I belive its true but i am not a 100% sure
Answer:
is there some oppsense you can choose from
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).

Answer:
The answer to this question is Control(ctrl).
Explanation:
We use control(ctrl) key when we need to select multiple entities.
So when we want to select more than one sketched entity we need to press and hold the control key on the keyboard when we are selecting the items.
Hence we conclude that the answer to this question is Control(ctrl).
