Jawaban:
t Badan indra = 160 cm
Penjelasan dengan langkah-langkah:
Total tinggi badan 15 anak
= 15 x 152 = 2.280 cm Total tinggi badan 16 anak
= 16 x 152,2 =2.440 cm
Tinggi badan Budi 2.440-2.280 = 160 cm
Jawab:
160 cm
Rata-rata 1 = 152
tinggi badan total 1 = 152 × 15 = 2280
Rata-rata 2 = 152,5
Tinggi badan total 2 = 152,5 × 16 = 2440
Tinggi indra = Tinggi badan total 2 - tinggi badan total 1
= 2440 - 2280
= 160 cm
Moga2 membantu :)
