A die is rolled N times and the results stored in a collection called ROLLS. The die has normal faces, that is, with numbers 1 to 6 inclusive across its sides. The die is considered biased if both the number of rolls (N) is greater than 1000 and the average value is either greater than 3.5 + 100/N or less than 3.5 - 100/N. If there are 1000 rolls or less then it is not known if the die is biased or not. Write pseudo-code to determine whether or not the die is biased using this method and output the verdict.

Consider the following pseudocode which draws a path connecting each point contained in the array POINTS.

Define the term heuristics.

Given a short array of integers of length 2 called myShortArray, write pseudocode to determine and output the biggest and second biggest number.

Given an array of integers of length 5 called myLongerArray, write pseudocode to determine and output the biggest number it contains.

Given an array of integers of length 7 called myArray, write pseudocode to output the sum of the two biggest integers it contains. The algorithm should handle both negatives values and repeated values.

Write an algorithm which outputs every item of a 2D array that is 100 by 100 elements in size

Input the dimensions of a rectangle then print both area and perimeter.

Input 3 numbers and if all three numbers are different then output "distinct", otherwise output "not distinct".

An attribute that forms part of a composite primary key to uniquely identify a record in a table.

An attribute that uniquely identifies a record in a relational database table.

An attribute that is copied to an index data structure in order to optimise query efficiency for those rows / records associated with the copied attribute.

An attribute that corresponds to the value of a primary key in another table for the purpose of creating a link between the two tables.

Define the term population.

Outline one advantage and one disadvantage of Tournament Selection when compared to Truncation Selection.

Given a simple traffic light with a pedestrian crossing button forms an open loop system, outline one way in which traffic light operations may return to normal following a pedestrian crossing event.

Discuss the social implications of monitoring traffic using CCTV.

The Medicare Levy Surcharge (MLS) is a 1-2% levy paid by Australian taxpayers who do not have private hospital cover and who earn above a certain income. The current income threshold is AUD$90,000 for singles and AUD$180,000 for couples / families (2020-2021 financial year). Once Australians earn above these thresholds within a financial year, they must pay the MLS. Given an annual income called INCOME, a boolean flag for having private hospital cover or not called PRIVATE and another boolean flag for being single or not called SINGLE, write pseudocode to output True if eligible for the MLS or False otherwise. For example, a single (SINGLE = true) person who doesn’t have private health insurance (PRIVATE = false) and is earning AUD$120,000 (INCOME = 120000) annually must pay the MLS (output True)

Define the term ubiquitous computing.
