13. Given the following historical data and weights of .5, .3, and .2, what is the three-period weighted moving average forecast

Ostrovityanka [42]

Answer:

b. 144.8

Step-by-step explanation:

When calculating the moving average estimate of an observation , each of the observations are usually computed with the same weighted . In some cases, it is beneficial to assign different weight on the observations such that the observation closer to the time period being forecast, has higher weight. This is refer to as weighted moving average technique. The sum of the individual weight in a weighted moving average technique must equal to 1.

The three-period weighted moving average forecast for period 5 = 144*0.5 + 148 *0.3 + 142 *0.2 = 144.8

Vonda works between 30 and 32 hours per week at a hair salon. She pays a one time $250 chair rental fee, and earns $40 per hour

Vlad1618 [11]

Answer:

The practical domain of the function is [30,32].

Step-by-step explanation:

The given function is

$p(h)=40h-250$

where, p(h) represents the Vonda's weekly pay as a function of hours worked.

She pays a one time $250 chair rental fee, and earns $40 per hour that she works.

Domain is the set of all possible inputs.

The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.

It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,

$30$

Therefore practical domain of the function is [30,32].
