Using evidence from the text and background information, how does the author's point of view match up to Buck's point of view?

Consider a sample with data values of 27, 25, 20, 15, 30, 34, 28, and 25. Compute the 20th, 25th,65th , and 75th percentiles

Kay [80]

Answer:

Percentile of 20th = 20

Percentile of 25th = 22.5

Percentile of 65th = 28

Percentile of 75th = 29

Explanation:

Sort the numbers in ascending order:

15,20,25,25,27,28,30,34

i = P/100 * N ( i index is the position of the number. Index 1 = 15, index 2 = 20, and so on)

Index of the 20th percentile:

20/100 * 8 = 1.6

Round 1.6 to the next integer = 2

The second number I=20

The 20th percentile is 20

Index of the 25th percentile:

25/100 * 8 = 2

Because 2 is an integer the percentile of 25th is the average of I=20 and I=25

(20+25)/2=22.5

The 25th percentile is 22.5

Index of the 65th percentile

i = 65/100 * 8 = 26.5 = 5.2

Round to the next integer = 6

The 65th percentile is 28

Index of the 75th percentile

I = 75/100 * 8 = 6

Since 6 is an integer (28+30)/2 = 29 percentile

An unsaturated solution is formed when 80. Grams of a salt is dissolved in 100. Grams of water at 40. °c. This salt could be.

Alinara [238K]

${answer}$

An unsaturated solution is formed when 80. Grams of a salt is dissolved in 100. Grams of water at 40. °c. This salt could be.

Solubility is the maximum amount of soluble solid that can be dissolved in a 100-gram of water at a specific temperature. The solubility of a compound is directly proportional to the temperature which means that more solids can be dissolved at a higher temperature. Moreover, a solution which has a concentration below its solubility is an unsaturated solution. When both concentration and solubility are the same, then the solution is saturated. Lastly, when the concentration of a solution is higher than the solubility at a specific temperature, then the solution is called supersaturated.

At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has.

vovangra [49]

Bromine has stronger inter molecular force than Fluorine.

<h3> Inter molecular forces and relationship with physical states of matter</h3>

The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.

For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.

For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.

For gases, the the inter molecular forces are weakest as the molecules move about.

We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.

In the middle of our sleep a burglar broke in our house.

jek_recluse [69]

The question requires that we identify the past continuous form of the sentence. The answer to the question will be:

When we were in the middle of our sleep, a burglar broke into our house.

The past continuous form of a sentence describes an action that started sometime in the past and continued for a while after it began.

The sentence above describes a past continuous sentence because it described an action that was ongoing sometime in the past.
