A histogram is titled Heights of People in Line. A horizontal axis is labeled Inches from 30 to 66. A vertical axis is labeled Frequency from 0 to 24. The histogram contains twelve vertical bars. From left to right, the first bar covers 30 to 33 on the horizontal axis and has height 2. The second bar covers 33 to 36 on the horizontal axis and has height 0. The third bar covers 36 to 39 on the horizontal axis and has height 3. The fourth bar covers 42 to 45 on the horizontal axis and has height 11. The fifth bar covers 45 to 48 on the horizontal axis and has height 23. The sixth bar covers 48 to 51 on the horizontal axis and has height 7. The seventh bar covers 51 to 54 on the horizontal axis and has height 5. The eigth bar covers 54 to 57 on the horizontal axis and has height 10. The ninth bar covers 57 to 60 on the horizontal axis and has height 21. The tenth bar covers 60 to 63 on the horizontal axis and has height 0. The eleventh bar covers 6345 to 66 on the horizontal axis and has height 17.The twelveth bar covers 6345 to 66 on the horizontal axis and has height 1.

To determine how many people could not go on the ride, we need to find the total number of people whose heights are less than 54 inches (which is equivalent to 4 feet 6 inches). We'll examine the heights represented in the histogram:

  • 30 to 33 inches: 2 people
  • 33 to 36 inches: 0 people
  • 36 to 39 inches: 3 people
  • 39 to 42 inches: 0 people
  • 42 to 45 inches: 11 people
  • 45 to 48 inches: 23 people
  • 48 to 51 inches: 7 people
  • 51 to 54 inches: 5 people

Next, we add up the frequencies of these heights:

\[ 2 + 0 + 3 + 0 + 11 + 23 + 7 + 5 = 51 \]

Thus, the total number of people who could not go on the ride is 51.

Final answer: 51.
