the yearbook club has 5 members returning from last year. they set up a booth in the cafeteria to recruit more members, and an average of 3 new members sign up each day. which best describes why the graph relating the total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be continuous or discrete?\n\nthe graph will be continuous because an end day for the booth being set up is not given in the description.\n\nthe graph will be continuous because there can be any number of people signing up each day since we are only given the average.\n\nthe graph will be discrete because some day the number of available people to sign up for the club will run out.\n\nthe graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.

Answer

Brief Explanations:

To determine if the graph is continuous or discrete, we analyze the nature of the variables. The total number of members ( m ) and the number of days ( d ) are related by the context of people signing up. A discrete graph is used when the data consists of distinct, separate values (like the number of people, which must be whole numbers as you can't have a fraction of a person).

  • Option 1: The presence or absence of an end day does not determine if a graph is continuous. Continuity is about the nature of the data values, not the duration. Eliminate this.
  • Option 2: Even with an average, the number of people signing up must be a whole number (you can't have a partial person). So the data can't take any real number value, so it's not continuous. Eliminate this.
  • Option 3: The graph being discrete is not because people "run out" to sign up, but because the number of members is a count of whole people. The reasoning here is incorrect. Eliminate this.
  • Option 4: Since the number of members must be a whole number (no partial people) and the booth is set up once per day (so days are distinct), the data points for ( m ) and ( d ) will be distinct, separate values. This means the graph is discrete.

Answer:

D. The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
