Question

alice needs to calculate the average pressure inside a gas cylinder. she has access to both a data table showing the pressure over time and a graph of pressure over time. which representation is probably most useful to her if she wants a precise answer? graph data table

Explanation:

A data table provides exact numerical values. When calculating an average (which requires precise numerical input), having exact pressure values at specific times (from the data table) allows for accurate arithmetic operations (summing values and dividing by the number of data points). A graph, while it can show trends, typically involves estimating values (by reading points on the axes), which introduces potential error due to visual approximation.

Answer:

data table
