VCE General MathematicsPractice Examination 16

This paper covers

• Data analysis: normal distribution and z-scores (68-95-99.7), boxplot outlier test, least-squares regression with CAS (slope/intercept interpretation, prediction, residual, r and coefficient of determination), seasonal indices, deseasonalising and trend forecasting
• Recursion and financial modelling: flat-rate, unit-cost and reducing-balance depreciation as recurrence relations, reducing-balance loan amortisation (interest/principal split), Finance Solver for repayments and total interest, annuity duration and perpetuity condition
• Matrices: order and matrix product with interpretation, determinant and inverse of a 2x2 to solve simultaneous equations, transition matrices (interpretation, state matrices, steady state, two-step transitions), the rule S(n+1) = T.S(n) + B, dominance matrices and ranking
• Networks and decision mathematics: vertex degree and Euler trail/Hamiltonian cycle conditions, minimum spanning tree, shortest path, maximum flow with cut capacities and min-cut justification, project scheduling (EST/LST, critical path, float, crashing)
