The answer is a. im pretty positive but if im wrong super sorry
To convert binary fraction to decimal fraction, we first write the given
.1011 (base 2)
The process of conversion is to break down to its decimal constituent,
.1011 (base 2) = (1*2^-1)+(0*2^-2)+(1*2^-3)+(1*2^-4)
.1011 (base 2) = 0.5 + 0 + 0.125 + 0.0625
.1011 (base 2) = 0.6875 (base 10)
<em>ANSWER: 0.6875 (base 10)</em>

sorry that all device i know
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).
