Study Notes
Mathematics Review for Grade 10
Sequences and Series
- Identify the next number in the sequence 7, 15, 24, 34, ___: A. 43, B. 44, C. 45, D. 46
- Formula for permutation of non-distinct objects: P(n, r) = n! / (n-r)!
- Arithmetic mean of 3 and 15: A. 10, B. 9
Probability
- Sample space: all possible outcomes of an experiment
- Event: a set of outcomes of an experiment
- Probability of an event: number of favorable outcomes / total number of possible outcomes
Circles
- Center and radius of a circle: C (0, 0); r = 4, or C (1, 1); r = 4
- Equation of a circle: (x - 5)² + (y - 0)² = 25
- Area of a circle: πr²
Combinatorics
- Permutation: arrangement of objects in a specific order
- Combination: selection of objects without regard to order
- Formula for permutation: P(n, r) = n! / (n-r)!
- Formula for combination: C(n, r) = n! / (r!(n-r)!)
- Example: number of ways to choose 6 individuals from 15 players: A. 5, 005, B. 12, 376, C. 3, 603, 600, D. 8, 910, 700
Polynomials
- Factoring polynomials: finding the linear factors of a quadratic expression
- Example: x² + 5x - 6 = (x + 6)(x - 1)
Geometry
- Semicircle arch: diameter = 4 meters, length of iron before bending = π meters
- Circle inside a square: radius = 4 inches, area = 16π sq.in.
Sets
- Union of sets: all elements in either set A or set B
- Intersection of sets: all elements common to both sets A and B
- Example: A = {1, 2, 3, 4}, B = {4, 5, 6, 7}, A ∪ B = {1, 2, 3, 4, 5, 6, 7}, A ∩ B = {4}
