What is the probability of getting a sum of 7? 1/6 1/8 1/4 1/12 1/9 The pairs that give a sum of 7 are (1,6), (2,5), (3,4), (4,3), (5,2), (6,1). There are 6 such outcomes out of 36 total, so the probability is 6/36 = 1/6. 2 / 14What's the average number of steps taken over a week? (Round off to the nearest 10) 9760 9200 9786 9640 10000 Steps: 9000, 8000, 9000, 8500, 10000, 12000, 11000.Average = (9000 + 8000 + 9000 + 8500 + 10000 + 12000 + 11000) / 7= 9642.85 steps.Rounding off to nearest 10 -> 9640 3 / 14The volume of this object is 10m³. What is the total surface area? 32m² 20m² 30m² 36m² 10m² There are 10 cubes and the total volume is 10m³The volume of each cube is 1cm³ ie. each side is 1m.We know each flat face of the cube is a square - the surface area of each face is 1m x 1m = 1m²Total surface area = Number of visible cube faces x 1m²If you look at the object from all sides, top (6) + bottom (6) + left (4) + right (4) + front (5) + back (5) = 30 faces with surface area of 1m² eachHence, total surface area = 30 x 1 = 30m² 4 / 14George has written an expression. When x=3, the value of the expression is 15.Which of the following could NOT be his expression? x³ -12 x² + 6 5x² / 3 x (x+2) 3x + 3² 3x + 3² = 9 + 9 = 18All other expressions equal to 15 5 / 14Find the value of * 7 0 1 5 3 6 / 14Which of the following values is the smallest? 3.6% 0.05 1/15 3.49% 1/25 To determine which number is the smallest, we need to convert all the values to the same format (ie. decimal format) for easy comparison.A. 3.6% = 3.6 / 100 = 0.036 B. 1/25 = 0.04 C. 0.05 D. 3.49% = 3.49 / 100 = 0.0349 E. 1/15 = 0.0667Now we can compare the values: A. 0.036 B. 0.04 C. 0.05 D. 0.0349 E. 0.0667The smallest value is 0.0349 So, the answer is D. 3.49% 7 / 14What fraction of the shape is shaded? 3/10 9/25 6/25 1/5 2/25 8 / 14The image on the left is rotated clockwise by 90 degrees and then flipped horizontally (as if reflected on a vertical mirror). Which one is the resulting image? B A E D C 9 / 14The end points of five lines are shown in the answer options below. Which line is parallel to the line in the diagram? (1, 6) (6, 2) (2, 6) (5, 2) (1, 7) (5, 2) (1, 6) (5, 3) (1, 6) (5, 2) 10 / 14The pie chart shows the proportion of different colours of cars in a showroom. There are 200 cars in the showroom.How many red cars are there? 110 84 94 42 52 Sum of all colours of cars should be 100% ie. 8% + 30% + 20% + Red Cars % = 100% ie. 58% + Red Cars % = 100% % of Red Cars = 100-58 = 42%There are 200 cars in the showroom.Hence total number of red cars = 42% of 200 = 84 11 / 14Sam has £8 more than Rita and £6 less than Lisa. Altogether they have £40. How much money does Lisa have? £6 £15 £13 £14 £20 Let's say Sam has X poundsSo, Rita has X - 8 poundsLisa has X + 6 poundsAltogether they have £40Given the above, X + (X - 8) + (X + 6) = 403X - 2 = 403X = 42X = 14Sam has £14, Rita has X - 8 = £6 , Lisa has X + 6 = £20 12 / 14Julio jumps 6.656m in a long jump competition. What is the length of the jump to the nearest cm? 6.7m 6.66m 6.65m 6.6m 6.656m 13 / 14What is the weight of each block? 100Kg 60Kg 40Kg 120Kg 80Kg 5 blocks weigh 400Kg So, each block weigh 400 ÷ 5 = 80Kg 14 / 14A pot contains 45 marbles. 25 of the marbles are blue, 5 of the marbles are green, and the rest of the marbles are red. If a marble is drawn at random, what is the probability that it is red? 1/3 1/6 1/5 2/5 1/2 Number of red marbles = 45 - 25 (blue) - 5 (green) = 15Probability of picking a red marble = 15 / 45 = 1/3
