# Mathematics: Post your doubts here!

The data in which we were supposed to make box and whisker plot wasn't arranged? Really?

Yes not arranged. That question is the only one I have got wrong so far in maths alevel exams. Probably gonna cost me my distinction...

Ouch sorry man
Thing is I did check if they were arranged but I guess I did that wrong? lol

#### Kanekii

I literally checked the first and last row to check if it was arranged seems like it was not arranged in the middle row.
Btw for the combination question what if we used factorials instead like:
6!/3!*2!*1! would that be correct or still wrong.

The question we were supposed to make box and whisker plot, what was the last part of it? Did it ask us to write down the median and quartiles?

#### blymphocytes

Yes sadly it was. The lower quartile was 256.5 - if you assumed that the data was arranged then your lower quartile would have been 256.
omg nooooooooooo

They had given space above the box and whisker plots to do working to find median and the quartiles so you should have shown some sort of working that would give you a mark or two.

Who knows you may still be able to get one!

When doing this through simulatenous equation i am not getting correc tanswer why?

#### blymphocytes

I had a question though......why are you not doing ln y^3??

In order to apply logarithm on 1/y^3 the derivative of y^3 should be present in the numerator then we can use it.

In order to apply logarithm on 1/y^3 the derivative of y^3 should be present in the numerator then we can use it.
Oh ok.....so for example it was 2/y^3.........we could write this as 2ln(y^3)

No ....derivative of y^3 is 3y^2 this should be present.
