Used for LANTITE preparation (Australia). MG = Measurement & Geometry strand. NC = Non Calculator. The start time for Period 1 (randomised) and the end time for Period 2 (randomised) are given, and students are asked to find the middle of those two times. 

Short question in recognising errors in binary strings transmitted over a binary symmetric channel, as well as calculating probabilities of these errors occuring. Randomised 7-bit strings between 64 and 128, randomised probability between 0.05 and 0.1. Randomised error pattern.

Given a randomised rational function select the possible ways of writing the domain of the function.

Students are given an exponential equation and asked to evaluate it at two points.

The constants in the exponential are randomised.

Given a randomised rational function select the possible ways of writing the domain of the function.

Given a budget and the number of views, calculate the cost per view. All numbers are randomised.

Find a percentage of a given population. Percentage and population are both randomised.

percentage rate is 0.5, 1, 1.5 or 2%. Number of impressions is randomised.

Given potential audience, the percentage that view, and the percentage of these that click, calculate the CPA by dividing potential audience by clickers. 

All numbers randomised.

Solve quadratic equations (non-simple case, two real, discrete roots) using the formula. Some, random, non integer roots.

clicks = budget/CPC

All numbers are randomised.

Calculate CTR given number of clicks and number of impressions served.

percentage CTR is 0.5, 1, 1.5 or 2%. Number of impressions is randomised.

Printing errors in the work produced by a particular film occur randomly at an average rate of p per page.

i.What is the probability that a one page document will contain x1 printing error(s)?

ii.If a n page document is printed, calculate the probability of having more than x2 errors. Assume a Poisson distribution.

As it says on the tin!

Random terms including powers of x.
