What is a causal relationship?

Back

A causal relationship indicates that one event (the cause) directly affects another event (the effect). For example, 'Driving more miles leads to using more gas.'

What is the domain of a set of ordered pairs?

Back

The domain is the set of all first elements (x-values) in the ordered pairs. For example, in the set m = {(1,3), (2,4), (3,6), (2,7)}, the domain is {1, 2, 3}.

How do you determine the formula for a sequence?

Back

To determine the formula for a sequence, identify the pattern in the terms and express it mathematically. For example, if the sequence is represented by shaded squares, the formula might be a = 2n - 1.

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, but it does not imply that one causes the other. Causation means one event is the result of the occurrence of another event.

What is the range of a set of ordered pairs?

Back

The range is the set of all second elements (y-values) in the ordered pairs. For example, in the set n = {(1,5), (2,3), (3,5), (4,4), (5,6)}, the range is {3, 4, 5, 6}.

What does it mean for a relationship to be causal?

Back

A causal relationship means that changes in one variable directly result in changes in another variable.

Front

How can you identify the domain from a set of ordered pairs?

Back

To identify the domain, list all the unique first elements (x-values) from the ordered pairs.

What is a sequence in mathematics?

Back

A sequence is an ordered list of numbers that follow a specific pattern or rule.

What is the formula for the nth term of a linear sequence?

Back

The formula for the nth term of a linear sequence can often be expressed in the form a = mn + b, where m is the common difference and b is a constant.

What is an example of a causal relationship in daily life?

Back

An example of a causal relationship is 'Studying more leads to better grades.'
