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

Answer:

84

Step-by-step explanation:

Combinations

nCr

n (objects) = 9

r (sample) = 3

9C3

n! / r! (n – r)!

9! / 3! (9 – 3)!=

9! / (3! * 6!)=

9*8*7*6!/ (3! * 6!)=

6! cancels out

Let f= {(-5,1).( - 4,0).(0,6)}<br> Find f(0)<br> f(0)=
sweet [91]

<u>Given</u>:

It is given that the coordinates of the function are f=\{(-5,1),(-4,0),(0,6)\}

We need to determine the value of f(0)

<u>Value of f(0):</u>

The value of f(0) is the value of the function when the input is 0.

We need to determine the value of f(0) when the input is x = 0

Thus, from the coordinates of the function f=\{(-5,1),(-4,0),(0,6)\}, it is obvious that the input value of the function is x = 0 , then the value of the function f(0) = 6.

Thus, when the input value x = 0, the output is f(0) = 6.

Therefore, the value of f(0) = 6.

gavmur [86]

9514 1404 393

Answer:

  10

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. That is, point O is the midpoint of AC. If AO = 5, then OC = 5 and AC = 5+5 = 10.
