What is the distributive property in algebra?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width: Area = length × width.

Front

What is the formula for the probability of an event?

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes: P(E) = Number of favorable outcomes / Total outcomes.

Front

What is a vertical line of symmetry?

Back

A vertical line of symmetry is a line that divides a shape into two mirror-image halves, where one side is a reflection of the other.

Front

How do you calculate the total number of arrangements of 'n' items taken 'r' at a time?

Back

The total number of arrangements (permutations) of 'n' items taken 'r' at a time is given by the formula: P(n, r) = n! / (n - r)!.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

What is a probability distribution?

Back

A probability distribution is a function that describes the likelihood of obtaining the possible values that a random variable can take.

Front

What is the difference between a combination and a permutation?

Back

A combination is a selection of items without regard to the order, while a permutation is a selection of items where the order does matter.

Front

How do you solve for 'x' in a linear equation?

Back

To solve for 'x' in a linear equation, isolate 'x' on one side of the equation using inverse operations.

Front

What is the formula for the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula: Volume = πr²h, where 'r' is the radius and 'h' is the height.
