Question in How-tos
Shows how to create a simplified JME subexpression, and substitute it into a string variable.
-
Question in How-tos
A demonstration of how to use the "variable list of choices" option for a "choose one from a list" part to shuffle only some of the choices, and always have the same "I don't know" choice at the end of the list.

Question in How-tos
This question uses a "formatted text template" variable to define a long passage of text which is shown to the student after they submit a part. A custom marking algorithm adds the text as a comment after the standard marking algorithm has finished.

Question in Jos's workspace
Solve for $x$ and $y$: \[ \begin{eqnarray} a_1x+b_1y&=&c_1\\ a_2x+b_2y&=&c_2 \end{eqnarray} \]
The included video describes a more direct method of solving when, for example, one of the equations gives a variable directly in terms of the other variable.

Question in Jos's workspace
Template question. The student is asked to perform a two factor ANOVA to test the null hypotheses that the measurement does not depend on each of the factors, and that there is no interaction between the factors.

Question in Algebra Mat140
Crear una tabla de verdad para una expresión lógica de la forma :
$( a \ {op1} \ b) \ {op2} \ (c \ {op} \ d) \ {op4} \ e $
donde cada una de $a, \; b, \; c, \; d, \; e, \; f $ puede ser una de las variables booleanas $ p, \; q, \; \neg q, \; \neg p $ y cada uno de los operados $\{op}$ puede ser uno de los operadores $\lor, \; \land, \; \to$.
Por ejemplo: $((q \lor \neg r) \to (p \land \neg q)) \land \neg r$ -
Question in Lógica y Cuantificadores
Create a truth table for a logical expression of the form $(a \operatorname{op1} b) \operatorname{op2}(c \operatorname{op3} d)$ where $a, \;b,\;c,\;d$ can be the Boolean variables $p,\;q,\;\neg p,\;\neg q$ and each of $\operatorname{op1},\;\operatorname{op2},\;\operatorname{op3}$ one of $\lor,\;\land,\;\to$.
For example: $(p \lor \neg q) \land(q \to \neg p)$.

Question in Tom's workspace
A simple ideal gas law question, using number of molecules, that asks the student to calculate one of the four variables. he question can ask for either L atm, or kPa m3, and either K or C for temp. As such the boltzmann constant is in either J/K or L atm/K.

Question in Ed questions to share
Used for LANTITE preparation (Australia). NC = Non Calculator strand. SP = Statistics & Probability strand.This question provides a list of data to the student. They are asked to find the difference between the mean and the median. This question was based on a Newcastle Uni question which also asked the mode, hence the surplus legacy variables (too tricky to delete).
