In this example, the group of 20 people surveyed was the study's sample.

The researcher conducted a longitudinal study, tracking the social adjustment of the same group of 20 individuals from early childhood to adulthood. By using the same group over an extended period, the researcher aimed to observe and analyze the changes in social adjustment within this specific sample.

A sample refers to a subset of individuals or elements taken from a larger population for the purpose of conducting research or drawing conclusions. In this case, the 20 people surveyed represent the sample on which the study focused. The researcher likely chose this group carefully to ensure it was representative of the population they wanted to study and that the findings would be applicable to a broader context.

By following this group's social adjustment over time, the researcher can gain insights into the developmental trajectory of social skills, relationships, and adaptability. This longitudinal approach allows for a deeper understanding of how social adjustment evolves from childhood to adulthood within the selected sample, contributing valuable information to the field of research.

When continuous data points such as age or GPA are divided into groups, they have been reduced to discrete data.

This process of dividing continuous data into discrete categories is called "discretization" or "binning". Discretization can be useful in some cases, such as when we want to simplify data analysis or make data more understandable to non-experts. However, it can also lead to information loss, as we are losing some of the detailed information contained in the original continuous data.

Continuous data is a type of data that can take on any value within a given range. For example, age can be any value between 0 and infinity, and GPA can be any value between 0 and 4.0 (or higher, in some cases). These types of data are typically measured using numerical scales, such as inches, centimeters, or percentages.

However, when we divide continuous data points into groups, we are creating categories that can only take on certain values. For example, if we divide ages into groups of 10 years (e.g., 0-9, 10-19, 20-29, etc.), we are reducing the continuous data to a set of discrete categories. Similarly, if we divide GPAs into categories (e.g., 0-1.0, 1.1-2.0, 2.1-3.0, etc.), we are also reducing the continuous data to a set of discrete categories.

The fractions should be placed in the following order: 5/6 > 7/9 > 7/18

To arrange the fractions 7/18, 5/6, and 7/9 from greatest to smallest, we need to compare their values. One way to do this is to convert all the fractions to have the same denominator, which in this case is 54. To do this, we can multiply the numerator and denominator of each fraction by the appropriate factor to get a common denominator of 54:

7/18 = (7 x 3) / (18 x 3) = 21/54

5/6 = (5 x 9) / (6 x 9) = 45/54

7/9 = (7 x 6) / (9 x 6) = 42/54

Now we can compare these fractions:

45/54 > 42/54 > 21/54

So, the fractions in order from greatest to smallest are 5/6, 7/9, and 7/18. Therefore, the correct arrangement of the fractions is:

5/6 > 7/9 > 7/18

Nolan did not make an error while estimating the square root of number 18 and his all the steps are correct.

A real square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.

Nolan used the following procedure to find an estimate for

\(\sqrt{18}\)

The square of the number 4 is,

\(4^2=16\)

The square of the number 5 is,

\(5^2=25\)

Number 18 lies between these number as,

\(16 < 18 < 25\)

Therefore, the \(\sqrt{18}\) is somewhere between the number 4 and 5.

Since 18 is closer to 16, square the tenths closer to 4.

\({4. 1 }^2= 16. 81\\{4. 2 }^2= 17.64\\{4. 3}^2= 18.49\\{4. 4}^2= 19.36\\\)

This step is also correct, when squaring.

Since 18.49 rounds to 18, 4.3 is the best approximation for \(\sqrt{18}\).

All the above steps are correct.

Thus, Nolan did not make an error while estimating the square root of number 18 and his all the steps are correct.

Project A, which has a shorter period of future cash flows, will be more sensitive to changes in the discount rate compared to Project B with a relatively long period of future cash flows.

The discount rate is used to calculate the present value of future cash flows, and it reflects the time value of money and the risk associated with an investment. A higher discount rate implies a greater reduction in the present value of future cash flows. In the case of Project A, with a shorter period of future cash flows, any change in the discount rate will have a more significant impact on the present value of those cash flows. This is because the discounting effect is applied over a smaller time horizon, magnifying the impact of changes in the discount rate on the present value calculations. On the other hand, Project B, with a longer period of future cash flows, will be less sensitive to changes in the discount rate. The extended time period allows for a more gradual discounting effect, resulting in a relatively smaller impact on the present value of future cash flows. Therefore, due to the shorter period of future cash flows, Project A will exhibit higher sensitivity to changes in the discount rate compared to Project B.

The value of n cannot be included in any of the intervals generated by the bootstrap method. The number of intervals including n depends on the distribution of the estimates and the true value of n.

As the value of n is fixed and is not a result of any estimation or sampling process, it cannot be included in any of the intervals generated by the bootstrap method. Therefore, none of the intervals covering the middle 95% of the bootstrap estimates would include n.

However, as the bootstrap method is a resampling technique, the estimates generated by it can vary from sample to sample. Therefore, the number of intervals covering the middle 95% of the bootstrap estimates that include n would depend on the distribution of the estimates and the true value of n.

In general, if the estimates are centered around the true value of n, we would expect a higher number of intervals to include n. Conversely, if the estimates are more dispersed, we would expect a lower number of intervals to include n. Without further information about the estimates, it is difficult to provide a more specific answer.

Company A has a higher risk percentage (55%) compared to Company B (3%).

To compute the Coefficient of Variation (CV) for each company, we need to use the formula:

CV = (Standard Deviation / Mean) * 100

Let's calculate the CV for each company:

For Company A:

Risk Percentage = 55%

Return = 14%

For Company B:

Risk Percentage = 3%

Return = 14%

Since we don't have the standard deviation values for each company, we cannot calculate the exact CV. However, we can still compare the riskiness of the two companies based on the provided information.

The Coefficient of Variation measures the risk relative to the return. A higher CV indicates higher risk relative to the return, while a lower CV indicates lower risk relative to the return.

In this case, Company A has a higher risk percentage (55%) compared to Company B (3%), which suggests that Company A is riskier. However, without the standard deviation values, we cannot make a definitive conclusion about the riskiness based solely on the provided information. The CV would provide a more accurate measure for comparison if we had the standard deviation values for both companies.

To convert a decimal to a percentage, multiply it by 100, and to convert a percentage to a decimal, divide by 100. To convert a percentage to a fraction, convert it to a decimal, then write the decimal as a fraction.

To turn a fraction into a decimal, divide the numerator (the top number) by the denominator (the bottom number).

For example, if you want to turn 2/5 into a decimal,

divide 2 by 5:

= 2 ÷ 5

= 0.4.

The place value of the final digit can be used to convert a decimal to a fraction.

For instance, 0.5 may be expressed as 5/10 since it is in the tenths position.

By dividing the numerator and denominator by their largest common factor, in this example 5, you obtain 1/2 when you simplify the fraction.

Multiplying a decimal by 100 and adding the percent sign converts it to a percent.

For illustration, 50% might be expressed as 0.5.

Divide a percentage by 100 to convert it to a decimal.

For illustration, 75% may be expressed as 0.75. Write the percent as a fraction with a denominator of 100 to convert it to a fraction.

For illustration, 75% may be expressed as 75/100. Divide the fraction to make it simpler.

For instance, 4/5 = 0.8 = 80%.

When converting a decimal to a fraction, write the decimal as a fraction of the place value of the last digit. In the case of 0.25, the five is in the thousandth place, and so

Answer: 109.5 km/ hr

Step-by-step explanation:

Distance = 73 km

Time = 40 minutes = 40/60 = 2/3 hours

Speed = Distance / time

= 73 / 2/3

= 73 x 3/2 = 219 / 2 = 109.5 km/hr

The average speed of the train would be; 109.5 km/ hr

Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.

The speed formula is speed = distance / time.

We are given that train leaves at 08.43 and arrives at its destination at 09.23. If the train travelled 73 km then;

Distance = 73 km

Time = 40 minutes = 40/60 = 2/3 hours

Therefore, the Speed = Distance / time

Speed = 73 / 2/3

Speed = 73 x 3/2 = 219 / 2

Speed = 109.5 km/hr

Explanation:

Check out the diagram below.

We have the following points

Let x be the length of segments DE and EC. Note how segment AB bisects segment DC. Whenever the radius is perpendicular to the chord like this, the radius will bisect the chord.

We're told that the chord length CD is the same as the radius AD, since CD = CE+ED = x+x = 2x, this means AD = 2x as well.

At this point, you probably can recognize we have a 30-60-90 triangle. One useful property of such triangles is that the hypotenuse is double the length of the short leg. The long leg is \(x\sqrt{3}\) which is the length of segment EA. You can use the pythagorean theorem to confirm this.

----------------------------------

To summarize that last section, we formed triangle DAE and this triangle is a 30-60-90 triangle as shown in the diagram below.

Notice how the segments EA and FA span the entire width of the square. That width being \(EA+FA = x\sqrt{3}+x\sqrt{3} = 2x\sqrt{3} = EF\)

The square has side lengths of \(2x\sqrt{3}\) while the circle has radius 2x.

Use these two facts to find the area of each in terms of x.

\(A_1 = \text{area of square} = (\text{side})^2 = (2x\sqrt{3})^2 = 12x^2\)

\(A_2 = \text{area of circle} = \pi*r^2 = \pi*(2x)^2 = 4\pi x^2\)

-----------------------------------

The last step is to divide the two results. The x^2 terms cancel out.

We'll be left with...

\(\frac{A_1}{A_2} = \frac{12x^2}{4\pi x^2} = \frac{12}{4\pi} = \frac{3}{\pi} \approx 0.9549\)

There are many ways to express this ratio. One way we could write it is to say 3:pi to indicate that if the area of the square is 3, then the circle has area of pi (approximately 3.14). No matter what the square's area is, the circle is always slightly larger in area.
