IGCSE Math - Bearing
« on: August 30, 2010, 01:34:34 pm »
Hiii .
I need something to read from about Bearing. I dont understand it. I mean I understand that it is checked from a clockwise point and all the stuff... but those questions on the past papers need different concepts ? Does anyone have a link to learn Bearing that can help me for IGCSE?

Post some questions you got wrong and I'll help you out.

Its the same basic concept as in your textbook. However, there are some tricks.  ;)

Use the graph to find P and Q then input it into the table.

Next for ii  find the middle value of each class interval (in blue below).

Multiply the Middle Value to its corresponding frequency :

5 x 12 = 60

15 x 34 =  510
etc.

You see the above values in red ? Add those up to get 7220 and divide it by 200 (just add 12+ 34+ 36+ 30+ 38+ 30+ 16 + 4)

You will get a mean of 36.1 I think.

Is that correct ?
