16. Tenis meja = 6
sepak bola = 11
bulutangkis = 9
catur = 8
kasti = 4
Jumlah siswa seluruhnya = 6 + 11 + 9 + 8 + 4 = 38 orang
17. Kopra = 55°
cokelat = 130°
cengkih = 90°
kopi = 360 - 55 - 130 - 90 = 85°
Hasil kopi = 1.700 Kg
Hasil cokelat = 130/85 x 1.700 = 2.600 Kg
18. Nilai ulangan Nia = 70, 85, 90, 100, 75, 90, 80, 95
Nilai rata-rata = jumlah nilai : 8
= (70 + 85 + 90 + 100 + 75 + 90 + 80 + 95)/8
= 685 / 8
= 85,625
19. Nilai ulangan Nia sbb :
Nilai 6 7 8 9 10
Frekuensi 3 1 3 2 1
Total nilai = (6x3) + (7x1) + (8x3) +(9x2) + (10x1)
= 18 + 7 + 24 + 18 + 10
= 77
Total frekuensi = 3+1+3+2+1 = 10
Nilai rata-rata = Total nilai : total frekuensi
= 77/10 = 7,7
