The height of woman who has a shoulder width of 18.5 inches is 74 inches.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Height of woman = 64 inches

Shoulder width = 16 inches

So, ratio = Height :  shoulder width = 64:16

let the height of a woman who has a shoulder width of 18.5 inches be x.

So, x:18.5.

Now,

64 / 16 =  x/ 18.5

4= x/18.5

x= 74

Hence, the height of woman who has a shoulder width of 18.5 inches is 74 inches.

Considering the sampling distribution of the sample mean, P(X < 14) ≈ 0.0336. The null hypothesis is H0: μ ≥ 15 and the alternative hypothesis is H1: μ < 15. The population standard deviation is assumed to be the same as the original population (2.4 hours)

(a) To determine P(X < 14), we need to calculate the z-score and find the corresponding probability from the standard normal distribution. The z-score formula is given by:

\(z = (X - \mu) / (\sigma / \sqrt{n} )\)

Where X is the sample mean (14 hours), μ is the population mean (15 hours), σ is the population standard deviation (2.4 hours), and n is the sample size (20).

Substituting the values, we have:

z = (14 - 15) / (2.4 / √20) ≈ -1.83

Using a standard normal distribution table or calculator, we can find the probability corresponding to a z-score of -1.83, which is approximately 0.0336. Therefore, P(X < 14) ≈ 0.0336.

(b) The null hypothesis (H0) for this test would be that the average training time by the new instructors is equal to or greater than 15 hours. The alternative hypothesis (H1) would be that the average training time by the new instructors is less than 15 hours.

H0: μ ≥ 15

H1: μ < 15

To test this hypothesis, a one-sample t-test is appropriate since the population standard deviation (σ) is unknown and we are estimating it based on the sample data.

(c) To determine the p-value of the test, we need to calculate the t-statistic and find the corresponding probability from the t-distribution with (n - 1) degrees of freedom.

The t-statistic formula is given by:

\(t = (X - \mu) / (s / \sqrt{n} )\)

Where X is the sample mean (14 hours), μ is the hypothesized population mean under the null hypothesis (15 hours), s is the sample standard deviation, and n is the sample size (20).

Since the population standard deviation is assumed to be the same as the original population (2.4 hours), we can use the sample standard deviation as an estimate. However, the sample standard deviation is not given in the information provided, so we cannot proceed with calculating the p-value without that information.

In conclusion, without the sample standard deviation, we cannot determine the p-value or make a conclusion regarding the training times. The missing information is crucial for performing the hypothesis test and evaluating the significance of the results.

The correct answer is b. Characteristic equation. the equation formed by equating the denominator of a transfer function to zero is known as the characteristic equation.

In control systems theory, the characteristic equation is formed by equating the denominator of a transfer function to zero. It plays a crucial role in the analysis and design of control systems.

The transfer function of a control system is represented as the ratio of the Laplace transform of the output to the Laplace transform of the input. The denominator of the transfer function represents the characteristic equation, which is obtained by setting the denominator polynomial equal to zero.

The characteristic equation is an algebraic equation that relates the input, output, and system dynamics. By solving the characteristic equation, we can determine the system's poles, which are the values of the complex variable(s) that make the denominator zero. The poles of the system are crucial in understanding the system's stability and behavior.

The characteristic equation helps in determining the stability of a control system. If all the poles of the characteristic equation have negative real parts, the system is stable. On the other hand, if any pole has a positive real part or lies on the imaginary axis, the system is unstable or marginally stable.

Moreover, the characteristic equation is used to calculate important system properties such as the natural frequency, damping ratio, and transient response. These properties provide insights into the system's performance and behavior.

In summary, it plays a fundamental role in control systems analysis and design, allowing us to determine system stability, transient response, and other important properties.

Given a function, \(f(x) = x^2 + x\) and the graph of the function has been plotted. The slope of the secant line joining (-4, f(-4)) and (0, f(0)) is -2.

The problem can be solved by finding the slope of the secant line joining the two points (-4, f(-4)) and (0, f(0)). We know that the slope of the secant line joining any two points on a curve is given by the difference quotient. By plugging in the values of the two points, we can find the slope of the secant line. The difference quotient is the formula used to find the slope of a secant line.

We know that the slope of the secant line joining any two points on a curve is given by:

\($$\frac{f(x_2) - f(x_1)}{x_2 - x_1}$$\)

Here, x1 = -4, x2 = 0.

Therefore,\($$\frac{f(x_2) - f(x_1)}{x_2 - x_1} = \frac{f(0) - f(-4)}{0 - (-4)}$$\)

We know that , \(f(x) = x^2 + x\) Therefore, f(0) = 0 and f(-4) = 8.

Substituting these values, we get,$

\($\frac{f(x_2) - f(x_1)}{x_2 - x_1} = \frac{0 - 8}{0 - (-4)} = \frac{-8}{4} = -2$$\)

Therefore, the slope of the secant line joining (-4, f(-4)) and (0, f(0)) is -2.

Thus, we found the slope of the secant line joining (-4, f(-4)) and (0, f(0)) to be -2.

The figure shows three types of unconformities: an angular unconformity (A - A) with tilted and eroded layers, a non-conformity (B- B) between uplifted and underlying rocks, and a paraconformity (C - C ) with a smooth transition between sedimentary layers indicating a potential time gap.

Based on the information provided, the figure shows three different unconformities

(A - A) represents an angular unconformity:

This occurs when horizontally layered rocks (A) are tilted or folded, eroded, and then overlain by younger, undeformed rocks (A). The angular discordance between the older and younger layers indicates a significant period of deformation and erosion.

(B- B) represents a non-conformity:

A non-conformity occurs when igneous or metamorphic rocks (B) are uplifted and eroded, exposing the underlying, usually sedimentary, rocks (B). The boundary between the two types of rocks represents a significant time gap and a change in the geological history of the area.

(C - C) represents a paraconformity:

A paraconformity is a type of unconformity where there is a relatively smooth transition between parallel layers of sedimentary rocks (C - C). Unlike angular unconformities and non-conformities, paraconformities do not show significant tilting, folding, or erosion. The time gap between the two layers may still exist, but it is often difficult to distinguish due to the lack of obvious discontinuities.

In summary, an angular unconformity (A - A) shows significant tilting and erosion, a non-conformity (B - B) indicates an uplift and erosion of older rocks, and a paraconformity (C - C) represents a relatively smooth transition between parallel sedimentary layers with a potential time gap.

The midpoint is the point that divides a line or segment into two same or equal sections. When a line has length A and the midpoints should be :

A/2

From the question we know that :

P is the midpoint of DE

DP = 3x + 2

DE = 10x - 12

By applying the midpoint rule, we get

DP = 1/2 x DE

3x + 2 = 1/2 (10x - 12)

3x + 2 = 5x - 6

2x = 8

x = 4

Substitute x to DP and DE

DP = 3x + 2

DP = 3(4) + 2

DP = 12 + 2

DP = 14

DE = 10x - 12

Answer:

36°; 108°

Step-by-step explanation:

The measure of each interior angle of a regular pentagon is 108°.a) Two consecutive radii are joined to form an angle. The sum of these two angles is equal to 360° as a full rotation. Therefore, each angle formed by two consecutive radii measures (360°/5)/2 = 36°.b) A radius and a side of the polygon form an isosceles triangle with two base angles of equal measure. The sum of the angles of this triangle is 180°. Therefore, the measure of the angle formed by a radius and a side is (180° - 108°)/2 = 36°. Thus, the angle formed by the radius and the side plus two consecutive radii angles equals 180°. Hence, the angle formed by a radius and a side measures (180° - 36° - 36°) = 108°.Therefore, the measures of the angles formed by two consecutive radii and a radius, and a side of the polygon are 36° and 108°, respectively. Thus, the answer is 36°; 108°.
