You must have:
Mathematical Formulae and Statistical Tables (Green), calculator,
Decision Mathematics Answer Book (enclosed)
Candidates may use any calculator permitted by Pearson regulations.
Calculators must not have the facility for symbolic algebra manipulation,
differentiation and integration, or have retrievable mathematical formulae
stored in them.
Instructions
Use black ink or ball-point pen.
•
If pencil is used for diagrams/sketches/graphs it must be dark (HB or B).
Write your answers for this paper in the Decision Mathematics answer book
• provided.
Fill in the boxes at the top of the answer book with your name,
centre number and candidate number.
•
Do not return the question paper with the answer book
Answer all questions and ensure that your answers to parts of questions are clearly
•
labelled.
Answer the questions in the answer book provided
– there may be more space than you need.
• You should show sufficient working to make your methods clear. Answers without

The list of ten numbers above is to be sorted into descending order.
(a) Perform a quick sort on the list to obtain the sorted list. You should show the result
of each pass and identify the pivots clearly.
(4)
A list of n numbers is to be sorted into descending order using bubble sort.
(b) Determine, in the worst case, the total number of comparisons required to sort the
list. Give your answer as a simplified expression in terms of n.
(2)
The following algorithm determines an approximation to the value of e
Step 1 Start
Step 2 Let a = 1
Step 3 Let b = 1
Step 4 Let c = 1
Step 5 Let d = a
Step 6 Let c c b
Step 7 Let d d 1
c
Step 8 If b = 6 go to Step 11
Step 9 Let b = b + 1
Step 10 Go to Step 6
Step 11 Output d
Step 12 Stop
(c) Complete the table in the answer book to show the results obtained at each step of
the algorithm.
(3)
(d) Calculate, to 3 significant figures, the percentage error in using the value found in
(c) to approximate the value of e
