Step-by-step explanation:

Let U represent the set of people in a certain community who were asked if they subscribe to an information source. Let D ={ x ∈ U | x subscribes to The Daily Informer } and N ={ x ∈ U | x subscribes to News Magazine } (Assume these sets are not disjoint.) Write the set that represents the set of people surveyed who subscribe to exactly one of the two news sources given.

a. N ∪ D
b. ( N c ∩ D ) ∪ ( N ∩ D c )
c. N c ∩ D
d. ( N ∩ D )c
e. ( N c ∪ D ) ∩ ( N ∪ D c )

Answers

Answer:

b. [tex]( N^c \cap D ) \cup ( N \cap D^c )[/tex]

Step-by-step explanation:

Here,

N = { x ∈ U | x subscribes to News Magazine },

D = { x ∈ U | x subscribes to The Daily Informer },

Such that N∩D ≠ ∅,

Now, the number of the set of people surveyed who subscribe only News Magazine

= Subscribe News Magazine and not Daily Informer

= [tex]N\cap D^c[/tex]

Similarly, the number of the set of people surveyed who subscribe only Daily informer

= Subscribe Daily informer and not subscribe News Magazine

= [tex]D\cap N^c[/tex]

Hence,  the set of people surveyed who subscribe to exactly one of the two news sources given

= Subscribe News Magazine and not subscribe Daily Informer or subscribe Daily informer and not subscribe News Magazine

[tex]= (N\cap D^c)\cup (D\cap N^c)[/tex]

[tex]=( N^c \cap D ) \cup ( N \cap D^c )[/tex]

Final answer:

The set of people who subscribe to exactly one of the two news sources is represented by ( Nc ∩ D ) ∪ ( N ∩ Dc ). This includes people who subscribe to The Daily Informer but not News Magazine and those who subscribe to News Magazine but not The Daily Informer.

Explanation:

The set that represents the set of people surveyed who subscribe to exactly one of the two news sources, The Daily Informer (D) or News Magazine (N), can be written as ( Nc ∩ D ) ∪ ( N ∩ Dc ). The notation Nc represents the set of all people who do not subscribe to News Magazine and Dc represents the set of all people who do not subscribe to The Daily Informer. Thus, Nc ∩ D represents those who subscribe to The Daily Informer but not News Magazine, while N ∩ Dc represents those who subscribe to News Magazine but not The Daily Informer. The union of these two sets, denoted by ∪, represents the complete set of people who subscribe to exactly one of the two news sources.

A plane traveled from California and back. It took one hour on the way out than it did on the way back. The plane's average speed out wad 300 mph. The speed on the way back was 350mph. How many hours did the trip out take?

Answers

Answer:

6 hours

Step-by-step explanation:

You can set up a chart:

      R       T     D

O  300   1+x   ~                  O=out   B=back R=Rate/Speed T=time D=distance

B   350   x      ~

                                                                                                                       

The distance is the same. On the way out the speed was 300 mph, so you can see where that is on the chart. And the speed back was 350 mph. It took an extra hour on the way out than on the way back, so you can call the way back's time x and then say the way out's time was x+1.

It's important to know that R times T = D

Therefore we can say 300(x+1)=D and 350(x)=D

Since the distance is the same, 300(x+1)=350(x)

                                                                                           

Solve:

300(x+1)=350x

300x+300=350x

50x=300

x=6

Therefore, the trip out took 6 hours.

I hope that helps! :)

Answer:the trip out took 7 hours

Step-by-step explanation:

Distance travelled = speed × time

Let t represent the time it took the plane to travel from California.

It took one hour on the way out than it did on the way back. This means that the time it took the plane to return would be t - 1

The plane's average speed out ward 300 mph. Distance travelled when going out would be

300 × t = 300 = 300t

The speed on the way back was 350mph. Distance travelled when returning would be

350(t - 1) = 350t - 350

Since the distance is the same, it means that

300t = 350t - 350

350t - 300t = 350

50t = 350

t = 350/50 = 7

Time taken to go out is 7 hours
