Answer:

a = 5

b =  - 3

Step-by-step explanation:

Let set up the equation

{2}^{ - 3}  \times  {a}^{ - 3}  =   {10}^{b}

First, let solve for a.

Since our product base is 10 and one of our factor base is 2. We need to find a number to multiply 2 by to get 10.

2 \times a = 10

a =  \frac{10}{2}

a = 5

Let replace a in the equation,

{2}^{ - 3}  \times  {5}^{ - 3}  =   {10}^{b}

Using the rule that if two exponet have the same power but different bases, we multiply the bases and keep the same power.

We already multiplied the bases.

The power stay the same so b=-3

A single die is rolled twice. Find the probability of rolling an even number the first time and a number greater than 3 the seco
IceJOKER [234]

Events

• A: an even number is rolled in the first time

,

• B: a number greater than 3 is rolled the second time

The probability of rolling an even number is:

\begin{gathered} P(A)=\frac{\text{ number of favorable outcomes}}{\text{ total possible outcomes}} \\ P(A)=\frac{3}{6} \\ P(A)=\frac{1}{2} \end{gathered}

The probability of rolling a number greater than 3 is:

\begin{gathered} P(B)=\frac{\text{ number of favorable outcomes}}{\text{ total possible outcomes}} \\ P(B)=\frac{3}{6} \\ P(B)=\frac{1}{2} \end{gathered}

Events A and B are independent, then the probability of one happening after the other is:

\begin{gathered} \text{ P(A and B) = }P(A)\cdot P(B) \\ \text{ Substituting with the values previously found:} \\ \text{ P(A and B) = }\frac{1}{2}\cdot\frac{1}{2} \\ \text{ P(A and B) = }\frac{1}{4} \end{gathered}
