Answer:
<div>
Explanation:
The div tag explicitly called the division tag is an extremely important tag in Hypertext Markup Language and Cascading Style Sheets ecosystem. Like most of the other tags used during writing and styling web documents, the div tags plays an important role as it serves as a container which is capable of holding several HTML elements such as the head, body , paragraph tags and so on. All elements within the div tags can be easily styled using the same CSS style specification without having to take the more singular and tedious approach. They also aid fast manipulation using compatible languages. Hence, using the cajas attribute, several elements within a div can be styled at the same time. Also note that , line breaks are automatically placed before and after a tag.
Hence, the div tag is the most appropriate answer.
Answer:
- import math
-
- def standard_deviation(aList):
- sum = 0
- for x in aList:
- sum += x
-
- mean = sum / float(len(aList))
-
- sumDe = 0
-
- for x in aList:
- sumDe += (x - mean) * (x - mean)
-
- variance = sumDe / float(len(aList))
- SD = math.sqrt(variance)
-
- return SD
-
- print(standard_deviation([3,6, 7, 9, 12, 17]))
Explanation:
The solution code is written in Python 3.
Firstly, we need to import math module (Line 1).
Next, create a function standard_deviation that takes one input parameter, which is a list (Line 3). In the function, calculate the mean for the value in the input list (Line 4-8). Next, use the mean to calculate the variance (Line 10-15). Next, use sqrt method from math module to get the square root of variance and this will result in standard deviation (Line 16). At last, return the standard deviation (Line 18).
We can test the function using a sample list (Line 20) and we shall get 4.509249752822894
If we pass an empty list, a ZeroDivisionError exception will be raised.
Software is also called a program or an application.
