Here are my solutions.

Re: A rhombus with vertices A (1,6) B (6,6) C (-2, 2) and D (x, y) ?? It can't be ABCD. AB=AC=5 but BC=4sqrt5. So BC must be a diagonal, making D (3,2) , which is 5 units to the right of C.

Thank you! Does the James Ruse Ext 1 paper have answers?

Because General does Permutations & Combinations (at a simple level) in their Applications of Probability topic.

There are 9C6 ways of choosing 6 campers from 9 ( = 84) There are 5C3 ways of selecting 3 boys and 4C3 ways of choosing 3 girls ( ie 10 x 4 ) So the probability of choosing 3 boys and 3 girls is 40/84 = 10/21

Did you try multiplying 0.5 by 0.2?

These are the equations of parabolas with the same vertex, which they should not. The latus rectum passes through the focus of each parabola , which will be the point (4,3). Since the focal length is 1 unit, the vertices are: (4,2) for the parabola that is concave up --->...

Thank you for your papers + solutions. Do you have the General Maths solutions to Barker ?

Here are some 2011 Maths papers from Warners Bay High:
