Question
The type of demand forecasting, which is based on data
from customer surveys is known as _________.Solution
1. Trend projection Here data of past sales is used to project future sales. This is the simplest and most straightforward method of demand forecasting. 2. Market research This is based on data from customer surveys. Time and effort is required to prepare and send out surveys and tabulate data. 3. Sales force composite This method uses the experience of the sales team in a company. Feedback from the sales group is used to forecast customer demand. 4. Delphi method Demand forecasting experts from outside the firm are involved in this method. Several rounds of questionnaires are held which are to be responded anonymously until the group of forecasting experts comes to a consensus. 5. Econometric A mathematical formula is created to predict future customer demand. Here, statistical tools and economic theories are combined to estimate the economic variables and to forecast the intended variables.
cos (sec-1 x) is equal to –
- sin1440° - cot630° - sin120°cos150° is equal to:
sin2 4˚ + sin2 6˚ + sin2 8˚ + sin2 10˚ + ……… + sin2 86˚ =?
Find the value of the given trigonometric expression:
(sin 40°cos 50° + cos²40°) × sin 30° + (cos 60°tan 45°) × sec 60°
...If sec 4A = cosec (3A - 50°), where 4A and 3A are acute angles, find the value of A + 75.
If cosec2A = (sin60o + tan45o X sec245o), then find the value of sin2A.
If cos2B = sin(1.5B + 27 o), then find the measure of 'B'.
Simplify the following trigonometric expression:
10 cos19∘ sec19∘ − 4cot28∘ tan28...
