Answer:
a) Demand for next week (2-weeks-moving-average) = 11 dozens
a) Demand for next week (3-weeks-moving-average) = 9 dozens
Step-by-step explanation:
The moving average used for forecast takes past values and average them to predict future values fo the variable.
Is calculated by taking the arithmetic mean of a given set of values. In this case, we will forecast using 2 and 3 weeks.
In the case of 2 weeks moving average, we take the last two weekly sales and average them:

For the case of 3 weeks moving average, we take the last three weekly sales and average them:

The correct answer is 6/10 because 9-3 equal 6 and the denominator stays the same
Answer:
option c
amplitude 1 ; period 2π/3
Step-by-step explanation:
Given in the question a function,
f(t)=-cos3t
Standard form of cosine function is
f(t)=acos(bt)
Amplitude is given by = |a|
Period of function is given by = 2π/b
So the amplitude is |-1| = 1
the period is 2π/3 = 2π/3
