Answer:
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.
Answer: Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.
Step-by-step explanation:
Since we have given that
Number of crashes due to pilot error = 699
Number of crashes due to other human error = 88
Number of crashes due to mechanical problems = 156
Number of crashes due to sabotage = 164
Total number of crashes = 699+88+156+164 = 1167
So, Relative frequency distribution :
Pilot error =
Human error =
Mechanical problems =
Sabtoge =
Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.
