babymother [125]

Answer:

On average, the project takes 4 weeks to complete.

Step-by-step explanation:

We have these following probabilities:

25% probability that the activity takes 2 weeks.

50% probability that the activity takes 4 weeks.

25% probability that the activity takes 6 weeks.

How long does the project now take to complete (on average)

We multiply each duration by it's probability.

0.25*2 + 0.5*4 + 0.25*6 = 4

On average, the project takes 4 weeks to complete.

How do you convert 8.41 g/ml to kg/l ?
Agata [3.3K]

we are asked to convert g/mL to kg/L

1 kg is equivalent to 1000 g

then converting g to kg we have to multiply by 0.001 kg/g

1 L is equivalent to 1000 mL

converting mL to L we have to multiply mL by 0.001 L/ml

we can convert 8.41 g/mL as follows

\frac{8.41g *0.001 kg/g}{1 mL*0.001 L/mL} = 8.41 kg/L

answer is 8.41 kg/L
