A fair coin just means 50% heads 50% tails. so the sample is still 50% heads 50% tails.
900x300=270,000 plus 2 would equal 270,002.4 devided by 3-2001 would equal 87,999.8
The quadratic formula is above.
You want each equation in standard form: ax^2 + bx + c = 0
I begin each problem by defining variables.
For instance 3. Is in standard form. X^2 -2x - 3 = 0. a = 1, b = -2, c = -3
Now use quadratic formula: x = [- b + or - sqrt(b^2 - 4ac)]\2a
