Mekala has an mp3 player called the jumble. the jumble randomly selects a song for the user to listen to. mekala's jumble has 4 techno songs, 2 country songs, and3 jazz songs on it. mekala plans to listen to 270 songs.
complete the following statement with the best prediction.
mekala will listen
choose from one of the following options.

a) exactly 60 country songs
b) close to 60 country songs but probably not exactly 60country songs
c)exactly 210 country songs
d)close to 210 country songs but probably not exactly 210 country songs

Mekala Jumble has 4 techno songs, 2 country songs, and3 jazz songs on it.

Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3

Whatever be total  number of songs, let the number of techno songs, country songs,and jazz songs be  4 x,  2 x, and  3 x.

Total number of songs that Mekala plans to Listen = 2 70

Then , 4 x + 2 x + 3 x= 270

9 x = 270

Dividing both sides by 9, we get

x = 30

So, Number of techno songs = 4 × 30= 120

Number of techno songs = 2 × 30= 60

Number of jazz songs = 3 × 30= 90

Option (b) b) Close to 60 country songs but probably not exactly 60 country songs  ,is true option regarding number of songs listen by Mekala.

plz give brainliest

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
