Question

Marissa is ordering Negative one-sixth, negative one-third, 1.4, 0.2, two-thirds from least to greatest. Here are her steps: (1) Write each decimal as a fraction. (2) Write every fraction with a common denominator of 18. (3) Plot the numbers on the number line. (4) List the numbers from left to right as they are plotted on the number line. Identify any and all errors that Marissa made in her steps. Marissa should have only plotted the fractions on the number line. Marissa should have used 30 as the common denominator. Marissa should have listed the numbers from right to left after she plotted them on the number line. Marissa should have used a common denominator of 30 and should have listed the numbers from right to left after she plotted them on the number line.

Answer 1

Answer:

A graph plots Score, from 0 to 90, in increments of 10, versus Study time, in hours, from 0 to 4.5, in increments of 0.5, on an x y plane. Dozens of points rise diagonally in a tight, narrow cluster between (1.8, 62) and (4.4, 95). A regression line rises diagonally through the center of the cluster from (0, 38) to (4.2, 100). All values estimated.
