Final answer:
The percentage decline of the NASDAQ stock market from its peak of 5,170 in 2000 to 1,315 two and a half years later is approximately 74.56%.
Step-by-step explanation:
The question asks for the percentage decline of the NASDAQ stock market from its peak at 5,170 in 2000 to its value at 1,315 two and a half years later. To find the percentage decrease, we use the formula:
Percentage Decrease = ((Original Value - New Value) / Original Value) × 100%
Substituting the given values, we get:
Percentage Decrease = ((5,170 - 1,315) / 5,170) × 100% = (3,855 / 5,170) × 100%
Calculating the division, we get:
Percentage Decrease = 0.74564 × 100%
Rounded to two decimal places, the percentage decrease is:
Percentage Decrease = 74.56%
Therefore, the NASDAQ stock market experienced a decline of approximately 74.56% from its peak in 2000 to two and a half years later.
