Answer:
There are two rational roots for f(x)
Step-by-step explanation:
We are given a function
To find the number of rational roots for f(x).
Let us use remainder theorem that when
f(a) =0, (x-a) is a factor of f(x) or x=a is one solution.
Substitute 1 for x
f(1) = 1-2-5+6=0
Hence x=1 is one solution.
Let us try x=-1
f(-1) = 1-2-5+6 =0
So x =-1 is also a solution and x+1 is a factor
We can write f(x) by trial and error as
We find that 
factor gives two irrational solutions as
±√3.
Hence number of rational roots are 2.
Answer:
a) 0.8
b) 0.3
c) 0.9
d) 0.95
Step-by-step explanation:
A probability always adds up to 1. It is between the scale of 0 (never likely) to 1 (very likely).
So:
1 - 0.2 = 0.8
1 - 0.7 = 0.3
1 - 0.1 = 0.9
1 - 0.05 = 0.95
