    For the question with two triangles, I used sine rule and not pythagoras but still got 30.1 (by doing 180-90-59.926). It said that you must show working so would I still get marks? It's technically correct

    I got told you always round up to nearest whole number of people in stratified sampling by my teacher, as it works out to be the right number of people in the sample as other classes have 2.2 for example, evening it out.

    If you round before the final answer u get 80.4 if you are accurate and don't round and keep the sins in the equation you get 80.1
    I didn't round until the end but got 80.4

    7(c) was not 2.61m. It wanted a 145% increase and 2.61m is only a 45% increase. You needed to find 100% of 1.8 (double it) and find 45% of 1.8. Add these two values together (3.6m and 0.81m) to get 4.41m.
