Is the statement "line plots display individual data" true or false?

Answers

Answer:

The statement "line plots display individual data" is TRUE.

Step-by-step explanation:

A line plot provides an orderly display of all the values in a data set. It displays data as points above a number line to show the frequency of each value denoted by X.

explain how to use the missing pieces strategy to compare two fractions. include a diagram with your explanation.

Answers

To tell which fraction is larger, we need to understand which one is "missing" less.
For example, we have 3/4 and 7/8.
3/4 misses 1/4.
7/8 misses 1/8.
According to the rule, we choose 7/8 as a larger one because it "misses" less then 3/4. (1/8 < 1/4)
