1 Answer1 Based on the comments, I assume the that the X in part 1 and 2 is the same Then we know E X = 1, V a r ( X) = 4 You may now find the answer by using the relationship V a r ( X) = E X 2 − ( E X) 2 ( Hint The correct answer is 41) I leave the below as an example of why the information in the first part is not sufficientNews, The Soup, Chelsea Lately, and more!Get stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us!

E x 22

E x 22-Then E (X) is computed, squared, and subtracted (once) from E (X 2) 18 Rules of Variance The variance of h (X) is the expected value of the squared difference between h (X) and its expected value V hLet X i be 1 if the ith trial is a success and 0 if a failure Note that E(X i) = 0 q 1 p = p Our binomial variable (the number of successes) is X = X 1 X 2 X 3 X n so E(X) = E(X 1) E(X 2) E(X 3) E(X n) = np What about products?

In Probability theory and statistics, the exponential distribution is a continuous probability distribution that often concerns the amount of time until some specific event happens It is a process in which events happen continuously and independently at a constant average rate The exponential distribution has the key property of being memoryless(e^x)^2 = (e^x) (e^x) = (e)^ (2x) means that e is first raised to the power x and then to power 2 and as such e^x^2 is not generally equal to (e^x)^2\dfrac{\sqrt{\pi} }{2 } {/eq} Its numerical value is obtained by multiplying it to

Differentiate y = (e √ x21)/(x2 1) Be sure to show all steps and justify each step Question Differentiate y = (e √ x21)/(x2 1) Be sure to show all steps and justify each stepThe mean, or first moment, of a distribution is a measure of the average Suppose that a random variable has three outcomes To calculate the mean of X, we compute E (X) That is, The variance of X is calculated as E (X X) 2 We can augment our table as follows Now, we take E (X X) 2 Suppose that the values of X were raised to 4, 6, and 13The partition theorem says that if Bn is a partition of the sample space then EX = X n EXjBnP(Bn) Now suppose that X and Y are discrete RV's If y is in the range of Y then Y = y is a event with nonzero probability, so we can use it as the B in the above
