Asurvey of teenagers found the music preferences listed. country jazz rock classical new age other 12 5 7 6 6 4 if you pick a teenager at random, what is p(rock)? a. b. c. d. 1

Probability that randomly selected teenager like Rock music is 0.175

Step-by-step explanation:

Given:

Type of musics teenagers like = Country, Jazz, Rock, Classical, New Age , Other

Number of teenagers like Country = 12

Number of teenagers like Jazz = 5

Number of teenagers like Rock =  7

Number of teenagers like Classical = 6

Number of teenagers like New age = 6

Number of teenagers like Other = 4

To find: Probability that randomly selected teenager like Rock music.

We know that,

Total Number of outcome = Total number of teenagers surveyed.

                                           = 12 + 5 + 7 + 6 + 6 +4

                                           = 40

So, Probability =

Therefore, Probability that randomly selected teenager like Rock music is 0.175

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer:
