Read the case study below and answer the questions that follow:
A private investor recently experienced an increase in her profit due to the changing ways of doing business. She would like to investigate the feasibility of hiring a property manager for her mostrecent residential-commercial project in the outskirts of Ghala. All of her other projects concern import & export (e-commerce) and this is the first time that she will be responsible for a construction project.
a. Assume that a marketing portfolio has to be provided to the investor to motivate her to hire a property management firm. The portfolio should include:
i. A brief description of any two (2) bespoke services that can be provided.
ii. An explanation of the how the services provided will add value for her.
iii. An outline of any two pitfalls that she has to be aware of while working with property managers.

The fumigation plume is one of the most environmentally detrimental plume types.
a. Draw a fumigation flume, along with its corresponding graph, i.e., elevation (m) vs temperature (°C).
b. Why does fumigation plume occur? Discuss on the basis of atmospheric temperature and stability

Two types of flaws may occur during the fabrication of steel beams: (1) the inclusions of small quantity of foreign matter “slag”; and (2) the existence of microscopic cracks. It has been found by careful laboratory investigation that for a certain size I-beam from a given fabricator, the mean distance between microscopic cracks is 40 feet along the beam, whereas the slag inclusions exist with an average rate of four (4) per 100 ft. of the beam. Each of these types of flaws follow a Poisson process.
a) For a 20-ft I-beam, what is the chance of finding exactly two microscopic cracks in the beam?
b) For the beam in a, what is the probability of finding one or more slag inclusions?
c) If a 20-ft beam contained more than two flaws, it would be rejected. What is the probability of rejecting a 20-ft beam?
d) Four 20-ft beams were supplied to a contractor by this fabricator last year. Assume that the flaw conditions among the four beams are statistically independent. What is the probability that only one beam had been rejected?

8. When fossil fuel is burned, many different types of carbon-based molecules can be emitted. Of all carbon-based emissions, carbon dioxide is the best-case scenario given what will occur to the other carbon-based emissions. Explain why you agree or disagree with the previous statement and the consequence of this fact. (SHORT ESSAY)

Skyward Construction has just purchased a new D9 bulldozer for
$675,000. The annual insurance is $7,000. The annual maintenance
cost for the first 4 years is $12,500, at which time the equipment
is given a major overhaul for $75,000. For the next 4 years the
annual maintenance cost is $22,500. At that time the piece has a
salvage value of $100,000. Draw the cash flow diagram. What is the
present value of the investment? What is the EUAC? Assume a 5.%
annual inflation rate.
