True when desired information of Census is available for all objects in the population

A census is a study that collects data from every member of a population, making it the most comprehensive form of data collection.

A census can provide highly accurate information on the entire population, without any risk of sampling error.

However, conducting a census can be time-consuming and costly, especially for large populations, and may not always be practical or feasible. In some cases, a sample study may be a more practical approach, as it can provide accurate information with less time and cost.

However, it's important to carefully consider the sampling design to ensure that the sample is representative of the population, in order to minimize sampling bias.

Part A: The real part of (A + B) is 9.7

Part B: The imaginary part of (A + B) is approximately 5.68

Part C: The real part of (A - B) is -3.5

Part D: The imaginary part of (A - B) is approximately -0.14.

Given that,

A = 3.1∠63.2°  

B = 6.6∠26.2°

Part A: To find the real part of (A + B), we add the real parts of A and B.

In this case,

The real part of A is 3.1 and the real part of B is 6.6.

Adding them together, we get:

Real part of (A + B) = 3.1 + 6.6 = 9.7

So, the real part of (A + B) is 9.7.

Part B: To find the imaginary part of (A + B),

Add the imaginary parts of A and B.

In this case,

The imaginary part of A can be calculated using the formula

A x sin(angle),

Which gives us:

Imaginary part of A = 3.1 x sin(63.2°)

                                ≈ 2.77

Similarly, for B:

Imaginary part of B = 6.6 x sin(26.2°) ≈ 2.91

Adding these together, we get:

Imaginary part of (A + B) ≈ 2.77 + 2.91

                                        ≈ 5.68

So, the imaginary part of (A + B) is approximately 5.68.

Part C: To find the real part of (A - B),

Subtract the real part of B from the real part of A.

In this case,

The real part of A is 3.1 and the real part of B is 6.6.

Subtracting them, we get:

Real part of (A - B) = 3.1 - 6.6

                               = -3.5

So, the real part of (A - B) is -3.5.

Part D: To find the imaginary part of (A - B),

Subtract the imaginary part of B from the imaginary part of A.

Using the previously calculated values, we have:

Imaginary part of (A - B) ≈ 2.77 - 2.91

                                        ≈ -0.14

So, the imaginary part of (A - B) is approximately -0.14.

Answer:

BF = |4 – 1| = 3

FC = |4 – 0| = 4

Using the Pythagorean Theorem to find BC:

BC2  =  BF2 + FC2

BC2   =  32 + 42

BC2   =  9 + 16

BC  =  sqaure root 25

BC  =  5

Step-by-step explanation:

The length of BC is 5 unit.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

We need to find the length of BC place point F at (4,4) and draw BF and FC now you have the right ∆BFC with BC as the hypotenuse find BC and FC using the coordinates of B,C, and,F then use the Pythagorean theorem to find BC.

Using the Pythagorean Theorem to find BC:

BC^2  =  BF^2 + FC^2

BC^2   =  32 + 42

BC^2   =  9 + 16

BC  =  √25

BC  =  5

So, BF = |4 – 1| = 3

FC = |4 – 0| = 4

The total number of questions on the test is 75 questions.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Total number of answers answered correctly = 69

The percentage of the test questions answered correctly = 92%

This means,

92% = 69

The total number of questions in percentage = 100%

Now,

92% = 69

Multiplying 100/92 on both sides.

100% = 100/92 x 69

100% = 75

Step-by-step explanation:

Fallacies of relevance are types of logical fallacies that occur when an argument is presented without a relevant connection to the subject matter.

Rather than addressing the topic, these fallacies are aimed at the listener's feelings, emotions, or biases.There are many different types of fallacies of relevance, but some of the most common are ad hominem, straw man, appeal to authority, and red herring. Ad hominem, for example, is a type of fallacy that attacks the speaker rather than addressing the argument they are presenting.. It can undermine the quality of your argument and make you seem less credible.

However, if you want to describe a time when you used these fallacies, you might think back to a situation where you were arguing with someone and felt like you were losing the argument. In this case, you might have resorted to a fallacy of relevance to try to regain control of the conversation. In conclusion, it is important to avoid using fallacies of relevance in your arguments. Instead, focus on addressing the topic at hand and presenting logical, evidence-based arguments.

The exact value of y is π/4, which is approximately 0.7854 radians or 45 degrees.

To find the exact value of the real number y using y = arctan(-1), we can evaluate the arctan function at -1.

The arctan function gives us the angle whose tangent is a given value. In this case, we want to find the angle whose tangent is -1.

Since the tangent of π/4 is equal to 1, we can write -1 as -tan(π/4).

Therefore, y = arctan(-1) = arctan(-tan(π/4)).

Now, arctan and -tan are inverse functions, so they cancel each other out, resulting in:

y = π/4.

Therefore, the exact value of y is π/4, which is approximately 0.7854 radians or 45 degrees.

Variable c is acting as a confounding variable in this experiment. A confounding variable is an extraneous variable that is related to both the independent variable and the dependent variable.

It can influence the results of an experiment and create a false relationship between the independent and dependent variables.

In this case, the researcher initially believed that variable x was causing the changes in variable y, but it turns out that the changes were actually caused by variable c.

To avoid confounding variables, researchers need to carefully design their experiments and control for any potential confounders.

This can be done through randomization, controlling the environment, or using statistical techniques like analysis of covariance.

By doing so, researchers can ensure that any observed changes in the dependent variable are truly due to the manipulation of the independent variable.

δ10 is approximately equal to -25.5 ln(0.6) based on the given function a(t).

To calculate δ10, we need to evaluate the integral of a(t) from t = 0 to t = 10.

Let's break down the process step by step:

Given: \(a(t) = (1.02)t(1 - 0.04t)^{-1\)

Integrate the function a(t).

\(\int a(t) dt = \int(1.02)t(1 - 0.04t)^{-1} dt\)

Apply the substitution method.

Let u = 1 - 0.04t

Then, du = -0.04 dt, or dt = -du/0.04

Rewriting the integral with the substitution:

\(\int(1.02)t(1 - 0.04t)^{-1}dt = \int(1.02)t/u (-1/0.04) du\)

= -25.5 ∫ t/u du

Step 3: Integrate with respect to u.

-25.5 ∫ t/u du = -25.5 ln|u| + C

= -25.5 ln|1 - 0.04t| + C

Evaluate the definite integral.

To calculate δ10, we substitute the upper and lower limits of integration into the antiderivative:

δ10 = [-25.5 ln|1 - 0.04t|] from 0 to 10

= [-25.5 ln|1 - 0.04(10)|] - [-25.5 ln|1 - 0.04(0)|]

= [-25.5 ln|0.6|] - [-25.5 ln|1|]

= -25.5 ln|0.6|

Using a calculator, we can evaluate the natural logarithm:

δ10 ≈ -25.5 ln(0.6)

Answer: P(rolling a sum of 4 or rolling a sum of 5)

Step-by-step explanation: edge2023

The scenario that uses the addition rule for mutually exclusive events is:

p(rolling a sum of 4 or rolling a sum of 5) = p(rolling a sum of 4) + p(rolling a sum of 5)

This is because the events "rolling a sum of 4" and "rolling a sum of 5" are mutually exclusive, meaning that they cannot occur at the same time. Therefore, the probability of either event occurring is the sum of their individual probabilities.

The probability of rolling a sum of 4 is 3/36, and the probability of rolling a sum of 5 is 4/36. The addition rule states that the probability of rolling a sum of 4 or 5 is the sum of their individual probabilities: 3/36 + 4/36 = 7/36

The other scenarios do not use the addition rule for mutually exclusive events:

p(rolling a sum of 4) is a single event and does not involve a second event.

p(rolling a sum of 12 or rolling a double 6) although the two events are mutually exclusive, it's not the sum of their individual probabilities.

p(rolling a sum of 11 and rolling a sum of 12) these events are not mutually exclusive, they can happen at the same time, so it's not the sum of their individual probabilities.

The statement "If a set of vectors {v₁, v₂, ...., vp} in Rⁿ is linearly dependent, then p>n" is False.

Let {v₁, v₂, ...., vp} be a set of p vectors in Rⁿ, then the following are equivalent statements:

1. The set of vectors is linearly dependent.

2. There exist constants c₁, c₂, ... cp, not all of them zero, such that:

c₁v₁+c₂v₂+...+cpvp = 0 (zero vector)

For the above to be possible, the following must hold true: p≥n

Because in Rⁿ, each vector has n components.

So, the total number of unknowns is p, while the total number of equations that we have is n.

Hence p≥n for the system of linear equations above to have a non-zero solution.

Psychologists have raised concerns about the accuracy and validity of ____ personality tests, as they are not standardized. This means that the same test administered to two different people can yield different results, making it difficult to interpret. Moreover, results may be inconsistent, meaning the same test administered at different times could produce different results. This lack of consistency can lead to inaccurate interpretations and can render the tests less useful. Furthermore, there is a lack of standardization of criteria and methodologies used to evaluate personality tests, which could lead to misinterpretations of results.
In order to address these issues, it is important to use standardized personality tests, which are tested and validated to ensure consistent and accurate results. This will ensure that the tests yield consistent results and can be interpreted accurately.

Additionally, researchers must adhere to established guidelines and criteria to ensure that the results are reliable and valid. This will enable professionals to confidently use the tests and make accurate interpretations of the results.
