# Mathematics A

Course Carole Godfrey
Access code required

The study of financial, geometric, statistical, and operational mathematics.

Mathematics A will assist to:

• Develop knowledge and skills of computation, estimation and measurement;
• Help manage financial affairs in an informed way;
• Develop the capacity to interpret and analyse information presented in a variety of forms;
• Make judgements based on evidence and reasoning.

Here is the course outline:

Weeks 1 - 5

## 2. Basic Calculations

number systems, operations, linear equations, approximation, calculator skills, metric system, rates and ratio

## 3. Elements of Applied Geometry

1 - Perimeters and areas, including compound figures involving rectangles, trapeziums, triangles, circles, quadrants. 2 - Surface area of prisms and cylinders. 3 - Volumes, including compound figures of prisms, pyramids, cylinders, cones and spheres. 4 - Trigonometric ratios and Pythagoras’ theorem. 5 - Latitude, longitude and measurement of time.

## 4. Understanding Data

1 - variables – nominal or ordinal (discrete and continuous). 2 - collecting data –observation, experiments, surveys, random sampling. 3 - interpretation of graphical displays of data including stem-and-leaf plots, bar charts, pie graphs, histograms.

## 5. Managing Money

1. earning money- salary, wage, overtime, commission, piece rate 2. industrial awards (notes) 3. taxation 4. spending money, profit, loss, discount 5. budgeting, owning and running a car

## 6. Linking in Two and Three Dimensions

1 - interpretation of scale drawings and plans. 2 - drawing simple scale drawings and plans. 3 - geometry of bracing for rigidity. 4 - practical tests for squareness and plumb. 5 - estimation of quantities and costs in construction.

## 7. Data Exploration and Analysis

1 - mean, mode, median. 2 - range and inter-quartile range, standard deviation. 3 - 5-number summaries and box and whisker plots. 4 - comparison of data sets.

## 8. Managing Money II

1 - simple and compound interest. 2 - effective and nominal rates. 3 - inflation, appreciation, depreciation (str. Line and diminishing value. 4 - present value of a lump sum payment. 5 - consumer credit- personal loans, housing loans (including cost of loan) loan repayment tables, credit and debit cards. 6 - investments (savings acc., term deposits, real estate and stock market).

## 9. Probability and Statistics

1 - suitability of sample as representative of population. 2 - sample statics as estimates of population parameters. 3 - probability as a measure of chance or likelihood; as a relative frequency of equally likely outcomes; 0 1   P. 4 - tree diagrams. 5 - interpretation in context of row and column percentages for a contingency table.
