It is

\( {10}^{5} \)

Step-by-step explanation:

\( \frac{ {10}^{4}. {10}^{5} . {10}^{6} }{ {10}^{3} . {10}^{7} } = \frac{ {10}^{(4 + 5 + 6)} }{ {10}^{(3 + 7)} } \\ \\ = \frac{ {10}^{15} }{ {10}^{10} } \\ \\ = {10}^{(15 - 10)} \\ = {10}^{5} \)

The 50th percentile is a commonly used statistic in data analysis. It represents the value below which 50% of the data falls.

In other words, it divides the data into two equal parts. There are two other statistics that have the same value as the 50th percentile, namely the second quartile and the median. The second quartile is the middle value of the data when it is arranged in ascending or descending order.

It is also known as the 50th percentile or the median. The first quartile is the value below which 25% of the data falls, and the third quartile is the value below which 75% of the data falls.

The mean is another commonly used statistic in data analysis. It is the sum of all the values in the data divided by the total number of values. Unlike the median, the mean is affected by extreme values or outliers in the data. This means that if there are outliers in the data, the mean may not be a good measure of central tendency.

The mode is the value that occurs most frequently in the data. It is another measure of central tendency that can be used in addition to the median and mean.

In summary, the 50th percentile is equivalent to the second quartile and the median. These statistics are all measures of central tendency that help to describe the distribution of data. The choice that best answers the question is option A: Second quartile; median.

The margin of error for an 80% confidence interval, based on a sample of 150 students with a mean cost of $371.75 and a sample standard deviation of $39.09, is approximately $5.29. This represents the range within which we expect the population mean to fall with 80% confidence.

To find the margin of error for an 80% confidence interval, we first need to determine the critical value associated with the confidence level.

Since the population standard deviation is unknown, we will use the t-distribution. For an 80% confidence interval with 150 - 1 = 149 degrees of freedom, the critical value can be obtained from the t-distribution table or calculator.

The formula for the margin of error is:

\(\text{Margin of Error} = Z_{\alpha/2} \cdot \frac{\sigma}{\sqrt{n}}\)

The critical value corresponding to an 80% confidence level with 149 degrees of freedom is approximately 1.653.

Substituting the values into the formula:

\(\[\text{Margin of Error} = 1.653 \cdot \frac{39.09}{\sqrt{150}}\]\)

Calculating the expression:

Margin of Error ≈ 1.653 * (39.09 / 12.247)

Margin of Error ≈ 5.29 (rounded to two decimal places)

Therefore, the margin of error for an 80% confidence interval is approximately $5.29.

Solving the provided question, we can say that The quadratic equation is \(y^{2}+3{\frac{\sqrt{5}}{2}y} - 5=0\), the value of \(y = -2\sqrt{5}\)

A quadratic polynomial in a single variable is represented by the equation \(ax^{2}+bx+c=0\). a 0.

Since this polynomial is of second order, the Fundamental Theorem of Algebra guarantees that it has at least one solution.

There are both simple and complex solutions. A quadratic equation is just that—quadratic.

It has at least one word that has to be squared, as shown by this. One of the often used solutions for quadratic equations is "\(ax^{2}+bx+c=0\)." where X is an undefined variable and a, b, and c are numerical coefficients or constants.

The quadratic equation is \(y^{2}+3{\frac{\sqrt{5}}{2}y} - 5=0\)

Taking 2 as LCM,

Let \(2y^{2} + 3\sqrt{5} y - 10 = 0\)

On factoring,

\(2y^{2} + 4\sqrt{5} y - \sqrt{5}y - 10 = 0\)

\(2y(y + 2\sqrt{5} ) - \sqrt{5} (y - 2\sqrt{5} ) = 0\)

\((y + 2\sqrt{5} )(2y - \sqrt{5} ) = 0\)

Now, \(y + 2\sqrt{5} = 0\)

\(y = -2\sqrt{5}\)

Also, \(2y - \sqrt{5} = 0\)

\(2y = \sqrt{5}\)

\(y = \sqrt{5} /2\)

The locus of points equidistant from the sides of a triangle is called the Incenter. In other words, the Incenter is the point that is equidistant from each side of the triangle.

To construct the Incenter of a triangle, one can draw the angle bisectors of each angle of the triangle. The three angle bisectors intersect at a single point, which is the Incenter. The Incenter is also the center of the circle that is inscribed in the triangle, which is called the Incircle.

The Incenter has some interesting properties. For example, it is the center of the largest circle that can be inscribed in the triangle. This circle is called the Incircle, and it is tangent to each side of the triangle at a single point. Additionally, the distance from the Incenter to any side of the triangle is equal to the radius of the Incircle.

The Incenter also plays an important role in geometry and trigonometry. It is used in various formulas to find the area, perimeter, and angles of a triangle. For instance, the formula for the area of a triangle in terms of its Inradius (the radius of the Incenter) is A = rs, where A is the area, r is the Inradius, and s is the semi perimeter (half of the perimeter).

The confidence interval for the proportion of adults who identify chocolate pie as their favorite pie, with a confidence level of 98%, is approximately  0.3248 to 0.8152 (rounded to four decimal places).

To calculate the confidence interval for the proportion of adults who identify chocolate pie as their favorite pie, we can use the formula:

Confidence Interval = Sample Proportion ± Margin of Error

First, let's calculate the sample proportion:Sample Proportion = Percentage/100 = 57/100 = 0.57

Next, we need to calculate the margin of error using the formula:Margin of Error = Critical Value * Standard Error

Since the confidence level is 98%, the alpha level (α) is 1 - 0.98 = 0.02. Since it is a two-tailed test, we divide the alpha level by 2, resulting in α/2 = 0.01.

The critical value can be found using a standard normal distribution table or a calculator, based on the alpha level. In this case, the critical value for a 98% confidence level is approximately 2.33.

The standard error is calculated as the square root of [(Sample Proportion * (1 - Sample Proportion)) / Sample Size].

Standard Error = sqrt[(0.57 * (1 - 0.57)) / 22]

Now we can calculate the margin of error: Margin of Error = 2.33 * sqrt[(0.57 * (1 - 0.57)) / 22]

Finally, we can calculate the confidence interval:Confidence Interval = Sample Proportion ± Margin of Error. Substituting the values: Confidence Interval = 0.57 ± Margin of Error

Therefore, the confidence interval for the proportion of adults who identify chocolate pie as their favorite pie, with a confidence level of 98%, is approximately 0.3248 to 0.8152 (rounded to four decimal places).

Step-by-step explanation: A characteristic, usually a numerical value, which describes a sample, is called a statistic.

The ROI per unit for Jaymes Corporation's rotors is $200.

To calculate the ROI per unit, we need to divide the total return on investment by the number of units produced. In this case, the company has invested $6,000,000 to produce 30,000 rotors.

ROI per unit = Total ROI / Number of units produced

Total ROI = $6,000,000

Number of units produced = 30,000

ROI per unit = $6,000,000 / 30,000 = $200

Therefore, the ROI per unit for Jaymes Corporation's rotors is $200. This means that for every rotor produced, the company expects to generate a return of $200.
