Answer:
b) f(3) is defined, but is not equal to the limit
Step-by-step explanation:
The portion of the function defined by the rational expression is equivalent to x/(x+3), which has a value of 1/2 at x=3. This is the limit of f(x) from the left or right as x approaches 3. However, the function is not defined at that point as 1/2. Rather, it is defined to be f(3)=1.
So, the limits at f(3) exist and are 1/2, but the function is defined as a different value there.
The only applicable statement is the second one.
Answer:
21 minutes
Step-by-step explanation:
Her expected commute time is given by the probability of having to wait for the train (0.2) multiplied by the commute time in this scenario (25 min), added to the probability of not having to wait for the train (1 - 0.2) multiplied by the commute time in this scenario (20 min). The expected commute time is:
Her expected commute time is 21 minutes.
