Question

Ms. Rumble's history class conducted interviews with their grandparents for a class project. The grandparents less than 89 years old knew that Amelia Earhart was the first woman to fly solo across the Atlantic Ocean. Determine the graph to represent this scenario. number line with open circle on the number 89 and line shaded to the right number line with closed circle on the number 89 and line shaded to the right number line with closed circle on the number 89 and line shaded to the left number line with open circle on the number 89 and line shaded to the left

Answer 1

D) Number line with an open circle on the number 89 and a line shaded to the left.

Explanation:

The scenario described indicates that the grandparents who knew about Amelia Earhart are those who are less than 89 years old. In set notation, this would be represented as:

`\large\boxed{\sf Grandparents' \;ages < 89}`

To represent this on a number line, we should use an open circle on the number 89 (indicating that 89 itself is not included) and shade the line to the left (indicating ages less than 89).

So, the correct choice is:

• D) Number line with an open circle on the number 89 and a line shaded to the left.
