A radio disc jockey has 8 songs on this upcoming hour's playlist: 3 are rock songs, 3 are reggae songs, and 2 are country songs.
sashaice [31]

Answer:

The answer is 9/64. Also #djgirlpower

Step-by-step explanation:

9/64 is the equivalent of 3/8 • 3/8, which is the probability of the dj picking a reggae song once, and then again. That is most likely the case, except if the song that is played is removed from the collection of not-yet-played songs. Otherwise, I’m pretty sure if that’s the case, it would be 3/8 •2/7. Hope this helped :)

What is the surface area of a square pyramid with a base perimeter of 60 inches is and a slant height of 13 inches
pentagon [3]

Answer:

615 in^2

Step-by-step explanation:

The base of each triangle is 60/4 = 15 in. and the height of each triangle is 13 in.  One triangle = .5bh = .5(15)(13) = 97.5.  The lateral area = 4(97.5) = 390.  The area of the square base is 15(15) = 225.  The total area = 390 + 225 = 615 sq. in.
