Answer:

C'(4, 0)

Step-by-step explanation:

Translated 6 units to the right means that the x-value increases by 6.

1 unit up means y-value increases by 1.

(-5 + 6, -1 + 1)

(-2 + 6, -1 + 1)

The second point must be C, as the translation lines it up with one of the answers.

Answer:

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Step-by-step explanation:

$\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}$

$X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}$

$X = \begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

If Mike does his mathematics homework today, the probability that he will do it tomorrow is 0.8. The probability that he will do

harina [27]

Answer:

d. 14:11

Step-by-step explanation:

There is a 7 in 10 chance that Mike does his homework today and a 8 in 10 chance he will do it tomorrow, the probability that he will do it both today and tomorrow is:

$P = \frac{7}{10}* \frac{8}{10}\\P=\frac{56}{100}=0.56$

The odds are the probability that an event occurs over the probability that it does not occur:

$Odds = \frac{0.56}{1-0.56}=\frac{56}{44}=\frac{14}{11}$

The odds that he will do it both today and tomorrow are 14:11.
