QCE General MathematicsPractice Examination 6

This paper covers

• Bivariate data: least-squares regression, Pearson r and r-squared interpretation in context
• Time series: 4-quarter centred moving averages, seasonal indices, deseasonalising actual data
• Arithmetic and geometric sequences: equipment depreciation and ore-stockpile decay modelling
• Earth geometry and time zones: great-circle distance along a meridian and AEST/AWST shift scheduling across the Mount Isa-Townsville-Perth supply chain
• Financial mathematics: compound interest with varied compounding periods, reducing-balance loan amortisation tables, annuities and sinking funds
• Networks and graphs: adjacency matrices, Euler's formula, Dijkstra's shortest path
• Decision mathematics: maximum-flow minimum-cut, minimum spanning trees, critical path analysis (forward/backward passes, float), and Hungarian-algorithm assignment
• Complex unfamiliar multi-step problems: two-phase investments, loan refinancing with rate change, and reasonableness/limitation evaluation in a mining-logistics context
