Answer:

Step-by-step explanation:

The original price of the sweater that Stuart bought was $30.

The sweater was on sale for 30% off the regular price. This means that the amount of money that was removed from the original price is

30/100 × 30 = 0.3 × 30 = 9

The price at which the sweater was offered for sale would be

30 - 9 = $21

He also had an additional 25% off coupon. The value of the coupon would be

25/100 × 21 = 0.25 × 21 = $5.25

Therefore, the amount that he paid for the sweater would be

21 - 5.25 = $15.75

Considering it's concept, it is found that the number of outcomes in the sample space is of 9.

<h3>What is the sample space of an experiment?</h3>

The sample space is the <u>set that contains all possible outcomes for an experiment</u>.

In this problem, there are 2 trials, each with 3 possible outcomes(red, blue or green), hence the <u>number of possible outcomes</u> is given by:

N = 3² = 9.

TEA [102]
To find the volume of this one we need to break it down 
now i see half of a cylinder and rectangle:)
but first lets find the volume of the rectangle...
In order to find the Volume of a rectangle we need to use this formula...
Length x width x height 
in this case...
length = 10in
width = 6 in 
height = 8in
lets solve:)
10 x 6 x 8 = 480
or we write it like this 
480in³

now time to find the volume of the half cylinder:)
But first lets remember the volume for a cylinder
Volume = \pi r^{2} h
So lets find our measurements 
\pi = 3.14
r² = 5² or 25
h = 6 
so lets plug in our values just like our formula said:)
3.14 x 25 x 6 
now lets easily solve 
<span>3.14 x 25 x 6 = 471
</span>now since we found an entire cylinder and we only want half of a cylinder lets divide our answer in half
471 ÷ 2 = 235.5
so we write it like this 235.5units³
But we have to add both of our multiples together so lets do that
Volume of rectangle = <span>480in³
</span>volume of half sphere = 235.5units³
480 + 235.5 = 715.5
answer = 715.5units³
I hope this helped and everyone learned something new
anyways don't forget to
