Every day, a random sample of 325 computer memory chips produced by a factory is tested to see if the chips meet their minimum speed ratings for certain operations. if 3 of the chips failed the test on a day when 15,500 chips were made, which is the best estimate of the number of memory chips made that day that are likely to meet the minimum speed ratings for those operations?

Power plants that rely on coal increase the amount of sulfur dioxide that dissolves into the air, eventually increasing the acidity of precipitation. the higher acidity of rain and snow can damage forests by making it more difficult for plants to absorb minerals from the soil. the equations below provide information about the market demand and supply of electricity. there is a constant marginal external cost of $25 per unit of electricity.d: qd= 200 – 2ps: qs=p – 10what quantity of electricity satisfies allocative efficiency in this market? a. 60b. 70c. 50d. 43.3
