Answer:   Answer choice:  [A]:  " x⁻ ⁴ " .

_____________________________________________

Step-by-step explanation:

_____________________________________________

Given:

{x ^ ^( {\frac{-4}{7}) }^7 ;

 →  Simplify.

_____________________________________________

Note the following property of exponents:

_____________________________________________

 →   (xᵃ) ᵇ  =  x ⁽ ᵃ * ᵇ ⁾   ;    {a ≠ 0 ;  b ≠ 0 .} .

_____________________________________________

As such:

_____________________________________________

→    {x ^ ^( {\frac{-4}{7}) }^7  ;  

       =  x ^ ([(\frac{-4}{7}) * 7 ]  ;

_____________________________________________

Find:  [(\frac{-4}{7}) * 7 ] ;  Note:  " 7  = [tex]\frac{7}{1} " .

So:  Find:  " [(\frac{-4}{7} * [tex]\frac{7}{1} " ;

The 2 (two) "7 's " ;  cancel out to "1" ;  

      →   {since:  " 7 ÷ 7 = 1 " } ;

And we have:

  -4 * 1 = -4 .

So, we have:

       " x ⁻ ⁴ "  ; which is:  Answer choice:  [A]:  " x⁻ ⁴  " .

___________________________________________

Choice:  [C} —  is also an equivalent;  however, the question asks for the "simplest form" — which is:  Answer choice:  [A].

Alexxandr [17]

Answer:

The right answer is:

a.H0: μd = 0; H1: μd > 0

Step-by-step explanation:

The claim that want to be tested is that the sales were significantly increased after the commercial, indicanting that the advertisement campaign was effective.

This claim is usually expressed in the alternative hypothesis as it has to have enough evidence to prove that it is true.

Then, the alternative hypothesis H1 should state that the difference (sales after - sales before) is higher than 0.

The null hypothesis would state that the difference is not significantly different from 0, or, in other words, that the sales are the same before and after and that the variation is due to pure chance.

Then, the null hypothesis H0 would state that the difference is equal to 0.

The right answer is:

a.H0: μd = 0; H1: μd > 0
