Sample ACT BSSS Year 12 Mathematical Applications questions

These sample questions are visible on the page before login. They show ACT BSSS Year 12 Mathematical Applications data, finance, matrices, networks, trigonometry, and decision-mathematics explanations before opening the demo.

ACT BSSS Year 12 Mathematical Applications Time series hard forecast graph

1. A trend model predicts 146 bookings for a quarter. The seasonal index for that quarter is 1.08. What is the seasonal forecast, to the nearest whole booking?

Seasonal forecast from trend and index T S 158
Choices
  • 158
  • 146
  • 135
  • 154
Explanation:

Apply the seasonal index to the trend value: 146 x 1.08 = 157.68, which rounds to 158 bookings.

ACT BSSS Year 12 Mathematical Applications Loans and investments hard finance graph

2. A loan balance follows Bₙ₊₁ = 1.005Bₙ - 520 with B₀ = 18000. What is B₂, to the nearest cent?

Loan recurrence after two repayments B₂ n $
Choices
  • $17,137.85
  • $17,570.00
  • $18,090.00
  • $16,960.00
Explanation:

B₁ = 1.005 x 18000 - 520 = 17570. Then B₂ = 1.005 x 17570 - 520 = 17137.85.

ACT BSSS Year 12 Mathematical Applications Critical path analysis hard critical path diagram

3. A project has three possible branches before final task F: A-C-F takes 4 + 6 + 3 days, B-D-F takes 5 + 7 + 3 days, and B-E-F takes 5 + 4 + 3 days. What is the minimum completion time?

Critical path through a project network S F 15
Choices
  • 15 days
  • 13 days
  • 12 days
  • 40 days
Explanation:

The branch totals are 13, 15, and 12 days. The project duration is controlled by the longest required branch, so the minimum completion time is 15 days.

ACT BSSS Year 12 Mathematical Applications Matrices hard transition diagram

4. A row state vector [city, regional] = [480, 320] is multiplied by transition matrix [0.76, 0.24; 0.35, 0.65]. How many customers are expected to be in the city state next period, to the nearest whole customer?

Two-state customer transition C R T
Choices
  • 477
  • 480
  • 523
  • 800
Explanation:

Use the city column: 480 x 0.76 + 320 x 0.35 = 364.8 + 112 = 476.8, which rounds to 477.

ACT BSSS Year 12 Mathematical Applications Expected value hard weighted score chart

5. A promotion gives a $120 prize with probability 0.18, a $40 prize with probability 0.35, and no prize otherwise. Entry costs $25. What is the expected net gain per entry?

Expected value decision chart $ P E
Choices
  • $10.60
  • $35.60
  • $25.00
  • -$10.60
Explanation:

Expected winnings are 120 x 0.18 + 40 x 0.35 = 21.60 + 14.00 = $35.60. Subtract the $25 entry cost to get an expected net gain of $10.60.

ACT BSSS Year 12 Mathematical Applications Bivariate data hard regression graph

6. A regression model predicts demand with y = 52 + 1.8x. For x = 14, actual demand is 81. What is the residual, using actual - predicted?

Residual from a demand model P L r
Choices
  • 3.8
  • -3.8
  • 77.2
  • 81
Explanation:

The predicted value is 52 + 1.8 x 14 = 77.2. The residual is 81 - 77.2 = 3.8.

For parents comparing ACT BSSS Year 12 Mathematical Applications support

ACT BSSS Year 12 Mathematical Applications practice should make data, finance, matrices, networks, trigonometry, and decision-mathematics feel structured rather than guessable. These examples preview that style before the no-login Mathematical Applications demo.
