Answer:
x = -1/12
Step-by-step explanation:
q(x) = 12x − 3
q(x) = −4
-4 = 12x − 3
12x - 3 = -4
12x = -4 + 3
12x = -1
x = -1/12
Answer:
53.85% probability the text books were shipped by truck
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Textbooks lost.
Event B: Shipped by truck.
40% of the packages sent by truck.
This means that
3.5 percent of the packages carried by truck have been lost.
This means that
Probability package is lost:
60% probability it is sent by rail. Of those, 2% are lost.
40% sent by truck. Of those, 3.5% are lost.
So
What is the probability the text books were shipped by truck
53.85% probability the text books were shipped by truck
