Question in MfEP Progress Quizzes
Students are asked to solve two simulatineous linear equations in an application of mixing two liquids to arrive at a given final volume and concentration. Students are expected to write up working for their solution and upload it seperately. Final volume, final concentration and concentrations of each solution are randomised.

Question in MfEP Progress Quizzes
Question asks student to find zeros of a quadratic equation. In this version students are expected to write up their working and submit it seperately to the Numbas question. Students are expcted to recognise that only the positive solution has physical significance.

Question in MfEP Progress Quizzes
Question asks students to find the time taken for an object thrown vertically upward from a platform to reach the ground. Set up randomly chooses environment to be on Earth, Mars or the Moon and uses appropriate acceleration due to gravity. The initial velocity of the body and height of the platform above the ground are randomly selected. In this version students are expected to write up their working and submit it seperately to the Numbas question. Students are expcted to recognise that only the positive solution has physical significance.

Question in Toby's workspace
Plot the Fourier series coefficients for a piece-wise linear function. Write a Python script to reproduce the same figure.

Question in How-tos
In the first part, the student must write any linear equation in three unknowns. Each distinct variable can occur more than once, and on either side of the equals sign. It doesn't check that the equation has a unique solution.
In the second part, they must write three equations in two unknowns. It doesn't check that they're independent or that the system has a solution. The marking algorithm on each of the gaps just checks that they're valid linear equations, and the marking algorithm for the whole gap-fill checks the number of unknowns.

Question in How-tos
A random proper fraction $a/b$ with denominator in the range 2 to 30 is picked, and the student must write $\frac{a}{b} \pi$.
The point of this question is to demonstrate that the correct answer is shown as a multiple of $\pi$ rather than a decimal.

Question in HELM books
Two functions given in words. Write down the function definition. The numbers in the function definitions are randomised.

Question in Demos
In the first part, the student must write an R function to compute the first $n$ terms of the series $\frac{1}{k!}$.
In the second part, they must use that function to calculate an approximation to $e$ using a given number of terms of the series.

Question in Demos
Given an unknown list, the student must write Python code to create a copy of it.
There's an alternative to catch the case where the student's variable is just a reference to the original list.
-
Question in Demos
Given an unknown list, the student has to write code to return the last item in the list.
-
Question in Demos
Given a randomly-generated list, the student must write code to return its first value.
There's an alternative to check if they get the second item, which they might do if they don't realise Python lists are zero-indexed.
-
Question in Demos
The student must write code to compute the standard deviation of an unknown list of measurements.
The suggested answer uses numpy.std.
-
Question in Demos
This is the simplest demonstration of the "code" part type I could think of: write Python to assign
x = 1
.An alternative answer gives a hint if the student's code doesn't define x at all.

Question in Demos
In four parts, the student builds up the definition of a class representing a rectangle. First they write the constructor, then add methods to compute area and perimeter.
In the final part, they must use the methods to write a function which determines if a rectangle's area is larger than its perimeter.

Question in Odds and Ends
Written for the Western Sydney University MESH numeracy preparation workshop for the LANTITE test (Australia). Students are given a height in centimetres and another height in metres, and are asked to write the ratio of the two heights in simplest form. There are 16 versions of this question.

Question in Bin
A measurement is performed multiple times for the same object, the student will
- calculate the mean result
- calculate the standard error on the mean
- write the mean±error to the correct precision as defined by the error written to 1 significant figure
Advice is provided including on performing the calculations in Python or spreedsheets together with further reading.
