(A)3x (B)sin x (C)x3 (D)x+ 解析:由题意得,函数满足 f(-x)+f(x)=0, 即 f(-x)=-f(x),所以函数 f(x)为奇函数. 又 f(x+m)>f(x), 则函数 f(x)应为实数集 R 上的单调递增函数, 只有函数 f(x)=x3 满足条件,故选 C. 7.(2012 郑州质检)给出 30 个数:1,2,4,7,11,…,要计算这 30 个数的和,现已

(2)睡眠时间小于 8 小时的频率是 p=0.04+0.26+0.30+0.28=0.88. (3) 首 先 要 理 解 题 中 程 序 框 图 的 含 义 , 输 入 m1,f1 的 值 后 , 由 赋 值 语 句:S=S+mi·fi 可知,流程图进入一个求和状态,令 ai=mi·fi(i=1,2,…,6),数列 {ai} 的 前 i 项 和 为 Ti, 即

T6=4.5×0.04+5.5×0.26+6.5×0.30+7.5×0.28+8.5×0.10+9.5×0.02=6.70, 则输出的 S 为 6.70. S 的统计意义是指参加调查者的平均睡眠时间. 22.(本小题满分 14 分) (2012 年高考安徽卷)若某产品的直径长与标准值的差的绝对值不超过 1 mm 时,则视为合格品,否则视为不合格品,在近期一次产品抽样检查中, 从某厂生产的此种产品中,随机抽取 5000 件进行检测,结果发现有 50 件 不合格品,计算这 50 件不合格品的直径长与标准值的差(单位:mm),将所 得数据分组,得到如下频率分布表: 分组 [-3,-2) [-2,-1) (1,2] 8 0.50 频数 频率 0.10
