  • j's copy of Several variables corresponding to a scenario - Swansea

    by j hopkins and 2 others

    Choose from one of several pre-defined scenarios, and set variables to the corresponding values, defined in lists.

    This question has three variables: city, population, and percent_like_chocolate. These differ for each city. We've defined a list for each variable, with the corresponding values. A variable called scenario picks a random position in the list, so the value of city, for example, is cities[scenario].

  • Mark the product of two matrices in a mathematical expression part

    A mathematical expression part whose answer is the product of two matrices, $X \times Y$.

    By setting the "variable value generator" option for $X$ and $Y$ to produce random matrices, we can ensure that the order of the factors in the student's answer matters: $X \times Y \neq Y \times X$.
