yakni
(4,3 ; 4)
Pembahasan:
Dari gambar soal:
Didapat data-data
I₁ = 6; x₁ = 3; y₁ = 3
I₂ = 4; x₂ = 2; y₂ = 5
I₃ = 6; x₃ = 6; y₃ = 3
I₄ = 4; x₄ = 6; y₄ = 6
x₀ = I₁x₁ + I₂x₂ + I₃x₃ + I₄x₄
I₁ + I₂ + I₃ + I₄
= 6.3 + 4.2 + 6.6 + 4.6
6 + 4 + 6 + 4
= 86

= 4,3
y₀ = I₁y₁ + I₂y₂ + I₃y₃ + I₄y₄
I₁ + I₂ + I₃ + I₄
= 6.3 + 4.5 + 6.3 + 4.6
6 + 4 + 6 + 4
= 80

= 4
