GCE O Level Oct/Nov 2010 E-Maths 4016 Paper 1 Suggested Answers & Solutions???

(43)
Tuition given in the topic of Miss Loi the Tutor from the tuition centre desk of Miss Loi at 11:40 pm (Singapore time)

The first skirmish in this Week of Mathematical Armageddon occurred this afternoon, and since then the Battle Control Centre that is The Temple has gone into overdrive with reports from the battlefields across Singapore.

Thank you Ms Loi. Today’s paper was relatively easy.

Paper one went relatively well =)

2day was easy!

I found the paper very manageable. I had time to re-check.

Ms Loi!! The paper hard siak!!!!!!! (Miss Loi: Aiyooo … *shakes head*)

Interspersed among these frantic messages were more frantic messages and calls from unknown students who allegedly “couldn’t stand the uncertainty anymore” and kept pestering asking Miss Loi when would the EMaths Paper 1 solutions be posted up.

Unfortunately, since the answers were written on and handed in together with the question paper, the ‘O’ Level EMaths Paper 1 question paper tends to be a bit of a holy grail of exam papers these days.

And since The Temple does not have the evil policy of asking its students to steal, smuggle or even copy out the questions during the exam itself (obviously, ANY spare time is better spent on checking the answers more than anything else), Miss Loi unfortunately couldn’t produce any solution without the questions.

But as fate would have it, just as Miss Loi was letting out a sigh of resignation, a student strode into The Temple, held a couple of pieces of paper high in the air and exclaimed “MY SOLUTIONS!!!!!!!!!”

And so in order the pacify the anxious callers, this is what Miss Loi can offer here for now as far as 2010 EMaths Paper 1 goes (in the absence of the question paper):

O-Level October/November 2010 EMaths 4016 Paper I Solutions (Tentative)

O-Level October/November 2010 EMaths 4016 Paper I Solutions (Tentative)

Please understand that these solutions have NOT BEEN CHECKED BY ANYONE AT ALL, apart from the student who claimed to have 45 mins of spare time to do this during the exam (aiyohh …), and there are bound to be some mistakes (in fact the student-in-question has already admitted some have been spotted). But given the situation this would have to do for all of you who are anxious to see if anyone gets the same answers as you. Alright the verified ones are up above (albeit late – sorry Miss Loi’s students don’t possess superhuman mega memory abilities to recall the entire set of EMaths Paper 1 questions :P ) So do leave a comment should you spot something that isn’t right, and do pardon the messy chunk of words towards the end.

But MOST IMPORTANTLY, it’s time to turn your attention to tomorrow’s EMaths Paper 2, and here are some of the remaining topics that you may want to focus on:

One down, one or three (depending on whether you take AMaths) more maths papers to go! It’s coming thick and fast now!

ALL THE BEST & GANBATTE!
頑張って!!!

    Thks for your tentative solutions for 2010 EM P1. I am inquiring why 1/ 2*x^-5 = x^5/2 for Q4(b) since this question is NOT 1 / (2*x^-5) , right? Shouldn't it be 1/2 * (x^-5) ?

    As for the 2n-1 thing, i think 2n-3, 2n-5 is possible. Of course 2n+1 and 2n+3 are definitely correct. Question nvr specify if it was decreasing or increasing, and patterns can be decreasing as well.

    For question 14b), the answer is 3.33 nanoseconds, not 3 X 10^17 nanoseconds. Calculation error somewhere...
    For question 8, is it okay to draw just one line with a full dot above -3 and a circle above 7? I've done that previously but I'm not sure if Cambridge accepts it...
    @Peter: Confirmed and checked with my school's maths teachers. It's 2n+1 and 2n+3. Good job!

    I agree with fred. it could be either way, up or down. this is a ambiguous case.

    i'm sorry, but apparently you misread the question for the probability question. It says all the dice are thrown at the same time. So for the last part, you can't x 3 for the answer

      @Sanchez: Alright Q11(c) asks

      If three dice are thrown at the same time, what is the probability that the total of the three numbers shown is 17?

      First of all can we agree that for this to happen, one of the the following three cases has to occur?

      6,6,5
      6,5,6
      5,6,6

      Taking the first case: what is the probability that when three dice (let's label them A, B and C) are thrown together, we get Dice A showing 6 AND Dice B showing 6 AND Dice C showing 5?

      Since whatever each dice ends up with is independent of the other two dice, we multiply i.e.

      P(6,6,5) = 1/6 × 1/6 × 1/6

      So it follows that

      P(6,5,6) = 1/6 × 1/6 × 1/6
      P(5,6,6) = 1/6 × 1/6 × 1/6

      However we only have one chance to throw the three dice together. So we'll either get 6,6,5 OR 6,5,6 OR 5,6,6 i.e. P(6,6,5), P(6,5,6) & P(5,6,6) are mutually exclusive events since when one occurs the others cannot possibly occur
      ⇒ so we add them up ...

      ∴ P(Sum of 3 dice = 17) = P(6,6,5) + P(6,5,6) + P(5,6,6)
      = (1/6 × 1/6 × 1/6) + (1/6 × 1/6 × 1/6) + (1/6 × 1/6 × 1/6)
      = (1/6 × 1/6 × 1/6) × 3
      = 1/36
