50 g calcium carbonate is heated to form calcium oxide and \( \mathrm{CO}_{2}(\mathrm{~g}) \) Calculate the percentage yield if 21 g facut Calciam axiae. is formed.

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

\( \begin{array}{llcc}3.7 \ldots 2 & 75 \ldots 404 & 4.5 \ldots 1 & 1.75 \ldots \\ \text { C) } & \text { Metti una cifra al posto dei puntini in modo da ottenere un numero divisibile per } 11: \\ 1 \ldots 67 & 13 \ldots 09 & 70.9 \ldots 5 & 5.03 \ldots\end{array} \)

Find all solutions of the equation in the interval \( [0,2 \pi) \). \[ (\csc \theta-\sqrt{2})(\sec \theta+\sqrt{2})=0 \] Write your answer in radians in terms of \( \pi \). If there is more than one solution, separate them with commas. \( \theta=\square \)
