I think its C but im not 100% sure.
Answer:
<em>Expected Payoff ⇒ $ 1.50 ; Type in 1.50</em>
Step-by-step explanation:
Considering that 1 out of the 100 tickets will have a probability of winning a 150 dollar prize, take a proportionality into account;
![100 - Number of Tickets,\\1 - Number of Tickets You Can Enter,\\\\1 / 100 - Probability of Winning,\\$ 150 - Money Won,\\\\Proportionality - 1 / 100 = x / 150, where x - " Expected Payoff "\\\\1 / 100 = x / 150,\\100 * x = 150,\\\\Conclusion ; x = 1.5 dollars](https://tex.z-dn.net/?f=100%20-%20Number%20of%20Tickets%2C%5C%5C1%20-%20Number%20of%20Tickets%20You%20Can%20Enter%2C%5C%5C%5C%5C1%20%2F%20100%20-%20Probability%20of%20Winning%2C%5C%5C%24%20150%20-%20Money%20Won%2C%5C%5C%5C%5CProportionality%20-%201%20%2F%20100%20%3D%20x%20%2F%20150%2C%20where%20x%20-%20%22%20Expected%20Payoff%20%22%5C%5C%5C%5C1%20%2F%20100%20%3D%20x%20%2F%20150%2C%5C%5C100%20%2A%20x%20%3D%20150%2C%5C%5C%5C%5CConclusion%20%3B%20x%20%3D%201.5%20dollars)
<em>Thus, Solution ; Expected Payoff ⇒ $ 1.50</em>
We can solve this by distributing
![4(8x+5)](https://tex.z-dn.net/?f=4%288x%2B5%29)
Now, distribute the 4 to both 8x and 5.
![32x+20](https://tex.z-dn.net/?f=32x%2B20)
That's your answer!
To solve this question, we need to write this equation in simplified form.
So, Taking the GCF from 2x³ + 4x² - x,
x is divisible by all of them so our new equation will be,
x ( 2x² + 4x - 1)
Correct option is D.
Hope this helped you.. :)
The answer is 7, inversely proportional to x+9 therefore making it 22cm squared
hope this helps
