举一反三
- 设连续型随机变量X的概率密度函数为f(x),分布函数为F(x),则对任意实数a,( ) A: [img=134x25]18035d8b1ab1984.png[/img] B: [img=100x25]18035d8b22c648d.png[/img] C: [img=114x25]18035d8b2b21f9a.png[/img] D: [img=131x25]18035d8b33a2006.png[/img]
- 令F(x):x是有理数,G(x):x是实数。将命题“所有的有理数都是实数,但有的有实数不是有理数”符号化为() 未知类型:{'options': ['17e0a83a4157352.jpgx(F(x)∧G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)[img=14x9]17e0a73094b5dcf.jpg[/img][img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)[img=14x9]17e0a73094b5dcf.jpg[/img]G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)∧[img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)∧G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)∧[img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)[img=14x9]17e0a73094b5dcf.jpg[/img]G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)[img=14x9]17e0a73094b5dcf.jpg[/img][img=10x11]17e0a839b915354.jpg[/img]F(x))'], 'type': 102}

- 设F(x),G(x)都是函数f(x)在区间I上的原函数,则下面( )不正确 A: F(x)=G(x)+lnC B: F(x)=G(x)+C C: F(x)=G(x)-C D: F(x)=G(x)+e[img=9x12]180344b77e7e83a.png[/img]
- 二维随机变量(X,Y)的分布函数F(x,y),下面错误的是( ) A: [img=116x25]18038d36323e723.png[/img] B: [img=134x25]18038d3639fe9f5.png[/img] C: [img=120x25]18038d3641ba2cd.png[/img] D: F(x,y)是连续函数
