Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

Front

What does it mean when two variables have a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also increases.

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, where each pair consists of an input (x) and an output (y).

Front

What is a function?

Back

A function is a special type of relation where each input (x) is associated with exactly one output (y).

Front

How do you determine the domain of a function?

Back

The domain of a function is the set of all possible input values (x) that the function can accept.

Front

How do you determine the range of a function?

Back

The range of a function is the set of all possible output values (y) that the function can produce.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

How do you calculate the probability of two independent events occurring?

Back

To calculate the probability of two independent events occurring, multiply the probability of the first event by the probability of the second event.
