Suppose that Bob's company uses exponential smoothing to make forecasts. Further suppose that last period's demand forecast was for 20,000 units (Ft) and last period's actual demand was 21,000 units (At). Bob's company uses a smoothing constant (alpha) of 0.4. What should be the forecast for this period

20,400 units

Explanation:

Calculation to determine What should be the forecast for this period

Using this formula

F t+1=α*D t+(1-α)

Where,

F t+1=Forecast for this period

α=Smoothing constant (alpha)

D t=Last period's actual demand

(1-α)=(1-Last period's demand forecast)

Let plug in the formula

F t+1=(0.4*21,000 units)+(1-0.4*20,000 units)

F t+1=(0.4*21,000 units)+ (0.60*20,000 units)

F t+1=8,400 units+12,000 units

F t+1=20,400 units

Therefore What should be the forecast for this period is 20,400 units

answer; /// (b) i believe its that is paid to state and federal taxing authorities;

being born in poverty would limit the people's chances, opportunities and benefits.

this happen because of several things, such as:

- poor people tend to gain less access to good education and nutrition. this mean that their chance to obtain high paying jobs would also be limited.

- poor people tend to socialize with other poor people while the rich tend to socialize with other rich people. this means that simply throguh their social circle, rich people would have more business opportunities compared to the poor people.

- rich people tend to have more capital in their disposal. this would benefit them in business since it is far easier for them to fund their business operation compared to poor people.
