problem 3 (lesson 17)
the line plot shows the lengths some students jumped in inches.
jump length (inches)
a. what is the longest jump? what about the shortest?
b. how much longer is the longest jump than the shortest jump?
c. how many measurements are shown in the graph?

Explanation:

Part a

To find the longest and shortest jump, we look at the maximum and minimum values on the jump length line plot. The shortest jump is at 28 inches (the leftmost 'x') and the longest at 42 inches (the rightmost 'x').

Step1: Identify longest and shortest

Longest = 42, Shortest = 28

Step2: Subtract shortest from longest

$42 - 28 = 14$

Step1: Count 'x's at each length

• 28: 1
• 30: 2
• 31: 2
• 32: 3
• 33: 2
• 35: 2
• 36: 1
• 38: 1
• 42: 1

Step2: Sum the counts

$1 + 2 + 2 + 3 + 2 + 2 + 1 + 1 + 1 = 15$

Answer:

Longest jump: 42 inches, Shortest jump: 28 inches
