tomz
Same I got a loss too, and 3€ for the next part

Jack_6159
same tomz

ddp.cronin
Yeah I got 3€ and something like 21 c

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

Jack_6159
I couldn't do it

Fjfj
What did people get for the centre of the circle in q2? I got (200/17,133/17) definitely wrong I think

ddp.cronin
One was 7 , that's all I remember

Katie_6240
i got (7,6) or (6,7) cant remember which for the centre of the circle

ddp.cronin
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

tomz
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
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
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

Sarah654
I think I did

Aaron125
the top of the table for the tide times is wrong too isn't it?

ddp.cronin
The table seems right to me.

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?

Sarah654
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
