makasih
1). b. Sabtu (30 kg)
c. Yang banyak - Yang sedikit
= Rabu - Jumat
= 42 - 40 = 2 kg
d. Data diurutkan:
30, 35, 38, 40, 40, 42
Median = (38 + 40)/2 = 78/2 = 39
e. 30 = ada 1
35 = ada 1
38 = ada 1
40 = ada 2
42 = ada 1
Modus = 40
f. jumlah seluruh berat beras/banyak hari
= (40+35+42+38+40+30)/6
= 225/6 = 37,5 kg
2). a. 10
b. 4
c. Data dijabarkan:
4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 10
Median = 7
d. Modus = 8 (paling banyak)
e. Jumlah nilai/banyak nilai
= ((4×3)+(5×4)+(6×5)+(7×4)+(8×7)+(9×2)+(10×5))/(3+4+5+4+7+2+5)
= (12+20+30+28+56+18+50)/30
= 214/30 = 7,1333...
3). a. °Kopi = 360 - (°kelapa + °jagung + °padi)
= 360 - (60 + 90 + 180)
= 360 - 330 = 30°
Kopi = °Kopi/360 × jumlah seluruhnya
= 30/360 × 36 ton
= 1/12 × 36 ton
= 3 ton
b. Padi - Kelapa
= (°Padi/360 × 36) - (°Kelapa/360 × 36)
= (180/360 × 36) - (60/360 × 36)
= (½ × 36) - (⅙ × 36)
= 18 - 6 = 12 ton
c. Modus = Padi karena paling banyak
d. Hasil seluruhnya/banyak data
= 36/4 ← (dari kopi, kelapa, jagung, padi, ada 4)
= 9 ton
