Complete the following table: Adapted from Illustrative Mathematics N-RN Extending the Definitions of Exponents, Variation 2 Examples & Explanations The student conducting the study wants to create a table with more entries; specifically, she wants to fill in the population at each half hour. However she forgot to make these measurements so she want s to estimate the values. Complete the following table: Adapted from Illustrative Mathematics N-RN Extending the Definitions of Exponents, Variation 2 Examples & Explanations What if the student wanted to estimate the population every 20 minutes instead of every 30 minutes.
