1.) for the odds would be 2/3 against would be 1/3
2.) i think it would be 157.08 (157 if rounded)
3.) he could make 18 arrangements
Answer:
180
Step-by-step explanation:
we are given
![f(x)=\sqrt[3]{x+2}](https://tex.z-dn.net/?f=%20f%28x%29%3D%5Csqrt%5B3%5D%7Bx%2B2%7D%20%20)
Firstly , we set f(x)=y
![y=\sqrt[3]{x+2}](https://tex.z-dn.net/?f=%20y%3D%5Csqrt%5B3%5D%7Bx%2B2%7D%20%20)
now, we can switch x and y
![x=\sqrt[3]{y+2}](https://tex.z-dn.net/?f=%20x%3D%5Csqrt%5B3%5D%7By%2B2%7D%20%20)
now, we can solve for y
![x^3=(\sqrt[3]{y+2})^3](https://tex.z-dn.net/?f=%20x%5E3%3D%28%5Csqrt%5B3%5D%7By%2B2%7D%29%5E3%20%20)


so, our inverse function is
