Therefore, the probability that fewer than 3 of them is 0.1111
Answer:
0 and 1
Step-by-step explanation:
x² = 3
take the square root of both sides
x = {-√3, √3}
x ≈ {-1.73, 1.75}
Two consecutive integers between 1.73 and 1.75
0 and 1
Answer:
1r
Step-by-step explanation:
(5r-4)(2r-6r+4)
1(5r-4)+1(2r-6r+4)
5r-4+2r-6r+4
5r+2r-6=1r
1r-4+4
-4+4=0
1r
