Answer:
Step-by-step explanation:
Given Probability that bid will be unsuccessful = 0.35
a) What is the prior probability that the bid will be successful ;
= 1 - P(unsuccessful) = 1 - 0.35
= 0.65
b) What is the conditional probability of a request for additional information given that the bid will ultimately be successful = 0.70
c) Compute the posterior probability that the bid will be successful given a request for additional information ; Applying Baye's theorem ;
P(S|AI) = P(S) X P(AI|S) / P(S) X P(AI|S) + P(Unsuccessful) x P(AI|S)
= 0.65 X 0.70 / 0.65 X 0.70 + 0.35 X 0.35
= 0.6125
The answer for this is 140.
Answer:
B is true
Step-by-step explanation:
given f(x) = 2x² - x - 1 and g(x) = x - 1
A
If x = - 1 is a root then f(- 1) = 0
f(- 1) = 2(- 1)² - (- 1) - 1 = 2 + 1 - 1 = 2 ≠ 0 ← False
B
If (x - 1) is a factor then x = 1 is a root and f(1) = 0
f(1) = 2(1)² - 1 - 1 = 2 - 1 - 1 = 0
⇒ g(x) = x - 1 is a factor of f(x) ← True
C
If x = 2 is a root then f(2) = 0
f(2) = 2(2)² - 2 - 1 = 8 - 3 = 5 ≠ 0 ← False
D
= 
Cancel the factor (x - 1) on the numerator/ denominator, leaving
= 2x + 1 with remainder 0 ≠ 2 ← False
