Webi=1 refers to the starting index, i.e. for a data set 1, 5, 7, 9, 12, i=1 is 1, i=2 is 5, i=3 is 7, and so on. The notation above essentially means to multiply each value in the set through the n th value, and then take the n th root of the product. Refer to the root calculator if necessary for a review of n th roots. Below is an example using ...

WebAug 2, 2015 · Explanation: x2 −6x + 6 The equation is of the form ax2 + bx + c = 0 where: a = 1,b = −6,c = 6 The Discriminant is given by: Δ = b2 − 4 ⋅ a ⋅ c = ( − 6)2 −(4 ⋅ (1) ⋅ 6) = 36 −24 = 12 As Δ > 0 there are two solutions. The solutions are found using the formula: x = −b ± √Δ 2 ⋅ a x = −( − 6) ± √12 2 ⋅ 1 = 6 ± √12 2 √12 = √2 ⋅ 2 ⋅ 3 = 2√3 x = 6 ± 2√3 2 Webx 2 − x − 6 = − x − 2 or x 2 − 4 = 0 ∴ x = ± 2 Clearly, x = 2 satisfies the domain of the equation in this case. So, x = 2 is a solution. Case II: x 2 − x − 6 ≥ 0 So, x ≤ − 2 or x ≥ 3 … Webthe given information to find the number of degrees of freedom, the critical values χ2L and χ2R , and the confidence interval estimate of σ.
