Subtraction property of equality is B, -4.

What is subtraction property?

The Subtraction Property of Equality states that if two expressions are equal, then the same expression minus any number will also be equal. In other words, if a = b, then a - c = b - c. This property is important in algebra, as it allows us to solve equations by subtracting the same number from both sides. This property is also known as the Subtraction Property of Equality or the Subtraction Property of Equality of Two Values. It is an important concept that allows us to solve equations, and it is used in all levels of mathematics.

After solving the equation, the time in minutes Bob rides the scooter will be equal to 97 minutes.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

Total price paid to start the scooter = $3

Price of ride per minute = 11 cents

1 dollar  = 100 cents

So, 11 cents = 11/100 = $0.11 per minute

Then, the equation will be,

$3 + $0.11(x) = $13.67

Here, x is the total number of minutes.

0.11x = 13.67 - 3

0.11x = 10.67

3 (for the box), p=1

Step-by-step explanation:

Since they want you to follow the instructions, divide by 2 to get (5p-2p) alone.

6p/2 = 3p (exactly like 6/2)

You will get 3p=5-2p

To solve the rest of the equation, add 2p to both sides (once you add 2p to the left side, it gets rid of it on the right side by canceling it out)

3p=5-2p

+2p  +2p

5p=5

Divide 5p by 5 to get p by itself.

5p/5 = 5/5

That is p = 1

Information can not be determined by histogram.

What is histogram?

A histogram is an approximation of the distribution of numerical data. This term was first introduced by Karl Pearson. The first step in creating a histogram is to "bin" (or "bucket") the range of values. That is, divide the entire range of values ​​into a series of intervals and count the number of values. At each interval fall. Bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins (intervals) must be contiguous and often (but not necessarily) the same size.

If the bins are the same size, bars are drawn across the bins, with heights proportional to frequencies (number of cases in each bin). Histograms can also be normalized to display "relative" counts, which indicate the proportion of cases falling into each of multiple categories with sum of heights equal to 1.

Let x be the coefficient of y^2 in the expression 2x^2y+10xy^2-5y^2. So x=5.

A coefficient is a multiplicative factor in a polynomial, series, or expression in mathematics. It is typically a number, although it can also be any expression (including variables such as a, b and c). They may also be referred to as parameters if the coefficients are variables in and of themselves.

As an illustration, 6z stands for 6 times z. Since z is a variable, 6 is a coefficient. For variables without a value, the coefficient is 1.

The given algebraic expression is 2yx^2+10xy^2-5y^2.

To rewrite an expression in equivalent form, you can use the distributive property, combine like terms, apply the commutative property, or use identities to simplify and rearrange the expression.

The distributive property states that multiplying a term and a sum of two or more terms is the same as multiplying each individual term and then adding the products together. It can be used to simplify expressions by breaking down larger terms into smaller ones. For example, 8(x + 2) can be rewritten as 8x + 16.Combining like terms is another way to rewrite expressions in equivalent form. This involves adding (or subtracting) two or more terms with the same variables. For example, 5x + 3x can be rewritten as 8x.The commutative property states that changing the order of two numbers or variables does not change their value. This can be used to rearrange expressions in equivalent forms. For example, 5x + 2y can be rewritten as 2y + 5x.Finally, identities are equations that are always true. They can be used to simplify and rearrange expressions in equivalent form. For example, (x + y)2 can be rewritten as x2 + 2xy + y2 using the identity (x + y)2 = x2 + 2xy + y2.

If any two angles and side included between the angles of one triangle are equivalent to the corresponding two angles and side included between the angles of the second triangle, then the two triangles are said to be congruent.

There are 5 main rules of congruency for triangles:

Three Ways To Prove Triangles Congruent:

SSS (Side-Side-Side) Postulate: If there exists a correspondence between the vertices of two triangles such that three sides of one triangle are congruent to the corresponding sides of the other triangle, the two triangles are congruent.

SAS (Side-Angle-Side) Postulate: If there exists a correspondence between the vertices of two triangles such that the two sides and the included angle of one triangle are congruent to the corresponding parts of the other triangle, the two triangles are congruent.

ASA (Angle-Angle-Side)Postulate: If there exits a correspondence between the vertices of two triangles such that two angles and the included side of one triangle are congruent to the corresponding parts of the other triangle, the two triangles are congruent.

By using these rules, If two angles and one side of a triangle are respectively equal to two angles and the matching side of another triangle, then the two triangles are congruent.

A function can have an asymptote if it approaches a horizontal or vertical line but never touches it. There are several types of functions that can have asymptotes, including rational functions, exponential functions, and logarithmic functions.

A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.

There is no function that is always discontinuous. A function is either continuous or discontinuous at a particular point, but it is not necessarily either one at all points.

For example, the function f(x) = x^2 is continuous at all points, but the function g(x) = |x| is discontinuous at x=0.

On the other hand, there are functions that are discontinuous at an infinite number of points, such as the Dirichlet function, which is defined as follows:

f(x) = { 1 if x is irrational

{ 0 if x is rational

This function is discontinuous at all rational points, but it is continuous at all irrational points

Step-by-step explanation:

The correlation coefficient is a numerical measure of the strength of the linear relationship between two variables. It ranges from 0 to 1, with 0 indicating no linear relationship, and 1 indicating a perfect linear relationship. A value of 0.5 or higher is considered a strong correlation.

The correlation coefficient is calculated by taking the covariance between two variables and dividing it by the product of the standard deviations of the two variables. The formula is as follows:

r = covariance(x,y) / (stdDeviation(x) * stdDeviation(y))

The correlation coefficient is a statistical measure used to quantify the strength of the linear relationship between two variables. It takes a value between 0 and 1, with 0 indicating no linear relationship, and 1 indicating a perfect linear relationship. The correlation coefficient is calculated by taking the covariance between the two variables and dividing it by the product of their standard deviations. A negative correlation coefficient means that as one variable increases, the other decreases. A value of 0.5 or higher is considered a strong correlation. The correlation coefficient can be used to determine the strength of the relationships between variables, whether they are linear or non-linear. It is an important tool for data analysis and can help to identify relationships between different variables.

Answer: One solution

Step-by-step explanation:

A regression table mainly shows us that what the coefficients values are, and whether each coefficient is significant (likely to be different from from 0) .

A regression table is a statistical technique that describes how strongly a dependent variable and one or more independent variables are correlated (s). A field or variable you are attempting to predict or comprehend could be a dependent variable.

Regression allows researchers to predict or explain the variation in one variable based on another variable. The variable that researchers are trying to explain or predict is called the response variable. It is also sometimes called the dependent variable because it depends on another variable.

In statistics, regression is a technique that can be used to analyze the relationship between predictor variables and a response variable. When you use software (like R, SAS, SPSS, etc.) to perform a regression analysis, you will receive a regression table as output that summarize the results of the regression.

A regression table primarily reveals the values of the coefficients as well as the significance of each coefficient (how likely it is that it will depart from 0).
