Give me answer to the following question
Workout total number of teachers when the probability for female teacher is 3/5 and there are 36 male teachers? It would be my pleasure if u do that

90 teachers

If 3/5 are female, then 2/5 are male

2/5 of the workers are male

2/5 = 36
therefore the total is (36*5)/2 = 90 teachers.

36 male, 54 female

That's 8 marks you've lost there.

I'll have picked up method marks so not completely 8 marks, reckon I'll get 1 or 2 for the Surds/Area one, and about 3 for the Circle Theorems one. Also made like 2 mistakes elsewhere in the paper, but should be comfortably an A* :smile:

For the question about the tiles I did a completely different method that everyone I've spoke to and came to the conclusion that :
No. because she has enough to cover 37.5m^2 but needs to cover 50m^2 so she's 12.5m^2 short
DID ANYONE GET ANYTHING SIMILAR // know if I will get any marks? I was pretty confident on that question lol

I did that but people said she didn't have enough cans instead

Okay so if everyone fails maths GCSE will the grade boundaries be lowered?

Would 1/25 be accepted for question 21 as it is equivalent to 0.04?

Yes, as the fraction is in it's simplest form.

If I remember correctly question 9 was something like find a formula for the total envelops T in terms of x and y. I got something like 5x+20y.

I think i put T = x + 4y, which is the simplified form of 5x + 20y. Is that wrong?

If you wrote T= 5x + 20y in your working and then showing that u simplified it you might get 1 mark but after seeing a full unofficial mark scheme it looks like T= 5x + 20y will get u full marks.
