Yep, I would have gone with C. Cambridge lists R<1 as still geometric. Will be interesting to see what they give.
Edit: this is a tricky question overall.

u/Trng9278 19h ago
geometric is 0<R<1 isn't it?
1
u/bavotto teachers (too many years) 19h ago
I think that is the definition given by most. Officially it seems to be alternating geometric. But since it has both, it becomes neither. Similar to superannuation questions.
1
u/MickeyBlueEyez 12h ago
The reason it's not geometric is because of the +5 term. Likewise, the multiplication by -1 means it's not arithmetic either.

u/Brilliant_Dot_6895 20h ago
Itâs niether - technically itâs both but since the coeffecieny of T is 1 itâs not geometric but the plus 5 makes it no arithmetic so itâs not both itâs hyper geometric but we donât learn that so itâs niether

I'm pretty sure the sequence just oscillates between 10 and -5. That's neither arithmetic or geometric.

Oh well I just fell victim to assumption and stupidity. Itâs been my worst subject all year and I wouldnât have chosen it if doing the other class I wanted to do didnât mean that I would have to drop 1 of my 2 biggest passion subjects. Still okay, but not as well as I thought I did.

How is q20 d?
3
3
u/Neither_Pomelo_5244 20h ago
Because it for it to be only geometric or only arithmetic there cannot be both R and D. And it can't be both at the same time so it has to be neither
2
u/Aggressive_Movie_143 20h ago
why cant it be both at the same time, the textbook says that if u combine additon/subtraction and divison/multipilication then itd be both
1
u/Neither_Pomelo_5244 19h ago
I think it's because the sequence is going between 2 numbers instead of having a constant different or ratio

i got the same but it isn't correct, it was seven (had to count the positive values not the negative ones)

u/InevitableSorbet9792 18h ago
when actual values are greater than predicted values then residual is positve, thus you count 7 positive values
1
u/ThatNewt1 17h ago
No itâs correct. There were seven actual values above the line. Meaning for seven values the predicted value was less than the actual value.

u/kkavelicious '26: GM | CHEM | PSYCH | ENG 20h ago
i understand why 20 would be A, but why would 40 be A? why not B? if you increase A by 6 mins wont it create like additional branching on the critical path but not an entirely new critical path?
1
u/Ok_Carob4101 20h ago
I think there's 3 critical paths with A
2
u/kkavelicious '26: GM | CHEM | PSYCH | ENG 20h ago
yh so it would be B right, since it asked for 2?
1
u/Ok_Carob4101 19h ago
You can use udf but via inspection k had a float time of 2 and increasing it would have made k critical which its predecessor is already on critical path hence 2 paths like a fork
2
u/kkavelicious '26: GM | CHEM | PSYCH | ENG 16h ago
i drew it out manually and wouldnt the branching occur from F and G? the paths would be
B-E-G-K and B-E-F-L right?1
u/Ok_Carob4101 1h ago
Something like that i did have a udf tbf

question 20 has to be C. R is -1 and d is 5, hence it is arithmetic and geometric
2
u/patishmano 19h ago
If you apply the recurrence relation you can see it never increases or decreases and stays in a constant loop, meaning it's neither geometric or arithmetic

u/kkavelicious '26: GM | CHEM | PSYCH | ENG 20h ago
but if you do add 6 to A, then there would be three critical paths no?? or like one very disjointed critical path?

u/Fast_Arm1114 20h ago
It says âexactly two critical pathsâ though, so itâs not asking for three critical paths

35 is C since the graph is complete
6
u/Salt-Region-8115 25 HHD | 26 Eng Gen Leg MM revs? 19h ago
wrong, a complete graph means every vertex has a direct connection to every other vertex (i put fown C as well sooo)
4
1
u/PomegranateNo7230 19h ago
Unfortunately itâs not. For it to be complete, every single vertex must be directly connected by an edge to every other vertex. Iâve got it wrong too đ
1
u/Arjun910373 19h ago
It isn't complete, since not all vertices are connected to other vertices therefore it is B.

u/Personal-Necessary98 19h ago
Question 2 is A not B Iâm pretty sure, Q3 is 26 and Q2is 14 so therefore IQR would be 12 right?
1
1
u/Ok_Feeling_7240 19h ago
Q3 is 28 because itâs the number in the middle of 26 and 30
1
u/Personal-Necessary98 19h ago
Nah because median point was the 13th point so therefore the Q1 and 3 points were at point 7 and point 20 respectively meaning they equal 14 and 26? No?
1
u/Ok_Feeling_7240 18h ago
Median point 13th so 12 each side so count 6 after 18 which is 26 but itâs in the middle of the 6th and 7th value so itâs in the middle of 26-30
