The answer is (B), I believe. For these three-point median regression lines, we have to divide the data into three 'clumps', consider a line connecting the medians of the outer two clumps, and then move this one-third of the way towards the median of the inner clump.

The l=r\theta isn't actually on the formula sheet, so you are just talking about general mathematics, unless that formula was given to you to use, then I'd doubt you'd be required to do it.
He might be talking about 2U Maths, since this looks like a typical 2U question (calculating arc lengths of circles).The l=r\theta isn't actually on the formula sheet, so you are just talking about general mathematics, unless that formula was given to you to use, then I'd doubt you'd be required to do it.

I've seen it used in General Mathematics papers a lot of times tooHe might be talking about 2U Maths, since this looks like a typical 2U question (calculating arc lengths of circles).
(He might have meant to put this in his other maths thread but put it here by mistake).
Yeah, it probably is a General Maths Q.I've seen it used in General Mathematics papers a lot of times too
This was from the 2012 General Maths HSC Exam Paper as well.He might be talking about 2U Maths, since this looks like a typical 2U question (calculating arc lengths of circles).
Edit: oh wait, never mind, there's a formula for when the angle is in degrees in the General Maths formula sheet. So it is probably a General Maths question.
