Question

Kakak tolong no36,37,38,39,40 pake cara kakak

Answer 1

No 37 = 3 : 4 : 5
= 3 + 4 + 5 = 12 (sbg penyebut)

= 5/12 x 720.000
= 3.600.000/12 = 300.000

No 38 : mean = jumlah data/bnyknya data
8,75 = 60+x / 8
60+x = 70
x = 70 - 60 = 10

No 39 = titik P (-3,2)
Q (-1,5)
R (4,5)
S (2,2)

No 40 nanti kamu gambar aja
