A class of 26 boys were each required to have certain textbooks in English, French and Mathematics.19 boys had the English book,23 had the French book and 15 the Mathematics book.16 boys had both the English and French books,14 had the French and Mathematics books and 13 had the Mathematics and English books. i. how many boys in the class have all 3 books,
ii. two books only,
iii. English and French books but not Mathematics,
iv. only french books,
v. only one book.
vi. What is the probability that a boy in the class has all 3 books, if chosen at random​

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

a)(x-2)^2+(y-1)^2=9
