How many marks can one afford to drop across both Exam 1 and 2 combined for a 50?
Assuming 100% SACs of course.

I dropped 1 mark on SACs, none on exam 1 and 1 on exam 2 as far as I'm aware

can anyone help me with cuts in networks? It's really confusing me as I'm not sure how to find the maximum amount of cuts when calulcating flow and stuff (basically how do I know I'm not missing important cuts???)

Hey, I'd look into the exhaustion method for working it out (there's a few vids on youtube that explain it well). I would even do it for the ones where it said 'draw the cut' just to ensure I had the right one.

Also would recommend looking into this. In my experience, I haven't ,met a single student who had learned this method in class, yet it makes finding the maximum flow so much easier.

I found this much more time consuming, I prefer doing it all in my head (everyone's different i guess).

But this method is definitely useful if you have enough time when double checking your answers.

Anyone got some good tips and tricks for graphs and relations module?
Particularly Linear Programming.

Particularly Linear Programming.

The sliding rule method is generally glossed over in textbooks, but it is the conceptual basis for the corner point method, and it is often assessed in multiple choice questions. Do not neglect it.

What I would do for this (and there may be another, easier way), is to find the 'quarterly average' by adding all of the 'long term average' values together, and dividing it by the number of days of the week (7) (89+93+110+132+145+190+160/7=131.285714286). After this, divide the value for Saturday by the quarterly average (190/131.285714286=1.44722524483, which can be rounded to 1.45). Therefore, the answer is D.

Sorry, hope that wasn't too confusing!!!

Or, calculate the seasonal average using one of the day's long-term average and seasonal indices. For instance, using Monday's values we get that the seasonal average is 89/0.68 = 131. So Saturday's seasonal index is 190/131 = 1.45.

Can someone explain question 9 and 10 on data analysis 2017 further exam 1?

Thanks.

I'm assuming this is for VCAA 2017 Exam 1? I won't provide the answers, but the thinking process very briefly.

VCAA 2017 E1 Data Analysis Q9 and Q10

Q9. Start by finding the point they're indicating and note whether the point is above or below the line. Below indicates negative and above is positive. Then use your ruler to define the difference between point and line.
Q10. Another word for standardised value is z score. Sound familiar? This should give you the formula you need (also found here). Plug in the numbers for the point given, the mean and the St Dev into your calculator and that should give you the right answer.

Does that help?

Is this still on the study design? (Q3 2006 exam 2)

If it is how would I go about doing it? This is also on exam 1 I think (or maybe it was 2007 exam 1). I know how to do 3 median smoothing but I've never had to get an equation from it. The provided solutions say to use 3 points but I don't know how I'm supposed to figure out which points to use?

Three median line is not on the study design, you can skip those questions.
