It was to be 16b^6/a^2 but i took square root of both :/

Do you remember the question?

 

[Abdul Hanan]

yes

About the frequency polygon, did we have to join it to x axis. I didn't. :/

 

[Awesome12]

No, mine was different. 16 as numerator.

Yeah you had to take the reciprocal. Also wasnt a at the botttom I think, or was it b?

Yeah I got the same, but I dont think the square root was required

I dont remember. But i did take reciprocal and convert -2 to 2. Then 4 was squared.
And the others too.. But i don't remember :/

Are we wrong here?

 

[Dark Destination]

What about distribution one? Boys or Girls?

 

[asadalam]

WHAT ? The polygon was of BOYS, while the comment was that 'The girls had less spread compareD to boys :

We needed to draw 2 polygons.

No its right.

a was at the bottom

Boys times were more distributed. I wrote that. :/ Will i get the mark?
What was the answer?

More evenly would be right,i wrote girls had a more concentrated frequency and 19/20 were in 3 class widths while boys were more evenly distributed.

Yes, i wrote a long paragraph mentioning that the times of boys were more widely spread, and more distributed, while girls were concentrated from __ to ___ time interval. And also mentioned that for some time intervals, the frequency of girls was 0.. and blah blah..

I think we didn't have to join the polygons. We only have to join them when there are empty classes on sides. Like here:

What was the answer to the shading of square to get 2 lines of symmetry

Really? But their weren't empty spaces their on the left and right?

Right?

Right?

Maybe.Any other answers youd like to share

You didn't get the same? :/

Well... for that rotational symmetry one, it was 3 and 0 right?

And speed time graph --> v/25
Next -- v = 10

Next - 108..

OMG, I thought it was for boys
