Answer:
none of them its <
Step-by-step explanation:
The root of every order of 1 is still 1, in other words, we have
![\sqrt[n]{1}=1](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B1%7D%3D1)
So, if we evaluate the function at 1, we have
![\dfrac{\sqrt{1}-1}{\sqrt[3]{1}}-1 = \dfrac{0}{1}-1 = 0-1 = -1](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csqrt%7B1%7D-1%7D%7B%5Csqrt%5B3%5D%7B1%7D%7D-1%20%3D%20%5Cdfrac%7B0%7D%7B1%7D-1%20%3D%200-1%20%3D%20-1)
Answer: $375
Step-by-step explanation:
Given : The probability of winning $100 : P(100)= 0.25
The probability of winning $200 : P(200)= 0.50
The probability of winning $1000 : P(1000)= 0.25
Now, the the expected value of that lottery ticket is given by :-
![P(100)\times 100+P(200)\times200+P(1000)\times1000\\\\=0.25\times100+0.50\times200+0.25\times1000\\\\=375](https://tex.z-dn.net/?f=P%28100%29%5Ctimes%20100%2BP%28200%29%5Ctimes200%2BP%281000%29%5Ctimes1000%5C%5C%5C%5C%3D0.25%5Ctimes100%2B0.50%5Ctimes200%2B0.25%5Ctimes1000%5C%5C%5C%5C%3D375)
Hence, the the expected value of that lottery ticket =$375
