Lots of parents wonder whether their child is bigger or smaller than other kids the same age. (In the United States, the average baby weighs about 7Â½ pounds at birth.) To give you a benchmark, here are the values from the 25th percentile to the 75th percentile for weight and height â meaning that half of kids fall within these ranges. A quarter of kids fall above these numbers and a quarter of kids below them.
The first production Model T was built on September 27, 1908, at the Piquette Plant in Detroit, Michigan. The Model T was the first automobile mass produced on assembly lines with completely interchangeable parts, marketed to the middle class. There were several cars produced or prototyped by Henry Ford from the founding of the company in 1903 until the Model T came along.
In 1896, the Duryea Motor Wagon became the first production motor vehicle in the United States. In that same year, Henry Ford demonstrated his first experimental vehicle, the Quadricycle. By 1908, when the Ford Motor Company introduced the Model T, the United States had dozens of automobile manufacturers. The Model T quickly became the standard by which other cars were measured; ten years later, half of all cars on the road were Model Ts.
