[Further Maths] Understanding a Matrices Question in the Heinemmann Book

[Branson, Steven S]

>From adult to die is only 4% rather than 8% because 4% of the adults become children (8% - 4% = 4%). The remaining 4% is from adults to children- after all we can't have children coming back from the dead. So in answer to your question, the rest of the adults became children again.

Subject: [Further Maths] Understanding a Matrices Question in the Heinemmann Book

Hi All,

My colleague and myself have been having trouble with a question in the Further Maths Heinemann Enhanced Edition,
and would like to request some please.
9.6 worked example and question 1.

[cid:image001.png at 01CC62A3.B3F2D910]

Final matrix
[cid:image002.png at 01CC62A3.B3F2D910]

8% of adults died. In the final matrix 3rd column 4th row, 4% of the dead adults is placed.
My question is what happened to the other 4% of dead people to total 8%.
I'm thinking that it should be 0.08 instead of 0.04.

WHERE HAVE ALL THE DEAD PEOPLE GONE!!! PTL!

Final Answer for n  = 1

Regards

Mr Hem
