Answer:

k = - 12.56 or k = 0.56

Step-by-step explanation:

Given

k² + 12k = 7

To complete the square

add ( half the coefficient of the k- term )² to both sides

k² + 2(6)k + 36 = 7 + 36, that is

(k + 6)² = 43 ( take the square root of both sides )

k + 6 = ± \sqrt{43} ( subtract 6 from both sides )

k = - 6 ± \sqrt{43}, thus

k = - 6 - \sqrt{43} ≈ - 12.56 or k = - 6 + \sqrt{43} ≈ 0.56

for events A and B, P(A)= 3/14 and P(B)= 1/5. Also, P(A and B)= 3/65. Are A and B independent events?
Lady_Fox [76]

No, A and B are not independent events

Step-by-step explanation:

Let us study the meaning independent probability  

  • Two events are independent if the result of the second event is not  affected by the result of the first event
  • If A and B are independent events, the probability of both events  is the product of the probabilities of the both events  P (A and B) = P(A) · P(B)

∵ P(A) = \frac{3}{14}

∵ P(B) = \frac{1}{5}

∴ P(A) . P(B) = \frac{3}{14} × \frac{1}{5}

∴ P(A) . P(B) = \frac{3(1)}{14(5)}

∴ P(A) . P(B) = \frac{3}{70}

∵ P(A and B) = \frac{3}{65}

∵ P(A) . P(B) = \frac{3}{70}

- The two answers are not equal

∴ P (A and B) ≠ P(A) · P(B)

- In independent events P (A and B) = P(A) · P(B)

∴ A and B are not independent events

No, A and B are not independent events
