Bismillaah Ijin jawab yaa.. Pertama : Junlah rata-rata tinggi 10 pemain Jumlah tinggi 10 pemain = Tinggi rata-rata × 10 pemain = 162 × 10 = 1620 cm Kedua : Menentukan rata-rata tinggi 5 pemain Misalkan rata-rata 5 pemain itu adalah (x). Jika dalam soal tinggri rata-rata gabungan adalah 160 cm, maka : T. 10 pemain + T. 5 pemain = (10+5) × 160 cm 1620 cm + 5x = 15 × 160 cm 1620 cm + 5x = 2400 cm 5x = 2400 cm - 1620 cm 5x = 780 x = 780/5 x = 156 cm Jadi, tinggi rata-rata 5 pemain tersebut adalah 156 cm

Menentukan Jumlah Tinggi 10 Pemain
Jumlah Tinggi 10 pemain = Tinggi rata-rata x 10 pemain
                                                     = 162 x 10
                                                     = 1620 cm
Menentukan tinggi rata - rata dari 5 pemain
T.10 Pemain + T. 5 pemain = (10 + 5) x 160 cm
      1620 cm +         5a              = 15 x 160 cm
      1620 cm +         5a              = 2400 cm
                                    5a              = 2400 cm - 1620 cm
                                    5a              = 780
                                       a              = 780 : 5
                                       a              = 156 cm
Jadi tinggi rata -rata dari 5 pemain tersebut adalah 156 cm
