II only- the distribution of the sample data.

A sampling distribution is a probability distribution of a statistic generated from more samples taken from a specific population.

The sampling distribution shows how the sample means will vary in repeated samples.

The mean is the most common kind of sampling distribution. This kind concentrates on figuring out the mean average of all sample means, which results in the sampling distribution.

A sampling distribution mean is obtained by adding together the average of each sample and reflecting the characteristics of the entire population.

As the number of samples increases, the standard deviation falls, resulting in a normal frequency distribution or a bell-shaped graph.

Explanation:

Apply Multiplicative Distribution Law:

{x + y =9

{8x + 24y = 120

Reduce the greatest common factor on both sides of the equation.

{x + y = 9

{x + 3y = 15

Subtract the two equations: x + y - (x +3y) = 9 - 15

Remove paranthesis: x + y - x - 3y = 9 - 15

Cancel the unknown variables: y - 3y = 9 - 15

Combine like terms: -2y=9 - 15

Calculate the sum or difference: -2y = -6

Reduce the greatest common factor on both sides of the equation: y =3

Substitute one unknown quantity into the elimination: x + 3 = 9

Rearrange unknown terms to the left side of the equation: x = 9 - 3

Calculate the sum or difference: x = 6

Write the solution set of equations: {x = 6

                                                           {y = 3

A union is the graph of a compound inequality that contains "or," meaning the solution is a solution of either inequality, but not necessarily both. The union represents all values that satisfy at least one of the inequalities in the compound inequality. The solution is shown as the shaded region on the graph that represents the union of the solutions of the individual inequalities.

To determine whether S = {(-4, 7)} is a basis for R2, we need to consider two criteria: linear independence and spanning. Answer : S is not a basis for R2.

Linear Independence: A set of vectors is linearly independent if none of the vectors in the set can be written as a linear combination of the others. In this case, since S only contains one vector (-4, 7), it is not possible to form a linear combination using another vector from S. Therefore, S is linearly independent.

Spanning: A set of vectors spans R2 if every vector in R2 can be expressed as a linear combination of the vectors in the set. In this case, since S only contains one vector (-4, 7), it cannot span R2 because it is not possible to represent every vector in R2 using just one vector.

Therefore, based on the given information, we can conclude that S = {(-4, 7)} is linearly dependent and does not span R2. Hence, S is not a basis for R2.

The temperature of the turkey 45 minutes after being removed from the oven is approximately 138.6°F.

It will take approximately 2.32 hours (or 2 hours and 19 minutes) for the turkey to cool from 185°F to 100°F.

The rate at which the turkey cools can be modeled using Newton's Law of Cooling, which states that the rate of cooling of an object is proportional to the difference between its temperature and the temperature of its surroundings. Using this law, we can write:

dT/dt = -k(T - Ts)

where dT/dt is the rate of change of temperature with respect to time, k is a constant of proportionality, T is the temperature of the turkey at time t, and Ts is the temperature of the surroundings (75°F in this case).

Solving this differential equation gives:

T(t) = Ts + (T0 - Ts)e^(-kt)

where T0 is the initial temperature of the turkey (185°F in this case).

Using the fact that the temperature of the turkey is 145°F half an hour after being removed from the oven, we can solve for k:

145 = 75 + (185 - 75)e^(-k*0.5)

which gives k = 0.0736.

Using this value of k, we can solve for the temperature of the turkey at 45 minutes (or 0.75 hours) after being removed from the oven:

T(0.75) = 75 + (185 - 75)e^(-0.0736*0.75) = 138.6°F.

To find the time it takes for the turkey to cool from 185°F to 100°F, we can solve for t when T(t) = 100:

100 = 75 + (185 - 75)e^(-0.0736*t)

which gives t ≈ 2.32 hours.

Answer:

58.03 ft

Step-by-step explanation:

To solve for the total circumference of circle F, we can create a ratio of section angle measure to circumference. We know that these two attributes of a circle have a linear relationship because the formula for arc length (\(S = 2\pi r \cdot \frac{\theta}{360\°}\)) relies proportionately on the radius and angle measure of the section.

angle measure : circumference

               290°   :   46.75 ft

We can multiply this ratio by \(\frac{360}{290}\) to get the corresponding circumference for a 360° section (which is the entire circle).

\(\frac{360}{290}(290\° : 46.75 \text{ ft})\)

\(= 360\° : \boxed{58.03 \text{ ft}}\)

Therefore, the circumference of circle F is approximately 58.03 ft.

Variability :

P = 1.5 ; Q = 1.5

Step-by-step explanation:

The measure of center we can infer from the box plot is the median, which is the point marked by the vertical line in between the box ;

For Group P:

Median = 2 inches

For Group Q :

Median = 3.5 inches

To infer the variability :

We calculate the interquartile range (IQR) :

IQR = Q3 - Q1

Q3 = Upper quartile (end point of box) ; Q1 = lower quartile (start point of box) in the plot

Locate QI and Q3

Group P:

IQR = Q3 - Q1 = 3 - 1.5 = 1.5

The type of sampling described, where the researchers intentionally select a sample with 50% straight and 50% LGBTQ+ respondents, is known as "disproportionate stratified sampling."

A. Disproportionate stratified sampling involves dividing the population into different groups (strata) based on certain characteristics and then intentionally selecting a different proportion of individuals from each group. In this case, the researchers are dividing the population based on sexual orientation (straight and LGBTQ+) and selecting an equal proportion from each group.

B. Availability sampling (also known as convenience sampling) refers to selecting individuals who are readily available or convenient for the researcher. This type of sampling does not guarantee representative or unbiased results and may introduce bias into the study.

C. Snowball sampling involves starting with a small number of participants who meet certain criteria and then asking them to refer other potential participants who also meet the criteria. This sampling method is often used when the target population is difficult to reach or identify, such as in hidden or marginalized communities.

D. Simple random sampling involves randomly selecting individuals from the population without any specific stratification or deliberate imbalance. Each individual in the population has an equal chance of being selected.

while the presence of only one spot on a TLC plate may suggest that the compound is pure, further analysis is needed to confirm the purity of the compound, such as melting point determination, NMR spectroscopy, or HPLC (high-performance liquid chromatography).

Using UV and seeing only one spot on a TLC (thin-layer chromatography) plate is not a definitive indicator of the purity of a product.

While it is true that a pure compound will only show one spot on a TLC plate, there are several reasons why a compound may still show only one spot even if it is not pure. For example:

The impurity may have a similar Rf (retention factor) value to the compound of interest and therefore co-migrate with it on the TLC plate, making it difficult to distinguish between the two.

The impurity may be present in such a small amount that it is not visible on the TLC plate.

The compound of interest may have multiple conformers or isomers that have the same Rf value and appear as a single spot.

The value of the given expression [\(87^3+ 13^3/87^2 -87 * 13 + 13^2\)] by simplifying the numerator and denominator using suitable identities is 100.

We will first calculate the numerator:

As  (\(a^3\) + \(b^3\)) = (a + b)(\(a^2\) - ab + \(b^2\)) :

\(87^3\) + \(13^3\) = (87 + 13)(\(87^2\) - \(87 * 13\) + \(13^2\))

= 100(\(87^2\) - 87 * 13 + \(13^2\))

Now, calculate the denominator:

\(87^2 - 87 * 13 + 13^2\)

As,(\(a^2 -2ab +b^2\)) =\((a - b)^2\):

\(87^2 - 87 * 13 + 13^2 = (87 - 13)^2\)

\(= 74^2\)

So by solving the equation further:

\((87^3+13^3) / (87^2- 87 * 13+13^2) = 100*(87^2- 87 *13 + 13^2)/(87^2 - 87 * 13 + 13^2)\)

As we can see the numerator and denominator are the same expressions (\(87^2 - 87 * 13 + 13^2\)). so, they cancel each other:

\((87^3 + 13^3) / (87^2 - 87 * 13 + 13^2) = 100\)

In the first question, the statement "Using logarithmic differentiation we obtain that the derivative of the function y = x² satisfies the equation y = 4x log x + 2x" is true.

In the first question, using logarithmic differentiation on the function y = x², we differentiate both sides, apply the product rule and logarithmic differentiation, and simplify to obtain the equation y = 4x log x + 2x, which is correct.

In the second question, the statement is false. When using logarithmic differentiation on the function y = (1+x²)²(1 + sin x)²/(1-x²), the derivative is calculated correctly, but the equation given is incorrect. The correct equation after logarithmic differentiation should be y' = (4x/(1 + x²)(1 + sin x))(1-x²) - (2x(1+x²)²(1 + sin x)²)/(1-x²)².

The non-permissible values of B for the trigonometric expression cscx/cosx - 1 are: π/2 + πk for k ∈ Z.

Trigonometric functions, also known as circular functions, are functions of an angle that relate ratios of different sides of a right triangle.

There are six main trigonometric functions: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Non-permissible values are the values of the variables that result in a denominator of zero or an even-indexed root of a negative number.

The reason behind this is that division by zero or an even-indexed root of a negative number is not defined mathematically, resulting in an error in the function.

The given expression is:

cscx/cosx - 1

We can re-write this expression as:

cscx / (cosx - 1)

To find the non-permissible values of B for the trigonometric expression cscx/cosx - 1,

we need to find the values of x that make the denominator (cosx - 1) zero.

Therefore, cosx - 1 = 0cosx = 1x = 2πk for k ∈ Z

This means that the denominator is equal to zero when x = 2πk for k ∈ Z.

These are the non-permissible values for the expression.

We have to exclude these values from the domain of the function to avoid division by zero.

Therefore, the non-permissible values of B are π/2 + πk for k ∈ Z.
