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
By definition, the gravitational force is given by:
Where,
m1 and m2: are the masses of the objects
G: is the gravitational constant
r is the distance between the objects' centers
The vertical asymptote of the function occurs when the denominator is equal to zero.
We have then:
In this context, it means that physically, the distance between the center of the objects can not be equal to zero (which is logical).
Answer:
Center = (7, - 5)
Radius = 3

===========================================================
Work Shown:
Angle theta is between 0 and pi/2, so this angle is in quadrant Q1.
Square both sides of the given equation
Then use the pythagorean trig identity to get
