<span>The same question as the latter,
Pressure and Force
Density and mass
Force and acceleration
Proportional linear relationship introduces a direct variation between the variables involved meaning when one increase the other also increases. The greater the amount of force, the greater is the pressure is an example.
It
introduces the relationship between two variables and is called
correlation. Proportionality or variation is state of relationship or
correlation between two variables It has two types: direct variation or proportion which
states both variables are positively correlation. It is when both the
variables increase or decrease together. On the contrary, indirect variation or proportion indicates
negative relationship or correlation. Elaborately, the opposite of what
happens to direct variation. One increases with the other variables,
you got it, decreases. This correlations are important to consider
because you can determine and identify how two variables relates with
one another. Notice x = y (direct), y=1/x (indirect)</span>

The complete question is shown on the first uploaded image
Answer:
The correct option is d
Step-by-step explanation:
From the question we are told that
The set of people in a certain community who were asked if they subscribe to an information source is U
The set that subscribes to The Daily Informer is D
The set that subscribe to News Magazine is N
Here the universal set is U
Now the word at least here means that the person can subscribe to one or two of the information source , but the person cannot subscribe none of the information source
Now to get the set that represents the set of people surveyed who subscribe to at least one of the two news sources , we need to carry out a union operation on the sets representing the two news source , this can be mathematically represented as
So the sets that will contain all the people in the community that subscribe to at least one of the news source is L
'is' in mathematics means equal
'of' in mathematics means multiplication
