[ - 9 + ( - 3 ) × ( - 2 ) ] + 4 = [ - 9 + 6 ] + 4 = [ - 3 ] + 4 = 1
17 % de 500 = 17/100 × 500 = 0,17 × 500 = 85
Médiane = 85
AM/AB = MN/BC AM/200 = 80/100 AM = 160
AB² = 80² + 60² = 6400 + 3600 = 10000 donc AB = √10000 = 100

M = [190+160+210+140+170+200+150+220]/8 = 180
3 ( x - 6 ) = 6
3x - 18 = 6
3x = 24
x = 24/3 = 8
