Full solution

Q. Anne is planning her wedding. The number of guests she wants to invite determines the number of announcements she orders.

\newline

g =

the number of guests

\newline

a =

the number of announcements

\newline

Which of the variables is independent and which is dependent?

\newline

Choices:

\newline

(A)

a

is the independent variable and

g

is the dependent variable

\newline

(B)

g

is the independent variable and

a

is the dependent variable

Definition of Variables: In this context, the independent variable is the one that is chosen freely or controlled by the person conducting the experiment or planning the event. The dependent variable is the one that depends on the independent variable.
Independent Variable: Number of Guests: Anne is planning her wedding and the number of guests she wants to invite $g$ is chosen by her. This number is not influenced by any other factor in this scenario. Therefore, $g$ is the independent variable.
Dependent Variable: Number of Announcements: The number of announcements $a$ that Anne orders will depend on the number of guests she is inviting. If she invites more guests, she will need more announcements, and if she invites fewer guests, she will need fewer announcements. Therefore, $a$ is the dependent variable.
