Correlation may not always indicate causality shown below.

What do you mean by corelation and causation?

We can determine how strongly a pair of variables are linearly associated and change together using the statistical technique of correlation. It only states that there is a relationship; it doesn't explain why or how it came to be. Correlation goes one step farther than causality. It states that any change in one variable's value will result in a change in another variable's value, or that one variable causes the occurrence of another. It also goes by the name "cause and effect."

may not always indicate causality. with a well-known instance.

In New York, ice cream sales and homicide rates are associated (Study)

The frequency of homicides fluctuates along with ice cream sales. Does ice cream consumption result in deaths of people?

No. The mere correlation of two events does not imply causation.

Since correlation does not imply causation in our example, ice cream is not to blame for any fatalities.

There are occasionally some unspoken aspects that are somehow connected. Weather is the underlying factor that drives both ice cream sales and homicide rates, as in our example. The increase in ice cream sales and killings is actually a result of the weather.

Therefore, significant linear correlation does not imply causality.

Answer:

27

Step-by-step explanation:

factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54

factors of 27 = 1, 3, 9, 27

The greatest factor that exactly divides both 54 and 27 is  27 because they both have it as a factor.

Answer: Reflection over x-Axis

Step-by-step explanation:

Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.

Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.

Given the following:

m∠BFC = 75°

m∠GFC = 38°

∠EFB, ∠BFC,  and ∠GFC are angles on a straight line, therefore:

m∠EFB = 180 - m∠BFC - m∠GFC

Plug in the values

m∠EFB = 180 - 75 - 38

m∠EFB = 67°

Find the measure of angle FBC:

Angles FBC and EFB are alternate interior angles, therefore:

m∠FBC = m∠EFB = 67° [alternate interior angles theorem]

m∠FBC = 67°

In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

Step-by-step explanation:

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Graph C represents the equation y = x + 5.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Let the equation be y = x + 5

The values of m = 1 and b = 5

The slope of the line exists the value of [tex]$$m_r$[/tex] and the y-intercept exists the value of b.

Slope: 1 and y-intercept: (0, 5)

Any line can be graphed utilizing two points. Select two x values, and plug them into the equation to estimate the corresponding y values.

Create a table of the x and y values.

Answer:

  x < 4  or  6 < x

Step-by-step explanation:

You want the compound inequality that describes the number line graph with open circles at 4 and 6, and shading everywhere except between them.

The left line segment has all values less than 4 shaded. The corresponding inequality is ...

  x < 4

The right line segment has all values greater than 6 shaded. The corresponding inequality is ...

  x > 6

These do no overlap, so the compound inequality uses "or" to combine them:

  x < 4 or x > 6

__

Additional comment

Sometimes it is helpful to have the relationship between the shading and the limit values a little more obvious in the inequality. That will be the case if you always use left-pointing inequality symbols: < or ≤. By writing the compound inequality as ...

 x < 4 or 6 < x

we see that shading is outside (left or right of) the interval [4, 6].

The symbol without the "or equal to" bar is used when the circle is an open circle. A filled dot would signify the limit value is part of the interval of interest, and the ≤ (or ≥) symbol would be used.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics.

Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it.

A % is a number without dimensions and without a standard measurement.

For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

The value of c is a real solution to the equation [tex]4x^{2}-8x +c[/tex] = 0 is 4

In algebra, a "real solution" is any answer to an equation that is a real number.

There is just one true solution where discriminant b2 - 4ac equals zero. The equation x2 + 2x + 1 = 0 has one solution, x = -1.

Depending on whether the discriminant is positive, zero, or negative, there are many answers to the quadratic equation that has been presented.

A positive discriminant indicates that the quadratic has two distinct real number solutions.

A discriminant of zero indicates that the quadratic equation has a repeating real number solution.

The quadratic equation given is

[tex]4x^{2}-8x +c[/tex] = 0

For real solution

Discriminant = 0

[tex]b^{2}-4ac[/tex] = 0

What is system of equations?

A set of one or more equations involving numerous variables is referred to as a system of equations. The variable mappings that satisfy all component equations are the solutions to systems of equations, or the points where the components of these equations intersect.

Given:

Juan's school is selling tickets to the annual talent show.

On the first day of ticket sales the school sold 6 adult tickets and 3 student tickets for a total of $51.

The school took in $90 on the second day by selling 9 adult tickets and 6 student tickets.

Let A be the number of adult tickets sold.

S be the number of students ticket sold.

⇒ 6A + 3S = $51            ..(1)

9A + 6S = $90              ..(2)

Multiply first equation by (2)

12A + 6S = $102            ..(3)

Subtract equation (2) and (3)

   12A + 6S = $102

-   9A + 6S = $90

________________

   3A        = 12

⇒ A = $4

Plug A = 4 in equation (1)

6(4) + 3S = $51

24 + 3S = $51

3S = $51 - $24

3S = $27

S = $9

Hence,

(A)  The system of equations is,

6A + 3S = $51          

9A + 6S = $90

Answer:

y = 3x + 72

Step-by-step explanation:

To solve for y, we can rearrange the equation to the form y = 3x + b, where b is a constant. To do this, we move the -9y to the left side of the equation and the 3x to the right side, which gives us -9y - 3x = 81. We can then divide both sides by -9, which gives us y = 3x + 72.

The solution of the equation [tex]\rm 9^y = 3*6*27*4*81*2[/tex] will be 5.76.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

[tex]\rm 9^y = 3*6*27*4*81*2[/tex]

Simplify the equation, then the value of the variable 'y' will be given as,

[tex]\rm 9^y = 3*6*27*4*81*2\\\\9^y = 314,928[/tex]

Take log on both sides, then we have

y log 9 = log 314,928

0.9542 y = 5.4782

y = 5.76

The solution of the equation [tex]\rm 9^y = 3*6*27*4*81*2[/tex] will be 5.76.
