Choose the set of measurements listed in order from greatest to least. A. 20 kl, 20 L, 20 ml B. 20 L, 20 ml, 20 kl C. 20 ml, 20

Alex17521 [72]

Answer: A

Step-by-step explanation:

First, we know that each set has 20 kL, 20 L, and 20 ml. To know if they are in the order from greatest to least, we should make sure all three have the same units. Once we do, we can put them in order.

20 kL=20000 L

20 mL=0.02 L

20 L=20L

Now that we have made sure the units are all the same, we know that 20 kL is the greatest and 20 mL is the smallest. The final order is 20 kL, 20 L, 20 mL.

leonid [27]

<h2>Answer with explanation:</h2>

Given : The critical path for the project has an expected duration of 112 days, and a standard deviation of 5 days.

i.e. $\mu=112\ ;\ \sigma=5$

We assume that this a normal distribution.

Let x be the random variable that represents the time duration to complete the project.

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x= 115

$z=\dfrac{115-112}{5}=0.6$

P-value : $P(z$

Thus, the probability of finishing on time if the due date is 115 days is 0.726.

Also, for x= 120

$z=\dfrac{120-112}{5}=1.6$

P-value : $P(z>120)=P(z>1.6)=1-P(z$

$1-0.9452007=0.0547993\approx0.055$

Hence, the probability that they will have to pay the penalty is 0.055 .

What properrty is shown? 4+(3+2)=4+(2+3)

BabaBlast [244]

The commutative property is shown. It states that an equation has the same value as it would even if the numbers were mixed. In this equation, the 2 and the 3 are switched within the parentheses, so it still has the same value.
