Answer:
P(O|R)
Step-by-step explanation:
The conditional probability notation of two events A and B can be written as either P(A|B) or P(B|A).
The '|' sign is read as 'given'. So, P(A|B) is read as the probability of event A given event B which implies that it is the probability that event A will occur given that event B has already occurred.
In the question,
Event R = Person lives in the city of Raleigh
Event O = Person is over 50 years old
The statement says, 'given that the person lives in Raleigh' which means that event R has already occurred and we need to find the probability of event O (the randomly chosen person is over 50 years old).
Hence, this statement can be given in conditional probability notation as
P(O|R)
Answer:
Therefore the height of the tower is 101.79 m.
Step-by-step explanation:
The ratio of the height of an object to the shadow of the object is always constant at certain time.
Given that,the length of the pole is 3.5 m and it casts a shadow that is 1.47 m long.
The length of shadow that castes by a tower is 42.75 m long.
Here h₁= 3.5 m, s₁=1.47 m, h₂= ? and s₂=42.75 m
⇒3.5 ×42.75 = h₂× 1.47
⇒h₂ = 101.79 m (approx)
Therefore the height of the tower is 101.79 m.
Answer:
parallel
Step-by-step explanation:
no matter how far the lines stretch, they will all never meet, so they are all parallel
400 miles per hour is a rate. For every hour, the airplane travels four hundred miles.
Knowing this, If the plane travels for three hours, we use a simple multiplication equation to represent this problem.
400 x 3 = 1200
The plane traveled 1200 miles, if it traveled at a speed of four hundred miles for three hours.
