If the area of inequality (area between the line of perfect equality and the Lorenz Curve) equals 0 and the area beneath the line of perfect equality (given by OAB in the diagram) equals 0.7 , calcus the Gini coefficient. A 0,5 B 0,35 C 0,6 D 0,7

Un quadrato ha l'area di \( 169 \mathrm{~m}^{2} \). Aumentan- done l'area di \( 27 \mathrm{~m}^{2} \), quale variazione subisce il perimetro?

Subtract. \[ \frac{9}{2 x^{2}-15 x+27}-\frac{3}{2 x^{2}-17 x+36} \] Simplify your answer as much as possible.
