Yo, I was wondering, for the last question I put 73.1 degrees which I know is wrong, however, the only reason why i got it wrong is because when I subbed in the values into the formula for the area of a triangle, for some strange reason I did cos inverse instead of sin inverse giving me 50 degrees instead of 40. The rest of my method was correct do you think I will only lose 1 mark?

I would think you would lose 1 mark. It's a just stupid mistake like me who forgot to put a god damn ass key in the first question! The amount of past papers I've done and I forgot to put a key! :angry:

1b Definitely not 47.5%
It was 9/20 = 45%

ugh i rounded the gallons to 4 and the litres to 19 for the Collins question and got £43.51. You can't possibly get 18.1 litres of petrol exactly can you?

When you buy petrol from a petrol station, there's a meter that tells you exactly how much petrol you're filling your car with, and I believe it's to two decimal places.

Anyone know if the paper is going to be posted with full workings like last time with the non calculator?

I'll see what I can do

Predictions for an A? Got about 123/200. :smile:

A* = Roughly 169
A = Roughly 132
B = Roughly 98
C = Roughly 77

Anyone know how many marks I will get for putting 9/20 for the 2nd question instead of 0.45?

They better have a little bit of range with the last question as I put 80.3

If I have the correct numbers,

This is one way of doing last Q

Area = ( absinC)/2

Sin^-1 C = 18x2/(7x8)

= 40.00520088 degrees (DO NOT ROUND)

a^2 = b^2 + c^2 - 2 x b x c

= 27.20955764 cm (DO NOT ROUND)

Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

= 80.37550115

= 80.4 degrees

it is fine ------->>> from 2015 mark scheme before the answers start
Probability
Probability answers must be given a fractions, percentages or decimals. If a candidate gives a decimal equivalent to a probability,
this should be written to at least 2 decimal places (unless tenths).
Incorrect notation should lose the accuracy marks, but be awarded any implied method marks.
If a probability answer is given on the answer line using both incorrect and correct notation, award the marks.
If a probability fraction is given then cancelled incorrectly, ignore the incorrectly cancelled answer.
yu could put 45% and get mark
