In Exercises 91 and 92, you are giventhe dollar value of a product in 2016 and the rate at whichthe value of the product is expected to change duringthe next 5 years. Use this information to write a linearequation that gives the dollar value V of the product interms of the year t. (Let t = 16 represent 2016.)2016 Value Rate91. $3000 $150 decrease per year92. $200 $6.50 increase per year
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
In Exercises 91 and 92, you are given
the dollar value of a product in 2016 and the rate at which
the value of the product is expected to change during
the next 5 years. Use this information to write a linear
equation that gives the dollar value V of the product in
terms of the year t. (Let t = 16 represent 2016.)
2016 Value Rate
