The length of a clothe is 9m, it was increased to 12m, what is the percent of change.

Using the formula of slope of a line, the slope in the graph is -2/3

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by the formula

m = y₂ - y₁ / x₂ - x₁

Taking two coordinate from the line;

Substituting the values into the formula below

m = y₂ - y₁ / x₂ - x₁

m = 0 - 4 / 6 - 0

m = -4 / 6

m = -2/3

The slope is -2/3

The horizontal asymptote of function f(x) is y=6.5, which is a straight line, which means that even if time is infinite, the pH of the mouth will not rise above 6.5, which is the normal pH of the mouth.

A function's horizontal asymptote is a horizontal line with which the function's graph appears to coincide but does not actually coincide. The horizontal asymptote is used to determine the behavior of the function.

When either lim x f(x) = k or lim x - f(x) = k, the horizontal asymptote of a function y = f(x) is a line y = k. . It is commonly abbreviated as HA. In this case, k is a real number that the function approaches when x is extremely large or extremely small.However, the maximum number of asymptotes that a function can have is 2.

Given,

[tex]f(x)=\frac{6.5x^2-89.4x+3734}{x^2+576}[/tex]

The horizontal asymptote of the function f(x) can be determined by

[tex]y=\lim_{x \to \infty} f(x)\\\\=\lim_{x \to \infty}\frac{6.5x^2-89.4x+3734}{x^2+576}\\\\=\lim_{x \to \infty}\frac{x^2(6.5-\frac{89.4}{x}+\frac{3734}{x^2})}{x^2(1+\frac{576}{x^2})}\\\\=\lim_{x \to \infty}\frac{(6.5-\frac{89.4}{x}+\frac{3734}{x^2})}{(1+\frac{576}{x^2})}\\\\=\frac{(6.5-\frac{89.4}{ \infty}+\frac{3734}{ \infty})}{(1+\frac{576}{ \infty})}\\\\=\frac{6.5-0+0}{1+0}\\\\=\frac{6.5}{1}=6.5[/tex]

Thus, the horizontal asymptote of function f(x) is y=6.5 which is straight line which means even the time reaches infinity the pH of mouth will not increase more than 6.5, which is the normal pH of mouth.

The values of unknown measures are m∠C'B'D' = 95°,  CQ = 6 and B'D' = 11

We are given that triangle BCD was dilated using the rule d subscript q, one-half.

Since the sum of the measure of all the angles in a triangle is 180°.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (by dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

[tex]\frac{B C}{B^{\prime} C^{\prime}}=\frac{B D}{B^{\prime} D^{\prime}}=\frac{36}{18}=2[/tex]

[tex]B^{\prime} D^{\prime}=\frac{1}{2} B D[/tex]

= 1/2(22)

=11

The dilated triangles are similar to each other.

Hence,  we can say that ΔC'P'Q ∼ ΔCPQ,

[tex]\frac{C^{\prime} Q}{C Q}=\frac{C^{\prime} D^{\prime}}{C D}=\frac{D^{\prime} Q}{P Q}[/tex]

C Q= C'Q x  [tex]\frac{C D}{C^{\prime} D^{\prime}}[/tex]

=C'Q x [tex]\frac{B C}{B^{\prime} C^{\prime}}[/tex]

Step-by-step explanation:

The formula used to gain information about an individual data value when the variable is normally distributes is,  Z = (X - μ)/σ.

What is standard normal distribution?

The standard normal distribution, also known as the z-distribution, is a unique type of normal distribution in which the mean and standard deviation are both equal to 1.

Any normal distribution's values can be transformed into z scores to standardize it.

Z scores indicate the number of standard deviations away from the mean that each value represents.

The Z score is determined by the number of standard deviations above or below the mean for the standard normal distribution.

When a variable (let's say X) is normally distributed, then to get insights from its distribution, we transform it (i.e. X) into standardized variable (which constitutes "Standard" Normal Distribution).

Standardized variable, Z, is given by  (X - μ)/σ

Hence, option B is correct answer.  Z = (X - μ)/σ.

Step-by-step explanation:

You want the probability of rolling a 6-sided die 3 times with the sequential outcomes 3, not 3, even number.

The probability of any given sequence of outcomes is the product of the probabilities of the outcomes individually. (We assume independence.)

  P(3) = 1/6

  P(not 3) = 1 -P(3) = 5/6

  P(even) = 1/2

Then the probability of the given sequence is ...

  P(3, 3', even) = (1/6)(5/6)(1/2) = 5/72

The probability of the given sequence is 5/72.

The popcorn box in a shape of a rectangular prism will thus have a length of 0.3 inches in inches.

A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism.

A rectangular prism also refers to a cuboid.

A cuboid and a rectangular prism have the same cross-section.

Quadrilaterals make up its faces.

So, a popcorn box's volume is modeled by Gabriel as a right rectangular prism, and a full box can store 74 cubic inches of popcorn.

Its height is 77 in, and its breadth is 3 1/2 in.

Then, the prism's width will be:

W =  3 + 1/2

W = 7/2

Consequently, the popcorn box's length in inches will be:

V = LWH

74 = L * 7/2 * 77

L = 0.2745 = 0.3

Therefore, the popcorn box in a shape of a rectangular prism will thus have a length of 0.3 inches in inches.

Based on the definition of similar quadrilaterals, the measure of side MN is: 14.1 units.

If two quadrilaterals are similar to each other, then the measure of their corresponding sides will have a ratio that is equal. This means they will have proportional side measures.

Since we are told that quadrilaterals GHIJ and KLMN are similar to each other, then their corresponding sides will have measures that are proportional to each other.

Therefore:

IJ/MN = GJ/KN

IJ = 35

MN = ?

GJ = 52

KN = 21

Substitute:

35/MN = 52/21

Cross multiply:

MN(52) = (35)(21)

MN(52) = 735

MN = 735/52

These expressions are all equivalent to 12x - 6 because they all have the same value, regardless of the value of x. This is because the terms on the right side of the equation cancel out, leaving only the constant value on the left side. For example, in the first expression, 6(2x - 1), the 2x and -1 terms cancel out, leaving only 6. This is the same for the other expressions listed above.

Note that in each of the above expressions, the value of 12x - 6 is preserved, but the terms and the order of operations may be different. For example, in the second expression, the subtraction has been expressed as addition with a negative number, and in the fourth and sixth expressions, the subtraction has been expressed as multiplication with a fraction.

Answer:

Step-by-step explanation:

You want to select the scatter plot with strong positive correlation.

Correlation is a measure of how well one variable's values track the values of another variable. Perfectly correlated variables will have a scatter plot that is a straight line. The sign of the correlation (positive, negative) matches the sign of the slope of the line.

The less correlated values are, the more their scatter plot looks like a random placement of points. When there is no correlation at all, knowing the value of one of the variables gives no clue about the value of the other one.

Computed values of correlation range from -1 to +1.

When the plot begins to resemble a line with positive slope, the variables plotted in the scatter plot have strong positive correlation. That is shown in the attached scatter plot.

The best interpretation of this result is a. We can not conclude whether earning more money causes more recycling among U.S. adults because this type of study does not allow us to infer causation.

Causation cannot be deduced from the study's design (CORRELATION ≠ CAUSATION). The strength and direction of a relationship between two or more variables are described by the statistical measure of correlation, which is given as a number.

However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other.

There is a causal relationship between the two occurrences, which means that causation shows that one event is the outcome of the occurrence of the other event. This concept is also known as cause and effect.

The adage "correlation does not imply causation" relates to the difficulty of establishing a cause-and-effect connection between two variables or events based merely on the observation of their association or correlation.
