Answer:
B
Step-by-step explanation:
Given
f(x) =
The denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.
x + 2 = 0 ⇒ x = - 2
The equation of the vertical asymptote is x = - 2
Answer:
There is a 40% probability that a randomly selected traveler whochecks work email also uses a cell phone to stay connected.
Step-by-step explanation:
a) What is the probability that a randomly selected traveler whochecks work email also uses a cell phone to stay connected?
The problem states that 40% of the travelers on vacation check work email. And 16% of them check both work email and use a cell phone.
So, the probability is the division of those who use both email and cellphone by those who use email.
There is a 40% probability that a randomly selected traveler whochecks work email also uses a cell phone to stay connected.
