The answer is the first one: Whether participants liked or didn't like each photo and What part of the brain was active while viewing pictures.

Explanation for each option:

  1. Whether participants liked or didn't like each photo: This is a dependent variable because it measures the participants' responses to the photos, which can vary based on the conditions of the experiment.

  2. Whether the photos were neutral, risky, or the participant's own: This is an independent variable because it categorizes the types of photos shown to participants, which are manipulated by the researchers.

  3. Whether the photos were popular or unpopular: This is also an independent variable because it categorizes the photos based on their popularity, which is another condition manipulated by the researchers.

  4. Whether participants' brains were scanned or not: This is an independent variable because it refers to a condition of the experiment (whether or not brain scanning was performed).

  5. What part of the brain was active while viewing pictures: This is a dependent variable because it measures the brain activity in response to viewing the pictures, which can vary based on the conditions of the experiment.

Summary: The two dependent variables in the study are:

  1. Whether participants liked or didn't like each photo.
  2. What part of the brain was active while viewing pictures.

The bar graph gives the life expectancy for men in a certain community born in six selected years. Complete parts a through c. Use the coordinates of the two points that show male life expectancies for 1980 and 2000 to write a linear function that models life expect E(x), for men born in this community x years after 1960. E(x)= (Use integers or decimals for any numbers in the expression. Type your answer in slope-intercept form.)
