Out of the following, the statement is It generates testable hypotheses, is supported by a large body of evidence, and is broad in scope is true of a scientific theory.
A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. A scientific theory is not just an idea or speculation. It is a systematic way of organizing and interpreting observations that are based on facts and evidence. It is also open to being tested and disproved if new evidence arises.
A scientific theory must be supported by a large body of evidence from multiple sources to be considered valid. Furthermore, a scientific theory must be broad in scope and explain a wide range of phenomena. It must also generate testable hypotheses that can be tested and verified through experimentation and observation.
A scientific theory is not accepted until it is thoroughly tested and confirmed through numerous experiments and observations. Therefore, it is not accepted after the person who formulated it has died.

Suppose you are assigned the number 1, and the other students in your statistics class call out consecutive numbers until each person in the class has his or her own number.
Explain how you could get a random sample of four students from your statistics class. (Select all that apply.)
A. Randomly choose four of the students that are sitting in the back row.
B. Use a computer or random-number table to randomly select four students after numbers are assigned.
C. Randomly choose four of the first students that walk into the classroom.
D. Randomly choose four of the tallest students in the classroom.
E. Randomly choose four of the last students that walk into the classroom.
The most suitable method to obtain a random sample of four students from the statistics class would be to use a computer or random-number table to randomly select four students after numbers are assigned.
This method ensures that every student has an equal chance of being selected and that the sample is truly random. This is the only method that guarantees that the sample is random and representative of the entire class.
The other methods listed (A, C, D, and E) do not ensure randomness, as they are based on non-random criteria (such as seating arrangement, height, or time of arrival). These methods might introduce bias into the sample and lead to incorrect conclusions about the population.
Hence, the correct answer is B.

The rule for divisibility by 9 is similar to divisibility rule for 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.
What is divisibility?the capacity of being divided. Math. the capacity of being evenly divided, without remainder.
Divisibility rules or Divisibility tests have been mentioned to make the division procedure easier and quicker. If students learn the division rules in Math's or the divisibility tests for 1 to 20, they can solve the problems in a better way. For example, divisibility rules for 13 help us to know which numbers are completely divided by 13. Some numbers like 2, 3, 4, 5 have rules which can be understood easily. But rules for 7, 11, 13, are a little complex and need to be understood in-depth.
Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.
Example: 10, 20, 30, 1000, 5000, 60000, etc.
For any given number, to check if it is divisible by 13, we have to add four times of the last digit of the number to the remaining number and repeat the process until you get a two-digit number. Now check if that two-digit number is divisible by 13 or not. If it is divisible, then the given number is divisible by 13.
For example: 2795 → 279 + (5 x 4)
→ 279 + (20)
→ 299
→ 29 + (9 x 4)
→ 29 + 36
→65

It is reported that the wild tiger population has declined by 97%
over the last 20 years.
There are now 3200 tigers left in the wild.
To the nearest thousand, how many wild tigers were there 20 years ago?
The nearest thousand, there were an estimated 116,000 wild tigers 20 years ago.
Determine Percentage decrease theory.The percentage decrease theory suggests that a decrease in the price of a product or service will lead to an increase in demand for that product or service.
This theory is based on the idea that consumers are more likely to buy a product or service if its price is lower. This theory can be applied to both new and existing products or services.
For example, a retailer may decide to decrease the price of a product in order to attract more customers and increase sales. Similarly, a company may choose to reduce the cost of a service in order to make it more attractive to potential customers.
This question is using the percentage decrease theory. According to this theory,
you can calculate the percentage decrease by subtracting the current value from the original value and then dividing by the original value.
Step 1: Subtract the current number of wild tigers (3200) from the original number of wild tigers (20 years ago).
Original - Current = Change
120,000 - 3200 = 116,800
Step 2: Divide the change (116,800) by the original number of wild tigers (120,000)
Change / Original = Percentage Change
116,800 / 120,000 = 97%
Step 3: Multiply the percentage change (97%) by the original number of wild tigers (120,000)
Percentage Change x Original = Estimated Original
97% x 120,000 = 116,400
Therefore, to the nearest thousand, there were an estimated 116,000 wild tigers 20 years ago.

If f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.
What is a function?
A function is a mathematical object that assigns exactly one output to each input of a specified type. In other words, a function is a rule that takes in certain inputs (or "arguments") and produces a unique output. The inputs to a function are called the domain, while the set of possible outputs is called the range.
The given functions are f(x) = 3x and g(x)=x-2.
To find f(g(4)), we first need to evaluate g(4). The function g is defined as g(x) = x - 2, so g(4) = 4 - 2 = 2.
Next, we need to evaluate f(2), where f is defined as f(x) = 3x. So, f(2) = 3 * 2 = 6.
Therefore, f(g(4)) = f(2) = 6.
Hence, if f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.

How to determine the value of csc(A)From the question, we have the following parameters that can be used in our computation:
sec(A) = 7/3
Take the inverse of both sides
cos(A) = 3/7
Using the following trigonometry identity, we have
sin²(A) + cos²(A) = 1
Substitute the known values in the above equation, so, we have the following representation
sin²(A) + (3/7)² = 1

sin²(A) = 40/49
Take the square roots
sin(A) = ±√(40/49)
The angle is in quadrant II
So, we have
sin(A) = √(40/49)
Take the inverse
csc(A) = √(49/40)
So, we have

On solving the system of linear equations 3x + 3y = 45 and x + 2y = 24, the cost for each shirt is obtained as $6, and cost for each pair of pants is obtained as $9.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
Let the cost of shirts be x and the cost of pair of pants be y.
The number of shirts bought by person A = 3
The number of pair of pants bought by person B = 3
The total cost for person A = $45
The equation for person A is -
3x + 3y = 45....(1)
The number of shirts bought by person B = 1
The number of pair of pants bought by person B = 2
The total cost for person B = $24
The equation for person B is -
x + 2y = 24....(2)
Multiply equation (2) by 3 -
3(x + 2y) = 24 × 3
3x + 6y = 72....(3)
Subtraction equation (1) from equation (3) -
3x + 6y - (3x + 3y) = 72 - 45
3x + 6y - 3x - 3y = 27
3y = 27
y = 9
Substitute the value of y in equation (2) -
x + 2(9) = 24
x + 18 = 24
x = 24 - 18
x = 6
Therefore, the cost of shirts and pants is x = 6 and y = 9 respectively.

An equation that represents the linear function shown in the table or mapping diagram is y = -x/4 - 3.
How to write an equation that represents the linear function?In order to write an equation that represents the linear function, we would use the point-slope form. Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.Next, we would determine the linear function representing the line which passes through the data points (-4, 6) and (8, 3) by using the point-slope form as follows:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 6 = (3 - 6)/(8 - (-4))(x - (-4))
y - 6 = (3 - 6)/(8 + 4)(x + 4)

The dating web site Oollama.com requires its users to create pro les based on a survey in which they rate their interest (on a scale from 0 to 3) in positive categories: physical fitness, music, spirituality, education, and alcohol consumption.
A new Oollama customer, Erin O'Shaughnessy, has reviewed the pro les of 40 prospective dates and classi ed whether she is interested in learning more about them. Based on Erin's classi cation of these 40 pro les, Oollama has applied a logistic regression to predict Erin's interest in other pro les that she has not yet viewed. The resulting logistic regression model is as follows:
Log odds of Interested = −0.920 + 0.325 × Fitness − 3.611 × Music
+5.535 × Education − 2.927 × Alcohol

Show me how to shade decimal number 0.009 in a base- ten block
To shade decimal number 0.009 in a base-ten block, you would shade one 1/100th block and nine 1/1000th blocks. This can be seen in the image below.
How to shade decimal number 0.009 in a base- ten block?Shading decimal numbers in a base-ten block is a great way to visualize numbers in a concrete way. To shade decimal number 0.009 in a base-ten block, start by breaking down the number into its place values. The number 0.009 is equivalent to 9 thousandths, or 0.001. Begin by drawing a base-ten block with four places on the left and one on the right. The four places on the left are labeled hundredths, tenths, ones, and tens respectively. The one place on the right is labeled tenths. Next, shade in the thousandths place, which is the rightmost place on the base-ten block. This will represent the 9 thousandths from 0.009. The thousandths place should be shaded in with a gray or light color. Finally, the remaining places should be left blank, since 0.009 does not have any values in the hundredths, tenths, or ones places. The tenths place should also be left blank. In this way, decimal number 0.009 can be easily visualized in a base-ten block. The thousandths place is shaded in, while the remaining places are left blank.1 tenth | 0 hundredths | 0 thousandths | 9 ten-thousandths
____ | ____ | ____ | ____
We can shade 0.009 in a base-ten block as follows:100th | 0
10th | 0

Need help with question attached below in an image.
We can apply the order of four transformations to the graph of f(x) in order to sketch the graph of g(x): A 3-unit horizontal shift to the left : The graph becomes f(x-3 ) as a result, with a vertical asymptote at x = 0 rather than x = 3.
A ( -2 ) stretch in the vertical direction: The graph is now -2f(x-3), with a slope of -2 for x greater than 3 and 2 for x less than 3.An observation regarding the x-axis: The graph is now -2|f(x-3)|, which is the x-axis-reflecting graph of f(x-3) as a result of this change.A shift up one unit in the vertical: The result of this transformation is the final graph of g(x) = -2|x-3|+1, which is -2|f(x-3)|+1.2. To move from f(x) to g(x), four transformations are used:
A three-unit horizontal shift to the left: The graph thus shifts by a factor of -2 three units in the direction of the left A vertical stretch.
How does one plot a graph?You must first define the function and its domain before you can plot its graph. We can begin by sketching the piecewise linear graph of f(x) = |x|, which has a slope of 1 for x greater than 0 and -1 for x less than 0 in order to sketch the graph of g(x) = -2|x-3|+1. The vertical asymptote is shown by the x axis. For all real numbers, the definition of the f(x) graph exists.
