Question by question
A question scores 100 minus the bracket’s width as a percentage of the track, if the answer is inside it, and nothing if it is outside. The tenth-of-the-track bracket below is the one a confident player was aiming for.
- How many people does Michigan Stadium seat? 107,600 — in the upper third of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 91,000 to 130,000 is a tenth of the track and scores 90; the whole track scores 0.
- How tall is the average American woman? 64 inches — near the middle of its track. A bracket from 62 to 66 is a tenth of the track and scores 90; the whole track scores 0.
- What is 87 × 46? 4,002 — in the upper third of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 3,100 to 5,200 is a tenth of the track and scores 90; the whole track scores 0.
- What is the hottest air temperature ever recorded on Earth? 134 degrees Fahrenheit — near the middle of its track. A bracket from 129 to 139 is a tenth of the track and scores 90; the whole track scores 0.
- How many transistors were in the Intel 4004, the first microprocessor? 2,300 — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 1,500 to 3,600 is a tenth of the track and scores 90; the whole track scores 0.
