Quantitative variables offer measurable numerical values that can be added to or subtracted from to produce accurate results. Quantitative discrete variables have a finite or countable number of positive values.

Continuous variables are quantitative and have an endless range of uncountable possible values. Discrete and continuous data are both types of quantitative or numerical information. Measurements are often continuous, while counts are typically discrete. Discrete data are counts that can never be more precisely calculated. Usually, this entails integers.

A family's number of children would serve as an illustration. Individuals are complete, indivisible entities, hence this data is discrete. A family does not contain 1.7 or 2.3 children.

The four basic properties of exponents are the negative exponent property, the product of powers property, the quotient of powers property, and the power of a power property.

The properties of exponents are a set of rules that allow us to simplify terms that contain exponents.

Negative exponent property states that when a negative exponent is present, the base and the exponent are switched and the sign of the exponent is changed. For example,  x-2 = 1/x2.

The product of powers property states that when two terms with the same base are multiplied, the exponents are added together. For example, x3 x4 = x7.

The quotient of powers property states that when two terms with the same base are divided, the exponents are subtracted. For example, x6/x2 = x4.

The power of a power property states that when a term with an exponent is raised to another power, the exponents are multiplied. For example, (x3)2 = x6.

These properties can be used to simplify expressions that contain exponents. For example, the expression (−2m−2????4) 3 can be simplified using the power of a power property by multiplying the exponents. The expression simplifies to −2m−6????12.

The point (-5,6), which is (0,0), is √61 units away from the origin.

A pair of numbers called coordinates are used to locate a point or a shape in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane. The term "ordinate" refers to a point's separation from the x-axis when scaled with the y-axis. Coords are the collective noun for the abscissa and ordinate. The study of algebraic equations on graphs is known as coordinate geometry. The plotting of points, lines, and curves on an x and y axis is an illustration of coordinate geometry.

Here,

distance=√(y2²-y1²)+(x2²-x1²)

=√(6²-0²)+((-5)²-0²)

One can solve basic algebraic expressions by following these steps.

Students typically learn to solve basic algebraic expressions by following these steps:

Identify the variable and the coefficient (number in front of the variable) in the expression.

Use the order of operations (PEMDAS) to simplify any arithmetic within the expression.

Use the distributive property to combine like terms.

Isolate the variable on one side of the equation by using inverse operations (such as adding or subtracting the same value from both sides, or dividing or multiplying both sides by the same non-zero value).

Substitute in a value for the variable to find the numerical value of the expression.

It's good to practice with a lot of examples and check the solutions and ask for help if needed.

Example:

Solve for x: 3x + 2 = 12

variable is x, coefficient is 3

nothing to simplify

nothing to combine

subtract 2 from both sides: 3x = 10

divide both sides by 3: x = 10/3 or 3.3333

x = 3.3333

It's important to note that solving algebraic expressions can become more complex as the student progresses, but the basic steps remain the same.

Thus, One can solve basic algebraic expressions by following these steps.

The only solution to an equation 2x² + 8x = x² - 16 is z = -4

Consider given equation.

2x² + 8x = x² - 16

Subtract x² from each side of equation.

2x² + 8x - x² = x² - 16 - x²

x² + 8x = -16

Add 16 to each side of equation.

x² + 8x + 16 = -16 + 16

x² + 8x + 16 = 0

We factorize above quadratic equation.

Therefore , the solution of the given problem of percentage comes out to be she spend $39 on the sandals.

A number or figure that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the "%" symbol used to represent it is often employed. No dimensions exist; the % amount is flat. Percentages are essentially fractions because their numerator is 100. A percent symbol (%) should be placed in front of a number to indicate that it is a percentage. For instance, if you answered correctly 75 out of questions in total on a test, you'd get a 75%.

Here,

Given :

Money = $80

A function is a set of ordered pairs in which for each x value, there is only one y value. A parent function is the simplest form of a function, with the basic form of the equation.

A parent function with an inverse that is also a function must have an equation that is invertible. In other words, the equation must be able to be rearranged so that the y variable is on one side and the x variable is on the other.

For example, let's look at the parent function f(x) = x^2. To find its inverse, we can rearrange the equation to make y the subject: y = x^2. Then, we can take the square root of both sides, giving us x = sqrt(y). This is the equation of the inverse of the parent function, which is also a function. Similarly, the parent function f(x) = ln(x) has an inverse of f-1(x) = e^x. This is also a function, as each x value has only one y value.

Therefore, for a parent function to have an inverse that is a function, the equation must be invertible. This means that the equation must be rearrangeable so that the y variable is on one side and the x variable is on the other.

The percentage of the data that is less than 76.4 will be 50% if scores of an exam follow an approximately bell-shaped distribution with a mean of 76.4 and a standard deviation of 6.1.

To determine by how many standard deviations the raw score is above or below the mean z score used.

z = (x - μ)/σ

x: raw score, σ: standard deviation, μ: mean

For x = 76.4 points:

z = (76.4 - 76.4)/6.1 = 0

Now, the percentage of data is less than 76.4:

P(x < 76.4) = P(z < 0)

The stock market crash of 1929 was caused by a combination of factors, including overvaluation of stocks and economic policies that favored the wealthy.

The effects of the crash were widespread and long-lasting, leading to the Great Depression and causing significant economic and social upheaval.

One of the causes of the stock market crash of 1929 was the overvaluation of stocks, where prices were much higher than the underlying value of the companies. Many investors were buying stocks on margin, which means they were borrowing money to buy stocks, this lead to the overvaluation of stocks. Another cause was the economic policies that favored the wealthy, such as the high tariffs on imported goods and the lack of regulations on the stock market, which allowed for speculation and manipulation.

The effects of the stock market crash of 1929 were far-reaching and long-lasting. One of the most significant effects was the Great Depression, which led to high unemployment, widespread poverty, and significant declines in industrial production and economic activity. The crash also led to a decline in consumer confidence, which further slowed economic growth and led to a decline in consumer spending.
