Front

What does it mean to condense in mathematics?

Back

To condense means to simplify an expression or equation by combining like terms or reducing it to a more compact form.

Front

What is a leading coefficient in a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree in a polynomial. For example, in the polynomial 7x^2 + x^4 - 2 + 22x, the leading coefficient is 1.

Front

Expand the expression \( \log\left(\frac{x}{y}\right) \).

Back

The expansion of \( \log\left(\frac{x}{y}\right) \) is \( \log x - \log y \).

Front

What does it mean for a graph to be right skewed?

Back

A right skewed graph has a longer tail on the right side, indicating that the majority of the data points are concentrated on the left.

Front

What type of data is daily rainfall classified as?

Back

Daily rainfall is classified as continuous data because it can take any value within a range.

Front

Define discrete data with an example.

Back

Discrete data consists of distinct or separate values. For example, the number of students in a class is discrete data.

Front

What is continuous data?

Back

Continuous data can take any value within a given range. For example, height, weight, and temperature are continuous data.

Front

What is the difference between a polynomial and a monomial?

Back

A polynomial is an expression that can have multiple terms, while a monomial has only one term.

Front

How do you identify the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression. For example, in 3x^3 + 2x^2 + 1, the degree is 3.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula \( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \).
