    Is Australia racist?

    Is Australia racist?

    All the figures quoted were around 58% being the largest, so with 13% variance still gives a range of approximately 50-70%, so what's the point you are trying to make? The logical argument can be made both ways, genetic factors do not necessarily explain variation in intelligence either - it...

    Is Australia racist?

    Popping in for some remarks and then leaving the conversation. Sylvia is right, IQ is measuring intelligence. The figure can be as high as 80% but 50-70% is probably a more realistic figure for e.g. Devlin et. all (1997) has it has at 49% Chipuer et. all (1990) has 51% Loehlin (1989) has 47%...

    BoS trials Maths and Chemistry 2022

    To answer the first question, not sure. (I didn't penalize it when marking Bos trials) You can use indefinite integrals and then evaluate the initial condition to find the value of the constant. The issue is that t is a variable not a constant. Hence why its not a great idea to do, thankfully...
