Answer:

  k = 9/8

Step-by-step explanation:

For a root with multiplicity 2, the discriminant must be zero. For quadratic ax^2 +bx +c, the discriminant is ...

  d = b^2 -4ac

For your quadratic, a=2, b=3, c=k, so you want ...

  3^2 -4(2)(k) = 0

  9 -8k = 0

  k = 9/8

A coin is flipped twice. What is the probability that the coin will land on tails on the first flip and will land on tails again
bixtya [17]

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

1/4=25

0.25 x 100= 25%

hope that helps
