Lets simplify each one of the rational expressions using the product rule of exponents: a^n*a^m=a^{n+m} and the quotient rule of exponents: \frac{a^n}{a^m} =a^{n-m}.

1.  \frac{-3x^2}{2y^2} * \frac{y^2}{9x} =- \frac{x}{6} = \frac{-1}{6} x

2. \frac{5y^2}{10x^2} * \frac{4x^2}{y} =2y

3. \frac{-9y^2}{5x} * \frac{-10x^2}{3y} =6xy

4. \frac{14x^2}{5y} * \frac{-10y}{7x} =-4x

We can conclude that you should pair the rational expressions with their simplest form as follows:
6xy-----\ \textgreater \ \frac{-9y^2}{5x} * \frac{-10x^2}{3y}
\frac{-1}{6} x-----\ \textgreater \  \frac{-3x^2}{2y^2} * \frac{y^2}{9x}
-4x-----\ \textgreater \ \frac{14x^2}{5y} * \frac{-10y}{7x}
2y-----\ \textgreater \ \frac{5y^2}{10x^2} * \frac{4x^2}{y}

dezoksy [38]

Answer: D

<u>Step-by-step explanation:</u>

In order to increase each ticket by $2, you are ADDING 2 to each value.

So you create a matrix of all 2's and add that to the given matrix.

\left[\begin{array}{cc}2&2\\2&2\\2&2\end{array}\right] +\left[\begin{array}{cc}8&10\\12&16\\6&8\end{array}\right]\quad =\quad \large \left[\begin{array}{cc}10&12\\14&18\\8&10\end{array}\right]

Conditional Probability Assistance?
krek1111 [17]

Let the event A=\{ Sophomore \}, B=\{ Boy \}

The the probability of the events

P(A \cap B)=\frac{5}{12+18} =\frac{1}{6}

P( B)=\frac{12}{12+18} =\frac{2}{5}

The conditional probability

P(Sophomore|Boy)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/6}{2/5} =\frac{5}{12}
