QCE General MathematicsPractice Examination 16

This paper covers

• Time series analysis: trend, seasonal indices, deseasonalisation and deseasonalised-trend forecasting (Queensland Health flu vaccination context)
• Bivariate data: Pearson's r, coefficient of determination R², least-squares regression, residuals and two-way tables
• Arithmetic and geometric sequences and recurrence relations (dose delivery and cold-chain decay)
• Earth geometry and time zones: distance along a parallel of latitude, longitude-to-time conversion
• Financial mathematics: compound interest recurrence, reducing-balance loans, annuities (future value) and perpetuities
• Graphs and networks: adjacency matrices, Euler's formula, Dijkstra shortest path, walks
• Decision mathematics: minimum spanning trees (Kruskal/Prim), maximum-flow minimum-cut, and critical path analysis with forward/backward pass and float

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