Answer:
50%
Explanation:
The markup is the difference between the selling price and the cost price. If the mark up is greater than zero, it means there is a profit, if the markup is less than 0, it means there is a loss and if the markup is equal to 0, it means there is breakeven.
Percentage markup = (markup/cost price) * 100%
Selling price - cost price = markup
15 - cost price = 5
cost price = 10
Percentage markup = (markup/cost price) * 100% = (5/10) * 100% = 50%
Answer:

Explanation:
I'm not sure just taking a guess cuz I'm bored lol
Answer:
- import statistics
- def st_dev(file_name):
- with open(file_name) as file:
- data = file.readlines()
- numList = []
- for x in data:
- numList.append(int(x))
-
- return statistics.pstdev(numList)
- print(st_dev("text1.txt"))
Explanation:
The solution code is written using Python.
To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).
Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.
We test the function by passing a file which hold a list of integer values in each line (Line 12).
