      What did you get for the rate of change of the height if the wave and did you use differentiation?

      Some of those answers are wrong. For example in q9 he has the cut off point of 10% as equal to around 40000€ , but how can the lowest 10% of income earners earn more than the average income of 39000

      Sean_2988

      yeah. Hope its not a maths teacher

      For the very last question there was no mention of 95% confidence interval so I thought we couldn't use that formula? Or do we just assume it is...

      Yah on question 9 on paper 1 there is a mistake in the thing you had to fill in about what affect it had on the x or y axis e.g plus or minus in leith

      The glass pyramid one is wrong as well because the it had a rectangular base so not all 4 triangles were the same area , 2 were the samw as eachother and the other 2 were the same

      Dank

      Did anyone get 15 meters squared for that glass question

      the top of the table for the tide times is wrong too isn't it?

    29. avatar image

      ddp.cronin

      The table seems right to me.

    30. avatar image

      Aaron125

      But 't' is 'the number of hours since the last recorded high tide' and there was a high tide at 12 noon. Should it not start at 3 again from 3pm?

      The table is right on paper to like the range of the graph for 3.1 to 0.1 and they are in the table
