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

The next time Mahnoor visits the restaurant, there is:

--31 % chance for country music

--47% chance of rock & roll

--22% chance of blues

Completed question;

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.

Step-by-step explanation:

Given;

The number of times they were playing each type of music;

Country = 11 times

Roll = 17 times

Blues = 8 times

Total visits of Mahnoor = 11+17+8 = 36

Developing a frequency table and probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Probability = number of favourable outcomes ÷ total number of outcomes.

Music played  |  Frequency  |  Probability

country            |  11                 |  11/36 = .31 or 31%

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

blues                |  8                 |  8/36 = .22 or 22%

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
