jawab :
172 × ( 6 + 2 ) - ( 171 × 6 ) ÷ ( 8 - 6 )
= ( 172 × 8 ) - ( 171 × 6 ) ÷ ( 8 - 6 )
= ( 1.376 - 1.026 ) ÷ 2
= 350 ÷ 2
= 175 cm
ms = (6ma + 2mb)/(6 + 2)
172 = 6(171) + 2mb/8
172 × 8 = 1.026 + 2mb
1.376 = 1.026 + 2mb
2mb = 1.376 - 1.026
2mb = 352
mb = 350/2
mb = 175 cm
Jadi, tinggi rata-rata 2 orang pemain cadangan adalah 175 cm.
