Consider the following time series data. week 1 2 3 4 5 6value 19 13 15 11 17 14using the naïve method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy. mean absolute error. round your answer to one decimal place.

answer: it is 8

step-by-step explanation:

you know why its 8

#12 the answer is the third option

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
