It seems like it's $6.50 as per this link --> https://educationstandards.nsw.edu....esults-certificates/results-services-students, but I may have misinterpreted it.

why does nesa make it so confusing. So they wanna rob us money yet they make it hard to understand

is anyone actually willing to buy

 

[specificagent1]

yeah i’ll buy it to help database

good on ya

they're such pussies ngl

Like I said Sydney Morning Herald frequently tried to play the victim card. Especially given what they do everywhere from Dave Elliot, John Barilaro with the Friendlyjordies case etc.

piss off with that question mate

 

[Greninja340]

For part B is it its meant to be 1-(P(0.1)+P(0.2)+P(0.3)+P(0.4)) right? cause it says greater than Z=4? Is this correct or were you not meant to subtract P(4) from 1?

Does anyone know how the moderating would work this time for advance maths???? Or maybe what would likely be a cut-off mark for a band 6?

Think so, although I don't remember the z score exactly

 

[stupidpersonlol]

ppl released the solutions to the task guys- what did yall roughly get

 

[stupidpersonlol]

nightmare

I got b, (1/2pi)<m<(1/a), not sure about this one tbh

You are correct

The answer to q10 in this is wrong. It is B. When , the line is at and the -coordinate must be between 0 and 1, so we have that .

The probability you are looking for is P(Z>0.4). The table only gives you P(0 < Z < 0.4), so you're missing half the entire normal curve. This means you need to do a bit of manipulation first
P(Z > 0.4) = 1 - P(Z < 0.4) = 1 - [0.5 + P(0<Z<0.4)] ~ 0.5 - 0.1554 = 0.3446

The answer in the attachment is wrong. You cannot have more than half of the babies being above the average for a normal distribution.

i hope like 60% raw is band 6 lol

who knew the eng exam would be easier than the math one

TOLD YOU, I HAD A FEELING MATHS WOULD BE TRAGIC AND IT WAS
