If a coin is tossed 100 times, we would expect approximately 50 of the outcomes to be heads. It can be demonstrated that a coin is unfair if \(h,\) the number of outcomes that result in heads, satisfies \(\left|\frac{h-50}{5}\right| \geq 1.645 .\) Describe the number of outcomes that determine an unfair coin that is tossed 100 times.
In \(2012,\) the United States government spent more than it had collected in taxes, resulting in a budget deficit of 1.09 trillion dollar a. Express 1.09 trillion in scientific notation. b. There are approximately 32,000,000 seconds in a year. Write this number in scienfic notation. c. Use your answers from parts (a) and (b) to determine approximately how many years is 1.09 trillion seconds. (Note: 1.09 trillion seconds would take us back in time to a period when Neanderthals were using stones to make tools.)
