Draw it from a table! Example-frequency, and make cf -Drawing graph? Use crosses to plot, connect them. |
|
|
Box plots? |
- Plot 'whiskers' lowest & highest value - Plot box with lower& upper quartile and median - interquartile range= upper - lower quartile |
|
|
Recurring decimals to fractions? |
Steps: - let x = recurring decimal (x= 44.44' - × 100 (100x = 44.44..) - minus two equations (100x=44.44..- x = 0.44..) - x= 44 ÷ 99 - try to simplify |

|
Equation of a circle? |
X* + y* = r*
- if it says draw circle from equation? Reverse; *root r for radius - if it says show a point on a circle? Plug x & y values into equation - If it says find equation of circle shown? Use pythag

|
Adding Fractions? |
-Make bottom numbers the same, - Find LCM (lowest number they both go into) then x top numbers too - add top numbers
2 3 5 × 4 = lcm is 20. ×4 ×5 8/20 15/20 = 23/20 |
|
|
Dividing Fractions? |
-flip 2nd fraction (find reciprical) Then work out as if adding fractions
- if 2nd fraction is a whole number, ie 8 it = 8/1
- with mixed numbers, convert to top heavy fractions then flip 2nd
