3.设函数$f(x)={{x}^{4}}\sin x$,则${{f}^{(9)}}(0)=$（ ）。 A: $\frac{9!}{5!}$ B: $\frac{5!}{9!}$ C: $\frac{1}{5!}$ D: $0$

假设x=4,y=2,m=5,n=4,w=12,t=9，则经过表达式（w=x 0
9

有代码片段：function f(y) {var x=y*y;return x;} for(var x=0;x< 5;x++) {y=f(x);document.writeln(y);}输出结果是( )。 A: 0 1 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: 0 1 2 3 4 5

a=[4,-1,2,-4,-9],执行命令[x for x in a if x>0]的返回值是()

阅读下面的JavaScript代码，输出结果是function f(y) {var x=y*y;return x;}for(x=0;x<; 5;x++) {y=f(x);document.writeln(y);} A: 0 1 4 9 16 25 B: 0 1 2 3 4 C: 答案都不对 D: 0 1 4 9 16

同时掷2颗均匀骰子，X表示点数大于4出现的个数，则以下结果正确的是 A: X服从二项分布 B: P(X=0)=P(X=1) C: P(X=1)=4/9 D: P(X=0)=1/9 E: P(X=2)=4/9 F: P(X>;0)=1 G: P(X<;2)=5/9 H: P(X>;1)>;0.5

阅读下面的JavaScript代码,执行结果为?function f(y) { var x = y * y; return x;}for(x = 0; x < 5; x++) { y = f(x); document.write(y+" ");} A: 0 1 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: 以上答案都不对

[1, 3, 0, 2; -2, -5, 7, 4; 1, 0, 9, 5; -1, 0, -9, -5] C. [1, 3, 0, 2; -2, -5, 7, 4; 3, 5, 2, 1; -3, -5, -2, -1] D. [1, 3, 0, 2; -2, -5, 7, 4; 0, 0, 0, 1; -1, 0, -9, -5]

&gt;&gt;&gt;x= &#91;10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9&#93;&gt;&gt;&gt;print(x.sort()) 语句运行结果正确的是( )。 A: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] B: [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9] C: [10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0] D: ['2', '4', '0', '6', '10', '7', '8', '3', '9', '1', '5']

Read the following JavaScript code: function f(y) { var x=y*y; return x; } for(x=0;x&lt; 5;x++) { y=f(x); document.writeln(y); } The output is ( ). A: 01 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: None of the above answers are correct
