Web2 okt. 2024 · We could use one of the inverse properties of exponentials and logarithms listed in Theorem 6.3 to write 129 = 2log2 ( 129). We’d then have 2x = 2log2 ( 129), which means our solution is x = log2(129). This makes sense because, after all, the definition of log2(129) is ‘the exponent we put on 2 to get 129 .’.

WebTo find E[ f(X) ], where f(X) is a function of X, use the following formula: E[ f(X) ] = S f(x)P(X = x) Example. For the above experiment (with the die), calculate E(X 2) Using our … WebIf we think of W 1 as the number of trials we have to make to get the ﬁrst success, and then W 2 the number of further trials to the second success, and so on, we can see that X = W 1 + W 2 + ... + W r, and that the W i are independent and geometric random variables. So E[X] = r/p, and Var(X) = r(1−p)/p2. 5 Poisson random variables bleach 342 vostfr
