terry lee's 3u (1 Viewer)

[jah_lu]

here's his draft
few errors though
graph one i tink is x<4
and probability is 1-0.68=0.32
and last question he didnt factor in m=1 so rnage is 20

Yep - they are the old mistakes in terry lee's answers that i see. Hopefully he will correct them soon.

So that's Q3(b)(ii) should be x < 4 not x < 2.
Q4(a)(iii) should be 0.32 not 0.68
Q7(b)(iv) should be 19.51 <= x <= 20 so range is 0.49 or 0.5 (if rounded to 1dp)

Re: 回复: Re: terry lee's 3u

63/84 is that a good mark?

 

[jah_lu]

its decent
probably not enough for e4
but should get you 85+

 

[tanguyen]

argh... stupid stupid marks, 5 due to carelessness. Hoping for 78 as a minimum. *beats head on wall of nails*
