The answer is 14, 0+4 is 4 and then you put the 1 infront of the 4 making 14
Answer:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
The probability of finding a value higher than x is:
Average repair time of 2 hours
This means that
What is the probability that the repair time takes between 2 to 4 hours
More than 2:
Less than 4:
Between two and four:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
1/4 to 1/2 percentage of change is 1/2
Since 1 Euro is 1.321 in American money you must convert the value to $200
Divide 200 by 1.321
you get
151.40 in Euros
