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:
Find the slope first by using the equation then you can go from there and either use the equation form and substitute all the numbers to solve for the y-intercept or use the graph.

Answer:
The probability that a worker was taught by method A given that he learned the skill successfully is 0.72.
Step-by-step explanation:
(1)
The information provided is:
<em>A</em> = if method A is used
<em>B</em> = if method B is used
<em>S</em> = successfully learning the skill
P (A) = 0.75
P (B) = 0.25
P (S|A) = 0.80
P (S|B) = 0.95
Compute the probability that a worker was taught by method A given that he learned the skill successfully as follows:
Thus, the probability that a worker was taught by method A given that he learned the skill successfully is 0.72.
(2)
The probability is attached below.
