Answer:
a: 12.8%
Explanation:
Standard Deviation would be calculated with the probability approach since there is probability given in the question.
- Formula of Standard Deviation and the solution is given in the pictures below.
- Although ERR the required part to calculate Standard Deviation is calculated in the text.
Calculating ERR:
ERR= Sum of Probabilities × Rate of returns.
In our question = ERR= 0.2 × 30% + 0.5 × 10% + 0.3 × (-6%) = 0.128 = 12.8%
Thus, by putting all the values in the formula you will get the answer 12.8%.

Answer:
Short run aggregate supply curve is flat ( A )
Explanation:
The special case of the AS-AD following the IS-LM is that the short run aggregate supply curve is flat
This is because in an AS-AD model the price level is constant and AD represents an equilibrium point along IS-LM model, hence the price been constant, shows that in short run aggregate supply curve will be flat.
