Quiz

Answer/Solution

Five

Steps/Work

The inequality given is 1 < 3x+5 < 17
it can further reduced to -4 < 3x < 12
finally -4/3 < x < 4
So can only take 5 integer values i.e. -1,0,1,2,3

Calculated Answer

5

Step by Step Solution

In order to solve problem, you must evaluate floor((n3 - n2) / n1 - (n0 - n2) / n1).

n0 =1
n1 =3
n2 =5
n3 =17
