Biology Consider the following given statements and conclusion.
Given: If an animal is a fish, then it has gills.
A turtle does not have gills.
You conclude: A turtle is not a fish.
- Make a Venn diagram to illustrate the given information.
- Use the Venn diagram to help explain why the argument uses good reasoning.
-
Reasoning Use the following algorithm: Choose an integer. Multiply the integer by 3. Add 6 to the product. Divide the sum by 3.
- Complete the algorithm for four different integers. Look for a pattern in the chosen integers and in the corresponding answers. Make a conjecture that relates the chosen integers to the answers.
- Let the variable x represent the chosen integer. Apply the algorithm to x. Simplify the resulting expression.
- How does your answer to part (b) confirm your conjecture in part (a)? Describe how inductive and deductive reasoning are exhibited in parts (a) and (b).
