请教一道判断题圆的周长扩大2倍,半径也扩大2倍请充分说明理由
这是正确的,因为周长公式周长=2*圆周率*半径圆周率是个定植,所以圆的周长扩大2倍,半径也扩大2倍
c=2Pi*Rc'=2Pi*R'c'=3c所以R'=3R所以是正确的
是对的,理由如下:(派取3.14)若圆的半径X,则圆的周长为6.28X圆的半径扩大两倍,为2X,则圆的周长为12.56X因为12.56/6.28=2所以圆的周长也扩大了两倍.美女们,帅哥们。。我有一道数学判断题 ,,,请请请教啊啊啊!求求了!!!!_百度知道

请教一概率题
首先要知道,每道题被每个人抽到的概率是和抽签顺序无关的。在这个基础上得到的结论是,每道题被某人抽到的概率都是1/10。由于总共有4道判断题,因此任何人抽到判断题的概率都是4/10。
如果你不相信“每道题被每个人抽到的概率是和抽签顺序无关的”这个命题的真实性,也可以分四种情况讨论:
甲选择,乙选择,丙判断:6/10 * 5/9 * 4/8。(即:甲在10道题中抽到选择题的概率,乘以乙在剩下的9道题中抽到选择题的概率,乘以丙在剩下的8道题中抽到判断题的概率。以下不赘)
甲选择,乙判断,丙判断:6/10 * 4/9 * 3/8。
甲判断,乙选择,丙判断:4/10 * 6/9 * 3/8。
甲判断,乙判断,丙判断:4/10 * 3/9 * 2/8。
总概率是以上四种情况相加,得288/720,等于4/10。

大哥大姐们,请教点英语方面的问题,兄弟愚钝啊~一些判断题和填空题,填空题:1、( )is the scientific study of language;( ) relates the study of language to society.2、There are a number of relatively independent branches within the area of linguistics:( ) and ( ) studying the speech sounds;( ) studying the formation of words,( ) and ( ) studying meaning.3、When a ( ) has become the primare language of a speech community,and is required by the children of that speech community as their native language,it is said to have become a ( ).4、A ( ) is a word formed by combining parts of other words,for example,smog.5、The most basic element of meaning is called( ).6、According to the Apeech Act Theory,a speaker minghtbe performing three acts simultaneously when speaking,namely:( )act,( )act and ( )act.判断题1、Speech is a complex human phenomenon which involves mental and physical components and both phonetics and phonology aim at accounting for this complexity.( )2 In the twentieth century variations in speech became more and more a sign of social class and the idea of "the Queen's Engish" was born.3 The symbols used by the International Phonetic Alphabet are mainly taken from Roman alphabet.4 Speech involves four processes:initiation,phonation,oro-nasal process and articulation.5 The rhythm in language is characterized by the timing pattern of successive syllables.6The first part of a diphthong is much longer and stronger than the second part.7 Nasals,laterals and ApproximantStops,Fricatives and Affricates are always voiceless.8 An affricate is a type of consonant that is produced with the blade of the tongue raised against the region just behind the alveolar ridge.9 Semi-vowels are phonetically vowels but phonologically consonants.10 Progressive assimilation is also called perserverative or left-to-right assimilation.11 Assimilation results in a sound that is more co-articulation results in an allophone of the same phoneme.12 Elision refers to the disapperance of one or more sounds in connected speech which would be present in a word prnounced in isolation.13 Elision is an optional process.14 Any syllable with a schwa in it will never be the stressed syllable.15 We usually assign primary stress on the left in noun phrase adn on the right in compounds.
这是关于语言学的啊.去翻书吧!记不到那么多.第一题第一个空是linguistics
希腊士兵厌倦了战斗,内部开始争吵。a.错。因为主语宾语相同时要用反身代词。b. 为互相的意思(两两之间)。即使是c.也是表示(在多人中)两两之间。意义不对。而且,要说quarrel with each other.故答案是D
