In this experiment randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

In an experiment, variables are carefully controlled in order to ensure the reliability of the results. Usually, treatments are assigned randomly to experimental units. Randomization refers to the assignment of experimental units to groups by chance.

Randomization is important in this experiment because it  tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

Missing parts;

A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

B. Randomization will make up for improper experimental design, data collection, and analysis.

C. Randomization makes the analysis easier since the data can be entered into the computer in any order.

D. Randomization is required by statistical consultants before they will analyze the experiment.

Answer is true

Explanation:

A vector has horizontal and vertical components.

The value of [tex]\mathbf{\theta }[/tex] is 45 degrees, when the horizontal and vertical components are equal

Let the magnitude of the vector be H.

So, the horizontal (h) and the vertical components (v) of the vector would be:

[tex]\mathbf{v = Hcos(\theta)}[/tex] --- vertical

[tex]\mathbf{h = Hsin(\theta)}[/tex]

Equate both expressions

[tex]\mathbf{h = v}[/tex]

Substitute values for h and v

[tex]\mathbf{Hcos(\theta) = Hsin(\theta)}[/tex]

Divide both sides by H

[tex]\mathbf{cos(\theta) = sin(\theta)}[/tex]

When [tex]\mathbf{cos(\theta) = sin(\alpha)}[/tex], then

[tex]\mathbf{\theta + \alpha = 90^o}[/tex]

So, we have:

[tex]\mathbf{\theta + \theta = 90^o}[/tex]

[tex]\mathbf{2\theta = 90^o}[/tex]

Divide both sides by 2

[tex]\mathbf{\theta = 45^o}[/tex]

Hence, the value of [tex]\mathbf{\theta }[/tex] is 45 degrees

The American Civil War, commonly referred to by other names, lasted from April 12, 1861, until May 26, 1865. The Union[f] ("the North") and the Confederacy ("the South"), the latter of which was made up of seceding states, engaged in combat.

The conflict over whether to allow slavery to spread into the western regions, creating more slave states, or to forbid it from doing so, which was widely believed to put slavery on the path to eventual extinction, was the main driver of the war.

The election of Abraham Lincoln as president of the United States in 1860 ended years of political contention over slavery because he opposed its spread into the country's western territories.

The expression that is equivalent to [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹ is;

1/(36a⁴b¹⁰)

[(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹

[(2a⁻³b⁴)² × (3a⁵b)²]⁻¹

Let us simplify (2a⁻³b⁴)² to get;

4b⁸/a⁶

Similarly for (3a⁵b)²;

⇒ 9a¹⁰b²

Thus, we now have;

[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹

Thus; a¹⁰/a⁶ = a⁴

Similarly  b⁸ × b² = b⁽⁸ ⁺ ²⁾ = b¹⁰

[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹ = (36a⁴b¹⁰)⁻¹

Finally, we now have;

(36a⁴b¹⁰)⁻¹ = 1/(36a⁴b¹⁰)

Considering the Hess's Law, the enthalpy change for the reaction is 790 kJ/mol.

Hess's Law indicates that the enthalpy change in a chemical reaction is the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.

In this case you want to calculate the enthalpy change of:

C(s) + 2 SrO(s) → CO₂ (g) + 2 Sr(s)

You know the following reactions, with their corresponding enthalpies:

Equation 1: 2 Sr (s) + O₂ (g) → 2 SrO (s) ∆H° = -1184 kJ/mol

Equation 2: CO₂ (g) → C (s) + O₂ (g) ∆H° = 394 kJ/mol  

In this case, first, to obtain the enthalpy of the desired chemical reaction you need 1 mole of C (s) on reactant side and it is present in second equation. But since this equation has 1 mole of C (s) on the product side, it is necessary to locate this on the reactant side (invert the reaction). And when an equation is inverted, the sign of ΔH also changes.  

Now, 2 moles of SrO (s) must be a reactant and is present in the first equation. Since this equation has 2 moles of Sr0 (s) on the product side, it is necessary to locate the O on the reactant side (invert the reaction) and the sign of ΔH changes.

In summary, you know that two equations with their corresponding enthalpies are:

Equation 1:  2 SrO (s) → 2 Sr (s) + O₂ (g)     ∆H° = 1184 kJ/mol

Equation 2: C (s) + O₂ (g) → CO₂ (g)     ∆H° = -394 kJ/mol

Adding or canceling the reactants and products as appropriate, and adding the enthalpies algebraically, you obtain:

C(s) + 2 SrO(s) → CO₂ (g) + 2 Sr(s)     ΔH= 790 kJ/mol

Finally, the enthalpy change for the reaction is 790 kJ/mol.

Based on the calculations, the magnitude of side DZ is equal to 4 units.

From the diagram, we can deduce that CD is parallel to XZ and as such, triangle XYZ is similar to Triangle YCD. Thus, the ratio of their corresponding side lengths are equal.

By applying the similarity condition, we have:

XY/CY = ZY/YD

(XC + CY)/CY = (DZ + DY)/DY

Substituting the given parameters into the formula, we have;

(5 + 25)/25 = (DZ + 20)/20

30/25 = (DZ + 20)/20

600 = 25DZ + 500

Explanation:

The folktale "The Tiger´s Whisker" originates from Korea, and it is used mostly as a child´s tale. It narrates the story of Yun Ok, whose husband has changed drastically from a loving, and gentle man, to an irrascible one, thanks to the wars. In desperation, Yun Ok, goes to a hermit and asks for a potion. The man tells her that in order to do so, she must bring a whisker from a live tiger. Yun Ok does as she is told, and patiently gains the trust of a tiger, and gets the needed whisker. In the end, she finds out that the lesson the hermit wanted her to learn was that to regain her husband, she needed to apply the same technique she used on the tiger, and not a potion. Given this background, the answers would be thus:

1. A folktale is defined precisely as: A story that is often passed along by word of mouth from one generation to another. This is the correct answer.

2. In this question, the answer is: Her husband has become very distant since he returned from war. This is what is narrated in the story as the reason for Yun Ok´s husband´s estrangement.

3.  The correct answer here is: He laughs at Yun Ok´s idea because he thinks she is foolish to believe that solving the problem with her husband could be so simple. Though not directly stated, the hermit does laugh in a way when he says to Yun Ok that healing her husband with a potion is not like taking care of an ear infection. And he makes her feel somewhat foolish for her request. But she insists and he gives in.

4. The answer to this question is: She decides that reconnecting with her husband is worth the risk. This is stated in the story when Yun, although afraid, still continues persistently to go after the tiger, always keeping in mind that all is for the benefit of herself and her husband.

5. The answer here is: She learns that through patience, she can win her husband´s trust and heart like she earned the trust of the tiger. This is the lesson she learns when the hermit burns the whisker and makes her reflect on how she was able to get it from a wild tiger, saying that a man cannot be fiercer, or more difficult, than a tiger.

6.  The answer here is: She is patient and demonstrates perseverance by spending six long months, slowly getting the tiger to trust her before she plucks out his whisker. This is exactly what she does in the story. She spends every day of those six months, carefully gaining the tiger´s trust, until he allows her near, and then allows her to take his whisker.
