- What is the total effect on the economy of a government tax rebate of $1,000 to each household in order to stimulate the economy if each household will spend 90% of the rebate in goods and services?An editorial in The New York Times on Sunday, June 4, 2011 discussed the redesigned fuel economy stickers to be required on new cars starting in 2013. Consider a new midsize Ford Fusion S model. At $4-a-gallon gas, annual fuel costs would be about $2,200 for 15,000 miles driven. ... And that’s for a car with a rated mileage of 34.9 m.p.g. (actual highway mileage, as with all vehicles, is lower, in this case about 27 m.p.g.). Industry clearly needs to do better. Did the Times use the rated or the actual mileage in its computation? In Canada, some multi-lane highways have a speed limit of 110 km/hour. Convert this speed to miles per hour, so you'll know how fast you may drive in Canada.In a community with a population of 5,000 people where 60% were male, 200 vehicular accidents were reported in the year 2012 wherein 60 cases were attributed to female drivers. calculate the sex ratio (Male:Female) of the population.
