...? Yemen **Problems** Desalination and Vapor Compression Desalination refers to the processes used to remove salt and other mineral salts from saline water (Micale, Cipollina, & Rizzuti, 2009). Saline water gets desalinated in order to make water that is fresh for human and animal used. The modern process of desalination aims at developing cost effective ways of water provision to the people along the coast. It is viewed as a rainfall independent source of water. The vapor – compression desalination process refers to the process used to distill water. This distillation process involves the evaporation of saline or sea water by the application of heat obtained from compressed vapor. The compression of vapor to be used in the desalination process...

...Math **Problems** The standard equation of ellipse is: (x-h)2 a2 = (y-k)2 b2 Because the center of the Ellipse is at the origin, h and k equals to 0.
Because major axis lies on the x-axis, a equals to 1048ft/2 = 524 ft.
Because minor axis lies on the y-axis, b equals to 898ft/2 = 449 ft.
Therefore, the equation of the Ellipse looks like:
(x)2 / 5242 = (y)2 / 4492
2.
In order to find the principal and the rate, a system of two equations should be solved. One equation describes the return of the household before the change in principal and interest rate, the other - after the change, as shown below:
P * (1 + r) = P + 7.5
(P + 25) * (1+ r - 0.01) = P +25 +7.5,
where P is the initial investment and r is the initial rate (in decimal numbers...

...Statistics **Problems** 21. What is sampling error? Could the value of the sampling error be zero? If it were zero,what would this mean? Sampling error is the error in the statistical figures that are obtained by using a representative sample of a population rather than examining the entire population. It is a measure of the differences between the sample selected and the whole population which are caused solely due to the selected units. In other words, it is a measure of the preciseness of the results obtained using the sample population.
Yes, the sampling error can be equal to zero. In this case, it will mean that the sample selected is an ideal representation of the entire population and the characteristics observed in the sample...

... of the of the of the Probability Birthday **Problem** The Birthday **Problem** is applicable in a scenario where n numbers of people are gathered together in a room. The chances of at least two of the gathered people of having their birthday on the same date needs to be assessed. For this purpose the probability of at least two people having the same birthday needs to be calculated.
There may be a number of variations when considering the situations at hand. However, in order to keep the calculations simple enough, the possibilities of their birthdays lying in a leap year and that of the two people having same birthdays being twins etc. have been eliminated. Having done so it may be proposed that in reality there exists a possibility...

...Math **Problems** Math **Problems** Q The target capital structure for QM Industries is 36% common stock, 8% preferred stock, and 56% debt. If the cost of common equity for firm 17.4%, the cost of preferred stock is 10.1%, the before-tax cost of debt is 7.4%, and the firm’s tax rate is 35%, what is QM’s weighted average cost of capital (WACC)?
(Joshi, 2003)
Where:
Re = cost of equity = 17.4
Rd = cost of debt = 56
E = market value of the firms equity = 35
D = market value of the firms debt = 8
V = E + D = 43
E/V = percentage of financing that is equity = 10.1/43
D/V = percentage of financing that is debt = 7.4/43 (
WACC = (17.4/43)*10.1 + (7.4/43)*56*(1 – 1/8)
4.0870 + 9.6372*(1- 0.125) = 4.0870 + 7.05255 = 12. 520%
