This is an example of what type of sampling?This is an example of Stratified probability sampling.What is stratified probability sampling?Stratified sampling is a type of probability sampling that divides the population into subgroups or strata based on relevant characteristics. The strata are then randomly chosen, and samples are obtained from within each stratum.

Stratified sampling may be useful in situations where researchers want to obtain a representative sample of a population while simultaneously ensuring that the sample is sufficiently representative of different subgroups within the population. It might be used, for example, in a study of people's attitudes about social media, with strata based on age or socioeconomic status.Stratified sampling, like all probability sampling methods, has the advantage of ensuring that the sample is representative of the population from which it was drawn. Because samples are drawn at random, the conclusions based on them can be generalised to the population as a whole.

We can see that the units in which x₁ and x₂ are measured will have no effect on the estimated coefficient B₁. However, it will have an effect on the coefficient B₂, as seen above.

Consider the following model: Y_1 =B_1 x_1 + B_2 x_1^2 + U_1, i=1,2,...,n Given that we have to change the units in which both x₁ and x₂ are measured in such a way that our new model becomes:$$y_1 = B_1$$It can be concluded that the variables x₁ and x₂

will have new measurements in this scenario. Hence, the conversion formula for x₁ and x₂ will be as follows: x_{1(new)}= ax_1 \quad \text{and} \quad x_{2(new)} = bx_2where "a" and "b" are constants. Substituting these new measurements into the original equation, we get:Y_1 =B_1(ax_1) + B_2(ax_1)^2 + U_1\implies Y_1= (a^2B_2)x_1^2 + (aB_1)x_1 + U_1Now, by comparing the new and original model equations, we get:B_1= aB_1 \implies a=1B_2 = a^2B_2 \implies a= \pm 1.

Thus, we can see that the units in which x₁ and x₂ are measured will have no effect on the estimated coefficient B₁. However, it will have an effect on the coefficient B₂, as seen above.

2x² + 8x - 1 = 0

2(x + 2)² - 9 = 0

2(x + 2)² = 9

Answer:

469.4ft²

Step-by-step explanation:

We have ∆ WXY in the above question,

From which we have obtained the following values

Angle W = 27°

Angle X = ?

Angle Y = 40°

Side w =?

Side x = ?

Side y = 38ft

Area of the triangle= ?

Step 1

We find Angle X

We know that the Sum of angles in a triangle = 180°

In the question above, we are given 2 angles

Hence,

Angle X = 180 - ( Angle W + Angle Y)

= 180° - (27 + 40)°

= 180° - 67°

Angle X = 113°

Step 2

Find the sides w and x

We find these sides using the Rule of sines

Rule of Sines =

a/ sin A = b/ Sin B = c/Sin C

Hence for triangle WXY

w/ sin W = x/ sin X = y/ sin Y

We have the following values

Angle W = 27°

Angle X = 113°

Angle Y = 40°

We are given side y = 38ft

Determining side w

w/ sin W= y/ sin Y

w/sin 27 = 38/sin 40

Cross Multiply

sin 27 × 38 = w × sin 40

w = sin 27 × 38/sin 40

w = 26.83879ft

w = 26.84ft

Determining side x

w/ sin W = x/ sin X

26.84/ sin 27 = x/sin 113

Cross Multiply

sin 113 × 26.84 = x × sin 27

x = sin 113 × 26.84/sin 27

x = 54.42041ft

x = 54.42ft

To find the area of triangle WXY

We apply the use of heron formula

= √s(s - w) (s - x) (s - y)

Where S = w + x + y/ 2

s = (38 + 26.84 + 54.42)/2

s = 59.63

Area of the triangle = √59.63× (59.63 - 38) × (59.63 - 26.84 ) × (59.63 - 54.42)

Area of the triangle = √ 220343.61423

Area of the triangle = 469.40772706541ft²

Answer:

80/45 or 1 35/45 simplifed to to 1 7/9

Step-by-step explanation:

do 8/15 times 10/3

8 times 10 is 80

15 times 3 is 45

so 80/45 then make into mixed number

Answer:

\(1\frac{7}{9}\)

Step-by-step explanation:

\(\frac{5}{15} *3 \frac{1}{3} \\\)

Turn the second part into an improper fraction by multiplying the coefficient (the big 3) by the denominator of the fraction. You should get 3*3 = 9. Then add that number to the numerator of the fraction to get this:

\(\frac{8}{15} * \frac{10}{3}\)

Now, multiply directly across, so 8*10 over 15*3.

\(\frac{8*10}{15*3}\) Now multiply out:  \(\frac{80}{45}\)

You can simplify this into \(\frac{16}{9}\)

Now, see how many times the denominator goes into the numerator evenly (1 time) and subtract that from the numerator to get \(1\frac{7}{9}\)

Answer:

33 square units

Step-by-step explanation:

Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.

The area of a rectangle is simply \(A = bh\), where b represents the base and h represents the height.

Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.

Substituting in the values, we get:

\(A = (6)(4)\\A = 24\)

The area of the rectangle is 24 square units

The area of a triangle is simply \(A = \frac{1}{2} bh\).

The base of each triangle is 3, and the height of each triangle is also 3.

Substituting in the values, we get:

\(A = \frac{1}{2} (3)(3)\\A = \frac{1}{2} (9)\\A = 9 / 2\\A = 4.5\)

The area of each triangle is 4.5 square units

To get the area of the polygon, we simply add up the area of the rectangle and both triangles

\(A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33\)

The total area of the polygon is 33 square units.

The level of measurement for the data collected in the study (the average weight of newborn babies in ounces) is interval.

\

Interval data is a type of quantitative data, meaning it can be measured numerically and is used when the order or magnitude of the data is important. Unlike ordinal data, the difference between two values is the same regardless of where it falls in the scale.

For example, if two newborn babies weighed 5 and 10 ounces respectively, the difference between the two is 5 ounces. This 5-ounce difference would be the same no matter what order the babies were in. This is an example of interval data.

Another example of interval data would be temperature. When comparing temperatures, the difference between 60 and 70 degrees is the same as the difference between 70 and 80 degrees.

Interval data can be graphed on a line graph. It can also be used in calculations, such as the mean and standard deviation, as the data is numerical and can be averaged.

To summarise, the data collected in the study (the average weight of newborn babies in ounces) is interval data as it is numerical and the difference between two values is the same regardless of where it falls in the scale.

The width of the foil = w = 2.5 inches

Step-by-step explanation:

We know that the Area of a rectangular piece:

\(A=wl\)

Here:

Given that area of the rectangular piece of foil:

Area = A = 11 1/4 square inches

               = 45/4 square inches

               = 11.25 square inches  

Length = l = 4 1/2 inches

                 = 9/2 inches

                 = 4.5 inches

Using the Area formula

\(A=wl\)

\(w\:=\:\frac{A}{l}\)

    \(=\frac{11.25}{4.5}\)

Analysts use financial ratios rather than absolute numbers because ratios provide a more meaningful and comparative assessment of a company's financial performance.

Ratios allow for a standardized comparison between companies of different sizes and industries, facilitating a better understanding of their financial health, operational efficiency, and profitability.

Furthermore, ratios enable analysts to evaluate a company's performance over time and benchmark it against industry averages and competitors. Some examples of commonly used financial ratios include the current ratio, return on equity (ROE), and earnings per share (EPS).

Current Ratio: The current ratio measures a company's ability to meet its short-term obligations. It is calculated by dividing current assets by current liabilities. For example, if a company has current assets of $500,000 and current liabilities of $250,000, the current ratio would be 2 ($500,000 / $250,000). A higher current ratio indicates a stronger liquidity position, suggesting the company is better equipped to meet its short-term financial obligations.

Return on Equity (ROE): ROE measures a company's profitability relative to its shareholders' equity. It is calculated by dividing net income by average shareholders' equity and multiplying by 100 to express it as a percentage. For instance, if a company has a net income of $1 million and average shareholders' equity of $10 million, the ROE would be 10% ($1 million / $10 million * 100). A higher ROE signifies better profitability and efficient utilization of shareholders' capital.

Earnings per Share (EPS): EPS indicates the profitability of a company on a per-share basis. It is calculated by dividing net income attributable to common shareholders by the weighted average number of outstanding shares. For example, if a company has a net income of $5 million and 10 million weighted average shares outstanding, the EPS would be $0.50 ($5 million / 10 million). A higher EPS implies higher profitability for each share held by investors.

Financial ratios provide valuable insights into a company's financial performance and facilitate better comparisons and analysis. Absolute numbers alone may not convey the same level of meaningful information or allow for easy comparisons between companies. Ratios allow analysts to assess a company's financial health, profitability, liquidity, efficiency, and other key aspects relative to industry peers and historical performance.

They help identify trends, strengths, weaknesses, and potential investment opportunities or risks. While absolute numbers provide essential context, ratios offer a standardized framework for evaluation and decision-making, making them a preferred tool for financial analysis.
