Ira Lisetskai [31]

<u>Answer:</u>

The correct answer option is c. $\frac{1}{9a^2}$ .

<u>Step-by-step explanation:</u>

We are given an expression $(27a^{-3})^{-\frac{2}{3} }$ and we are supposed to simplify it.

We can also write $(27a^{-3})^{-\frac{2}{3} }$ as $(\frac{3^3}{a^3} )^{-\frac{2}{3} }$ .

We know the power rule (a^m)^n=a^{mn} which means that to raise a power to a power you need to multiply the exponents.

So multiplying the exponents to get:

$\frac{3^{(3.-\frac{2}{3})} }{a^{(3.\frac{2}{3})} }\\\\\frac{3^{-2}}{a^2}\\ \\\frac{1}{3^2a^2} \\\\\frac{1}{9a^2}$

Therefore, the correct answer option is c. $\frac{1}{9a^2}$ .

Michelle is giving away prizes at one of her meetings.the prizes include 5 stress balls , 3 notepads , 2gift cards and 6 sticky

harina [27]

Answer:

13 out of 16 (13/16)

Step-by-step explanation:

Add all of the items together.

5 stress balls + 3 notepads + 2 gift cards + 6 sticky notes = 16 items

So, now you have to find the probability out of 16.

Since there are 5 stress balls and 2 gift cards, there is a 5 out of 16 chance of passing out stress balls(5/16) and a 2 out 16 chance of handing out gift cards(2/16)

So, she has a 3 out 16 chance of handing out stress balls more than gift cards.

hope this helps and makes sense:)
