- 1: Quantitative Reasoning 1. An article from October 3, 2007 in The Washington Post about how paper and plastic bags impact the environment, states that: "Worldwide, an estimated 4 billion plastic bags end up as litter each year. Tied end to end, the bags could circle the Earth 63 times." A) assume a plastic bag is 18 inches long. Verify the claim in the article B) use scientific notation and estimation to convince yourself that “4 billion plastic bags” is too small by several powers of ten. ( estimate how many plastic bags the world uses each year)Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 44% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below. a. Find the probability that both generators fail during a power outage. (Round to four decimal places as needed.) b. Find the probability of having a working generator in the event of a power outage. Is that probability high enough for the hospital? Assume the hospital needs both generators to fail less than 1% of the time when needed.(Round to four decimal places as needed.)IF YOU WANT A HELPFUL RATING DO IT WITHIN 15 MINUTES ..
