$$\begin{array}{l}\begin{array} { l | c | c } \text { Game } 1 & \text { Points } & \text { Rebounds } \\\hline \text { Levy } & 20 & 3 \\\text { Cowens } & 16 & 5 \\\text { Williams } & 8 & 12 \\\text { Miller } & 6 & 11 \\\text { Jenkins } & 10 & 2\end{array}\\\\\begin{array} { l | c | c } \text { Game } 2 & \text { Points } & \text { Rebounds } \\\hline \text { Levy } & 18 & 4 \\\text { Cowens } & 14 & 3 \\\text { Williams } & 12 & 9 \\\text { Miller } & 4 & 10 \\\text { Jenkins } & 10 & 3\end{array}\end{array}$$

A) $\left[ \begin{array} { l l } 5 & 62 \end{array} \right]$
В) $\left[ \begin{array} { r r } 7 & 38 \\ 30 & 8 \\ 21 & 20 \\ 21 & 10 \\ 5 & 20 \end{array} \right]$
C) $\left[ \begin{array} { r r } 38 & 7 \\ 30 & 8 \\ 20 & 21 \\ 10 & 21 \\ 20 & 5 \end{array} \right]$
D) $[ 625 ]$ Answer: C
-The tables below show the times by three runners in two heats of a race. Write a matrix that shows the increase (decrease) in each time from the first heat to the second. $\begin{array}{l|l}\text { Heat 1 } & \begin{array}{l}\text { Time } \\\text { (sec.) }\end{array} \\\hline \text { Russell } & 15.5 \\\text { Sergy } & 15.8 \\\text { Omar } & 162\end{array}$

$\begin{array}{l|l}\text { Heat } 2 & \begin{array}{l}\text { Time } \\(\mathrm{sec}) \end{array} \\\hline \text { Russell } & 15.3 \\\text { Sergy } & 15.4 \\\text { Omar } & 15.7\end{array}$

A) $\left[ \begin{array} { l l } 150 & 15.8 \\ 15 & 16.2 \\ 15.5 & 15.3 \end{array} \right]$
B) $\left[ \begin{array} { l } - 0.2 \\ - 0.4 \\ - 0.3 \end{array} \right]$
C) $\left[ \begin{array} { r } - 0.2 \\ - 0.4 \\ 0.5 \end{array} \right]$
D) $\left[ \begin{array} { l } - 0.2 \\ - 0.4 \\ - 0.5 \end{array} \right]$
