From a distance of 300 feet, a car approaches you at a speed of 48 feet per second. The distance d (in feet) of the car from you after t seconds can be described by the equation d=|300−48t|. At what moments does the car find itself 60 feet away from you?
Answer:
The exact population of Vermont in 2008 could have been around 618,000
Step-by-step explanation:
* Here's how rounding to the nearest ten thousand works:
- Numbers ending with the last four digits between 0001 and 4999 are rounded down to the nearest lower multiple of ten thousand
- Example: 83,525 rounds down to 80,000.
- If the last four digits are 5000 or above, round up to the next higher ten thousand
- Example: 58,988 rounds up to 60,000
* Applying this rule to the problem given:
Since the rounded population is 620,000 to the nearest ten thousand, the actual population could be any value with the last four digits from 0001 to 4999 (like 618,000) or from 5000 upwards (like 624,000).
Therefore, 618,000 might represent the actual population of Vermont in 2008
In the seventh-grade data, the left side appears similar to the right side, unlike in the fifth-grade data. In seventh grade, we can divide the dots into two equal segments, one ranging from 0 to 3 and the other from 4 to 7. The distribution in the first segment is {2, 2, 3, 5}, while the second segment has {5, 3, 3, 1}. These sides mirror each other. When attempting a comparable division in the fifth-grade data, we find one segment from 1 to 4 with a distribution of {2, 3, 1, 4}, and another from 5 to 8 with a distribution of {5, 5, 2, 2}. In this case, the left side does not reflect the right side, indicating a lack of symmetry.
