An economy on the balanced growth path experiences a natural
disaster. A hurricane destroys
50% of the economy’s population and 75% of its capital stock. Show
the path of the following
variables (Note: your answer should consist of a graph of a
variable or the log of a variable on
the vertical axis, and time on the horizontal axis) and explain the
changes over time to the following variables.

B) Employment N
C) Capital stock K
D) Output Y

A survey found that? women's heights are normally distributed
with mean 63.9 in and standard deviation 2.4 in. A branch of the
military requires? women's heights to be between 58 in and 80
in.
a. Find the percentage of women meeting the height requirement. Are
many women being denied the opportunity to join this branch of the
military because they are too short or too? tall?
b. If this branch of the military changes the height requirements
so that all women are eligible except the shortest? 1% and the
tallest? 2%, what are the new height? requirements?

When the analysis is warranted, more credit will be given for answers that use the diagrams presented in class. More credit will also be given for answers that include a “story” providing an intuitive explanation of the situation. For stats-book questions, more credit will be given for more specific answers.
The prices of products and the wages paid to labor each change over time. Describe how prices and wages have changed over time. For your description of wage changes, include a description of how nominal and real wages change

How would we make a schematic design for a vending machine that accept nickels, dimes, and quarters, and sells drinks at 30 cents each? (disregard changes and there is only 1 type of drink) 2 Hexdecimal values must show the current money input (binary to hexadecimal converter is given), and when the value hits 30 or more, reset the current amount to zero, and LED should be lit to represent a successful. For the flip flop, D-flip flop should be used for simplicity.

Over the past several years, there have been increases in the number of farmers markets throughout the U.S. Additionally, during this period, the number of farmers markets accepting SNAP EBT (electronic benefits transfer of food stamps) increased as well. Explain in words the effect such simultaneous changes might have had on the market price and quantity of vegetables in the U.S. And explain the specific economic mechanisms involved. (Only use information given in this question; do not consider implications of the current pandemic.)

Consider the standard Keynesian ISLM model of the economy.
a. How does a change in animal spirits which
inspires fear of investment effect ISLM?
b. How does this effect the aggregate demand and
supply?
c. What will happen to the level of output and
price level in the short run and in the long run?
d. Illustrate the above process by deriving the
IS and LM before and after the shock, showing the change in
aggregate demand and/or aggregate supply, and by showing the short
run and long run changes of P and Y

An at-the-money call option with expiry 100 trading days later (for calculations consider that there are 250 trading days per year) is written on a stock XYZ. The volatility of the stock is 26% and the stock pays no dividends during the life of the option. The risk free rate is 5%. Can you find the delta of the option? Suppose that you own 5,000 shares of the stock XYZ, how can you use the available call options to make sure that your portfolio is not affected by changes in the stock in the short run?

(a) How many mL of a 0.1 N solution of NaOH must be added to a 25 mL solution of 0.1 N Acetic Acid to obtain a pH of 9.75? What is the concentration of Acetic Acid at this pH?
(b) Answer the same question with the following changes: [Acetic Acid] = 0.01 N in25mL and the normality of the titrant is 0.02 N. The final pH is 11.
(c) What are the alkalinity and acidity of a water that contains 79 mg/L of HCO3- and has a pH of 7.3? Assume a temperature of 25oC.
