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.
Answer:
The perfect -square trinomial
(9y+7)²
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomial equation
81 y² + 126 y +49
⇒ 9² y² + 2(9)(7)y + 7²
⇒ (9y)² + 2(9)(7)y +7²
we will use formula
(a+b)² = a² + 2ab +b²
⇒ (9y+7)²
<u><em>Final answer:-</em></u>
The perfect -square trinomial
(9y+7)²
