A20-a18=a1+19d-a1-17d=2d =281-97
so
d=92
Answer:
x > 10/7 or x > 1 3/7
Step-by-step explanation:
First simplify the left side of the inequality.
6x+ 1/4 (4x+8)> 12
6x+x+2>12
7x+2>12 Next, using the property of inequality, subtract two from both sides.
7x>10 Now divide by 7 to solve for x.
x>10/7 or x> 1 3/7
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)
No because she runs up yes but she also ran down witch means she went exactly 0
