4.写出下列随机变量可能取的值,并说明随机变量所取的值表示的随机试验的结果.(1)一个袋中装有8个红球,3个白球,从中任取5个球,其中所含白球的个数为X.(2)一个袋中有5个同样大小的黑球,编号为1,2,3,4,5,从中任取3个球,取出的球的最大号码记为X.(3). 在本例(1)条件下,规定取出一个红球赢2元,而每取出一个白球输1元,以ξ表示赢得的钱数,结果如何?[解] (1)X可取0,1,2,3.X=0表示取5个球全是红球;X=1表示取1个白球,4个红球;X=2表示取2个白球,3个红球;X=3表示取3个白球,2个红球.(2)X可取3,4,5.X=3表示取出的球编号为1,2,3;X=4表示取出的球编号为1,2,4;1,3,4或2,3,4.X=5表示取出的球编号为1,2,5;1,3,5;1,4,5;2,3,5;2,4,5或3,4,5.(3) ξ=10表示取5个球全是红球;ξ=7表示取1个白球,4个红球;ξ=4表示取2个白球,3个红球;ξ=1表示取3个白球,2个红球.
温故知新 1.离散型随机变量的定义可能取值为有限个或可以一一列举的随机变量,我们称为离散型随机变量.通常用大写英文字母表示随机变量,例如X,Y,Z;用小写英文字母表示随机变量的取值,例如x,y,z.随机变量的特点: 试验之前可以判断其可能出现的所有值,在试验之前不可能确定取何值;可以用数字表示2、随机变量的分类①离散型随机变量:X的取值可一、一列出;②连续型随机变量:X可以取某个区间内的一切值随机变量将随机事件的结果数量化.3、古典概型:①试验中所有可能出现的基本事件只有有限个;②每个基本事件出现的可能性相等。二、探究新知探究1.抛掷一枚骰子,所得的点数X有哪些值?取每个值的概率是多少? 因为X取值范围是{1,2,3,4,5,6}而且"P(X=m)"=1/6,m=1,2,3,4,5,6.因此X分布列如下表所示
1.确定研究对象,明确哪个是解释变量,哪个是响应变量;2.由经验确定非线性经验回归方程的模型;3.通过变换,将非线性经验回归模型转化为线性经验回归模型;4.按照公式计算经验回归方程中的参数,得到经验回归方程;5.消去新元,得到非线性经验回归方程;6.得出结果后分析残差图是否有异常 .跟踪训练1.一只药用昆虫的产卵数y与一定范围内的温度x有关,现收集了6组观测数据列于表中: 经计算得: 线性回归残差的平方和: ∑_(i=1)^6?〖(y_i-(y_i ) ?)〗^2=236,64,e^8.0605≈3167.其中 分别为观测数据中的温度和产卵数,i=1,2,3,4,5,6.(1)若用线性回归模型拟合,求y关于x的回归方程 (精确到0.1);(2)若用非线性回归模型拟合,求得y关于x回归方程为 且相关指数R2=0.9522. ①试与(1)中的线性回归模型相比较,用R2说明哪种模型的拟合效果更好 ?②用拟合效果好的模型预测温度为35℃时该种药用昆虫的产卵数.(结果取整数).
尊敬的老师,亲爱的同学们:大家上午好!我是来自xx班的。今天我国旗下讲话的题目是:独立个性对我们来说很重要。不知道大家对独立个性这个词语有怎么样的理解,我的第一反应是不依赖父母,自己的事情自己做。的确这是独立的基本大意,但独立个性好像不单单只是这样。对于一个具有独立个性的人来说,对自我价值的认可至关重要。每一个人都是一个独特的个体,每一个人的个性都有独特的一面。具有独立个性的人不仅是行动上的独立,更有思维上的独立;具有独立个性的人不会为自己的利益去做驾驭他人的事,不以自己的意志去束缚任何人,虽然以自我为中心,但却能尊重他人的意志和思想。拥有独立个性对自身来说也是终生受益。在我们的生活中,你是不是常常会发现有这样的同学。老师分享了一种学习方法,他就原样照搬,不顾自己的实际情况盲目实行,最后浪费了时间、精力,却收不到成效。
三峡库区农村移民安置根本出路是通过发展大农业来解决耕地不足,不应盲目开垦荒坡地,防止产生新的水土流失,尽量避免生态环境恶化。2、就地后靠,就近安置模式三峡库区淹没区线状分布的受淹特点有别于一般水库淹没区的片状分布,使得库区移民具有相对分散的特点,且淹没涉及的356个乡镇没有一个被全淹,甚至全淹的村也很少,这有利于移民在本县甚至本乡就近后靠安置,避免了水库移民大量外迁、远迁所造成的种种困难和后遗症。三峡移民搬迁大多可以就地后靠,就近安置,这是三峡移民的一大特色。就近后靠安置的优点是不离本乡本土,移民容易接受,且避免了移民大量外迁、远迁所造成的困难和后遗症;缺点是容易对当地的生态环境造成过大的压力,如过度开垦坡地、破坏植被、加剧水土流失等。3、工程周期长,可从容安置移民三峡工程建设周期长(1994年~2009年,共17年),使得移民安置能够及早进行,可以从容安置移民的生产和生活。
二项式定理形式上的特点(1)二项展开式有n+1项,而不是n项.(2)二项式系数都是C_n^k(k=0,1,2,…,n),它与二项展开式中某一项的系数不一定相等.(3)二项展开式中的二项式系数的和等于2n,即C_n^0+C_n^1+C_n^2+…+C_n^n=2n.(4)在排列方式上,按照字母a的降幂排列,从第一项起,次数由n次逐项减少1次直到0次,同时字母b按升幂排列,次数由0次逐项增加1次直到n次.1.判断(正确的打“√”,错误的打“×”)(1)(a+b)n展开式中共有n项. ( )(2)在公式中,交换a,b的顺序对各项没有影响. ( )(3)Cknan-kbk是(a+b)n展开式中的第k项. ( )(4)(a-b)n与(a+b)n的二项式展开式的二项式系数相同. ( )[解析] (1)× 因为(a+b)n展开式中共有n+1项.(2)× 因为二项式的第k+1项Cknan-kbk和(b+a)n的展开式的第k+1项Cknbn-kak是不同的,其中的a,b是不能随便交换的.(3)× 因为Cknan-kbk是(a+b)n展开式中的第k+1项.(4)√ 因为(a-b)n与(a+b)n的二项式展开式的二项式系数都是Crn.[答案] (1)× (2)× (3)× (4)√

尊敬的老师,亲爱的同学们:今天国旗下讲话的题目是:“说说爱国卫生月”。同学们,四月是个春暖花开的季节,可你还知道四月是个什么月吗?告诉你吧,四月是全国爱国卫生月。因为卫生工作关系到每一个人,所以请大家在日常工作、学习、生活中积极主动做好卫生工作,保持良好的正确的卫生习惯,促进健康成长。1、保持良好的个人卫生习惯,注意饮食卫生,不能在路边小摊随便购买食品,因为路边摊卫生根本就不能得到保证,各种尘埃、苍蝇、不干净的食品用具等都隐藏着多少有害细菌,但是我们有时也发现有的同学在放学后就喜欢在这些路边小摊驻足购买食品,这是非常不卫生的。在个人卫生习惯中,养成饭前便后要洗手,勤剪指甲,勤洗澡,不随便使用别人的生活用品,如毛巾、衣服、拖鞋、餐具等。遵守作息时间,做到起居有规律。2、均衡饮食,随气候变化而增减衣服,定期运动,充足休息。在日常生活中同学们应该按照生活规律,定时用膳,三餐饭做到定量,不能饿一餐,饱一餐,特别是早晨,我们有的同学就往往因为睡懒觉而未吃早餐,这对身体健康和学习精力都是不利的。同学们早晨起床后到户外锻炼,呼吸一些新鲜的空气,伸伸腰,踢踢腿,跑跑步都是很有好处的。
1、说说旅游环境容量测算对颐和园环境保护所起的作用。点拨:旅游环境容量测算对颐和园环境保护所起的作用是通过对游客流量的控制来实现的。颐和园的旅游吸引物有许多是珍贵的文物,游客的触摸、践踏等都会使文物遭受损耗控制客流量就控制了这些损耗。游客过多,废弃物也过多,超过颐和园的承受能力就会造成污染,控制客流量可以使废弃物控制在处理能力范围内。控制游客容量,可避免游客过多造成旅游氛围和景观的破坏,可避免发生各种矛盾和不文明行为乃至犯罪行为。旅游环境容量测算为颐和园的管理、发展和规划提供了基本依据,有助于管理部门因时因地做好管理、监督、疏导工作,有助于制订颐和园旅游发展规划,还有助于采取颐和园客流的时空分流措施。2、你还有没有更好的办法来解决颐和园旅游环境容量问题。点拨:解决颐和园旅游环境容量问题可以从“开源”和“节流”两方面加以考虑。
