-Pie charts are used to illustrate relative sizes of particular categories -Take the frequency of each category and scale it up to 360 degrees-Give an example to demonstrate e.g. colours of cars

to solve a quadratic we can use the quadratic formula: (-b+_sqr(b²-4ac))/2a
y=x²+5x+6
a=1b=5c=6
to get x=3 or x=2

Firstly based on the Pythagoras Theorem which claims that the square of the hypotenuse is equal to the sum of the squares of the other two sides, we will find the hypotenuse of the first triangle. To make...

16.7% or 1/6.The combinations for (dice 1, dice 2) which total 7 are: (6,1), (5,2), (4,3), (3,4), (2,5), (1,6).Total possible cocmbinations = 36.Hence 6/36=1/6=0.166... or 16.7%

This question is an example of expanding algeba and equating coefficients. If the brackets on the left-hand side are expanded the unknown values can be found from the coefficients on the right-hand side.S...
