设X服从均匀分别U[2,4],Y服从指数分布e(2),且X与Y相互独立。 求(1)(X,Y)的联合概率密度; (2)E(2X+4Y);(3)D(X-2Y)。 答案解析 (简答题) 设随机变量X,Y都在(0,1)上服从均匀分布,且X,Y相互独立,求Z=X+Y的概率密度。 答案解析 (简答题) 设X,Y相互独立,且X服从数学期望为150,方差为9的...
lambda^2 - 5lambda - 6 = 0 解得：lambda1 = 3.618033988749895, lambda2 = 1.381966011250105 因为特征根实部均为负数，所以该方程组的零解是稳定的。
If the line y=3x+lambda touches the hyperbola 9x^(2)-5y^(2)=45, then the value of lambda is
An equation which is of the form {eq}ax^2+bx+c=0 {/eq} where {eq}a, b \text{ and } c {/eq} are constants is called a quadratic equation in {eq}x {/eq}. It has two (either same or distinct) roots. The roots can be solved by using the quadra...
