Given the income determination model: 1) Y = C + I$_o$ + G$_o$ + X$_o$ - Z; 2) C = C$_o$ + bY; 3) Z = Z$_o$ + zY where X = exports, Z = imports, and a zero subscript indicates an exogenously fixed variable, a) Express the system of equations as both general and specific implicit functions b) Express in matrix form the total derivatives of both the general and the specific functions with respect to exports X$_o$ c) Find and sign: 1) $\frac{\partial Y}{\partial X_o}$; 2) $\frac{\partial C}{\partial X_o}$; and 3) $\frac{\partial Z}{\partial X_o}$

A municipality has developed a linear equation that relates maximum hour demand (observed in a given year) to minimum hour pressure in the system, such that P = P$_o$ - aQ, where 0 ? Q ? 6000 ML per day where P = minimum hour pressure in the system (in kPa); Q = maximum hour flow in the system (in ML per day); a = coefficient (a = 0.0833 kPa / ML per day); P$_o$ = pressure in the system when there is no flow (P$_o$ = 500 kPa). The maximum hour flow, Q, observed in any give year follows an exponential distribution with mean of ? = 950 ML per day, such that f$_o$(Q) = ? exp(-?Q), where ? = 1 / ?, and 0 ? Q ? 6000 ML per day a) Use derived probability theory to find the probability density function (PDF) of minimum hour pressure, P. b) Use the derived PDF in a) to calculate the probability that the minimum hour pressure in the system will be equal to or below 300 kPa. c) Use the derived PDF in a) to calculate the minimum hour pressure P' in the system with a return period of 100 years. In other words, calculate P' such that Prob[P ? P'] = 1/100.
