Substitute x = y + 1 into 2x - 3y = -1

2 - y = -1

Solve for y in 2 - y = -1

y = 3

Substitute y = 3 into x = y + 1

x = 4

Given an actual demand of 59, a previous forecast of 64, and an alpha of .3, what would the forecast for the next period be usin

marshall27 [118]

Answer:

62.5

Step-by-step explanation:

Data provided in the question:

Actual demand = 59

Previous forecast = 64

Alpha = 0.3

Now,

The forecast for the next period be using simple exponential smoothing will be given as

= [ Alpha × Actual demand ] + [ (1 - Alpha) × Previous forecast ]

= 0.3 × 59 + [ ( 1 - 0.3 ) × 64 ]

= 17.7 + 44.8

= 62.5

Look at the table to answer the question.

Answer:

Your power function is y=-2 $x^{2}$

Step-by-step explanation:

The way I found it was.

0=0, so, the function multiply by zero, and have no other term to add

A number (one in a case) gives as a result: -2. So, one, elevated to ANY power results in one, every time. So, I have 1, as a factor and -2 as a result. One is as well a factor that delivers a result equal to the other factor. (3)(1)=3 , (8987)(1)=8987. So, the other factor must be -2

Then I checked all the table, and the results were consistent.
