Step-by-step explanation:
f(x) = y ( true statement)
y = -1/5x + 3
To find the inverse of any given function we switch the X and Y
X = -1/5y + 3
isolate y so:
x-3 = -1/5y
Multiply both sides by -5
-5(x-3) = y
-5x + 15 = y
(0,infinity) is the answer for that one I think... because y is undefined at x=0 so it’s not included in the interval so it is (0,infinity) with a parenthesis at 0 because it is not included in the interval
Answer:
Not independent
Step-by-step explanation:
This problem involves independence criteria for conditional probabilities.
The two events will be independent if P(A/B)=P(A) or P(B/A)=P(B)
Let us assumes that event A is for student attending private college and B is for student graduating in four years.
So we are given the following probabilities
P(A)=0.20
P(B)=0.55
P(B/A)=0.79
As we can see that P(B/A)≠P(B) so the events A and B are not independent.
So based on the above results we can say that "attending a private college or university" is not independent of "graduating in four years". Thus the two events "attending a private college or university" and "graduating in four years" are dependent.
