Let R be the event that a randomly chosen person lives in the city of Raleigh. Let O be the event that a randomly chosen person
Anit [1.1K]

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)

F(x) = 3. 7 – 2x g(x) = 0. 25x – 5 What is f(x) g(x)? h(x) = 3. 95x – 7 h(x) = 8. 7 – 2. 25x h(x) = –1. 3 – 1. 75x h(x) = 3. 95

To solve the problem we must know about Like Terms.

<h3>What are Like Terms?</h3>

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

The solution to the problem is (-1.7x-1.3).

Given to us

  • f(x) = 3.7 - 2x
  • g(x) = 0.25x - 5

To find

f(x) + g(x)

To solve the problem we will put the functions as given to us,

f(x)+g(x)\\= ( 3.7 - 2x)+( 0.25x - 5)

Open brackets,

=3.7 - 2x+ 0.25x - 5

<h3>Like Terms</h3>

Solve the like terms,

=3.7 - 2x+ 0.25x - 5\\\\=0.25x-2x-5+3.7\\\\=-1.75x-1.3

Hence, the solution to the problem is (-1.7x-1.3).
