Kk tolong di bantu 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
