Answer:
B) 1.7
Explanation:
GDP deflator simply shows the occurring event of the level of prices in the economy which is why It is often the ratio of nominal GDP to real GDP. 
GDP deflator in 2009 will be:
Norminal GDP
Cost of apple= $1 in 2009
Apple produced =5 in 2009
Cost of oranges= $1.50 in 2009.
Orange produce= 5 in 2009
 $1.00*(5)+$1.50*(5)
=5+7.5
=$12.50
Real GDP
Cost of apple= $0.50 in 2002
Apple produced =5 in 2002
Cost of oranges= $1 in 2002
Orange produce= 5 in 2002
0.50*(5)+$1.00*(5)
=2.5+5
=$7.50
 GDP deflator = Nominal GDP/Real GDP)
=$12.50/$7.50
=1.666
approximately 1.7

Answer:
The portfolio return is 12.6% and the portfolio SD is 15.4%. Thus, option a is the correct answer.
Explanation:
The expected return of a portfolio is the weighted average of the individual stock returns that form up the portfolio. Thus, the expected return for a two stock portfolio is,
Return of Portfolio =  wA * rA  +  wB * rB
Where,
- w represents the weight of each stock in the portfolio
- r represents the return of each stock
Portfolio return = 0.7 * 0.15  +  0.3 * 0.07  =  0.126  or 12.6%
The standard deviation of a two stock portfolio containing one risky and one risk free asset is the weight of risky asset in the portfolio multiplied by the standard deviation of the risky asset. The risk free asset has zero standard deviation.
Standard deviation of such a portfolio is,
Portfolio SD = w of risky asset * SD of risky asset
Portfolio SD = 0.7 * 0.22   
Portfolio SD = 0.154 or 15.4%
 
        
             
        
        
        
Answer:
a. decreases, so aggregate demand shifts left. 
Explanation:
When tax is increased, disposable income reduces and therefore consumption falls. The fall in consumption shifts the aggregate demand curve to the left.
