Question given

Ray XP is the angle bisector of Angle RXQ. Given the measure of Angle RXP 12x and Angle PXQ = 8x +12, What is the measure of Angle PXQ?​

Solution

Since XP is the angle bisector of the angle RXQ then we can conclude that the angle RXP is equal to PXQ so we can do the following operation:

And we can solve for the value of x and we got:

And then we can solve for the value of the angle PXQ and we got:

a) P(3) = \(\frac{11}{100}\) (or 0.11 or 11%)

b) Number of sixes = P(6) x 500

                                = \(\frac{12}{100}\) x 500

                                = 12 x 5

                                = 60

One dimension, called "media richness," is used to classify social media and is shown on the x-axis of Figure 20-1. It ranges from "words" to "animation" and represents the level of interactivity and information.

In the context of social media, the concept of media richness refers to the degree of richness or complexity in the communication channel. It is a measure of the ability of a medium to convey information effectively, facilitate understanding, and support interaction between users.

Media richness is influenced by factors such as the presence of nonverbal cues, immediate feedback, personalization, and the capacity for multiple communication channels. Figure 20-1 likely represents a graphical representation or classification of social media based on their media richness.

The x-axis of the figure represents the continuum of media richness, ranging from "words" to "animation." At one end of the spectrum, "words" represent text-based communication platforms that primarily rely on written content. As we move towards the other end, "animation" represents media that incorporate rich visual and interactive elements such as videos, graphics, and multimedia features.

By placing different social media platforms along this dimension, Figure 20-1 provides a visual representation of their relative media richness levels. It helps in understanding the varying capabilities and characteristics of different social media platforms and their potential for communication, engagement, and information sharing.

Answer:

(f О g)(25) is -135

Step-by-step explanation:

The composite function (f О g)(x) means substitute x in f by g

∵ f(x) = -2x² - 7

∵ g(x) = √3 + 3

→ To find (f О g)(25), find g(25) first, then substitute x in f by the value of g(25)

∵ x = 25

∴ g(25) = √25 + 3

∵ √25 = 5

∴ g(25) = 5 + 3

∴ g(25) = 8

→ Now substitute x in f by 8

∵ x = 8

∴ f(8) = -2(8)² - 7

∴ f(8) = -2(64) - 7

∴ f(8) = -128 - 7

∴ f(8) = -135

∴ (f О g)(25) = -135

Answer:

0.5625

Step-by-step explanation:

Answer:

Step-by-step explanation:

To use Holt's method with smoothing constants of 0.3 for alpha and 0.6 for gamma, we first need to calculate the initial values for the level and slope.

Let L0 be the initial level and B0 be the initial slope. We can estimate these using the following equations:

L0 = y1

B0 = y2 - y1

where y1 and y2 are the first two observed values in the time series.

Once we have the initial values, we can use the following recursive equations to calculate the level and slope at each time period t:

Lt = alpha * yt + (1 - alpha) * (Lt-1 + Bt-1)
Bt = gamma * (Lt - Lt-1) + (1 - gamma) * Bt-1

where yt is the observed value at time t.

Using these equations and the given smoothing constants, we can find the equation of the forecast line as:

Ft+1 = Lt + Bt

and the mean squared error (MSE) as:

MSE = (1 / n) * sum((yt - Ft)^2)

where n is the number of observed values.

Robert, Juan, Susan, and Linda scored above the mean, Joel scored on the mean, and Jan scored below the mean on the advanced first aid course's final exam based on their z-score. Their final exam scores were 172, 184, 190, 150, 166, and 182, respectively.

The students with positive z-scores scored above the mean. So, Robert, Juan, Susan, and Linda scored above the mean. The student with a z-score of 0.00 scored on the mean. So, Joel scored on the mean. The student with a negative z-score scored below the mean. So, Jan scored below the mean.

To find the final exam score for each student, we can use the formula:

z = (x - m) / s

where z is the z-score, x is the final exam score, m is the mean score, and s is the standard deviation.

Rearranging the formula, we get:

x = z * s + m

Using the given values of z, s, and m, we can find the final exam score for each student:

Robert: x = 1.10 * 20 + 150 = 172

Juan: x = 1.70 * 20 + 150 = 184

Susan: x = 2.00 * 20 + 150 = 190

Joel: x = 0.00 * 20 + 150 = 150

Jan: x = 0.80 * 20 + 150 = 166

Linda: x = 1.60 * 20 + 150 = 182

So, the final exam scores for Robert, Juan, Susan, Joel, Jan, and Linda are 172, 184, 190, 150, 166, and 182, respectively.

Answer:

To answer the questions regarding Mokoena's and his brother's ages, we'll use the given information:

Mokoena is p years old.

His brother is twice his age.

2.1 How old is his brother?

Since his brother is twice Mokoena's age, his brother's age would be 2p.

2.2 How old will Mokoena be in 10 years?

To find Mokoena's age in 10 years, we add 10 to his current age: p + 10.

2.3 How old was his brother 3 years ago?

To find his brother's age 3 years ago, we subtract 3 from his brother's current age: 2p - 3.

2.4 What will their combined age be in q years' time?

To find their combined age in q years' time, we add q to the sum of their current ages: p + 2p + q = 3p + q.

Therefore, the answers are:

2.1 His brother's age is 2p.

2.2 Mokoena will be p + 10 years old in 10 years.

2.3 His brother was 2p - 3 years old 3 years ago.

2.4 Their combined age in q years' time will be 3p + q.

Step-by-step explanation:

The value of a painting in 1978 was $274, and in 1985, it was sold for $409. Assuming the growth rate of the collector's item was exponential, we need to find the growth rate constant k and the exponential growth function V(t). The estimated value of the painting in 2011 needs to be calculated, along with the doubling time and the time taken for the painting's value to be $2588.

a) To find the growth rate constant k, we can use the formula V = Vo*e^(kt), where Vo is the initial value, and t is the time elapsed. Substituting the given values, we get 409 = 274*e^(7k). Solving for k, we get k = 0.0806 (rounded to the nearest thousandth).
b) The exponential growth function in terms of t can be found by substituting the value of k in the formula V = Vo*e^(kt). Therefore, V(t) = 274*e^(0.0806t).
c) To estimate the value of the painting in 2011, we need to find the value of V(t) when t = 33 (2011-1978). Substituting the value, we get V(33) = 274*e^(0.0806*33) = $2,078 (rounded to the nearest dollar).
d) The doubling time can be found using the formula t = ln(2)/k. Substituting the value of k, we get t = ln(2)/0.0806 = 8.6 years (rounded to the nearest tenth).
e) To find the time taken for the painting's value to be $2588, we need to solve the equation 2588 = 274*e^(0.0806t) for t. After solving, we get t = 41.1 years (rounded to the nearest tenth).

The growth rate constant k for the painting's value was found to be 0.0806, and the exponential growth function V(t) was estimated to be V(t) = 274*e^(0.0806t). The estimated value of the painting in 2011 was $2,078, and the doubling time for the painting's value was 8.6 years. Finally, the time taken for the painting's value to be $2588 was calculated to be 41.1 years.

Step-by-step explanation:

I don't know what are you in, geometry or algebra? I'll post my way of solution. It may need some calculator calculation that I can't give detail of steps here. I just like to explore something, wish it help.

suppose D is the origin, DA = 4 and AB = 5

A (0,4)    B(5,4)    C(5,0)    D(0,0)

AE/AC = 3/4   (i.e. AE/EC = 3/1)

CF/BC = CE/AC = 1/4

CF = BC x 1/4 = 4 x 1/4 = 1

DG/DC = AE/AC = 3/4  

DG = DC x 1/4 = 5 x 3/4 = 15/4
