VCE General MathematicsPractice Examination 18

This paper covers

• Original Exam-2 written paper (Exam 18 of 20) for VCE General Maths U3&4, hospitality flavour: exactly 4 questions x 15 marks = 60, CAS assumed, extended-response with labelled parts.
• Q1 waterfront-bistro data analysis (normal model, 1.5xIQR outlier, least-squares regression with residuals, seasonal indices); Q2 espresso-cafe finance (flat-rate and unit-cost depreciation, savings annuity, reducing-balance loan with final-payment adjustment, perpetuity).
• Q3 hotel matrices (order/product revenue, determinant-inverse solve of simultaneous equations, transition matrix with steady state and S(n+1)=T.S(n)+B); Q4 resort networks (Euler trail, minimum spanning tree, shortest path, max-flow min-cut, project scheduling with float and crashing).
• Every numerical answer independently verified in Python (regression coefficients, amortisation table, matrix powers, Kruskal/Dijkstra/cut enumeration/CPM passes); criteria sum to 15 per question; original content, Australian conventions.

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