The independent variables for two equations of the given problem are randθ . We have to find the derivative of dependent variable y with respect to r and θ. Before applying derivative with respect to independent variables, we will convert logari...
In other words, the random variables X and Y are independent if P(X=x0∧Y=y0)=P(X=x0)P(Y=y0) for values x0 and y0. A common test for determining whether two variables are dependent is to calculate t...
Answer to: Assume X and Y are independent random variables, each uniformly distributed over the interval (0, 1). Find E(X/Y). By signing up, you'll...
How do you find (h - g)(t) given h(t) = 2t + 1 and g(t) = 2t + 2? Arithmetic Operations with Functions: Functions are relations of two variables, where one is the independent variable and the other is the dependent variable. We can perform multiple mathematical op...
Solution method: The method of solution is based on a Darboux/PS-type approach Restrictions: If, for the ODE under consideration, the Darboux polynomials are of high degree (>3) in the dependent and independent variables, the package may spend an impractical amount of time to obtain the ...
a按自变量对因变量的贡献由小到大的顺序依次引入方程, Introduces the equation in turn according to the independent variable to the dependent variable contribution from small to big order,[translate] aMoisture and water content 湿气和水含量[translate] ...
Let X1 and X2 be independent Poisson random variables with parameters λ1 and λ2.Show that for every n ≥ 1,the conditional distribution of X1,given X1 + X2 = n,is binomial,and find the parameters of this binomial distribution.

Let X and Y be independent random variables with means μx, μy, and variances σx2, σy2. Find Cov(X,X+XY). Covariance: The covariance is the measure by which the relation between the two can be checked. If the covariance is zero...
The variable whose value is dependent on another variable is called the dependent variable.Answer and Explanation: Let the two variable be X andY resoectively E(XY)≠E(X)E(Y). It is only possible when these two variables are not independent Let......
