Recall that a deck of cards contains 52 cards. These cards consist of four suits (hearts, spades, clubs, and diamonds) of each of the following: \(2,3,4,5,6,7,8,9,10,\) jack, queen, king, and ace. If a card is chosen from a deck of cards, find the probability of each event. A card in black ink

Give the result as a fraction in simplest form. $$ 0.75+\frac{3}{10} $$

True or false? The smaller a sector in a circle graph, the smaller the percent of the total it represents. Explain why.

Give the result as a fraction in simplest form. $$ \frac{2}{11}-\frac{x}{11} $$

Two dice are tossed. Find the probability of each sum of the dice. (Hint: Draw a tree diagram of the possibilities of two tosses of a die, and then find the sum of the numbers on each branch.) A sum of 6

Fill in the table and use it to graph \(y=|x|\) on the coordinate system. $$ \begin{array}{|c|c|} \hline \boldsymbol{x} & \boldsymbol{y} \\ \hline-3 & \\ \hline-2 & \\ \hline-1 & \\ \hline 0 & \\ \hline 1 & \\ \hline 2 & \\ \hline 3 & \\ \hline \end{array} $$

Recall that the axes divide the plane into four quadrants as shown. For Exercises 45 through \(52,\) if a and \(b\) are both positive numbers, determine whether each statement is true or false. $$ (a,-b) \text { lies in quadrant IV. } $$
