4 omplete the answer omplete the student s answer so that it would be awarded full marks. Ratio and proportion train was carrying some passengers. The ratio of the number of male passengers to the number of female passengers was 5 : 4 Each passenger had a first-class ticket or a standard ticket. of the female passengers had first-class tickets. 4 female passengers had standard tickets. The maximum number of tickets available for this train was 600 Show that more than 5% of the tickets have not been sold. You must show how you get your answer. (5 marks) of the female passengers had standard tickets. If the question asks you to show omplete the student s answer so that it would be awarded full marks. 0 Roberta invests 000 in a savings account for 4 years. The account pays compound interest of x% per year. t the end of 4 years Roberta s investment is worth Work out the value of x. x x% = 00 that something is true, make sure you show all the steps in your working. Hint First write the multiplier that represents an increase of x%. ( marks) x = 5

5 Geometry and measures Re-order the answer Rearrange the working out into the most logical order by numbering each part. Here is a triangle D. Work out the size of angle D. = sin sin sin 44 =.6 9. =.9 = 6. sin 44 sin =.6 9. pencil case is a cuboid with base measuring 5 cm by 9 cm. The height of the cuboid is 6 cm. Work out the length of the longest pencil that will fit in the case. Give your answer in centimetres, correct to the nearest millimetre. =.49 cm m m D Rearrange the working out into the most logical order by numbering each part. 5 cm 6 cm 9 cm (5 marks) ( marks) =.5 cm = 06 60

6 Mark the answer Use the mark scheme to assign a mark to the answer. Give a reason for your mark. Probability and statistics The table shows information about the annual turnover of a company. Year Turnover ( millions) (a) Draw a time series graph to represent this data. nswer ll points plotted correctly I would award the answer (b) Write down the type of correlation. Upwards nswer positive I would award the answer Turnover (millions) for at least 5 points plotted correctly Notes for all points plotted correctly ( sq tolerance) for positive oe Year Notes John is doing a survey to find out how much time students spend playing sport. He is going to ask the first 0 boys on the register for his Mathematics class. This may not produce a good sample for John s survey. Give two reasons why. 0 0 out of marks because 0 out of mark because Use the mark scheme to assign a mark to the answer. Give a reason for your mark. The number of boys he is asking is too small and he is only asking boys. ( marks) ( marks) nswer correct reasons Notes for one acceptable reason from bias relating to gender/bias relating to age/from relating to Maths students/sample size is too small/sampling is not random for second acceptable reason I would award the answer out of marks because 7
