Answer:
Today's temperature is 5.7 degrees above Bill's normal temperature.
Step-by-step explanation:
Given
Represent the normal temperature with N and today's temperature with T.
Such that:
Required
Determine the temperature above the normal temperature
The interpretation of this is to calculate the difference between Bill's normal temperature and Bill's today temperature.
Represent the difference with D
D is calculated as follows:
Substitute values for T and N
Hence, today's temperature is 5.7 degrees above Bill's normal temperature.

Step-by-step explanation:
Answer:
45% probability that a randomly selected customer saw the advertisement on the internet or on television
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a customer saw the advertisement on the internet.
B is the probability that a customer saw the advertisement on television.
We have that:
In which a is the probability that a customer saw the advertisement on the internet but not on television and 
is the probability that the customers saw the advertisement in both the internet and on television.
By the same logic, we have that:
12% saw it on both the internet and on television.
This means that 
20% saw it on television
This means that 
37% of customers saw the advertisement on the internet
This means that 
What is the probability that a randomly selected customer saw the advertisement on the internet or on television
45% probability that a randomly selected customer saw the advertisement on the internet or on television
