To find the total percentage of students who scored between 50 and 90 percent, add the frequencies of the scores from 50 to 90. The frequencies are: 7 (50) + 3 (60) + 10 (70) + 1 (80) + 2 (90) = 23 students.
To find the value of m, we need to know the total number of students. The total frequency is 2 + 3 + 4 + m + 7 + 3 + 10 + 1 + 2 = 32. Therefore, m = 32 - (2 + 3 + 4 + 7 + 3 + 10 + 1 + 2) = 32 - 32 = 0.
The mark scored by the most students is 70, with a frequency of 10.
The area of one tile can be calculated by converting the dimensions from centimeters to meters. A tile measuring 20 cm x 20 cm is 0.2 m x 0.2 m. Therefore, the area is 0.2 m * 0.2 m = 0.04 square metres.
First, calculate the area of the bedroom floor: 6 m * 5 m = 30 square metres. Then, divide the total area by the area of one tile: 30 m² / 0.04 m² = 750 tiles.
If 750 tiles are needed and each tile costs $0.80, the total cost is 750 * $0.80 = $600.
The radius of a circle is half of the diameter. Therefore, the radius is 28 cm / 2 = 14 cm.
Average speed is calculated by dividing the total distance by the total time. Therefore, average speed = 120 km / 2 hours = 60 km/h.
The polygon is a regular hexagon, as it has six equal sides and angles.
The formula for the interior angle of a regular polygon is (n-2) * 180° / n, where n is the number of sides. For a hexagon, n = 6, so the angle x = (6-2) * 180° / 6 = 120°.
An angle measuring 120° is classified as an obtuse angle, as it is greater than 90° but less than 180°.
Simple interest can be calculated using the formula: Interest = Principal x Rate x Time. For example, if Sharon borrowed $4,500 at 9% for 2 years, the interest would be $4,500 x 0.09 x 2 = $810.
To find the total amount to be paid back, add the principal to the interest. Total amount = Principal + Interest = $4,500 + $810 = $5,310.
In the Answer Booklet, circle the letter of the best answer. If you change your mind, cross out the first circle and circle the new choice. If you change your mind again, cross out the second circle and tick your first answer. No marks will be given if more than one letter is circled.
The suggested time for completing Section A, which consists of twenty multiple choice questions, is 36 minutes.
The total mark allocation for the exam is 100 marks, with 40 marks for Section A and 60 marks for Section B.
Writing neatly and clearly is important to ensure that the examiner can read and understand your answers, which can affect your overall score.
If you use extra sheets of paper, clearly indicate the question numbers being answered and tie each sheet in your Answer Booklet at the appropriate places. Ensure your Index Number is written on the extra sheets.
The extra 10 minutes allowed for reading the paper gives students time to understand the questions and plan their answers before starting to write.
Using red ink in the Answer Booklet is prohibited as it may not be clearly visible to the examiner and could lead to confusion or misinterpretation of answers.
If you encounter a difficult question, it is recommended to move on to the next question and return to it later if time permits, rather than spending too much time on one question.
