Simplify the following leaving your answer in positive index<br><br> 1) (x/y)^-4 x (y/x)^8

Basile [38]

Answer:

$(\frac{x}{y})^{-4} * (\frac{y}{x})^8 = (\frac{y}{x})^{12$

Step-by-step explanation:

Given

$(\frac{x}{y})^{-4} * (\frac{y}{x})^8$

Required

Determine the solution to this

$(\frac{x}{y})^{-4} * (\frac{y}{x})^8$

In law of incides:

$\frac{a}{b} = \frac{b}{a}^{-1}$

This implies that:

$(\frac{x}{y})^{-4} * (\frac{y}{x})^8$ is equivalent to:

$(\frac{y}{x})^{-(-4)} * (\frac{y}{x})^8$

$(\frac{y}{x})^{4} * (\frac{y}{x})^8$

Apply first law of indices:

$(\frac{y}{x})^{4+8$

$(\frac{y}{x})^{12$

Hence:

$(\frac{x}{y})^{-4} * (\frac{y}{x})^8 = (\frac{y}{x})^{12$

If the probability of rain is 0.75, the probability of fog is 0.25, and the probability of rain and fog is 0.25, what is the

alexgriva [62]

Answer:

$P(A \cup B) = 0.75$

Step-by-step explanation:

There are two scenarios:

A - Rain

B - Fog.

The probability of rain or fog is determined by the Addition Rule, given that A and B are not mutually excluyent:

$P(A\cup B) = P(A) + P(B) - P(A\cap B)$

$P (A\cup B) = 0.75 + 0.25 - 0.25$

$P(A \cup B) = 0.75$
