flips a fair coin until a tail first appears, and if the number of tosses equals m, then Tom gets a payoff for 2 m pounds. Calcu
ohaa [14]

Answer: the expected value of Tom's payoff is m²

Step-by-step explanation:

Given the data in the question,

E[x] = mp                                        

where p = 1/2

Now Tom gets payoff pounds until a tail first appears = 2m pounds

so

E[x] = m × 1/2 × 2m

E[x] = m²

Therefore the expected value of Tom's payoff is m²

What is the value of x if f(x)=23. f(x)=x^2-7
Setler79 [48]

value of x is: x=\pm\sqrt{30}

Step-by-step explanation:

We are given f(x)=23 and f(x)=x^2-7. We need to find the value of x.

So, f(x)=x^2-7\\ 23=x^2-7\\x^2=23+7\\x^2=30\\Taking\,\, square\,\, root\,\, on\,\, both\,\, sides\,\,\\x=\pm\sqrt{30}

So, value of x is: x=\pm\sqrt{30}
