Question

the staff of a game show tracked the performance of all the contestants during the past season. game show scores stem leaf 1 4 4 6 8 2 2 4 4 9 3 9 4 0 4 5 4 5 8 9 6 0 1 4 4 7 3 9 8 0 1 9 0 how many people scored at least 40 points but fewer than 90 points? people

Explanation:

Step1: Analyze each stem

We need to consider stems from 4 to 8 (since we want scores at least 40 and fewer than 90).

• Stem 4: Leaves are 0, 4. So 2 scores.
• Stem 5: Leaves are 4, 5, 8, 9. So 4 scores.
• Stem 6: Leaves are 0, 1, 4, 4. So 4 scores.
• Stem 7: Leaves are 3, 9. So 2 scores.
• Stem 8: Leaves are 0, 1. So 2 scores.

Step2: Sum the number of scores

Now we sum the number of scores from each stem: \(2 + 4 + 4 + 2 + 2\)
First, \(2+4 = 6\), then \(6 + 4 = 10\), then \(10 + 2 = 12\), then \(12 + 2 = 14\).

Answer:

14
