What did people get for Networks Q8? I answered D (3).

Yep I did D = 3 as well....
I got G, I and N as the ones with a float time of 10...don't know if that's right though

I got E (4) but looking back on it now its definitely D 😫

1 E
2 C
3 C
4 A
5 B
6 A
7 B
8 D

i lost 10 marks
can i get 40, if i get 80%+

What did everyone get for question 7 of matrices?

I went with 1 (B), but found the wording of the question to be a little ambiguous. I found it unclear whether or not the "other" was referring to any person "other" from "Y" (including W) or a person "other" than W, I assumed it to mean any person "other" than Y so went with B since Y can communicate directly to W. Also if it did mean one other from W, did it mean as in from Y directly to one other person and then directly to W, in which case there would be 0 ways. Or did it mean from Y directly to one "other" than W and then whatever as long as it gets to W, in which case there would be infinite ways.

Also I just realised I mixed up Networks Question 4  , would have realised if I had time to read over that section, exams suck.

I'm so sorry if this is a bother, but I redid it again and I'm pretty sure I got 4 (E) again, would you be able to point me through how to do it or which ones have a float time of 10? Thanks!

Here are the answers to core, matrices and graphs and relations. I've cross checked them with a bunch of friends, so we think it's 100%, pls let know if any wrong ones in it.

I was close to answering C (2). Lucky I checked edge I.

So the reason I got 4 was because i accidentally wrote the wrong LST for activity F/G. I did 19-3=16 (using the G path) rather than choosing the lowest option (18-8=10 ie the F path). The activities with a float time of 10 were G, I and N however because i wrote the LST for F and G as 16 i also got activity D. You might have done something similar and made an error in your forward or backward scanning.

Was a little unsure of Q7 in matrices, but everything else seems right,
Anyone else get similar?

Hii, can I ask why Core Question 15 is 103 (D)? I was unsure of my answer so I'd like to ask how you found it. Thanks so much!!

Ah yes, I see it now, from A-D-F-K-O? Thanks!

I think the process is like this. There are 12 months so the median must be between the 6th and 7th values. The 6th and seventh highest rainfall is like 96ish and 110. Average the two and you get 103.

Omg nooo I understand my mistake now. I looked at the values as they were, not ordered. So my 6th and 7th values were June and July instead if July and September. Thank you!

for matrices q7 did anyone feel that the wording was ambiguous or was it just me

when it says "by sending it directly to one other person" i thought of from Y directly to W when i was checking through my answers even though i initially had the two-step answer because of the wording ://

also can someone check geometry & measurement with me please
