請問這題該怎麼算呢？😓😓😓

17.來一中嗑泡麵公司預計推出新產品,先以不同價格調查銷售量,以價格為X值(單位:元), 16 Y 4 2/= 64 銷售量為Y值(單位:千箱),調查結果如附表,則下列哪些選項正確? M₂ = 14 (E 試售價 X 20 銷售量 Y| 12 22 13 24 26 28 11 9 10 My Tibo 20 (A)X的標準差小於Y 的標準差 (B)X與Y的相關係數為0.8 (C)設 U=-2X-1,V=Y+1,則 U 與 V 的相關係數為0.8 (D) Y對X的最適直線方程式為y=20.6+0.4x (E)若售價定為 25 元,可預測銷售量為 10600 箱。 U-40-1 V=13 ba = 16+4+0+ baby=144+0+ 0+16+04

我看坊間對於106學測那題的詳解普遍是：「因為目前地球繞日軌跡近似正圓，因此當繞日軌跡變成正圓時，氣溫改變並不明顯。」 但既然都說了目前繞日軌跡是近似正圓，為何103學測那題近、遠日點對於氣溫的影響仍是明顯的，照理來說應該因爲與太陽距離相近... 繼續閱讀

E10. 如圖所示,目前地球自轉軸指向為圖中x,與繞日公轉軸交角約為23.5 度。如果 地球自轉軸的指向偏轉為圖中y,但交角仍為 23.5 度。僅就天文的角度來看,則 地球北半球的夏天與冬天,與實況(現況)相比為何? 103 學測 Do 選項 夏天 (A) 與現況差不多 (B) 比現況冷 (C) 比現況冷 比現況熱 比現況熱 (E) 冬天 與現況差不多 比現況熱 比現況冷 比現況熱 比現況冷 地球 23.5° 23.5° 公轉軌道
