Detailed Summary
DIPLOMA IN DATA MANAGEMENT AND ANALYTICS (DDMA) LEVEL II MATHEMATICAL CONCEPTS IN DATA SCIENCE TUESDAY: 3 December 2024. This paper consists of fifty (50) Multiple Choice Questions. Answer ALL questions by indicating the letter (A, B, C or D) that represents the correct answer. Each question is allocated two (2) marks. If a line has an equation 3y = 3/2x + 9, what are the coordinates of the point where the line intersects with the y-axis. Find the equation of a line with a gradient of 4 and is passing through point (0, -2). Y = 2x - 4 (2 marks) Determine the gradient of a line given by the equation, 5y = -15x + 20. 3 (2 marks) A matrix has 4 columns and 5 rows. What is the order of the matrix. 4x5 (2 marks) A matrix is of order 3 x 3, how many elements does the matrix contain. If A = 5 5 and A-1 = a b , find the value of b. 4 (2 marks) A medical test for a disease is 90% accurate, meaning that the probability of correctly identifying someone with the disease is 0.
Study Tips & Recommendations
Time Management
Practice under timed conditions to improve speed and accuracy. Allocate specific time limits to each section.
Active Practice
