rip 50 dream

You just let the initial matrix be anything that totals 500 members. Eventually at steady state it will be the same matrix regardless of what the initial was.

I tried that. I must have mis entered my transition matrix in my rush or something because it didn’t work

Perhaps you are right. Nevertheless I have such confidence in 50 already being secured that I will not bring a bound reference into exam 2. Always up for an extra challenge.

Still take a bound reference just in case

can you still get a 48 or 49 or even 50 with 2 marks lost on exam 1 but 100% on exam 2?

yeh in the past people have got 49 with dropping 2 marks across both exams (2014) but it would all be dependent on how the top end of the state went on the exam.

Hey 505050 let us know if you get that 50 at the end of the year? cool & thanks
I, on the other hand, am looking forward to my 5 study score

What were we even meant to do for Q5 in matrices? V confused at where you're supposed to get the values from.

let a=costs associated with time, and let b=costs associated with distance
form 2 equations with the info they gave you
1 would be for judy: 8a+10b+2.55=16.75
2 would be for pat: 20a+18b+2.55=30.35
solving that gives a=0.4 and b=1.1
now for roy just sub in the values you just found. so 10(0.4)+15(1.1)+2.55
which is $23.05
hope that helps!

Thank you so much! That makes so much sense now!
