You are using exponential smoothing on an annual time series concerning total revenues (in millions of dollars). You decide to use a smoothing coefficient of W=0.3, and the exponentially smoothed value for 2010 isE2010 (0.3) (12.4) + (0.7)(9.6).a. What is the smoothed value of this series in 2010?b. What is the smoothed value of this series in 2011 if the value of the series in that year is $11.2 million?a. E2010$million(Type an integer or a decimal. Do not round.)b. E2011 = $ million(Type an integer or a decimal. Do not round.)

For a given smoothing constant value of , the smoothed value for the period is given as .Here, is…

A savings account with an interest rate r, which is compounded n times per year, and begins with P as the principal (initial amount), has the discrete nt compounding formula A (t) = P(1+)". This is n because we multiply the amount by itself plus a small amount, determined by the interest rate, and the account grows each time the compounding occurs. For continuous compounding, we use the formula A (t) = Pert , and if we have seen this formula before, we may not have gotten a satisfactory answer as to why we use it, other than some vague notion of "compounding infinity times per year". In this exercise, we'll use Bernoulli's Rule to find the connection. It might be helpful to review the "Indeterminate Powers" section of the video before beginning.
