Suppose a firm has the production function, Q = 12KL. It has a contract to produce 144 units of output per day. One way to do is to use 3 units of capital (K) and 4 units of labor (L). Suppose a unit of labor costs $2 (wage = w) while a unit of capital costs $3 (r).

What is the Marginal Rate of Technical Substitution (MRTS) at this specific input ratio, i.e., K = 3 and L = 4?

A) MRTS = 1/3

B) MRTS = 1/2

C) MRTS = 3/4

D) We do not have sufficient information to find out the value of MRTS at this combination.

A WNba player makes 75% of her free throws. Assume that the player takes 6 free throws during the game. The distribution for the number of made free throws in 6 attempts is.

x || 0 ||    1 || 2 || 3 || 4 || 5 || 6 ||      

P(X) || 0.0002 || 0.0044 || 0.0330 || 0.1318 || 0.2966 || 0.3560 || 0.1780 ||

1. What is the probability of making at making fewer than 3 free throws.

2. What is the probability of making at least 4 of the free throws?

3. What is the mean number of free throws you expect the player to make?

4. What is the standard deviation for the number of free throws made by this player?

Consider the reaction: C2H4(g) + H2(g) <-> C2H6(g). For this process, deltaH = -137.0 kj/mol and deltaS = -120.6 J/mol*K. Based on these data and assuming deltaH and deltaS are temperature independent, answer the following questions;

1) Does this reaction favor products or reactants at 25 degrees C?

2) At 25 degrees C, is the reaction driven(dominated) by the entropy or the enthalpy?

3) Would a decrease in temperaturefavor the reactants or the products?

4) At what temperature would the equilibrium constant (K) equal unity (=1.0)?

The answers should be 1:products, 2:enthalpy, 3:products and 4:???? but I don't know why! Explaination please and answer to #4.

Write a program in C++ coding that utilizes a DO-WHILE loop to redisplay a menu to the user.

Ask the user to input their favorite SuperHero and display a positive or funny comment about the chosen SuperHero. If RBG is chosen, display "You can't spell TRUTH without RUTH."

Utilize a Do-While Loop to redisplay the menu to the user after item 1, 2 or 3 is executed. If item 4 is chosen, end the program.

If the user chooses 4, end the program.

1. Superman (or a SuperHero of your Choice)

2. Batman (or a Superhero of your choice)

3. The Notorious RBG (non-negotiable, RBG must be a menu choice)

4. Quit
