Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. she found that the restaurant was playing country 11 times, rock & roll 17 times, and blues 8 times. use the observed frequencies to create a probability model for the type of music the restaurant is playing the next time mahnoor walks in.

The next time Mahnoor visits the restaurant, there is:

>>>>31 % chance for country music

>>>>47% chance of rock & roll

>>>>8% chance of blues

Step-by-step explanation:

Total visits of Mahnoor = 36

Music played  |  Frequency  |  Probability

country            |  11                 |  11/36 = .31

rock & roll        |  17                |  17/36 = .47

blues                |  8                 |  8/36 = .22

answer: i believe it’s 245.04

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
