Lads was the orthocentre in question 1b (7,6)? would cheer me up.

exam — 13/06/16

Sean_2988 — 13/06/16

ddp.cronin — 13/06/16
What did you get for the rate of change of the height if the wave and did you use differentiation?
Jack_6159 — 13/06/16
I couldn't do it

What did people get for the centre of the circle in q2? I got (200/17,133/17) definitely wrong I think
ddp.cronin — 13/06/16

Katie_6240 — 13/06/16

Sean_2988 — 14/06/16

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 — 14/06/16
yeah. Hope its not a maths teacher
tomz — 14/06/16
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...
Sarah654 — 14/06/16
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
shannon8 — 15/06/16
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 — 15/06/16
Did anyone get 15 meters squared for that glass question
Sarah654 — 15/06/16
I think I did
Aaron125 — 15/06/16
the top of the table for the tide times is wrong too isn't it?
ddp.cronin — 15/06/16
The table seems right to me.
Aaron125 — 15/06/16
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?
Sarah654 — 15/06/16
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
