a) A is better for the better experiment. A creates similar with respect to forest exposure. This are because of the orthogonal effect in quadratic main model.

b) Randomization of variety of trees to plot within each block reduces any bias due to comforting variable.

Blocking Scheme:

In this subsection, the goal is to construct a blocking design such that the blocking effects are orthogonal to the terms in the linear main effects model so that a linear plus quadratic main effects model can be estimated. Assume that all m-factors are quantitative and an m0-factor DSD is constructed. where m0 = m + k and n = 2(m + k) + 1 runs.  Removing the intermediate run from  results in a 2(m + k) run design.

Randomization:

When you randomize an experiment, you select subjects at random. For example, you can use simple random sampling. In this case, participant names are randomly drawn from a pool with each having an equal probability of being selected. You can also randomly assign treatments to participants by assigning random numbers from a random number table.

If you use randomization in your experiments, protect yourself from bias. For example, selection bias (where some groups are underrepresented) is eliminated and accidental bias (where random imbalance occurs) is minimized. If your sample is random, you can also run various statistical tests on the data (to test hypotheses).

the measure of the value a is 24°

What is are of triangle?

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.

The sum of all angles of triangle = 180

Here given 3 angles are 2a, 3a and a+36°

So the sum of all the angles should be 180°

⇒2a+ 3a +a+36° = 180

⇒6a = 180-36

⇒a = 144/6= 24

Hence the measure of the value a is 24°

The descending order of the multiplied polynomial is 4x² - 3x + 8xy - 6y

The word polynomial in math refers the algebraic expression in which the exponents of all variables should be a whole number.

Here we have given the polynomial l (x + 2y)(4x - 3).

And we need to do the multiplication operation on it and then write your answer in descending order of x.

AS per the following formula, the multiplication of the polynomial is calculated as,

Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment.

The correct option is: A

Statement I is the cause and statement II is the effects.

Since the Government has imported large quantities of sugar as per trade agreement with other countries, the prices of sugar in the domestic market have fallen sharply in the recent months.

The reason behind this statement is:

An increase in supply always leads to a decrease in price.

Supply : Supply is a fundamental economic concept that describes the total amount of a particular good or service available to consumers. Supply can refer to the quantity available at a particular price or the quantity available across the price range displayed on the chart. It is closely related to the demand for goods or services at a particular price. All else being equal, when prices rise, producer supply increases as all firms try to maximize their profits.

Increase in Supply:

If the demand does not change, there is an inverse relationship between the supply and price of goods and services. When the supply of goods and services increases at the same demand, prices tend to fall resulting in lower equilibrium prices and higher equilibrium quantities of goods and services. When the supply of goods and services decreases for the same demand, prices tend to rise towards higher equilibrium prices and smaller quantities of goods and services.

Since the supply of sugar increases as government has over imported, the price of sugar decreases in domestic market.

Given as that unknown mean and a known variance.

let's suppose parameter for mean as µ and

Confidence means what degree of assurance do we desire that the interval estimate contains the  populace mean µ.

The population parameter is contained in estimate.

If the level of confidence is 90%, this means that we are 90%

confident that the interval contains the population mean, µ

The corresponding z-scores for 90% confidence interval are ± 1.645.

If the level of confidence is 95%, this means that we are 95%

confident that the interval contains the population mean, µ

The corresponding z-scores for 95% confidence interval are ± 1.96.

So In comparison to a 95% Confidence Interval, a 90% Confidence Interval would be narrower. This happens because the reliability of an interval containing the actual mean declines as the confidence interval's precision rises (i.e., CI width decreases) (less of a range to possibly cover the mean). Consider the case of 100% confidence; the interval must contain all possible values in order to guarantee that the mean is captured with 100% certainty.

What is an isosceles trapezoid?

An isosceles trapezoid is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal.

In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram). The diagonals are also of equal length.

The diagonals are congruent because if the diagonals are congruent the at least to of its legs (probably the vertical ones) are congruent. and the median is parallel to the bases in isosceles trapezoid  because parallelism indicates that heights (vertical legs) are accurately congruent .

We want to see for which one of the given functions, the inverse derivate evaluated in x = 20 is equal to 1/5.

The correct option is B:  f(x) = x^3 + 5x + 20

What is inverse derivative?

The inverse function rule in calculus is a formula that converts the derivative of the inverse of a bijective and differentiable function, f, into the derivative of f.

Remember that two functions f(x) and g(x) are inverses if:

f( g(x)) = g( f(x))) = x

And for the inverse derivate of a function, we have the rule:

[tex]\frac{d}{dx}[f^{-1} (f(x))]=\frac{1}{{f^'}(x)}[/tex]

So first we need to find for what value of x each function is equal to 20, and then we need to see if the derivate of the function evaluated in that same value of x is equal to 5.

For example, for the first option we have:

A: f(x) = x + 5

We find the x-value such that the function is equal to 20.

f(15) = 15 + 5 = 20

We derivate the function.

f'(x) = 1

We evaluate the function in the x-value we got above.

f'(15) = 1

This is not the correct option, as this is not 5.

Now we need to do that for all the given options.

The only correct option will be the second one:

B: f(x) = x^3 + 5x + 20

First we find the x-value such that this is equal to 20

f(0) = 0^3 + 5*0 + 20 = 20

Then the x-value is x = 0.

Now we find the derivate of f(x).

f'(x) = 3*x^2 + 5

Now we evaluate that in the x-value we got before:

f'(0) = 3*0^2 + 5 = 5

As wanted, this is equal to 5.

Then we have:

[tex]\frac{d}{dx}[f^{-1} (f(0))]=\frac{1}{{f^'}(0)}[/tex]
