Earnings before interest and taxes, ebit, are projected to be $14,300 if economic conditions are normal. If there is strong expansion in the economy, then ebit will be 20 percent higher. If there is a recession, then ebit will be 35 percent lower. The company is considering a $33,900 debt issue with an interest rate of 6 percent. The proceeds will be used to repurchase shares of stock. There are currently 7,500 shares outstanding. Ignore taxes for this problem. what was the name of the collection of texts composed around 500 bce which includes more than 1000 poems a) An object is auctioned. There are two rational (risk neutral) buyers, each attaching a private value (not known to their opponent or the seller) to the object: 10 and 20 euros, respectively. Each bidder assumes that the valuation of the opponent is a random variable that is uniformly distributed in the interval [0,20]. What revenue will the seller expect to earn when the object is auctioned in an English auction? Buyers indicate their willingness to continue bidding (e.g. keep their hand up) or can exit (e.g take their hand down). At what price will the buyer with the lower valuation take his hand down? What is the expected profit of the winner of the auction? b) Using the same information as in a), suppose the seller decides to auction the object in a Dutch auction. Explain what will now be the expected revenue, assuming that the auction starts at a price that is higher than 20 euros. c) What happens to the bidding if bidders in the Dutch auction are risk averse? And in the English auction? Find the equation of the line tangent to the graph of f(x) = x - 4x +3 at x=1. Assume that f is a one-to-one function. If f(4)=7, find f1(7) In 1976, tuition was 1935$ a year and there was a 2.50$ minimum wage in California (8676$ and 11.37$ when adjusted to 2020 dollars). In 2020 tuition was 21337$ a year with 13$ minimum wage..What is the average rate of change in tuition .when adjusted for inflation?.What is the average rate of change in the minimum wage when adjusted for inflation?.How many hours would someone have to work on minimum wage to pay tuition in 1976 vs 2020?.If tuition had not changed, how many hours would someone have to work on present day minimum wage?.If we were to graph tuition and minimum wage, would these constitute a function?.If not, then why?.If so, what would the domain be and possible outputs? Give an example of a value not in the domain and another that is not in the range. The mean'score on a set of 25 tests is 75 a. What ' is the sum of all the 25 test scores? - b. Suppose 'two more 'students:take the 'test and score 92 and 95 . What is the new mean? Let A=104121313. Let Mi denote the (i,j)-submatrix of A. Fill in the blanks: M2I=( M33=(1 M12=(1) 5electa bark to theut an answer Is violet has a high frequency? Simplify the expression. Write the result using positive exponents only. Assume that all bases are no (p^(4)p)/(p^(-4)) What is the average number of students per section in the Clever demo district whose data you can access via our. API using the "DEMO_TOKEN" API token? Notes / Hints - Our API explorer mentions a few other test API tokens, e.g. "TEST_TOKEN". Don't use those for this exercise. Stick to "DEMO_TOKEN" or you may end up with a different answer than the one we're expecting. - The Data API in particular should come in handy. - Clever API queries can return large numbers of results. To improve performance, the Clever API paginates, meaning that it returns chunks of data at a time. By default, it returns 100 records at a time. The demo district of interest has 379 sections, so using only one 100-record page of data will give you an incomplete answer. You can use the "limit" parameter to change the number of records returned at a time. - Round your answer to the nearest whole number. Keep in mind that many programming languages perform integer division (in which the fractional part is discarded) on integers so convert to floating point numbers if necessary. Which two categories represent a classification of all lipids based on their molecular structure?chiral and achiralhydrolyzable and nonhydrolyzablesynthetic and naturalcatalyzed and uncatalyzedcyclic and acyclic When implementing new technologies to support the virtual team, describe the steps project managers should carefully follow to avoid impacting the productivity of the project team.2.
