The tool used by data analysts to create a clean and consistent visual appearance for their spreadsheets is called <u>clear formats</u>.

A database refers to an organized or structured collection of data that is typically stored on a computer system and it can be accessed in various ways. Also, each database has a unique formatting and this may result in data inconsistency.

In Computer science, a clean data is essential in obtaining the following:

  • Data consistency
  • Data integrity
  • Reliable solutions and decisions.

Furthermore, spreadsheets are designed and developed with all kinds of tools that can be used to produce a clean data that are consistent and reliable for analysis.

In this context, clear formats is a kind of tool that is used by data analysts to create a clean and consistent visual appearance for their spreadsheets.

[20 pts] Write the function rectangle(perimeter, area), which takes two positive integers, perimeter and area. It returns an int
MrRissso [65]

Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.

Answer:

import math

def rectangle(perimeter, area):

   l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4

   l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4

   l2_1 = area/l1_1

   l2_2 = area/l1_2

   print(l1_1,l2_1)

   print(l1_2,l2_2)

   if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:

       return(int(max(l1_1,l2_1)))

   elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:

       return(int(max(l1_2,l2_2)))

   else:

       return(None)

Explanation:

  • We import math to make basic operations
  • We define the rectangle function that receives perimeter and area
  • We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
  • We calculate the second root of the quadratic equation for the same side (l1_2)
  • We calculate the second side of the rectangle using the first root on w = a/h
  • We calculate the second side of the rectangle using the second root on w= a/h
  • We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
  • If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
  • if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found

Fix the regular expression used in the rearrange_name function so that it can match middle names, middle initials, as well as do
marysya [2.9K]

Answer:

name = re.search(r"^([\w \.-]), ([\w \.-])$", list_name)

Explanation:

Regular expression is used to simplify the mode in which items in a data structure are for. It uses wildcards as shortcuts.

The python module for regular expression is 're'. The import statement is used to get the module and the search() method of the module is used to get the one matching item while the findall() method is used to get a list of all the matching items in a data structure.
