Answer:
25
Step-by-step explanation:
Root 5 has multiplicity of 2. root -3 as multp of 1
y = (x-5)^2(x+3)
expand to get y = x^3 - 7x^2 - 5x + 75
For the sequence of events, the probability of being assigned 012 is:
P(012)=(1/4)(1/10)(1/10)
P(012)=1/400 (0.25%)
X^2-81=0
x^2-81+81=0+81
x^2=81
sqrt(x^2)=+-sqrt(81)
x=+-9
x=-9 and x=9
Answer: Options D. -9 and E. 9
