Year 11 Mathematical Applications practice questions
This public preview page identifies the planned Year 11 Mathematical Applications demo route and links it to curriculum coverage while the reviewed sample question set is being completed.
Sample-question focus
The planned public sample is for Year 11 Mathematical Applications practice and will open after the demo questions are reviewed.
Skills covered
Practice algebra, functions, statistics, probability, discrete applications, finance, and modelling.
Exercise and test mode
The route is public now; the exercise and test preview will become available after the curated question set is ready.
Curriculum link
Compare this demo with the ACT Year 11-12 Mathematics curriculum page to scan related topics, subtopics, and pathway coverage.
Sample ACT BSSS Year 11 Mathematical Applications questions
These sample questions are visible on the page before login. They show ACT BSSS Year 11 Mathematical Applications data, finance, matrices, networks, trigonometry, and decision-mathematics explanations before opening the demo.

1. A regression model predicts fuel use with y = 14 + 2.3x, where x is load in tonnes. For x = 9, actual fuel use is 38.8 L. What is the residual, using actual - predicted?
Choices
4.1
-4.1
34.7
38.8
Explanation:
The predicted value is 14 + 2.3 x 9 = 34.7. The residual is actual - predicted, so 38.8 - 34.7 = 4.1.

2. A row state vector [active, paused] = [650, 350] is multiplied by transition matrix [0.82, 0.18; 0.30, 0.70]. How many members are expected to be active next month?
Choices
638
712
650
1000
Explanation:
Use the active column: 650 x 0.82 + 350 x 0.30 = 533 + 105 = 638.

3. In the network, the shortest route from A to F uses A-B-D-F. If the edge weights on that route are 6, 4, and 7, what is the shortest distance?
Choices
17
19
21
24
Explanation:
Add the weights on the stated shortest route: 6 + 4 + 7 = 17. The competing routes are longer, so the shortest distance is 17.

4. A surveyor stands 48 m from a tower. The angle of elevation to the top is 21°. What is the tower height, to the nearest 0.1 m?
Choices
18.4 m
17.2 m
44.7 m
124.7 m
Explanation:
Use tan(21°) = height / 48. The height is 48 tan(21°) = 18.425..., which rounds to 18.4 m.

5. An investment of $6400 earns 4.8% p.a. compounded quarterly for 18 months. What is the balance, to the nearest cent?
Choices
$6,874.85
$6,860.80
$6,707.20
$7,040.00
Explanation:
There are 6 quarters, each at 1.2%. The balance is 6400(1.012)6 = 6874.847..., so the balance is $6874.85.

6. Venue A costs $180 plus $12 per person. Venue B costs $420 plus $8 per person. For how many people are the costs equal?
Choices
60
40
80
150
Explanation:
Set the costs equal: 180 + 12p = 420 + 8p. Then 4p = 240, so p = 60 people.
For parents comparing ACT BSSS Year 11 Mathematical Applications support
ACT BSSS Year 11 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.

In progress
Year 11 ACT Maths - Mathematical Applications is available to purchase, and the public demo preview is still being prepared.
Students can use the purchased subject once subscribed; this anonymous preview will be opened after the curated public question set is ready.
Does this page include Year 11 Mathematical Applications practice questions?
Not yet. The Year 11 Mathematical Applications demo route is public, but the interactive sample questions will open after the reviewed public set is ready.
Can students try the demo without signing up?
No sign-up is required to view the preview status. The no-login interactive demo will be available after the sample set is completed.
How does this demo relate to curriculum coverage?
This demo is linked with the ACT Year 11-12 Mathematics curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
