Answer: 0.23
Step-by-step explanation:
Given : F is the event "works in the finishing department;"
and A is the event "is absent excessively."
Given : 10% of all plant employees work in the finishing department; 20% of all plant employees are absent excessively; and 7% of all plant employees work in the finishing department and are absent excessively.
i.e. P(A)= 0.20 ; P(F)=0.10 ; P(A ∩ F) = 0.07
We know that 
Then,
Hence, the required answer is 
Given function : 
Splitting terms to factor it out.
Making it into groups
(5x^3-x^2) + (-5x^2+x) + (-60x+12)
Factoring out GCF of each group.
Factoring x^2-x-12 into (x+3)(x-4)
Applying zero product rule.
5x-1 =0
x+3=0 and
x-4= 0
On solving
x = 1/5 , x=-3 and x=4.
Therefore, zeros of the given function are 
.
