This week in maths we have been looking at patterns made with matches. We looked at the first term, the second term, … the tenth term, … and so on and tried to find a relation between the number of matches and the number of the term. For example, we explored this pattern with matches: an se lit « a puissance n » ou « a exposant n ». Exemples : 25 = 2 × 2 × 2 × 2 × 2 = 32. 2 0001 = 2 000. (-3)2 ...Q is the set of rational numbers, ie. represented by a fraction a/b with a belonging to Z and b belonging to Z * (excluding division by 0). Example: 1/3, -4/1, 17/34, 1/123456789 ∈Q ∈ Q. The set Q is included in sets R and C. Sets N, Z and D are included in the set Q (because all these numbers can be written in fraction). The set of integers symbol (ℤ) is used in math to denote the set of integers. The symbol appears as the Latin Capital Letter Z symbol presented in a double- ...Solution: The z score for the given data is, z= (85-70)/12=1.25. From the z score table, the fraction of the data within this score is 0.8944. This means 89.44 % of the students are within the test scores of 85 and hence the percentage of students who are above the test scores of 85 = (100-89.44)% = 10.56 %. A constant in math is a fixed value. It may be a number on its own or a letter that stands for a fixed number in an equation. For example, in the equation “6x – 4 = 8,” both 4 and 8 are constants because their values are fixed.−4 est un nombre entier négatif, c'est donc un nombre entier relatif.
