Answer:
Step-by-step explanation:
Given is a function
This function is a parabola with vertex at (2,0) and axis of symmetry is x=2
Hence for x<2 the curve would be reflection of x>2
To get inverse we must get one to one funciton only.
So restrict the domain of f(x) to 
Then we have f(x) as one to one with domain x≥2 and range is R+
For this inverse domain is R+ and range is
Step-by-step explanation:
The probability that the dealer will be fined is 0.0948
To find p(a <= Z <= b) = F(b) - F(a)
P(X < 20) = (20 - 30.5)/3.4489
= -10.5/3.4489
= -3.0444
= P(Z < -3.0444) from standard normal table
= 0.00117
P(X < 26) = (26 - 30.5)/3.4489
= -4.5/3.4489 = -1.3048
= P(Z < -1.3048) From standard normal table
= 0.09599
P(20 < x < 26) = 0.09599 - 0.00117 = 0.0948
The answer in this question is 0.0948
Diagram C shows the inverse of P(x).
What do u mean like a fraction?
