networks question 6!!

(1/1)

123321:
itute says that the correct answer is E, me and my friend got D, 15 hours since the dummy has no direction, which one do you think VCAA will make correct???

maxleng:
if VCAA decide the dummy can go either way, then the answer is E

superstar89:
this is my reasoning, in past examinor reports for exam 2, vcaa has always specified that when they want you to draw a dummy it must always show zero weight and a direction. according to this i think they will accept both..i hope i put down D....also u cannot have 2 edges joining the same 2 activities, this would happen if the dummy could go either way....

maxleng:
Yeah thats why i was like ehhh wtf when the dummy had no direction, cos in the 2005 exam where you had to draw in a dummy the specifically said in the examiners report  "for a dummy act a direction and weight = 0 must be shown" so im pretty sure they screwed it up
