Mathematics
1 answer:
olchik [2.2K]3 years ago

Answer:

B

Step-by-step explanation:

Notice that the equation shows KNO_3 going from a solid to an aqueous solution, which is dissolved. Entropy is essentially when a system becomes more disordered. Whenever we go from solid to liquid to gas, that's becoming more disordered because the molecules in the system are moving much more and in more random directions.

In addition, when we dissolve solids into water, that's another increase in entropy because we technically have a liquid component here and the molecules are now breaking apart.

So, the entropy here will increase.

Hope this helps!

One sample has Aa Aa One sample has n 10 scores and a variance of s2 20, and a second sample has n 15 scores and a variance of s
siniylev [52]

Answer:

option (a) It will be closer to 30 than to 20

Step-by-step explanation:

Data provided in the question:

For sample 1:

n₁ = 10

variance, s₁² = 20

For sample 2:

n₂ = 15

variance, s₂² = 30

Now,

The pooled variance is calculated using the formula,

S^{2}_{p} = \frac{(n_{1}-1)\times s^{2}_{1} +(n_{2}-1)\times s^{2}_{2}}{n_{1}+n_{2}-2}

on substituting the given respective values, we get

S^{2}_{p} = \frac{(10-1)\times 20 +(15-1)\times 30}{10+15-2}

or

S^{2}_{p} = 26.0869

Hence,

the pooled variance will be closer to 30 than to 20

Therefore,

The correct answer is option (a) It will be closer to 30 than to 20
