Write an addition expression represented by the number line. Then find the sum. A number line from negative 4 to 4. It has two arrows on top of it. One arrow begins at 0 and ends at negative 3. It is labeled negative 3. Another arrow begins at negative 3 and ends at 1. It is labeled 4.

An addition expression is ?
.

The sum is ?

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

Find the cosine function that is represented in the graph.
