Question

  1. astronomy astronomers reported the speed of the compact star us 708 as the fastest ever observed at 2.7 million miles per hour. select the option that best describes the accuracy of the report. a the report is very accurate because scientists can measure speed quite accurately. b the report is probably accurate because the number is not very specific. c the report is not accurate because there is no way to measure the speed of a star. d the report is not accurate because the speed of a star is not constant. 25. true or false: the sum of π and 3.14 is a rational number. a true b false

Explanation:

Brief Explanations
  1. Scientists can measure speeds quite accurately, so the report is very accurate.
  2. $\pi$ is an irrational number and 3.14 is a rational - approximation of $\pi$. The sum of an irrational number ($\pi$) and a rational number (3.14) is an irrational number, not a rational number.

Answer:

  1. A. The report is very accurate because scientists can measure speed quite accurately.
  2. B. False
