Answer:
Someone can make a histogram instead of a bar chart if distributions of variables are need to be represented and if data is quantitative.
Explanation:
Histograms are drawn to represent distributions of variables whereas bar charts are used to compare various variables. Histograms plot quantitative data whereas bar charts plot categorical data.
So, someone can make a histogram instead of a bar chart if distributions of variables are needed to be represented and if data is quantitative.
Answer:
TAX_RATE = 0.20
STANDART_DEDUCTION = 10000.0
DEPENDENT_DEDUCTION = 3000.0
gross_income = float(input("Enter the gross income: "))
number_of_dependents = int(input("Enter the number of dependents: "))
income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents)
tax = income * TAX_RATE
print ("The income tax is $" + str(round(tax, 2)))
Explanation:
Define the <em>constants</em>
Ask user to enter the <em>gross income</em> and <em>number of dependents</em>
Calculate the <em>income</em> using formula (income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents))
Calculate the <em>tax</em>
Print the <em>tax</em>
<em />
round(number, number of digits) -> This is the general usage of the <em>round</em> function in Python.
Since we need <u>two digits of precision</u>, we need to modify the program as str(<u>round(incomeTax, 2</u>)).
Answer:
The answer to this question is given below in the explanation section.
Explanation:
This question is about what is a good analogy for explaining the actions of a compiler? The correct option is <u> automatic programming of kitchen devices
.</u>
<u>
</u>
a hybrid ability of a car to use multiple energy sources (false)
this analogy is not correctly mapped on the compiler, becuase the compiler can be designed only for one type of language, for example, the program that calculates the average of students number can be easily programmed in C++ and in C#. But you cannot compile the C# program in C++ compiler and vice versa.
a street map of a local subdivision (false)
Because you can design a compiler for a not specific subdivision of programming.
an interpreter who speaks several languages
it is not an analogy, however, an interpreter can handle only one type of language.
an automatic programming of kitchen devices (true)
This is a good analogy of compiler because you give input to the device and that device based on your input gives you back an output. Similarly, you give input to the compiler in form of language syntax, and it automatically give you output based on your input.
