Divide each side by n . . . 0 = 1 + 8 . . . Combine like terms on the right side: . . . 0 = 9 . . . No value of 'n' can make this statement true, so there is no solution.

(b) Give an example of nonzero 2×2 matrices A, B, C such that AB=AC, but B C.

DochEvi [55]

Answer:

Example of matrices such hat $AB = AC, B\neq C$

Step-by-step explanation:

We have two give example of 2×2 matrices such that AB = AC BUT B ≠ C.

Example:

$A =\left[\begin{array}{ccc}1&0\\0&0\end{array}\right]\\\\B = \left[\begin{array}{ccc}1&1\\1&2\end{array}\right], C = \left[\begin{array}{ccc}1&1\\1&3\end{array}\right]$

Solving:

$AB = \left[\begin{array}{ccc}1+0&1+0\\0+0&0+0\end{array}\right] = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]$

$AC = \left[\begin{array}{ccc}1+0&1+0\\0+0&0+0\end{array}\right] = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]$

Hence, $AB = AC, B\neq C$

There are two decks of cards. Each deck has a red, a yellow, a blue, and a green card in it. If a card is drawn, from the firs

marta [7]

Probability of choosing Red first is 1/4
Probability of choosing Green second is 1/4 (this coming from the second deck)
The probability of choosing in this order is 1/4 * 1/4 = 1/16

Probability of choosing Green first is 1/4
Probability of choosing Red second is 1/4
The probability of choosing in this order is 1/4*1/4 = 1/16

The total probability of success is 1/16 + 1/16 = 2/16 = 1/8
