08 CE MATHS 答案 20分 更新: MC同埋LQ 更新 2: 都唔知你地D MC 啱唔啱GE, LQ重要d,一定要LQ
尼到唔可以SHOW埋問題... 想再睇埋問題可以到以下網址睇下=]http://lsforum.net/board/viewthread.php?tid=61803 math paper1 answers (from uwants) 題號可能有誤 紅粗字為分數 1. 3 ab^3 2. 3 a) t=5s/2 b) s=274, t=685 3. 3 a) x>=35/4 b) x=9 4. 3 a) m=1,3 b) k=2,3 5. 3 S40.0W 6. 3 1/3 7. 8? a) B(-3,4) C(4,-3) b) Slope of OB=-4/3, slope of OC= -3/4, so not colinear c) Equation of CD: x-y-7=0 , D(10,3) 8. 5 x = 33 degrees y = 76 degrees z = 28 degrees 9. 4 a) 97 b) Yes. 100>97 10. 5 a) 450 bi) 80% bii) 80 11. 9 a) radius = 12 cm, height = 16 cm b) 768 pi c) not similar QUOTE: radius of X=12 slant height of X=20 radius of Y=3 slant height of Y=10 12/20 =/= 3/10 NOT simlilar 12. 8 a) b=2 b) k>-16 c) y=-16 ( CAN BE OTHER ANS ) 13. 8? 50條bb 頻數 a 12 b 10 c 累積頻數 l 16 k 47 m 呢條應該差d野 Ans: a) a=4, b=21, c=3 b) mean=3.28kg, standard deviation=0.299kg 14. 概率 統計 11 ai) 3/5 aii (1) 4/21 aii (2) 419/630 bi) $2100, $5000 bii) Add $1000 to each sales 15. 3D Figures 11 http://www.uwants.com/attachments/day_080505/20080505_76b1c16877a705ca2a02n8hgID0R6y6p.gif a) Find BH ? b) Find Angle CBH ? ci) Find the angle between CBH and ABC ? cii) If a girl stands at a point K on BC, is it possible that the angle of elevation of H from K is 75 degrees?
