Can somene tell me plz; i made a small calculation error on the last question and got 81 instead of 80.4, i was wondering how many of the 6 marks ill get on it?

Probably 4 or 5 because my teacher always says the final answer is worth a mark but dont worry im sure you did fine

I did register to this forum with my e-mail address provided following instructions via e-mail sent to me by you. Strange.

I managed to get the workings to 40.005 degrees. But I stupidly put this as the final answer!! Do you think this will get me 1/2 or more marks?!

1 mark probably

How many marks was the first page worth? ( the stem and leaf diagram)

3 marks for the stem and leaf.
2 marks for the probability.

So 5 marks in total.

Realised I used the upper bound for U instead of the lower bound...

Can any one explain to me the upper bound question :smile:

it's I = 5(v-u)

You need to work out the upper bound of I.

So to work out the upper bound (so the higher value) of I you need to get the highest value in your answer.

So 5 x (UPPER - LOWER) will give you the upper bound (higher overall).

e.g.
(5 - 1) = 4

(5 - 2) = 3

so for the upper bound of I (higher value) you need the upper of v and lower of u, 5 x (upper - lower)

That's exactly what I got taught and why I put 3.7 because you compare how close they are to it

The question:
The question: The equation - x^3 - 5x = 34has a solution between 3 and 4Use trial and improvement method to find this solutionGive your answer correct to 1 decimal placeYou must show all your working

correct to 1d.p. doesnt mean to round from a number. you need to find the closest number that is to 1 d.p. we're on the same page here :smile:

Let me explain it to you:

the value of X was NOT 3.75 (it was too small)

so it must have been somewhere after 3.75

WHICH ROUNDS TO 3.8

It's a common mistake. I done the same mistake as you when I done a practice paper a few days ago lol.
