VCE General MathematicsPractice Examination 9

This paper covers

• Data analysis: five-number summary and 1.5 x IQR outlier fences, normal distribution (z-scores, 68-95-99.7% rule), least squares regression (slope/intercept interpretation, prediction, residuals, coefficient of determination), seasonal indices, deseasonalising and trend forecasting
• Recursion and financial modelling: flat-rate and unit-cost depreciation recurrences, compound interest and effective annual rate, reducing-balance loan amortisation (balance, interest split, term via Finance Solver), perpetuities and annuity lifetimes
• Matrices: matrix product modelling and order, determinant and inverse of a 2x2 for simultaneous equations, transition matrices S(n+1) = T.S(n), steady state, and the rule S(n+1) = T.S(n) + B
• Networks and decision mathematics: degree sum and Eulerian trails, minimum spanning tree (Prim/Kruskal), shortest path, max-flow min-cut, and project scheduling (EST/LST, float, critical path, crashing)

Students are permitted to bring into the examination the materials normally allowed for this subject. Answer all questions in the spaces provided.
