Which function below has the smallest slope? f(x) f(x) = 2x − 3 g(x) graph going through (0, negative 5) and (4, 3) h(x) x h(x)
1 answer:
We have three functions:
FIRST.
The slope of f(x) is 2
SECOND.
g(x) graph going through (0, -5) and (4, 3), so:
We can find the slope of g(x) as follows:
The slope of g(x) is 2
THIRD.
h(x) passes through (-1, 3), (1, 7) and (3, 11)
We can find the slope of h(x) as follows:
The slope of h(x) is 2
So, it is obvious that the three functions have the same slope 2.

Answer:
The probability of an operating system error given that a failure has ocurred is P(O/E)= 0.19
Step-by-step explanation:
Hello!
There are three different sources of error when a computer system fails:
D: disk drive error. ⇒ P(D)= 0.50
M: computer memory error. ⇒P(M)= 0.20
O: operating systems error. ⇒ P(O)= 0.30
According to the component perdormance standard:
The probability of failure "E", given that there is a disk drive error is P(E/D)= 0.40
The probability of failure "E", given that there is a computer memory error is P(E/M)= 0.6
The probability of failure "E", given that there is a operating system error is P(E/O)= 0.25
You need to calculate the probability of an operating system error given that a failure has ocurred, symbolically:
P(O/E)
To reach the probability of the marginal E you have to add all intersections between the event "E" and the events "D", "M" and "O"
D M O Total
E: P(E∩D); P(E∩M); P(E∩O); P(E)
Using the formula of the conditional probability I'll clear all three intersections using the known probabilities:
General formula: ⇒
P(E∩D)= P(E/D)*P(D)= 0.4*0.5= 0.2
P(E∩M)= P(E/M)*P(M)= 0.6*0.2= 0.12
P(E∩O)= P(E/O)*P(O)= 0.25*0.3= 0.075
P(E)= P(E∩D) + P(E∩M) + P(E∩O)= 0.2+0.12+0.075= 0.395
I hope it helps!
