La méthode d'Al Khwarizmi Au ixe siècle, le mathéma-
ticien arabe Al Khwarizmi
(dont le nom est à l'origine
du mot « algorithme ») a
utilisé une méthode géo-
métrique pour trouver
une solution de l'équation
x²+10x = 39.
On construit un carré de
côté x.
On borde ce carré de deux
rectangles dont l'aire est
10x/2
On complète le grand carré.
L'ensemble a pour aire x² +10x + 25, soit 39 + 25 = 64.
Ainsi, le grand carré a pour côté 8.
x vaut donc 3.
1. À l'aide de la méthode d'Al Khawarizmi, résoudre
l'équation x² + 12x = 85.
2. Faire de même avec l'équation x² + 2x = 8.

Which ratios are equivalent to 10: 16? check all that apply. 30 to 48 25: 35 8: 32 5 to 15

Question 10 of 211 pointuse the elimination method to solve the system of equations. choose thecorrect ordered pair.10x +2y = 643x - 4y = -36a. (4,12)b. (-3, 11)c. (2,10)d. (-5, 8)

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
