(x^4)^-3= x^-12

x^-12= 1/(x^12)

1/(x^12)= (2x^4)/1= (2x^4)/(x^12)

(2x^4)/(x^12)= 2/x^8

Final answer: 2/x^8

Answer: $H_0:\mu=120$

$H_A:\mu\neq120$

Step-by-step explanation:

Let $\mu$ denotes the average braking distance for a population of small car.

Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.

i.e. $\mu=120$

Objective of test : Whether the statement made in the advertisement is false

i.e. $\mu\neq120$

Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.

So the null and the alternative hypotheses for the test will be:

$H_0:\mu=120$

$H_A:\mu\neq120$
