Answer:

3

Explanation:

Data provided in the question:

Sales for the last four months :

8, 10, 15, and 9 units

Last four forecast of sales:

9, 11, 8 and 12 units

Now,

The mean absolute deviation (MAD) value of these forecast will be calculated as:

MAD = [ ∑|Sales - Forecast sales| ] ÷ [ Total number of forecast ]

or

MAD =  [ |8 - 9| + |10 - 11| + |15 - 8| + |9 - 12| ] ÷ 4

or

MAD = [ 1 + 1 + 7 + 3 ] ÷ 4

or

MAD = 12 ÷ 4

or

MAD = 3

Qd = 600 – 4p – 0.03M – 12 Pr + 5T + 6Pe + 1.5N Where Qd = quantity demanded for commodity A; P = price of commodity A; M = cons
NISA [10]

Answer:

A. It implies a fixed 600 units of commodity A will always be demanded without being influenced by any factor that determine the quantity demanded for good ‘A'.

B. 4. Yes.  The reason is that the price of good A is indirectly proportional to the quantity demanded for good ‘A'.

C. It implies that the quantity demanded for good ‘A' decreases by 0.03 as the consumer's income increases by $1. It is an inferior good.

d. Goods A and B are complements since the negative sign implies that the quantity demanded for good ‘A' decreases as the  price of related commodity (good ‘B') (Pr) increases. The interpretation of the the slope parameter for the price of good B is that the quantity demanded for good ‘A' decreases by 12 units as the price of related commodity (good ‘B') (Pr) increases by $1.

E. Yes, the algebraic signs on the slope parameters for T, Pe, and N are correct. The reason is that quantity demanded for good ‘A' will increase as each of T, Pe, and N increases.

f. Quantity demanded for good ‘A' is 2,374.

Explanation:

A. Interpret the intercept parameter in the generalized demand function.

In the generalized demand function, 600 represents the Interpret the intercept parameter.

This implies that 600 units is a fixed units of commodity A is demanded and this is not affected by any factors that determines the quantity demanded for good ‘A'.

Therefore, it implies 600 units of commodity A will always be demanded.

B. What is the value of the slope parameter for the price of good A? Does it have the correct algebraic sign? Why? 4. Yes since indirectly proportional.

From the generalized demand function, the value of the slope parameter for the price of good A is 4.

Yes, it has a the correct algebraic sign which is a minus sign.

The reason is that the price of good 'A' is indirectly proportional to the quantity demanded for good ‘A'.

C. Interpret the slope parameter for income for income. Is good ‘A' normal or inferior? Explain. 0.03. Since Em less than 1 it is normal goods

The slope parameter for income (M) is -0.03. This implies that the quantity demanded for good ‘A' decreases by 0.03 as the consumer's income increases by $1.

It is an inferior good because the quantity demanded for good ‘A' decreases as the consumer's income increases.

d. Are goods A and B substitutes or complements? Why? Interpret the slope parameter for the price of good B.

Since the slope parameter for price of related commodity (good ‘B') (Pr) is negative (i.e. –12), this implies that goods A and B are complements.

The negative sign implies that the quantity demanded for good ‘A' decreases as the  price of related commodity (good ‘B') (Pr) increases.

The interpretation of the the slope parameter for the price of good B is that the quantity demanded for good ‘A' decreases by 12 units as the price of related commodity (good ‘B') (Pr) increases by $1.

E. Are the algebraic signs on the slope parameters for T, Pe, and N correct? Explain

Yes, the algebraic signs on the slope parameters for T, Pe, and N are correct.

The reason is that quantity demanded for good ‘A' will increase as each of T, Pe, and N increases. This implies that there is a positive relationship between the quantity demanded for good ‘A' and each of T, Pe, and N.

f. Calculated the quantity demanded for good ‘A' when P = $15, M = $25000, Pr = $40, T = 6.5, Pe = $5.25 and N = 2000?

Given;

Qd = 600 – 4p – 0.03M – 12 Pr + 5T + 6Pe + 1.5N ............... (1)

Each of the value is then substituted into equation (1) and we then calculate as follows:

Qd = 600 - (4 * 15) - (0.03 * 25000) - (12 * 40) + (5 * 6.5) + (6 * 5.25) + (1.5 * 2000)

Qd = 2,374

Worldwide annual sales of a product in 2013–2017 were projected to be approximately q = −10p + 4,700 million units at a selling
OlgaM077 [116]

The revenue function is given by R = -10p² + 4700p

Revenue is the total amount of money made from selling a particular unit of products while cost is the amount of money spent in production.

Given an annual sales (q) as:

q = (−10p + 4,700) million units.

The selling price is $p per unit. Hence:

Revenue = per unit price * annual sales

Revenue = p * (−10p + 4,700)

Revenue (R) = -10p² + 4700p

The revenue function is given by R = -10p² + 4700p

How would the market for smartphones be affected if the government charged an excise tax of $5.00 on each smartphone sold? quest
11111nata11111 [884]
<span>how would the market for smartphones be affected if the government charged an excise tax of $5.00 on each smartphone sold ? C) The supply of smartphones would decrease. Excise taxes are based on the quantity of an item and not on its value. For example, the federal government imposes an excise tax of 18.4 cents on every gallon of gas purchased, regardless of the price charged by the seller. States often add an additional excise tax on each gallon of fuel. so, government will charged 5.00$ excise tax on smartphone will affected supply of smartphones would decrease.</span>

Explanation:

Southern and Eastern Europe became the major spring regions. Some of the big driving forces is the World War I, primarily in Europe, which enabled immigrants to join the United States. The economic conditions were another significant consideration as the prospects for jobs in the war declined.

As reported, when migrants went to the USA, there were many possibilities for jobs. The American automotive industry celebrated of the first World War. War-time goods have been pursued, and America has become one of Britain's major food producers, and has provided refugees a wide range of jobs.
