For the density function f x 2x/9
Did you know?
WebLet X be a continuous random variable whose probability density function is: f ( x) = 3 x 2, 0 < x < 1 First, note again that f ( x) ≠ P ( X = x). For example, f ( 0.9) = 3 ( 0.9) 2 = 2.43, which is clearly not a probability! In … WebA CDF function, such as F (x), is the integral of the PDF f (x) up to x. That is, the probability of getting a value x or smaller P (Y <= x) = F (x). So if you want to find the probability of rain between 1.9 < Y < 2.1 you can use F (2.1) - F (1.9), which is equal to integrating f (x) from x = 1.9 to 2.1. ( 17 votes) Show more... tarjeism
WebOn a randomly selected day, let X and Y , respectively, be the proportions of the time that the drive-in and the walk-in facilities are in use, and suppose that the joint density function of these random variables is. f(x,y)=\left\{\begin{array}{lc}\frac{2}{ 5}(2x +3y), & 0 ≤ x ≤ 1,0 ≤ y ≤ 1, \\0, & elsewhere.\end{array}\right. WebDensity = mass/volume = 12 grams/8 cm 3. So, it comes out to be = 1.5 grams/cm 3. Hence, this sugar cube has a density of 1.5 grams/cm 3. Q2. A particular solution of salt …
WebSuppose that X and Y have a joint probability density function f(x,y)= 1, if0<1,y<2y; 0, otherwise. (a) Compute P(X + Y less than or equal 1). ... If the probability density of X is given by f(x) =kx3(1 + 2x)6 for x > 00 elsewhere where k is an appropriate constant, find the probabilitydensity of the random variable Y = 2X 1 + 2X . Identify ... WebThe density function has infinite negative slope at x = 0 if 0 < k < 1, infinite positive slope at x = 0 if 1 < k < 2 and null slope at x = 0 if k > 2. For k = 1 the density has a finite negative slope at x = 0. For k = 2 the density has a finite positive slope at x = 0. As k goes to infinity, the Weibull distribution converges to a Dirac delta ...
