Sampling is indeed the process of selecting survey respondents or research participants. This statement is true.

Sampling allows researchers to collect data from a smaller, representative group, rather than attempting to gather information from an entire population. This makes the research process more efficient, cost-effective, and manageable. There are various sampling methods, such as random sampling, stratified sampling, and convenience sampling, each with its own advantages and disadvantages depending on the research goals.
A well-designed sampling strategy ensures that the sample accurately reflects the larger population, allowing for generalizable results and meaningful conclusions. It is crucial to consider factors such as sample size and selection bias when designing a research study, as these factors can significantly impact the validity and reliability of the findings. By carefully selecting a representative sample, researchers can increase the likelihood that their results will be applicable to the broader population of interest.
In conclusion, the statement that sampling is the process of selecting survey respondents or research participants is true. This technique is essential in many research scenarios as it enables researchers to gather valuable data and insights from a smaller, manageable group that accurately represents the larger population. Choosing the appropriate sampling method and considering factors such as sample size and selection bias are crucial steps in ensuring the validity and generalizability of the study's findings.

Answer:

  38.5°

Step-by-step explanation:

A triangle solver can give an answer easily. The angle is 38.5°.

__

The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.

  C = arccos((a² +b² -c²)/(2ab))

Here, we have a=35, b=48, c=30, so the angle is ...

  C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°

The angle the cable makes with the pole is about 38.5°.

Step-by-step explanation:

Step-by-step explanation:

Because vertical angles have equal measure, angle CPB = 90 degrees. By extension, angle CPQ + angle QPB = 90 degrees

So 2x+4x+12=90

6x+12=90

6x=78

x=13

It's not either of the first two, because they both have intervals with x < 0 and that first piece is only x < -4.

It's also not the bottom choice, because the middle piece is horizontal, not with a slope of 4.

That means is option #3.

When rotating a point 90 degrees counterclockwise about the origin our point T(x,y) becomes T'(-y,x).

Answer:

a) AB = XY

BC = YZ

CA = XZ

b) <A = <X

c) <X= 50°

Since <A= 50° and <A = <X

d) Measure of <C will be

<C + <A = 180°

<C + 50° = 180°

<C = 180° - 50°

<C = 130°

Answer:

Multiply the first equation by 5 and the second equation by 2. Then add.

Multiply the first equation by 2 and the second equation by 5, then subtract.

Step-by-step explanation:

Given

\(- 2x + 5y = -15\)

\(5x + 2y = -6\)

Required

Steps to solve using elimination method

From the list of given options, option 2 and 3 are correct

This is shown below

Option 2

Multiply the first equation by 5

\(5(- 2x + 5y = -15)\)

\(-10x + 25y = -75\)

Multiply the second equation by 2.

\(2(5x + 2y = -6)\)

\(10x + 4y = -12\)

Add

\((-10x + 25y = -75) + (10x + 4y = -12)\)

\(-10x + 10x + 25y +4y = -75 - 12\)

\(29y = -87\)

Notice that x has been eliminated

Option 3

Multiply the first equation by 2

\(2(- 2x + 5y = -15)\)

\(-4x + 10y = -30\)

Multiply the second equation by 5

\(5(5x + 2y = -6)\)

\(25x + 10y = -30\)

Subtract.

\((-4x + 10y = -30) - (25x + 10y = -30)\)

\(-4x + 25x + 10y - 10y= -30 +30\)

\(21x = 0\)

The number of orderings of the colored houses is possible in 3 ways

There are 24 possible arrangements for the houses. The number of ways with the blue house next to the yellow house is \($3! \cdot 2!=12$\),

as we can consider the arrangements of B,Y, O, and R.

Thus there are \($24-12$\) arrangements with the blue and yellow houses non-adjacent.

Exactly half of these have the blue house before the yellow house by symmetry, and exactly half of those 6 arrangements have the orange house before the red house (also by symmetry), so our answer is

To find the value of sin theta, we are given that theta is in the first quadrant and tan theta = 15/4. We will use the Pythagorean identity to find the value of sin theta. the value of sin theta is:sin θ = 15/17Answer: sin θ = 15/17

Pythagorean identity: sin²θ + cos²θ = 1We know that tan theta = 15/4, which means that: tan θ = sin θ / cos θ15/4 = sin θ / cos θRearranging the above equation, we get: sin θ = (15/4) cos θ ... (1)Now, we will use the Pythagorean identity to find the value of cos θ.cos²θ + sin²θ = 1Using the above identity, we can write: cos θ = √[1 - sin²θ]Substituting the value of cos θ in equation (1), we get:sin θ = (15/4) √[1 - sin²θ]Squaring both sides, we get: sin²θ = (225/16)(1 - sin²θ)Solving for sin²θ, we get: sin²θ + (225/16) sin²θ = 225/16(1 - sin²θ)sin²θ + (225/16) sin²θ = (225/16) - (225/16) sin²θ(289/16) sin²θ = 225/16sin²θ = (225/16) / (289/16)sin²θ = 225/289Taking the square root of both sides, we get:sin θ = ± 15/17Since theta is in the first quadrant, sin θ is positive.

In Friedman's test for a randomized block design, the correct alternative hypothesis is a. ha: not all the sample means are equal

The Friedman's test is a non-parametric statistical test used in randomised block designs, where the same individuals are evaluated under various circumstances or at various times, to compare three or more similar groups or treatments. In Friedman's test, the alternative hypothesis (Ha) argues that certain sample means are not equal to all other sample means,

Whereas in the test, null hypothesis (H0) states that all sample means are equal. In other words, the alternative hypothesis takes into account the likelihood of such differences and Friedman's test is used to assess if there are any statistically significant variations in the mean rankings of the groups or treatments.

The statement "Conditional probability does not rely on another event happening" false because conditional probability relies on another event happening

Now, let's address the statement "Conditional probability does not rely on another event happening. True or False?" The statement is False. Conditional probability by definition relies on another event happening, which is the event that the probability is conditioned on. In the example above, event B is a prerequisite for calculating the probability of event A, so the occurrence of event B is necessary for the calculation of the conditional probability P(A|B).

To explain this concept mathematically, let's use the formula for conditional probability:

P(A|B) = P(A and B) / P(B)

Where P(A and B) is the probability of both events A and B occurring, and P(B) is the probability of event B occurring. This formula shows us that the probability of A occurring given B has occurred is equal to the joint probability of A and B occurring divided by the probability of B occurring.

Answer:

I believe your answer would be y=1.

Step-by-step explanation:

The circle is located with its point on 1 of the x axis, and the cross section would be pulled straight from that term. So the cross section would need to be revolved around y = 1, instead.

This is just my best guess, so I hope it helps!

To get a sphere, we need to do a revolution around the line x = 1.

The line that we must use must be a line that divides the circle in two equal parts, so it must pass through its center.

We know that the center of our circle is the point (1, 0).

With that in mind, the two lines that we know that will divide the circle in two equal parts are:

The opposite side of the right triangle (x) is approximately 6.888 inches long.

To solve this problem, we can use the trigonometric ratio for the sine function, which is opposite/hypotenuse. We have the hypotenuse as 12 inches and the opposite angle as 35 degrees, so we can set up the equation:

sin(35) = opposite/12

To solve for the opposite, we can multiply both sides by 12:

opposite = 12 * sin(35)

sin(35) as approximately 0.574:

opposite = 12 * 0.574

opposite ≈ 6.888

Therefore, the opposite side of the right triangle (x) is approximately 6.888 inches long.
