and energy released analyses.

This is the question from US History 1 ( DISCUSSION) need about 250-300 words

1. Could the Civil War have been avoided? Was western expansion inevitable? How did one event contribute to the other?

b) Due to severe negative demand shock, US real GDP plummeted from is potential level of $900 billion to $800 billion, so the economy is new in a recession. Suppose the government plans to use expansionary fiscal polices to get the economy out of the recession.

i. Suppose the government wants to cut taxes. Obtain the tax multiplier, and determaine how much of tax cut would be needed.

ii. Suppose the government wants to increase  government spending multiplier, and determine how much of an increase in government spending be needed.

iii. Suppose the government wants to cut taxes and increase government spending. If the size of a tax cut is $20 billion, how much of an increase in government spending would be needed?

Harry Jones owed $20,000 in property taxes. He received a check from Investments R US in the amount of $20,000. He wrote on the back of the check "Payable to Seminole County Property Tax and sent it with a letter explaining that he was paying his taxes.   The County placed a lien on Harry's property for nonpayment. Harry objected because he had paid his taxes. Using IRAC determine who is correct.

Talk about the US Gross domestic product in first quarter of 2019.Why did It drop from 2018 last quarter. Write your normative or value judgement point of view on how the economy seems to be taken.Will we see a turnaround in the upcoming quarters for this year?

Within the global environment there is much discussion regarding moving from US GAAP (Generally Accepted Accounting Principles) to IFRS (International Financial Reporting Standards). We know that corporations are global now more than ever, which results in a diverse group of professional accountants worldwide working together for a common goal, which is to report information for both internal and external users. This diversity does result in variations in practice however the principles and guiding rules and regulations proposed under IFRS will allow for uniformity on a global basis. This move to IFRS from GAAP is not yet finalized however much debated.

Prepare a PowerPoint presentation with a minimum of 7 slides with an abstract for references and a reference slide.

• Articulate the positions on moving from US GAAP to IFRS.
• Build an argument in an influential way to include but not limited to a discussion on the similarities and differences between GAAP and IFRS specifically around the potential effects on the stockholder’s equity section of the Balance Sheet.
• Articulate at minimum three advantages and disadvantages of adopting IFRS specific to the Stockholder’s Equity section of the Balance Sheet.
