The correlation coefficient is a statistical measure that figures the quality of the connection between the relative developments of the two factors. The scope of qualities for the relationship coefficient limited by 1.0 on a flat out esteem premise or between - 1.0 to 1.0. In the event that the relationship coefficient is more prominent than 1.0 or not exactly - 1.0, the connection estimation is inaccurate. A connection of - 1.0 demonstrates an immaculate negative correlation, while a connection of 1.0 demonstrates a flawless positive correlation. A connection of 0.0 shows zero or no connection between the development of the two factors.
Answer:
(i) Q=300
(ii) Elasticity of Demand=-3.33 (elastic)
(iii) Income Elasticity= 2.5 (normal good)
(iv) Advertising Elasticity: 1.5
Explanation:
The Demand function is given by
(1) To solve (i) we need to replace P = 200, I = 150, and A = 30 in the demand equation:
(2) To find the price elasticity (how much quantity demanded changes with price) we use the point price elasticity formula
From the above equation we get: 
Replacing in the elasticity formula
in absolute terms the elasticity is bigger than one so it is an elastic demand.
(3) For income elasticity (how much quantity demanded changes with income), we proceed similarly as above. But the derivative is respect to income
[/tex]
Which is bigger than one, denoting this is a normal good because it's bigger than one.
(4) Advertising elasticity (how much quantity demanded changes with expenditures in advertising), we proceed as before
Answer: $25 billion
Explanation:
The increase in cash as a result of a deposit into the banking system, no cash leakages and a required-reserve ratio is:
= Deposit into banking system * Money multiplier
Money multiplier = 1 / Required reserve ratio
= 1 / 20%
= 5
Checkable deposit increase:
= 5 billion * 5
= $25 billion
Answer: an increase in the quantity of Brazilian currency that can be purchased with a dollar.
Explanation: An increase in the price of the Brazilian currency in relation to the dollar will increase the real exchange rate. This is because the exchange rate tells the amount of Brazilian baskets a US basket can buy.
The best option to relate the exchange rate with is an increase in the purchasing power of the dollar.
