Enter your answer to one decimal place.week 1: 167week 2: 133week 3: 180week 4: 171week 5: 177week 6: 208Correct Answer: -8.3QUESTION 3: CALCULATED FORMULABrooks & Company are preforming time series analysis on their sales data for their mostpopular product. The average sales seasonal variation (000 units) for each quarter iscalculated as: Qtr I is 4, Qtr Il is -1, Qtr Ill is -1 and Qtr IV is 7.Calculate the adjusted average seasonal variation (000 units) for Qtr l. (Hint: you mustcalculate the adjustment first). Answer correct to one decimal place.Correct Answer: O1.8QUESTION 4:Page & Company has had the quarterly sales (000 units) given below for the last two years.Calculate a trend figure (in 000 units) for quarter IIl of year 1 using the appropriate movingCALCULATED FORMULAaverages. Enter your answer to nearest whole number.Sales data (000 units) year 1: Qtr I is 118, Qtr Il is 164, Qtr IIl is 68 and Qtr IV is 53Sales data (000 units) year 2: Qtr I is 200, Qtr Il is 232, Qtr IIl is 118 and Qtr IV is 86Correct Answer: 111QUESTION 5: CALCULATED FORMULAThe quarterly sales (in 000s units) for the past three years of a dune buggy have been analThe trends, average seasonal variations and adjusted average seasonal variations have becalculated. Some of the adjusted average seasonal variations (in 000s units) are:Quarter 1: 18.5 Quarter 2:-5.6 Quarter 3: -8.4The regression equation for the sales trend is given as Y = 85 +4.5X, where Y is the trendunits) and X represents the time periods, starting with X = 1 for Quarter I of the first of thyears.Use the adjusted average seasonal variation figures and the regression equation to forec:(to the nearest unit) for Quarter 1 of the fourth year.Correct Answer: 162,000

Document (5) Saved Parents often wonder, usually out of sheer curiosity, how tall their child will be as an adult. When a child has a medical condition or appears to be growing abnormally, the need to under-stand his or her growth can be important. One early method involved simply doubling a child's height at age 2. This gave very inaccurate results, especially for girls. As a result, many better methods have been developed to try to accurately predict a child's eventual adult height from various factors. 1. One simple method to predict adult height is to average the parents' heights and then add 2.5 inches if the child is a boy or subtract 2.5 inches it the child is a girl. This method can be fairly accurate, but can also be as much as 5 inches above or below the child's eventual height. Write a formula or formulas to express this calculation, and clearly define any variables that you use. 2. Another method is to add the parents' heights and then add an additional 5 inches if the…
8. Exponential candy A student opened a bag of M&M'S® Chocolate Candies, dumped them out, and ate all the ones with the "M" on top. When he finished, he put the remaining 30 M&M'S back in the bag and repeated the same process over and over until all the M&M'S were gone. Here are data on the number of M&M'S remaining at the end of each of the first 6 courses.
