Answer:
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%
Answer:
5n-9
Step-by-step explanation:
You can factor (15n^2-27n) to be (3n)(5n-9). When you divide this expression by 3n, 3n/3n=1, and you are left with just 5n-9. Hope this helps!

Individual : a male in the United States
Variable : income
Population : All males in the United States
Sample : 2500 males of which the information is collected
Parameter : Median income of males in the U.S
Statistic : Median income of the 2500 males sampled
- Any quality, amount, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable.
- A sample is a subset of units chosen to represent all the individuals in a population. Because just a portion of the population was counted, it is only a partial enumeration. To estimate the characteristics of the total population of interest, data from the sampled units is used.
- A statistic is a numerical representation of a sample, whereas a parameter is a numerical representation of the entire population.
