WebGiven the following joint density function: f ( x, y) = { c ( x + y) 2 0 ≤ x ≤ 1, 0 ≤ y ≤ 1 0 otherwise I need to find the value of c. From my answer sheet, I know that the answer is 6 …
WebDefinition Two random variables X and Y are jointly continuous if there exists a nonnegative function f X Y: R 2 → R, such that, for any set A ∈ R 2, we have P ( ( X, Y) ∈ A) = ∬ A f X Y ( x, y) d x d y ( 5.15) The function f X Y ( x, y) is called the joint probability density function (PDF) of … fix gap in bathtubWebAbout this tutor ›. 6sin (π/2⋅x) = 3. sin (π/2⋅x) = 1/2. From the unit circle, the sine values that equal 1/2 have the solution set x = π/6+2πn, 5π/6+2πn. π/2⋅x = π/6+2πn, 5π/6+2πn. x = 1/3+4n, 5/3+4n. Since we are looking for the 4 smallest positive solutions, we would need to plug in n=0 and n=1: x = 1/3+4 (0), 5/3+4 (0) can money from a trust be taxedWebThere is probably a simpler or more computationally efficient way, but this solution is fast enough for what you may be trying to do.
