Question 1 When you declare a variable of type Single, it contains 0 by default. True False Question 2 The following line declares an array that can contain whole numbers, with 10 elements. Dim Variables(9) As Integer True False Question 3 Once a variable is declared we can not change the variable's data type. True False Question 4 If A is False and B is True, then A Or B is True because A is False. True False Question 5...
.data # This data will serve as our map between the roman # and the decimal numbers. Here, each list will # serve as our makeshift "array", where the conversion # from decimal to roman will be according to each indice, # i.e. decimalNumeral[i] will dictate romanNumeral[i]. # This also will be useful when converting roman to # decimal, as romanNumeral[i] will dictate decimalNumeral[i] decimalNumeral: .word 1000 100 50 10 5 1 # the decimal map romanNumeral: .asciiz "MDCLXVI" #...

Procedure Part 1: Attributes of Laws and Theories 1 Designate whether each attribute in Data Table 2 is true of a law. If the attribute applies, record an “X” in the “Law” column. If the attribute does not apply, leave the area blank. Data Table 2: Attributes of Laws and Theories Attribute Law Theory X Helps unify a field of study A particular phenomenon always occurs if certain conditions are present Supported by a large amount of data Explains why...
The percentile ranks are very useful when comparing values from two different data sets. True False 3 10 Question 20 (5 points) Consider the following data set: Variable 1: 20 15 14 10 5 5 8 Variable 2: 2 9 5 3 8 10 17 The sample correlation coefficient for this data set is: O 0.18 0.47 0-0.80 0-0.55
Column A contains a generic dataset. Column C is a list of
questions that correspond to the questions below. Column D
indicates which Excel function(s) that question is designed to
teach. Column E is where you will work with the function(s) to
generate the answer to each question. And finally Column F displays
the formula you used to generate your answer in Column E.
To place your answers from Column E into the blanks below, use
the copy/paste keyboard shortcut:...
Create a Python class named Phonebook with a single attribute called entries. Begin by including a constructor that initializes entries to be an empty dictionary. Next add a method called add_entry that takes a string representing a person’s name and an integer representing the person’s phone number and that adds an entry to the Phonebook object’s dictionary in which the key is the name and the value is the number. For example: >>> book = Phonebook() >>> book.add_entry('Turing', 6173538919) Add...
