For question 3, I PUT x=37/4 INSTEAD OF 9.25. Will I still get all the marks???
I am not sure. I thought that because it is a calculator exam you had to put it as 9.25 you will deff get most marks. If not all
5. (Original post by Mathsteacherwess)
Yes you get the marks for that
You'd probably lose one mark but I think you'd get full.

6. Could someone kindly provide the working out for question 17, the trigonometry and Pythagoras theorem one?
7. Do you think I could get 3/6 marks if I only worked it out until the 40.0052 degrees part?
8. Well I think the only question I got wrong is question 21....on which I put 14.4 as the greatest. I'm not sure.

About the last one I got 80.1 and did get 80.4 while checking in the other way. I think it's only a matter of how precisely you keep your previous calculation. I kept previous figures to 2 decimal places and got 80.1 'n confident that my process can't be wrong.

okay so the question was how much did it cost every week..and they gave u this info
parking costs 3.50
he travels to work and back from there to home
to work is 18 miles
45.2 miles is 1 gallon
1 gallon is 4.546
1litre costs 136.9 pence

Parking is 3.50 * 5 = 17.50 - put that to the side
travel to work is 18 * 2 (to work and home) * 5 which is 180 miles
do 180/45.2 to find how many gallons that is and its 3...something, keep the number and dont round it off
do the answer for the top part * 4.546 to find out how much litres
the answer is around 18... something, again dont round it off. use the answer for the next part (18...) and multiply it by 136.9 pence
divide the answer from that by 100 to get it in pounds, the answer for that is 24.7837460177. You obviously can not round that down to 24.78 because the extra part doe snot just disappear so you round it up to 24.79. Then you do 24.79 + 17.50 and u get 42.29..
right?
Do you think I could get 3/6 marks if I only worked it out until the 40.0052 degrees part?
I was told this is 2 marks

For the stratified sampling i rounded 10.8 to 10 instead of 11, will i lose a mark?
I done the same
13. (Original post by 34908seikj)
Wasn't the last question like 1/2 * 7 * 8 Sin(X) = 18

56Sin(x) = 36

Sin^-1(36/56) = X

x = 40

???

I think I did it wrong then.
i did the exact same. do we atleast get a single mark?

Same, the paper was pretty easy but I did rush at the end
