. What is the probability of rolling 15 with a pair of dice?

Wewaii [24]

Answer:

If we consider three 20 sided dice, the chance of rolling 15 on each of them is: P = (1/20)³ = 0.000125 (or P = 1.25·10⁻⁴ in scientific notation).

Write the augmented matrix for each system of equations.

Fudgin [204]

We are given the equations: 

10x = 10

-5x - 8y = 9

Since we don't have a coefficient of y in the first equation, we will rewrite the first equation as:

10x + 0y = 10

Writing an Augmented matrix for the 2 equations:

10x + 0y = 10

-5x - 8y = 9

$\left[\begin{array}{ccc}10&0|&10\\-5&-8|&9\end{array}\right]$
