(A) The lack of any particular intervention or treatment is a distinguishing feature of a quasi-experiment.

Experimental and quasi-experimental studies are characterized by testing an intervention's effects.

If a human subject is included in an intervention, the researcher will randomly assign them to either receive the independent variable, such as a modified diet or nutritional supplement or to the control group.

Putting into practice an intervention without using randomization.

"In that, an independent variable is manipulated, quasi-experimental research is comparable to experimental research.

Because there is either no control group, no random selection, no random assignment, or no active manipulation, it varies from experimental research."

Therefore, (A) the lack of any particular intervention or treatment is a distinguishing feature of a quasi-experiment.

We select every fifth invoice in a file is systematic sampling.

Systematic sampling is a probability sampling technique where researchers choose individuals from the population at predetermined intervals (or k).

This method will provide you with a representative sample that can be utilized to make inferences about your community of interest if the population order is random or random-looking (for example, alphabetical).

This type of sampling is most suitable when we want to conduct a sampling method similar to simple random sampling but the list of population is unknown to us. However, this can also be used when the list of the same is available to us.

Another important condition is the order or the population, i.e. ow it is spread must be random and not in some particular order or sample. Else the result obtained will lose its credibility.

The smallest integer that can possibly be the sum of an infinite geometric series whose first term is 9 is not possible.

An infinite geometric series is a series that continues indefinitely, where each term is found by multiplying the previous term by a constant ratio.

To determine the convergence limit, we must first determine if the series converges. The series converges if the absolute value of the common ratio is less than 1. If the series converges, the sum can be found using the formula:

S = a / (1 - r)

Where S is the sum, a is the first term of the series (9 in this case), and r is the common ratio. For the sum to be an integer, the denominator (1 - r) must equal 1, which means r must equal 0.

This is not possible, as the absolute value of the common ratio must be less than 1 for the series to converge.

Therefore, the sum of the series cannot be an integer.

A histogram would be a better way to represent this data set, as it provides a clear visual representation of the frequency of different values.

A better way to represent the data set would be to use a histogram. A histogram is a graphical representation of a data set that is used to show how frequently certain values occur in the data set. A histogram can be created by first grouping the data into equal intervals, or bins, and then plotting the frequency of each bin on the y-axis of the graph. This allows for easy comparison of the frequency of different values. For example, in the case of the pharmaceutical company’s employee data, one could create a histogram with 5 bins that represent 6-10 months, 11-15 months, 16-20 months, 21-25 months, and 26-30 months. Then, one can plot the number of employees in each bin on the y-axis of the graph. This would provide a clear visual representation of the data set and make it easier to identify any patterns or trends in the data.

The total amount of time Rebecca's family spends at Mount Rushmore is 51 minutes.

Let's call the total amount of time Rebecca's family spends at Mount Rushmore "t".

According to the information given, 13 minutes of that time is spent watching a movie in the visitor center, which is 16% of the total time spent at Mount Rushmore.

This can be expressed as:

13 minutes / t = 16%

To find the total amount of time t, we need to isolate t in the equation. To do this, we can cross-multiply and solve for t:

13 minutes * 100% = 16% * t

13 minutes * 100% / 16% = t

If a bloodstain is 1.5cm wide and 30cm long, then the angle of impact is 30°.

In forensic science, the angle of impact is the angle at which a blood droplet strikes a surface. It has a range of 0 to 90 degrees and is, by definition, an acute (or right) angle.

Police can partially reconstruct a crime scene by connecting the "strings" that lead from the spatter to an origin area and knowing the angle of contact.

If a bloodstain has a tail or pattern, the angle of impact can be used to forecast how the subsequent bloodstain would look.

So, bloodstain pattern analysis examines the patterns of bloodstains found at crime scenes in an effort to piece together the sequence of events that led to the bloodshed.

Mathematically, we will have:

The angle of impact = sin⁻¹ (wide stain/length stain)

The angle of impact = sin⁻¹ (1.5/3.0)

The angle of impact = 30°

Therefore, if a bloodstain is 1.5cm wide and 30cm long, then the angle of impact is 30°.

In a lottery game where a player picks six numbers and repetition is not allowed, the player has a certain number of choices for each number. The number of choices for each number depends on the range of numbers from which the player can pick.

Let's say the range of numbers from which the player can pick is 1 to 49. For the first number, the player has 49 choices, because they can pick any number from 1 to 49. However, once the player has picked their first number, they have 48 choices for their second number, because they cannot pick the same number again. For the third number, the player has 47 choices, for the fourth number, 46 choices, for the fifth number, 45 choices, and for the sixth number, 44 choices.

The total number of different combinations of six numbers that the player can pick is calculated by multiplying the number of choices for each number. This can be written as 49 x 48 x 47 x 46 x 45 x 44. The total number of combinations is 10,068,347,520.

In other words, if a player picks six numbers from a range of 1 to 49, without repetition, the player has 10,068,347,520 different combinations of numbers to pick from.

It's important to understand that repetition is not allowed in this type of lottery game, as it would greatly increase the number of combinations. Allowing repetition would mean that the player could pick the same number multiple times, which would significantly increase the number of combinations and make the game much less challenging.

In conclusion, in a lottery game where a player picks six numbers from a range of 1 to 49, without repetition, the player has 10,068,347,520 different combinations of numbers to choose from. The number of choices decreases with each number picked, as repetition is not allowed, making the game more challenging.

Step-by-step explanation:

less than 85 milligrams per liter.

To find the probability that a water specimen has an alkalinity level of fewer than 85 milligrams per liter, we can use the standard normal distribution and convert the value of 85 milligrams per liter to a standard score (z-score). The z-score can be calculated using the formula:

z = (x - mean) / standard deviation

Where x is the value of interest (85 milligrams per liter), mean is the mean of the distribution (80 milligrams per liter), and the standard deviation is the standard deviation of the distribution (4.2 milligrams per liter).

Plugging in the values, we get:

z = (85 - 80) / 4.2 = 1.19

Next, we can use a standard normal table or calculator to find the probability of getting a value less than the z-score of 1.19. This probability is approximately 0.8707, so there is about an 87.07% chance that a water specimen collected from the river has an alkalinity level of fewer than 85 milligrams per liter.

The probability of a student completing the final examination in less than 65 minutes is 13.45%.

The time it takes to complete a final examination in a particular college course is normally distributed with a mean of 77 minutes and a standard deviation of 12 minutes. This can be expressed mathematically as X~N(77, 12).

The probability of a student completing the final examination in less than 65 minutes can be calculated by using the Z-score formula:

Z = (x - μ) / σ

Where x = 65 minutes, μ = 77 minutes, and σ = 12 minutes.

Plugging these values into the formula, we get:

Z = (65 - 77) / 12 = -1.17

Using a Z-score table, we can find the probability of a student completing the final examination in less than 65 minutes, which is equal to 0.1345, or 13.45%. Therefore, the probability of a student completing the final examination in less than 65 minutes is 13.45%.

Note that as labeled in the attached image:

1) Shapes D and F are similar

2) A and B are NOT similar because they have different ratios of side lengths

3) C and E are NOTE Similar. They are Different Shape.

1) To determine that both shapes are similar, all we need to divide the side lengths of D by two. This gives us:

Breath  - 6/2 = 3

Length - 14/ 7 = 7

Since the Breadth of F is 3ft and it's length 7ft, it means D and F are similar to the ratio of 2:1.

2) If the above logic is applied to A and B, we would see that the side lengths of both shapes have different ratios.

For both of them to be similar, since the breadths - 6/2 = 3 then the length of B ought to be 4ft since 12/4 = 3.
