Determine whether the underlined numerical value is a parameter or a statistic. Explain your reasoning. The average annual salary of 50 of a company's 800 employees is \( \$ 54,000 \). Choose the correct answer below. A. Statistic, because the data set of salaries of 50 employees is a sample. B. Statistic, because the data set of all employees' salaries is a population. C. Parameter, because the data set of salaries of 50 employees is a sample. D. Parameter, because the data set of all employees' salaries is a population. E. Statistic, because the data set of all employees' salaries is a sample. F. Statistic, because the data set of salaries of 50 employees is a population. G. Parameter, because the data set of all employees' salaries is a sample. H. Parameter, because the data set of salaries of 50 employees is a population.

To check the solution, substitute 0 for \( x \) in the original equation and simplify. \[ \begin{array}{l} \frac{11(0)+3}{5(0)+6} \stackrel{?}{=} \frac{1}{2} \\ \frac{0+3}{0+6} \stackrel{?}{=} \frac{1}{2} \\ ? \vee \frac{1}{2}\end{array} \]

Sulfuryl chloride can dissociate into sulfur dioxide and chlorine: \[ \mathrm{SO}_{2} \mathrm{Cl}_{2}(\mathrm{~g}) \rightleftharpoons \mathrm{SO}_{2}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \] At \( 100^{\circ} \mathrm{C} \), the equilibrium constant in terms of pressures, \( \mathrm{K}_{\mathrm{p}} \), for this dissociation reaction is 2.40 . (a) If 12.76 g of sulfuryl chloride is placed in a 12.67 - L vessel and heated to \( 100^{\circ} \mathrm{C} \), what is the partial pressure of sulfur dioxide when equilibrium is attained? (b) What fraction of sulfuryl chloride is dissociated at equilibrium?

Esercizio 3 Un trapezio rettangolo ha l'area espressa dal polinomio \( 3 x^{2}+5 x-2 \). La base maggiore misura \( 2 x-2 \) e quella minore \( x+1 \). Calcola l'altezza del trapezio. Esercizio 4 Senza fare la divisione, trova quali dei seguenti binomi \( x+\frac{1}{-}: x-1 ; x+2 ; x-2 \)

Sulfuryl chloride can dissociate into sulfur dioxide and chlorine: At \( 100^{\circ} \mathrm{C} \), the equilibrium constant in terms of pressures, Kp , for this dissociation reaction is 2.40 . (a) If 18.05 g of sulfuryl chloride is placed in a 19.01-L vessel and heated to \( 100^{\circ} \mathrm{C} \), what is the partial pressure of sulfur dioxide when equilibrium is attained? (b) What fraction of sulfuryl chloride is dissociated at equilibrium?

Quostlon 6 A box contains 6 balls of the same size of which 2 are red, 3 are yellow and 1 is white. If 2 balls are selected at random from the box without replacement, what is the probability that the first ball will be red and second one yellow?
