A measure computed from the entire population is called a parameter.

The correct answer is an option (d)

We know that a parameter is nothing but a numerical value that describes a certain characteristic of the entire population. It is computed using the population values such as population mean, population variance, etc.

Whereas, a statistic is a numerical value that defines certain characteristic of a sample.

It is computed using the sample values such as the sample mean, sample variance, etc.

A qualitative value or a qualitative data are represented by a name, symbol, or a number code. This data is the data about categorical variables.

And the mean is nothing but the average of a set of values.

In the figure below, the area of the shaded portion is 31.5 m²

Given the figure which consists of a square and a rectangle, we want to find the area of the shaded portion. We proceed as follows.

We notice that the area of the shaded portion is the portion that lies between the two triangles.

So, area of shaded portion A = A" - A' where

Now, Area of larger triangle, A" = 1/2BH where

So, A" = 1/2BH

= 1/2 × 16 m × 7 m

= 8 m × 7 m

= 56 m²

Also, Area of smaller triangle, A' = 1/2bH where

So, A" = 1/2bH

= 1/2 × 7 m × 7 m

= 3.5 m × 7 m

= 24.5 m²

So, area of shaded portion A = A" - A'

= 56 m² - 24.5 m²

= 31.5 m²

So, the area is 31.5 m²

There are 600 different combinations of 2 students that can be chosen from a class of 25, where the order of selection does not matter.

The number of different combinations of 2 students that can be chosen from a class of 25, where the order of selection does not matter, can be calculated using the concept of combinations.

The formula to calculate combinations is:

C(n, r) = n! / (r!(n-r)!)

where n is the total number of students and r is the number of students to be chosen.

In this case, we have 25 students and we want to choose 2 students. Plugging these values into the formula:

C(25, 2) = 25! / (2!(25-2)!)

Simplifying further:

C(25, 2) = 25! / (2! * 23!)

Since 2! equals 2 and 23! equals 23 * 22 * 21 * ... * 2 * 1, many terms in the numerator and denominator will cancel out:

C(25, 2) = (25 * 24) / (2 * 1)

C(25, 2) = 600

In the context of property variance, a variance refers to a legal authorization or exception granted to a property owner by the local governing authority. It allows the property owner to deviate from specific zoning regulations or land-use restrictions that would otherwise apply to their property.

The variance process is used when property owners believe that strict adherence to the existing regulations would cause undue hardship or prevent them from fully utilizing their property in a way that is reasonable and consistent with neighboring properties.

The purpose of property variances is to address unique circumstances or hardships that may exist for a particular property. Property variances typically involve submitting an application to the local zoning board or planning department, attending public hearings, and providing evidence or arguments to support the need for the variance.

The governing authority evaluates the application based on factors such as the impact on neighboring properties, public health and safety, and the intent of the zoning regulations. If approved, the property owner is granted permission to proceed with the proposed deviation from the regulations.

Overall, property variances provide flexibility in land-use regulations, allowing property owners to find reasonable solutions that meet their specific needs while still considering the broader community interests and objectives of zoning regulations.

Step-by-step explanation:

The sections of the parallel roads split by the transversals are in proportion, that is

\(\frac{350}{300}\) = \(\frac{first}{1650}\) ( cross- multiply )

300 first = 577500 ( divide both sides by 300 )

first = 1925 ft

Thus

Elm st → Maple st = 1925 + 350 = 2275 ft → B

Answer:

Step-by-step explanation:

Using the z-distribution, it is found that the data provides convincing evidence that the proportion has increased.

At the null hypotheses, it is tested if the proportion has not increased, that is, the difference of the 2017 proportion and the 2014 proportions is not positive, hence:

\(H_0: p_2 - p_1 \leq 0\)

At the alternative hypothesis, it is tested if the proportion has increased, hence:

\(H_1: p_2 - p_1 > 0\)

For each sample, they are given by:

\(p_1 = 0.197, s_1 = \sqrt{\frac{0.197(0.803)}{61}} = 0.0509\)

\(p_2 = 0.383, s_2 = \sqrt{\frac{0.385(0.615)}{52}} = 0.0675\)

Hence, for the distribution of differences, they are given by:

\(\overline{p} = p_2 - p_1 = 0.383 - 0.197 = 0.186\)

\(s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0509^2 + 0.0675^2} = 0.0845\)

It is given by:

\(z = \frac{\overline{p} - p}{s}\)

In which p = 0 is the value tested at the null hypothesis.

Hence:

\(z = \frac{\overline{p} - p}{s}\)

\(z = \frac{0.186 - 0}{0.0845}\)

z = 2.2

Considering a right-tailed test, as we are testing if the proportion is higher than a value, the critical value at the 0.05 significance level is \(z^{\ast} = 1.645\).

Since the test statistic is greater than the critical value for the left tailed test, the data provides convincing evidence that the proportion has increased.

The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.

The smaller machines weigh 60 pounds

The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.

3. Total distance = Speed * time

                           = 48 * (40/60) = 32 miles

The waist-to-hip ratio for the client would be 0.763, which is considered a healthy ratio for women (less than 0.8) and an average ratio for men (less than 0.9).

To calculate the waist-to-hip ratio (WHR), you simply divide the measurement of your waist circumference by your hip circumference.

WHR = waist circumference / hip circumference

Using the measurements you provided, the calculation would be:

WHR = 29 inches / 38 inches = 0.763

Alternatively, if you prefer to use centimeters:

WHR = 74 cm / 97 cm = 0.763

Therefore, the waist-to-hip ratio for the client would be 0.763, which is considered a healthy ratio for women (less than 0.8) and an average ratio for men (less than 0.9).

The value where the histogram balances when supported at that point is called the mode of the distribution.

The mode of distribution is the value that appears most frequently in the data set. It is often used as a measure of central tendency, along with the mean and median. The mode is especially useful when dealing with categorical or discrete data, where the possible values are limited and well-defined.

For example, the mode of a list of test scores might be the score that occurs most frequently, indicating the most common level of performance. In a histogram, the mode is the value where the distribution is highest, or where the histogram balances when supported at that point.
