Q. A recent national survey of hospital admissions for people between 25 and 50 years who had hospital admissions in during a two years' period showed that 30 percent had 1 admission only, 25% had two admissions, 15 percent had 3 admissions, 12% had 4 admissions, 8 percent had 5 admissions, 10 percent had 6 admissions or more admissions. The mayor of a small city claims that his city is much healthier than the national average. He even cites the percentages for two extreme categories. He says that 40% of local population in the given age group have only one hospital admissions (compare to 30% national) and the percentage of 6 or more admissions is only 5 percent compared to national 10%. His claim was in fact based on a sample of 300 randomly selected people in the specified age group who were interviewed by the local Newspaper. It was revealed that 120 people had only 1 admission, 81 had 2 admissions, 48 had 3 admissions, 18 had 4 admissions, 18 had 5 admissions, and 15 had 6 admissions or more admissions. Does the data support the mayor's claim? Show the calculations or computer results.
A thin, flexible metal plate attached at one end to the platform, can be used to measure mass. When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with a period that depends on the mass attached to the pl..

An 11.00 kg crate is placed on a horizontal conveyor belt. The materials are such that static friction = 0.47 and kinetic friction = 0.24.
A vertical scale on a spring balance reads from 0 to 160 N. The scale has a length of 12.5cm from the 0 to 160 N reading. A fish hanging from the bottom of spring oscillates vertically at the frequency of 2.30 Hz. ignoring the mass of the spring, wha..
