Answer:
Step-by-step explanation:
given,
straight stick of length = 2, 3, 5, 7, 11, and 13.
For a triangle to form third side of the sum of the two side of the triangle should be greater than third.
so the possibility of triangle formed
5,11,13
7,11,13
3,11,13
7,5,11
5,3,7

⁶C₃ = = 20
so the probability =
=
Percent increase from 2000 to 2001 is 12% and from 2001 to 2002 is 12.6%. Thus period of 2001 to 2002 has higher increase percentage.
Solution:
Given that,
Total circulation of local newspaper in 2000 = 3250
Total circulation of local newspaper in 2001 = 3640
Total circulation of local newspaper in 2002 = 4100
As we can see 12% < 12.6%
So period of 2001 to 2002 has higher increase percentage.
A multiplication is zero if and only if at least one of the factors is zero. So, in this case, the multipications equals zero when
The first equation has no real solutions, because is a square, and thus it's positive. If you add 4 to a positive number, the result can't be zero.
The second equation has the solution
So, globally, the expression equals zero if and only if
