NOTES: Minimum point of a quadratic: probably easier to solve derivative = 0 rather than completing the square? Also, don't forget to find the y coordinate!
NOTES: An easy-ish exponential modelling problem because there are no unknowns to find. Word question: "Give reason why the model may not be appropriate"
NOTES: First 6 marks should be easy. Last 4 marks are easy if you use a sketch and label the right angle, the coordinates of the centre, and the coordinates of Q.
NOTES: Has a factor of 12' means that it can be written as 12(.......) so aim for that in (a). For (b) try a couple of odd numbers - is it still a multiple of 12?
NOTES: Common word questions, worth learning: "Identify an outlier", "explain why the mean is not a good measure of average", "suggest a reason for the outlier"
NOTES: A good practice question, covering binomial distribution, sampling and a hypothesis test! Word questions: "Name the sampling method", and "describe the weakness of this sampling method"
