mohon bantuan teman*

1. • Rata2= (6x6)+(7x8)+(8x10)+(9x9)+(10x7)/6+8+10+9+7= 36+56+80+81+70/40= 323/40= 8,075
• Yg mengikuti remedial= 8+6= 14

2. 40, 40, 40, 40, 40, 43, 43, 43, 43, 43,
43, 43, 46, 46, 46, 46, 46, 46, 46, 46,
46, 46, 46, 46, 46, 46, 49, 49, 49, 49,
49, 52, 52, 52, 52, 52, 52, 54, 54, 54
(i) Median= 46+46/2= 92/2= 46
(ii) Modus= 46
(iii) Mean= (40x5)+(43x7)+(46x14)+(49x5)+(52x6)+(54x3)/5+7+14+5+6+3
= 200+301+644+245+312+162/40= 1864/40= 46,6
Pernyataan yg benar= (ii) dan (iii)
