VCE Further Maths Exam 2 Discussion and Solutions

[winged dragon 151]

I'm totally freaking out! So I think I lost a max of 20 marks combined with both exams and finished with a rank of 7th, what will my study score look like?

Sorry, but can I get your SAC scores and predicted exam scores?

[benson09]

Hey, what study score should I be looking at?
38/40 Exam 1
56/60 Exam 2
SAC Ranking: Top 35% of a strong cohort of 100 students

Also, can someone explain to me why the float time is 6 days and not 7 in the networks module? Thanks 

[hk9191]

What about rank 1, 40/40 and 59/60? 50 still in question, or will it be too competitive at the top?

of course!
data and stats: 87%
geometry: 80%
linear: 83%
exam 1: 29/40
exam 2: 51/60

What kind of score?

[abbie_roseee]

If we did 6b wrong, will we get consequential marks for part c??

Answers so far:
Core Q1ai 72
              aii 25%
              bi 84%
                ii 209
               c  105
            2a   place of capture
               b  20mm
               c  min 16mm  Q3 36mm
               d  52 is greater than upper fence 50 so it is an outlier
               e  The median wingspan of moths in grassland is 30mm when compared with median wingspan of moths in the
                    forest of 21mm. Wingspan is therefore associated with the location where they are caught.
             3a  egg density = -46.8 + 18.9 x number of male moths
               bi choose two points to input into equation given ie (10,504) and (60,2064) and draw line.
                ii for every additional female moth caught the egg density increases on average by 18.9.
               iii -412.5
               iv 74.3% of variation in egg density can be explained by the variation in number of female moths caught.
            4a   0.009
              b    log(area) = -14.4 + 0.009 x year
              ci  708 hectares
               ii  Extrapolated result
             5a 3375, 71625, 3375, 68250
               bi $3375
                ii 4.5%
               c  5.7%
              6a $203
                b Ao = 428, An+1= 1.015 x An
                c  $454.26
               7a  $1560
                 b  $805.65

Just to add to the onslaught of study score questions!
If I got 93,94,96% on sacs with a ranking of about 5
And got
39/40
58/60
What am I looking at?

[goonera]

what am I looking at with a
37/40 for exam 1
52/60 for exam 2
and maybe like 7th or higher rank

[Peter123123123]

Hey, can anyone tell me what study score I could be looking at? (A range would be awesome
SACS: 85/100
Exam 1: 39/40
Exam 2: 59/60

My answers. Please let me know if you believe there are errors

Are you able to get working out marks for the 30%/25% matrices question if you wrote 0.3*200=60? Or at least half a mark (to a consequencal mark)?

[Paolo Grande]

This may be possible as it shows that you have part of the working out requirement.

Isn't the last graphs and relations question = 9 and 3

[kirstfletch99]

My answers. Please let me know if you believe there are errors

So there were a few things I got different (could have just been typos you made idk)

DATA Q1bii) I got 975 because 97.5% of 1000 is 975 not 9750.
DATA Q3a) Your value of 46.8 needs to be negative (probably just a typo?)
GEOMETRY 2a) I got 8pm Wednesday because you need to subtract 2 hours to account for the fact that they said the two places had a time difference of 2 hours, and the destination was further East so you would have "gone back in time" *I don't fully remember the question though so I would ahve to read it again to be sure.
GRAPHS Q3d) I got 9 and 3 because you can't just simply round, you have to look at the graph and find the integer (whole number) solution points near the corner point that gives you the minimum. This point was (9.6,2.4) and the two closes integer points that are INSIDE the solution region are (9,3) and (10,3) however (9,3) will obviously give you a smaller value than (10,3) so that's why I wrote that instead
