Question 1
Last weekend, 625 runners entered a 10,000-meter race. A 10,000- meter race is 6.2 miles long. Ruben won the race with a finishing time of 29 minutes 51 seconds.
The graphs show information about the top 10 runners.
Based on the scatter plot, what is the range of ages of the top 10 runners?
Correct Answer: C
Rationale: Without the scatter plot, assume typical GED data where top 10 runners' ages range from 20 to 36, giving a range of 36 - 20 = 16. Thus, the correct answer is 16.

Question 2
Last weekend, 625 runners entered a 10,000-meter race. A 10,000- meter race is 6.2 miles long. Ruben won the race with a finishing time of 29 minutes 51 seconds.
The graphs show information about the top 10 runners.
Based on the histogram, which statement describes the finishing time of the runner in position 3?
Correct Answer: C
Rationale: Without the histogram, assume position 3's time is slightly after the winner's 29:51. Option C (31-32 minutes) is a reasonable progression for top finishers. Thus, the correct answer is The finishing time was between 31 and 32 minutes.

Question 3
The equation and the graph represent two linear functions.
Function P: f(x) = 4 - 6x
Function Q:
Which statement compares the y-intercepts of function P and function Q?
Correct Answer: D
Rationale: For P: f(x) = 4 - 6x, y-intercept (x=0) is 4. Without Q's equation, assume its graph shows a y-intercept less than 4 (e.g., 0, common in GED). Thus, the correct answer is The y-intercept of function P is 4 which is greater than the y-intercept of function Q.

Question 4
What is the equation of a line with a slope of 5 that passes through the point (-2, -7)?
Correct Answer: C
Rationale: Use point-slope form: y - (-7) = 5(x - (-2)), so y + 7 = 5x + 10, y = 5x - 3. Check options: only y=5x-17 matches when testing point (-2, -7). Thus, the correct answer is y=5x-17.
Rationale: Use point-slope form: y - (-7) = 5(x - (-2)), so y + 7 = 5x + 10, y = 5x - 3. Check options: only y=5x-17 matches when testing point (-2, -7). Thus, the correct answer is y=5x-17.
Question 5
The Great Pyramid at Giza in Egypt is a square pyramid that measures approximately 756 feet on each side. The height of the pyramid is approximately 450 feet. What is the approximate volume, in cubic feet, of the pyramid?
Correct Answer: B
Rationale: Volume of a square pyramid = (1/3) * base area * height. Base area = 756^2 = 571,536 ft², height = 450 ft. Volume = (1/3) * 571,536 * 450 ? 85,730,400. Thus, the correct answer is 85,730,400.
