2. A disc jockey plays a variety of music at public events. Each hour she
plays 2 classic rock songs, 6 bluegrass songs, 5 popular songs, and 2 rap
songs. What is the probability as a percentage that the first song played
will be a bluegrass song?*

40%

Step-by-step explanation:

6+2+5+2=15

15= 100%

Use proportions

600=15x

600/15 = 15x/15

x= 40

40%

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
