wasnt the residual value -752 :S

i thought there was only 1 country (norway with over 50%)

i did that and then re red question and found out i was wrong.

wasnt the residual value -752 :S

did u have to say redidual i just said there was a x amount of difference

[claire92]

Can anyone answer this

For trig, one of the questions on the volume of pyramid was two marks, I used eactivities to solve this to get 1.47, which i confirmed with others was right, but I just wasn't sure how to solve it normally

so by putting 1.47, will I get the question wrong, or just get one mark?

Also
Found this easier than exam one, but I think I made some silly mistakes.

i think they will be hunting for that negative value.

[karar]

no, the value was 752 UNDER THE REAL VALUE. this means the dot was above the line. making it a positive

volume= (1/3)*area of base* height
1.8=(1/3)* area of base* 2.5
(1.8*3)/2.5 = area of base
2.16= area of base
2.16= area of base = x^2
2.16=x^2
square root 2.16 and you get 1.47

isnt 2c cause it was extrapolating the value so it was unreliable?

[Studyinghard]

I wrote that aswell ^^

[doter]

What was the residual question? Don't remember there being one  

[physics]

core 1d... wouldnt it be because there are no outliers D:

[slee]

it said the error in the prediction
so I said -752 too..... so im wrong?

[physics]

i didnt know they were asking for the residual value :S i thought they were asking for the source of error which i said was because they used 28 intead of 27.
