The Greatest Card Trick in the world

I posted this because it relates to the card unit and probability unit in the maths dimensions book.

Pretty cool Card trick!

Conduction, Convection and Radiation

Mean

The mean is the average of a group of numbers altogether.

For eg.

1,4,6,3,7,9,

Add them together, so

= 30

Then divide it by the amout of numbers, in this case it is 6, so:

30/6 = 5

The average number is 5.

Graphing

Today we learnt about Graphs and how to interpret line graphs.

If you wanted to compare the temperature in May from October, you would need to find out the two different temperatures:

May: 22 Degrees C

October: 24 Degrees C

=24-22

=2 Degrees

So therefore October is two degrees warmer than May.

You could interpret it as October warmer than May, or May Colder than October.
