Answer:
It depends on how you define an outcome.
Usually, the outcomes are considered to be the number showing on the top face of the die (number cube) when it comes to rest on a horizontal surface. If that is how you define outcomes, then the sample space is the set of numbers 1–6: {1, 2, 3, 4, 5, 6}.
Step-by-step explanation:
"This experiment" covers a lot of territory. The student could be checking to see if the die stays on the table or falls to the floor. The student could be experimenting to see if the die changes color or makes a certain kind of noise. The experiment could involve the number of times the die rolls over to a new face before it comes to rest. Until the experiment is properly defined, the sample space is unknown.
If the experiment is to see what number shows on the top face of the die at rest on a horizontal surface, then the sample space is presumably the set of numbers 1 through 6.
x^2 - x/5 + 2 = 0
Subtract 2 from both sides.
x^2 - x/5 = -2
Multiply all terms by 5.
5x^2 - x = -10
Add 10 to both sides.
5x^2 - x + 10 = 0
We can now apply the quadratic formula:
1 ± (√ 1 - 200) / 10
1 ± √-199 / 10
1 ± i√199 / 10
<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>
Let: x = number of copies sold
We can formulate the following equation to solve for x:
1.50x - 0.9x - 600 = 0
x = 1000
Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.
Answer:
Total pay = 400+ 1650* 5/100= 482,5 $

Hi :)
Let's remember some arithmetic w/ negative integers :
a+(-b)=a-b
a-(-b)=a-b
Now
8-(-9)=8+9=17
So the answer's 17
I hope this helps
