Web1 Answer Sorted by: 15 The symbol × is used to denote the "Cartesian Product" of two sets: it results in a set with ordered pairs. The Cartesian product (some call it the "cross product" of sets) X × Y is defined such that X × Y = { ( x, y) ∣ x ∈ X, y ∈ Y } I'll get you started: B × … WebWe can combine means directly, but we can't do this with standard deviations. We can combine variances as long as it's reasonable to assume that the variables are independent. Mean. Variance. Adding: T = X + Y. T=X+Y T = X + Y. T, equals, X, plus, Y. μ T = μ X + μ Y.

WebThe assumption that the observations are statistically independent means that P ( x A, x B) = P ( x A) P ( x B), which trivially satisfies the above integral relationships as N 1, N 2 are normalized. So to answer your initial question, the correct answer is N 1 N 2. An illustrative example is the standard 52-card deck. The standard playing card ranks {A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2} form a 13-element set. The card suits {♠, ♥, ♦, ♣} form a four-element set. The Cartesian product of these sets returns a 52-element set consisting of 52 ordered pairs, which correspond to all 52 possible playing cards. Ranks × Suits returns a set of the form {(A, ♠), (A, ♥), (A, ♦), (A, ♣), (K, ♠), …, (3, ♣), (2, ♠), (2, ♥…

WebWe can use the following formula, where the number of permutations of n objects taken k at a time is written as nPk. The factorial notation (!) is also defined below. where x! = x ( x – 1) ( x – 2) . 2 1 To understand how we get this formula, first consider the case where we want to find how many ways we can order all n objects.

WebHowever, the difference between them is much bigger (20 now), because multiplying by the same number doesn't mean that you are adding the same thing. 5 x 4 = 4+4+4+4+4, and 5 x 8 = 8+8+8+8+8. So, if we imagine that 4 is the mean in the original set, and 8 is another data point called X, X is now a lot farther away after scaling it (remember ...
