Let X be the number of cars recovered from stolen cars. Let n be the total number of stolen cars and p be the probability that car will be recovered.
Given: n=10, x=5
It is given that a car with a certain protection system will be recovered 87% of the time. It means probability of recovering a car is p=0.87
Probability that 5 out of 10 stolen cars will be recovered is
P(X=x ) =
P(X=5) =
P(X=5) = 0.0047
The probability that exactly 5 out of 10 stolen cars will be recovered is 0.0047
Answer:
<em>The magnitude of the velocity will be 60 m/s.</em>
<em>The distance covered is 3,600 m</em>
Step-by-step explanation:
<u>Constant Acceleration Motion</u>
It's known as a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
If a is the constant acceleration, vo is the initial speed, vf the final speed, and t the time, the following relation applies:
The distance traveled by the object is calculated as:
The bus starts from rest, i.e. vo=0, the acceleration is a=0.5 m/s^2. The magnitude of the velocity at t=2 minutes = 120 seconds is:
The magnitude of the velocity will be 60 m/s.
The distance covered during that time is:
x = 3,600 m
The distance covered is 3,600 m
See the attached picture.
