The answer is B. Your going to subtract 4k^2 from both sides, which it would be 4k^2-5k=0. Then you going to factor k(4K-5)=0, which k=0 and 4K-5=0 and then k =0 and 4/5

eimsori [14]

Answer:

When 5 winners are randomly selected, the probability that they are all men is 0.003.

Step-by-step explanation:

Among the contestants in a competition are 46 women and 23 men.

Total persons are =46+23=69

When one winner is chosen, there are 68 people left, when second winner is chosen there are 67 people left and so on.

So, the probability that they are all men is given by:

\frac{23}{69} \times\frac{22}{68} \times\frac{21}{67} \times\frac{20}{66} \times\frac{19}{65}

= \frac{4037880}{1348621560} = 0.002999 ≈ 0.003

Therefore, when 5 winners are randomly selected, the probability that they are all men is 0.003.

kow [346]

Answer:

2 liters of orange juice

Step-by-step explanation:

We know that Gaby drank 3/4 liters of juice

3/4 liters is the same as saying 0.75 liters

3/4 = 0.75

if 0.75 is 3/8 of the container we just have to divide it by 3 and multiply it by 8 and so we will get the liters of the container

(0.75/3) * 8 =

0.25 * 8 =

2

then initially in the container there were 2 liters of orange juice
