The fundamental question addressed by the correlational method is whether two or more variables are related in some systematic way. So the correct option is D.

Correlational method is a research technique used to explore the relationship between two or more variables. In this method, researchers collect data on the variables of interest and analyze their patterns of association. The fundamental question addressed by the correlational method is whether two or more variables are related in some systematic way. This means that researchers are interested in exploring whether changes in one variable are associated with changes in another variable.

For instance, a researcher may be interested in exploring the relationship between stress and job performance. The researcher may collect data on the levels of stress and job performance in a sample of employees and then use statistical analysis to determine if there is a systematic relationship between the two variables. If the results show that higher levels of stress are associated with lower levels of job performance, then the researcher can conclude that there is a negative correlation between the two variables.

It is important to note that correlation does not imply causation. While a correlation between two variables indicates that they are related, it does not necessarily mean that changes in one variable are causing changes in the other variable. Therefore, researchers must be cautious when interpreting correlational data and should consider other factors that may be influencing the relationship between variables.

Therefore, the fundamental question addressed by the correlational method is whether two or more variables are related in some systematic way, and researchers must be cautious when interpreting correlational data and should consider other factors that may be influencing the relationship between variables.

About 75% of the students' scores exceeded the score mentioned in the boxplot.

In a boxplot, the box represents the interquartile range (IQR), which contains the middle 50% of the data. The lower whisker extends to the minimum value within 1.5 times the IQR below the first quartile (Q1), and the upper whisker extends to the maximum value within 1.5 times the IQR above the third quartile (Q3).

Since the boxplot does not provide specific numerical values, we can infer that the mentioned score lies within the upper whisker, which represents the top 25% of the data. Therefore, about 75% of the students' scores exceeded this score.

It's important to note that without the actual values or specific percentiles, we can only estimate the percentage based on the visual representation of the boxplot. The exact percentage may vary depending on the scale and distribution of the data. To obtain a more precise estimate, additional information such as the quartiles or a histogram of the scores would be needed.

Answer:

10.2

Step-by-step explanation:

100/9.8 = 10.2

Let's solve your system by substitution.

4x−4y=8 and 5x−3y=18

Step: Solve 4x−4y=8 for x:

4x − 4y = 8

4x − 4y + 4y = 8 + 4y (Add 4y to both sides)

4x = 4y + 8

\(\frac{4x}{4} = \frac{4y + 8}{4}\)

x = y + 2

Step: Substitute y + 2 for x in 5x − 3y = 18:

5x − 3y = 18

5(y+2) − 3y = 18

2y + 10 = 18  (Simplify both sides of the equation)

2y + 10 + (−10) = 18 + (−10)  (Add -10 to both sides)

2y = 8

y = 4

Step: Substitute 4 for y in x = y + 2:

x = y + 2

x=4+2

x=6  (Simplify both sides of the equation)

Answer:

x = 6 and y =4

Step-by-step explanation:

The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

Function is a type of relation, or rule, that maps one input to specific single output.

The function f(x) is defined as:

→ f(x)= 80x* 2 + 640 - 400x - 52

We need the degree and the leading coefficient to determine the behavior.

Since our leading coefficients has a leading even degree of 5, and a positive number,

The function will Rises to the left and falls to the right.

The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

Answer:

x = -1

Step-by-step explanation:

Given equation:

\(\log_5(24-x)+\log_5(-x)=2\)

\(\textsf{Apply the log Product law}: \quad \log_ax + \log_ay=\log_axy\)

\(\implies \log_5[-x(24-x)]=2\)

\(\implies \log_5(x^2-24x)=2\)

\(\textsf{Apply the log law}: \quad \log_ab=c \iff a^c=b\)

\(\implies 5^2=x^2-24x\)

Simplify:

\(\implies x^2-24x-25=0\)

Factor the quadratic equation:

\(\implies x^2+x-25x-25=0\)

\(\implies x(x+1)-25(x+1)=0\)

\(\implies (x-25)(x+1)=0\)

Apply the zero product property:

\(\implies x-25=0 \implies x=25\)

\(\implies x+1=0 \implies x=-1\)

As logs of negative numbers cannot be taken, x = -1 is the only valid solution.

Check by substituting x = -1 into the original equation:

\(\implies \log_5(24-(-1))+\log_5(-(-1)\)

\(\implies \log_5(25)+\log_5(1)\)

\(\implies \log_5(5^2)+0\)

\(\implies 2\log_5(5)\)

\(\implies 2(1)\)

\(\implies 2\)

Hence, the solution is:

\(\boxed{ x = -1}\)

The simplified product of the given expression is, 12n + 8.

What is simplified form of the expression?

If a fraction's top and bottom have only the number one in common, then it is expressed in its simplest form. The top and bottom cannot be divided further and remain entire numbers, in other words. The phrase "lowest terms" is another name for the simplest form.

Given:

Start fraction 8 over 6 n minus 4 end fraction times start fraction 9 n squared minus 4 over 1 end fraction

Convert it into mathematical expression,

\(\frac{8}{6n-4}(\frac{9n^2-4}{1})\)

Simplify,

\(=\frac{2(4)}{2(3n-2)}(\frac{9n^2-4}{1})\\= \frac{4}{3n-2}(9n^2-4) \\\)

Here,

\(9n^2-4 = (3n-2)(3n+2)\\\)

⇒

\(=\frac{4}{(3n-2)}(3n-2)(3n+2) \\=4(3n+2)\\=12n+8\)

Hence, the simplified form of the given expression is 12n + 8.

The computation is that the width is 21.5 feet and the height is 12.5.

Let the height = h

Let the width = (3 × h) - 16 = 3h - 16

Therefore, the dimensions will be:

h + 3h - 16 = 34

4h = 34 + 16

4h = 50

Divide

h = 50/4

h = 12.5

Therefore width = 3h - 16 = 3(12.5) - 16

= 37.5 - 16

= 21.5

The width is 21.5 feet and the height is 12.5.

Answer: This is a periodic relation.

Step-by-step explanation:

This is a periodic relation, that can be modeled with a sinusoidal relation, that relates the height as a function of time.

Then we can write this as h(t) = A*sin(C*t + F) + B

Where A is the amplitude, C is a constant that depends on the period, F is a phase shift, and B is the midpoint of the function.

2*A is the distance between the maximum height and the minimum height.

B is the middle height of the Femis Wheel.
