Question 6
The line plot shows the lengths of the pencils in a pencil cup, measured to the nearest quarter inch. Each X is one pencil.
How many pencils were measured?
Correct answer: A
Count every X: 2 + 3 + 5 + 1 + 2 + 0 + 1 = 14 pencils. The answer 7 counts the lengths on the number line, not the X marks.
-
Question 7
The line plot shows the lengths of the pencils in a pencil cup, measured to the nearest quarter inch. Each X is one pencil.
Which length was measured most often?
Correct answer: B
4½ inches has the tallest stack, with 5 X marks. 4¼ inches has only 3.
-
Question 8
The line plot shows the lengths of the pencils in a pencil cup, measured to the nearest quarter inch. Each X is one pencil.
How many pencils are longer than 4½ inches?
Correct answer: B
Longer than 4½ means 4¾, 5, 5¼ and 5½: 1 + 2 + 0 + 1 = 4 pencils. The answer 9 also counts the 5 pencils that are exactly 4½ inches.
-
Question 9
The line plot shows the lengths of the pencils in a pencil cup, measured to the nearest quarter inch. Each X is one pencil.
How many pencils are exactly 4¼ inches long?
Correct answer: C
There are 3 X marks above 4¼. Be careful not to read the stack above 4 (2 X marks) or 4½ (5 X marks).
-
Question 10
The line plot shows the lengths of the pencils in a pencil cup, measured to the nearest quarter inch. Each X is one pencil.
How many more pencils are 4½ inches long than 4 inches long?
Correct answer: C
There are 5 pencils at 4½ inches and 2 pencils at 4 inches, so 5 − 2 = 3 more. 7 adds the two stacks instead of finding the difference.
Questions you leave blank are not counted as wrong.
