Answer: a continuous random​ variable

Step-by-step explanation:

<u><em>Can you count the distance it traveled?</em></u> You can't, so it couldn't be discrete because you can count discrete variables.

<u><em>Can you measure the distance it traveled? </em></u>You sure can, that makes it a continuous random variable.

<u><em>Do you know the exact distance it's going to travel?</em></u><u> </u>You won't, therefore it's a random variable since you don't know the value beforehand.

igor_vitrenko [27]
Dance (D) + Rap (R) + Country (C) = 1,075 songs
D = 3R
C = R + 105

RAP
Subtract 105 from both side:
(3R) + R + (R + 105) = 1,075
                          -105      -105

Combine all R's:
(3R) + R + R = 970
5R = 970

Divide both sides by 5:
5R = 970
/5         /5
R = 194

DANCE
D = 3(R)
D = 3(194)
D = 582

COUNTRY
C = R + 105
C = 194 + 105
C = 299

So, the DJ has a total of 194 rap songs, 582 dance songs, and 299 country songs.
