Hmm...for that question I remember putting down C and I checked it twice or thrice in the remaining 30-40 minutes that I had after finishing the paper.

 

[rowdyroddy]

i found maths pretty easy,
lol school certificate

i stuffed up my equation i didnt write it properly...the tile one with 1980 and 10 percent the equation i did was

178.2/0.09=1980

the original area was 162 and 10 percent of that is 16.2 so 162+16.2=178.2
and the m^2 of the tile is 0.09 soo....

178.2/0.09=1980

that was my equation

what was the answer for the rectangular prism being cut through a line and they had 2 diagrams on it .... i guessed it.. AH -(B)

at the time all answers looked right =(

the answer was the one cut from the top diagonal to the other cause the base needed to be 4 so you would have rolled the prism towards you to cut diagonally, or cut from the top oppostie corners...if that makes sense
i tink it was CH or something like that

One of the questions about integes really confused me!

It was like: Which one of the following is ALWAYS TRUE:

1) a positive minus a positive is a negitive

2) a negitive plus a positive is a positive

3) ........

4) ........

NONE OF THEM WORKED!

Translation is just moving the triangle.

I didn't know what it was, and I worked it out o__O
I mean seriously, if it wasn't flipping or rotating, what is the ONLY other movement that can be made on the triangle...

I thought it meant you both flipped and rotated it

Nope, the fourth one worked. If I remember correctly, the fourth one went something like when a negative no. is subtracted from a positive no. and gives a positive answer. Basically, this one's right because if a negative no. is subtracted, the no. turns into a positive integer. Remember, a negative and a negative gives a positive. But yeah, this question wouldn't make sense to many because of the wording of the answers.

 

[Hayzazz]

That question kinda stumped me as well... until I re-read the question and the choices like 3-4 times over ^_^"

Yeah it was that one.

what was the answer to that question about the rectangle's area on the number plane?? i put 8, but idk if its right

i put 8 as well.... i think.. but i put B for sure
you had to use the equations of the lines and properties of a rectangle like equal sides and stuff :|

what did people put for the question about
whats her name being 30 years old. and in 10
years she'll be 20 years younger than william.

[miss giggles]

what did you guys put for the question that said what which information would benefit the shop owner the most the :mode,median or mean to see what glove size he should manufacture
:jaw:

I put mean because the mean is basically the average and most people fit into the average category.

i found that hard as well but i ended up putting a negative number subtracted from positive gives positive as i thought you could do something like 3-(-4)=7

i put MODE as it occurs the most often...and mean isnt really correct the mean for one wouldnt be a whole number and it doesnt really help him

Yeh, i put this too.

 

[maths94]

Yeh, i put this too.

lol sikk i feel assured i got it correct wen ppl ..say im correct to

yes the fourth one worked, it was weirdly worked but it ended up being like "X--Y" which would be a positive.

Mode, its the most common size among the population. Mean takes in account of outliers which would be foolish and all other options would just be dumb to consider xD.

 

[Mythril]

However, the mean is the central tendency of the entire population meaning that most of the population would be between that category, give or take one, and plus if it's a decimal you either round it up or down and I can't remember if there was any outliers in the question. But if I did get it wrong, oh well, it's only one and so far i've gotten everything all right

 

[Reptave]

I put the mode in, because most people use that glove size.
