Answer:

k = 13

Step-by-step explanation:

substitute x = x + 5 into f(x) , that is

f(x + 5) = (x + 5)² + 3(x + 5) - 10 ← expand squared factor using FOIL

          = x² + 10x + 25 + 3x + 15 - 10

         = x² + 13x + 30

compare this with f(x + 5) = x² + kx + 30

for the 2 expressions to be equal , then k = 13

Answer:

B

Step-by-step explanation:

The graph will shrink horizontally by 1/3 factor so option (B) must be correct.

A certain kind of relationship called a function binds inputs to essentially one output.

The function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given that,

Function = f(x)

Operation = f(3x)

By doing operation inside a function or in a dependent variable, it will cause the shrink of the horizontal aspect of the graph.

So by doing that operation graph will shrink horizontally by a factor of 1/3.

7 fishes οf the new released initially in the given expοnential pοpulatiοn grοwth. (οptiοn c)

Expοnential pοpulatiοn grοwth means that whatever the pοpulatiοn size is, it keeps increasing because the pοpulatiοn per individual remains the same, accelerating pοpulatiοn grοwth that is limited by limited resοurces.

The standing wave is in the fifth harmonic because the supplied standing wave pattern includes five nodes.

In both open and closed pipes, the air column serves as a resonating column for the sound waves. A closed pipe has one open end, whereas an open pipe has both ends open. Standing waves are produced when a medium's impedance abruptly changes, forming a border where the sound wave may be partially or fully reflected, transmitted, or reflected at all. The two antinodes at either end of the tube are included in the six antinodes that are visible.

Open ends will always be antinodes in any pipe. As a result, the provided pipe is either open or open-open.

The first harmonic of the fundamental mode of oscillation in an open pipe will contain a node in the centre and two antinodes at either end. Two antinodes at the open ends, one in the middle, and two nodes down the length of the pipe make up the second harmonic. Similar to the third harmonic, the fourth harmonic has five antinodes and four nodes, the fifth harmonic has six antinodes and three nodes, and so on.

The complete question is:

The pattern of displacement nodes (n) and antinodes (a) in a pipe is nanananana when the standing-wave frequency is 1390 Hz. The pipe contains air at 20°C, and the speed of sound in air is 344 m/s.

To find the wavelength of the standing wave, we can use the equation:

λ = v/f

Where λ is the wavelength, v is the speed of sound, and f is the frequency. Plugging in the values given in the question:

λ = 344 m/s / 1390 Hz = 0.247 m

Since the pattern in the pipe is nanananana, we can see that there are 5 nodes and 4 antinodes. The distance between each node and antinode is λ/4, so the length of the pipe is:

L = (5 nodes + 4 antinodes) * (λ/4) = 9 * (0.247 m / 4) = 0.556 m

Therefore, the length of the pipe is 0.556 m.

So, using a calculator, tan(20) is approximately equal to 0.363. This times 6 should equal a. This is approximately around 2.1. Thus our answer is 2.1

The value of the test statistic is 1.177.

What is test statistic?

A test statistic is a numerical summary of sample data that is used in hypothesis testing. It is used to assess the strength of evidence against a null hypothesis by comparing the observed data to what would be expected if the null hypothesis were true.

To find the value of the test statistic, we need to use the formula:

test statistic = (sample statistic - hypothesized parameter) / (standard error of the sample statistic)

In this case, the hypothesized parameter is the standard deviation of pulse rates of adult males, which is stated to be more than 12 bpm. So, we have:

hypothesized parameter: σ > 12 bpm

sample size: n = 141

sample standard deviation: s = 13.4 bpm

To calculate the standard error of the sample standard deviation, we use the formula:

standard error of s = σ / √n

Since we don't know the value of σ, we will use the sample standard deviation s as an estimate for it:

standard error of s = s / √n = 13.4 / √141 = 1.126

Now, we can plug in the values into the formula for the test statistic:

test statistic = (s - σ) / (standard error of s)

= (13.4 - 12) / 1.126

= 1.177

Therefore, the value of the test statistic is 1.177.

False. The statement is false. The Naive Bayes method is not typically used to represent dependency structure in a graphical, explicit, and intuitive way.

Naive Bayes is a probabilistic machine learning algorithm that is commonly used for classification tasks. It assumes that the features are conditionally independent given the class label. This assumption simplifies the modeling process by assuming that the features contribute independently to the probability of the class. However, Naive Bayes does not explicitly represent or capture the dependency structure between features.

Graphical models, such as Bayesian networks, are specifically designed to represent and visualize dependency structures among variables. Bayesian networks use graphical representations with nodes and edges to represent variables and their conditional dependencies. Each node in the graph represents a random variable, and the edges indicate the probabilistic dependencies between variables.

While Naive Bayes can be viewed as a special case of a Bayesian network with strong independence assumptions, it does not provide a graphical representation of the dependency structure. Naive Bayes assumes independence among features, which may not reflect the true dependencies present in the data.

Therefore, the statement that the Naive Bayes method is a powerful tool for representing dependency structure in a graphical, explicit, and intuitive way is false. It is more appropriate to use graphical models like Bayesian networks when the explicit representation of dependency structure is desired.

Answer:

30 points

Step-by-step explanation:

It sounds like you have a game where you spin a wheel that has four sectors with different point values assigned to them. The chart shows the central angle and the corresponding point value for each sector.

To calculate the expected value (average score) for a single spin of the wheel, you need to multiply each point value by the probability of landing in that sector, and then add up the results. The probability of landing in each sector can be calculated by dividing the central angle of the sector by the total central angle of the wheel (which is 360 degrees).

So, let's calculate the expected value:

Sector 1: Central angle = 144°, Point value = 20

Probability = 144° / 360° = 0.4

Contribution to expected value = 0.4 * 20 = 8

Sector 2: Central angle = 108°, Point value = 30

Probability = 108° / 360° = 0.3

Contribution to expected value = 0.3 * 30 = 9

Sector 3: Central angle = 72°, Point value = 40

Probability = 72° / 360° = 0.2

Contribution to expected value = 0.2 * 40 = 8

Sector 4: Central angle = 36°, Point value = 50

Probability = 36° / 360° = 0.1

Contribution to expected value = 0.1 * 50 = 5

Total expected value = 8 + 9 + 8 + 5 = 30

Therefore, the expected value for a single spin of the wheel is 30 points

Answer:

What is the expected value of the points earned if the wheel is spun once?

To find the expected value, we need to multiply each point value by its corresponding probability and then add up these products. The probability of landing on each sector can be found by dividing the central angle of that sector by the total central angle of the circle, which is 360 degrees. So we have:

Probability of landing on 20 points: 144°/360° = 0.4

Probability of landing on 30 points: 108°/360° = 0.3

Probability of landing on 40 points: 72°/360° = 0.2

Probability of landing on 50 points: 36°/360° = 0.1

Now we can calculate the expected value:

Expected value = (20 x 0.4) + (30 x 0.3) + (40 x 0.2) + (50 x 0.1)

Expected value = 8 + 9 + 8 + 5

Expected value = 30

Therefore, the expected value of the points earned if the wheel is spun once is 30.

The solutions of the equation sec² x - 4 = 0 are x = π/3 + 2kπ, 2π/3 + 2kπ, 4π/3 + 2kπ, 5π/3 + 2kπ. Therefore, option d. is correct.

We start by solving for x in the equation sec² x - 4 = 0:

sec² x - 4 = 0
sec² x = 4
sec x = ±2

Recall that sec x = 1/cos x, so we can rewrite the equation as:

1/cos² x = 4
cos² x = 1/4
cos x = ±1/2

Now we need to find all values of x that satisfy cos x = ±1/2. These values are:

x = π/3 + 2kπ or x = 5π/3 + 2kπ (for cos x = 1/2)
x = 2π/3 + 2kπ or x = 4π/3 + 2kπ (for cos x = -1/2)

Combining these solutions, we get:
x = π/3 + 2kπ, 2π/3 + 2kπ, 4π/3 + 2kπ, 5π/3 + 2kπ

Therefore, the correct answer is d. pi/3 + 2k pi, 2pi/3 + 2k pi, 4pi/3 + 2k pi, 5pi/3 + 2k pi.
