Joey is one of several winners who shared a lottery ticket. There are three plans offered to receive the after-tax proceeds.a. Plan 1: $100,000 now.b. Plan 2: $15,000 per year for 8 years beginning 1 year from now.c. Plan 3: $45,000 now, another $45,000 four years from now, and a final$45,000 eight years from now.Joey, a quite conservative person financially, plans to invest all of the proceeds as he receives them. He expects to make a real return of 6% per year. Use the 8-year time frame and an average inflation of 4% per year to determine which plan provides the best deal.

Economics

Wild Wear makes clothing, rain gear, and sleeping bags for hikers and other outdoor enthusiasts. The company began when Myrtle Kelly began sewing pile jackets that her husband Ray sold on college campuses. It now employs almost five hundred people organized into traditional divisions such as marketing, manufacturing, and research and development.
Recently it became apparent that although Wild Wear’s balance sheet appeared healthy, the company was stagnant. Everyone seemed to work hard, and the company’s products seldom flopped. Yet Wild Wear seemed to have developed a “me too” posture, bringing new products to market a season or a full year after competitors.

The Kellys, who still run the company, pored over performance appraisals looking for the weak points that might be holding the company back. But it seemed that the human resources department had been doing its work. R&D was coming up with a respectable number of new products, the manufacturing facility was modern and efficient, and the marketing tactics often won praise from customers.
Baffled, the Kellys called a meeting of middle-level managers, hoping they could provide some answers they had missed. They were shocked when they noticed that the managers were introducing themselves as they came in and sat down. People who had been working in the same company for years had never even met! The meeting began with this observation, and for ninety minutes the Kellys sat back and listened to the problems their managers raised.
It became clear that in the attempt to grow from a family operation into a larger company, the Kellys had assumed the two needed to be very different. When they started out, the two of them handled all aspects of the business. Ray would hear from a customer that backpackers really needed a certain product. He would pass the idea on to Myrtle and order the materials she needed, and within a few weeks he would offer the product to the delighted customer. As the company grew, the Kellys began to worry about their lack of formal business training and hired professionals to run each division and set up appropriate rules and procedures.
What they had created, the middle managers informed them, was a number of very efficient, productive divisions that might as well have been separate companies. The R&D people might come up with a new breathable fabric for rain gear, only to find that production had just begun making a new rainwear line out of the old fabric and that marketing was turning all its attention to selling the big inventory of sleeping bags. Each division did the best it could with the information it had, but that information was very incomplete. Products progressed linearly from one division to the next, but it always seemed as though an idea that had been ahead of its time did not yield a product until the time had passed.
To remedy the problem, the Kellys decided to call in a management consultant to review and assess the organization and make a recommendation for moving forward. You are that consultant.

Finance

The manufacturer of a product that a variable cost of $2.50 per unit and total fixed cost of $125,000 wants to determine the level of output necessary to avoid losses.

a. what level of sales is necessary to break, even if the product is sold for $4.25? what will be the manufacturer’s profit or loss on the sales of 1000,00 units?

b.If fixed costs rise to $175,000, what is the new level of sales necessary to break even?

c.If variable cost decline to $2.25 per unit, what is the new level of sales necessary to break even?

d. If fixed cost were to increase to $17,000, while variable cost declined to $2.25 per unit, what is the new break-even level of sales?

e. If a major proportion of fixed costs were noncahs (depreciation), would failure to achieve the break-even level of sales imply that the firm cannot pay its current obligation as they come due? Suppose $100,000 of the above fixed cost $125,000 werre depreciation expense. what level of sales would be the cash break-even level of sales?

please can you give each detail.

In a doubly linked list, each node can point to the previous node as well as to the next node. Figure 4-10 shows a doubly linked list and its head pointer. Define a class DoublyLinkedBag using C++ that implements the ADT bag by using a doubly linked list as shown in Figure 4-10.

In a doubly linked list, each node can point to the previous node as well as to the next node....

[Hint: you need to define a class to represent a node in a doubly linked list by modifying the node class we used for linked base implementation of ADT Bag]

Requirement:

+ Create the header DLinkedBag.h to implemented ADT Bag.

+ Use the following program to test your ADT Bag implemented by doubly linked list.

Statistics

A study was conducted of 90 adult male patients following a new treatment for congestive heart failure. One of the variables measured on the patients was the increase in exercise capacity (in minutes) over a 4-week treatment period. The previous treatment regime had produced an average increase of 2 minutes. The researchers wanted to evaluate whether the new treatment had increased the average exercise time compared to the previous treatment. The data yielded a sample average of 2.17 and a standard deviation of 1.05.

Sample mean (x) = 2.17

Satandrad Deviation (s) = 1.05

Population mean (M) = 2

Sample size (n) = 90

a) Carryout an appropriate hypothesis test achieve their goal (Use p-value approach). You may use a 5% significance level to draw a conclusion.

2. A synchronous sequential circuit has a numerical input in the form of two bits (X1X2). The circuit remembers the last input and when a new input arrives, compares the new input to the previous input. The output of the circuit (Y1Y2) is determined as: a) – If (new input = previous input), then YAY2 = 11 b) – If (new input > previous input), then Y1Y2 = 10 c) – If (new input < previous input), then Y1Y2 = 01 Derive the state table (10 points), and find the expressions for the D type flip-flop inputs and the outputs (5 points) and draw the circuit schematics (5 points).
