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: 75% off the original price.
Step-by-step explanation:Say an item is $100. 50% off $100 is of coarse $50.
Now 50% off that price is $25.
So the new price is now $25 which is 75% off.
I think it’s B I am not sure if it’s wrong sorry :(
Answer:
Step-by-step explanation:
a = 35 feet
b = 54 feet
h = 28 feet
![Area=\frac{[a+b]*h}{2}\\\\=\frac{[35+54]*28}{2}\\\\=\frac{89*28}{2}\\\\=89*14\\\\](https://tex.z-dn.net/?f=Area%3D%5Cfrac%7B%5Ba%2Bb%5D%2Ah%7D%7B2%7D%5C%5C%5C%5C%3D%5Cfrac%7B%5B35%2B54%5D%2A28%7D%7B2%7D%5C%5C%5C%5C%3D%5Cfrac%7B89%2A28%7D%7B2%7D%5C%5C%5C%5C%3D89%2A14%5C%5C%5C%5C)
= 1246 square feet
