Answer:
Following are the solution to the given points:
Step-by-step explanation:
In point 1:
The Reflexive closure:
Relationship R reflexive closure becomes achieved with both the addition(a,a) to R Therefore, (a,a) is
Thus, the reflexive closure:
In point 2:
The Symmetric closure:
R relation symmetrically closes by adding(b,a) to R for each (a,b) of R Therefore, here (b,a) is:
Thus, the Symmetrical closure:
Answer:
Diego playlist has 36 songs in rock genre, 9 songs in Country genre, 27 songs in hip hop genre and 24 songs in electronica genre.
Step-by-step explanation:
Given:
Total Songs on playlist = 90

So Number of songs in rock genre =
country = 10%
So Number of songs in country genre =
hip hop = 30%
So Number of songs in hip hop genre = .
and rest is electronica genre.
Number of songs in electronica genre can be calculated by Subtracting Number of songs in rock genre and Number of songs in country genre and
Number of songs in hip hop genre from Total number of songs.
framing in equation form we get;
Number of songs in electronica genre =
Hence Diego playlist has 36 songs in rock genre, 9 songs in Country genre, 27 songs in hip hop genre and 24 songs in electronica genre.
