Can anybody please detail their explanation to this question!

Thanks.

Working's attached. Really you just need to repeat pythagoras' theorem a few times, but there might be a faster way that I neglected.

Hiya! If anyone could give me guidance on this question regarding one and two step dominance matrices, I'll repay you with a giant watermelon :']

Leanne has 1 two-step dominance, which implies that the person he dominates has 1 one-step dominance, which can only be Neil. Thus Leanne dominates Neil.

Ken has 2 one-step dominances and also 2 two-step dominances, which means that the two people he dominates each have 1 one-step dominance, which can only be Leanne and Neil. Thus Ken dominates Leanne and Neil.

Neil has 1 one-step dominance and 2 two-step dominances, which means he dominates either Ken or Maggy. We already established that Ken dominates Neil, thus Neil can only dominate Maggy.

Maggy has 2 one-step dominances and 3 two-step dominances, which means that one of the people he dominates has 1 one-step dominance and the other person that he dominates has 2 one-step dominances. We already established that Neil dominates Maggy so that means the only other person who has 1 one-step dominance that can be dominated is Leanne. And obviously the other person who has 2 one-step dominances is Ken. Thus, Maggy dominates Ken and Leanne.

Ok that sounds really confusing but it's much simpler when you actually think it through. Hope I helped.

Could someone please help me out with the attached questions? I'm not sure what formulas I'm supposed to be using

Thanks, guys!

Hmm for this don't you have to add your payment value to the 'extra value' and that will be ur final payment?
But if the question is asking for the 'extra payment' then I think C is correct

For this question attached i got the answer E, but answers say D who is correct ?

For this one, I think you are right. The Answers must be wrong

The answer for 7d is to be done separately. So it says after 2years. First find out what the flat rate depreciation would be (you already did this in part a). Your answer is $6000. So, it's saying that the value MUST be the same, meaning that the value has to be 6000. So just plop this in ur cas solve(6000=8400-0.25n,n) n will equal 9600. Meaning when the bike has travelled 9600 km, it's value will be the same as flat rate depreciation after 2 years.

How would you guys approach 2010 MC question 3
It basically asks for the standard deviation when it gives iqr and a boxplot

If you look at the histogram it looks like a bell curve meaning the normal distribution rule can be used. Your mean is 180, and 180 keeps increasing or decreasing by 2. Hence 2 is ur standard deviation.

For this question the answer should be C) 40km right ? not what the answers have (D)
