The data to the right represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain soccer league. construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. what percentage of players had a top speed between 26 and 29.9 km/h? what percentage of players had a top speed less than 13.9 km/h? speed number of player10-13.9 414-17.9 718-21.9 1722-25.9 8026-29.9 29630-33.9 190

explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
