Suppose a four-period weighted average is being used to forecast demand. weights for the periods are as follows: wt-4 = 0.1, wt-3 = 0.2, wt-2 = 0.3 and wt-1 = 0.4. demand observed in the previous four periods was as follows: at-4 = 380, at-3 = 410, at-2 = 390, at-1 = 400. what will be the demand forecast for period t?

The forecast will be 397

Step-by-step explanation:

We have given:

Weights for the periods are.

wt-4 = 0.1,

wt-3 = 0.2,

wt-2 = 0.3

and wt-1 = 0.4

Demand observed in the previous four periods was as follows:

At-4 = 380,

At-3 = 410,

At-2 = 390,

At-1 = 400

The demand forecast will be:

= 0.1*380+0.2*410+0.3*390+0.4*400

= 38+82+117+160

= 397

Thus the forecast will be 397

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
