Answer:
The three period moving average forecast for week 6 is 24.
Step-by-step explanation:
the moving average forecast for period 6 is given by the sum of last three week data and divide it by three.

thus the forecast for 6 week = 72/3 = 24
It's simple!
Because that a composite figure is made of other / combining rectangular prisms, you can find the composite figure's volume by finding the volumes of those combined rectangular prisms and adding them up.
