Variance is calculated by using the following formula: σ2=∑i=1n(xi−x‾)2Nwhere:xi=Each value in the data setx‾=Mean of all values in the data setN=Number of values in the data setσ2=N∑i=1n(xi−x)2where:xi=Each value in the data setx=Mean of all...
By Vieta’s Formula,a is the sum of the integral zeros of the function, and so a is integral. Because the zeros are integral, the discriminant of the function, a2−8a, is a perfect square, say k2. Then adding 16 to both sides and completing the square yields (a−4)2=k2+1...
