Answer:
C. Time since the person starts walking is the input.
D. t represents the input.
Step-by-step explanation:
The distance a person walks, d, in kilometers, is a function of time, t, in minutes, since the walk begins.
So, we can write d = f(t)
If the person is moving with constant speed, then the above function will be linear.
Now the true statements are
C. Time since the person starts walking is the input.
D. t represents the input.
All the other statements are false. (Answer)
Answer:
find the difference of points on the graph
Step-by-step explanation:
The cumulative frequency graph (CDF) represents the integral of the probability distribution function (PDF). You find the probability that X is in some interval by subtracting the value of the CDF at the low end of the interval from the CDF value at the high end of the interval.
p(a < x < b) = cdf(b) -cdf(a)
Let me break this up.
Note: (f o g)(2) = f(g(2)).
Note: g(2) = (2, 2) means when x is 2 y is 2.
In other words, g(2) is 2.
We know that f(g(2)) = f(2).
You can see that f(2) = -3. This is given in the point (2, -3).
So, f(g(2)) = -3.
Done.
