The following data are sales data from a coffee shop. be careful looking at these data because one column is sales data and one column is a running exponential smoothing forecast. create a sales forecast for week 10 using the following forecasts: a moving average with k = 4, a weighted moving average with k = 3 and the weights of t = .50, t-1 = .30, and t-2 = .20, and an exponential smoothing model using an alpha of .20.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

ratio is 2 : 9

the answer is three

13.5 : 3

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: 12   they all have at least 28 days
