URGENT!!!!! PLEASE ANSWER THE FULL QUESTION AND PROVIDE VALID SOLUTION, I WILL DO UPVOTE A consumer has non-human wealth equal to $100,000. They earn $40,000 this year and expects their salary to increase by 5% in real terms each year for the following two years. They will then retire. The real interest rate is equal to 0% and is expected to remain at 0% in the future. Labour income is taxed at a rate of 25%. (15)What is this consumer’s human wealth? (3) What is their total wealth? (2)If they expect to live for seven more years after retiring and want their consumption to remain the same (in real terms) every year from now on, how much can they consume this year? (5)If they received a bonus of $20,000 in the current year only, with all future salary payments remaining as stated earlier, by how much could they increase consumption now and in the future? Suppose now that, at retirement, social security will start paying benefits each year equal to 60% of this consumer’s earnings during their last working year. Assume that benefits are not taxed. How much can they consume this year and still maintain constant consumption over their lifetime? (5)

QUESTION 14 Let a max-heap be represented by the following array of size 12 (with indices from 0 to 11). 85, 73, 51, 42, 58, 49, 16, 36, 17, 29, 14, 22 Show the contents of the array after the SECOND phase of Heapsort, that is after the two largests keys have been moved to their final correct position, and the remaining 10 keys have been "re-heapified". Your answer should be a list of 12 numbers, separated by commas, with NO BLANK SPACES or any other keystrokes.

Orville, the robot juggler, drops balls quite often when its battery is low. In previous tests, it has been determined that the probability that it will drop ball when its battery is low is 0.9. Whereas when its battery is not low, the probability that it drops a ball is only 0.01. The battery was recharged not s long ago, and our best guess (before looking at Orville’s latest juggling record) is that the probability that the battery is low is 0.1. A robot observe with a somewhat unreliable vision system, reports that Orville dropped a ball. The reliability of the observer is given by the following probabilities: P(observer says that Orville drops | Orville does drop) = 0.9 P(observer says that Orville drops | Orville doesn’t drop) = 0.2 The Bayesian network for modeling this problem is as follows. Battery is Low (L) -> Orville drops ball (D) -> Observe ball dropped (O) A. The probability P(O = false|D = true), that is, the conditional probability that not observing ball dropped given Orville drops ball, is %. B. The probability P(L = true, O = true), that is, the joint probability that batter is low and observing ball dropped is %. C. The probability P(O = true), that is, the probability of observing all dropped is %. D. The probability P(L = true|O = true), that is, the probability the battery is low given that the observer reports a ball dropped, is %. (NOTE: The percentage sign already is provided. If the number you want to enter is a decimal number, keep only 2 digits after the decimal point. Do use round up/down whenever necessary. For example, if the number you want to enter is 64.35832, enter 64.36)
