Answer #1

1. Implement the given logic function using a 4:1 MUX. F(A,B,C)
= Σm(0,1,3,7)
Show the truth table, the 4:1 MUX schematic with the inputs,
select inputs and the output.
2. For an 8:3 priority encoder:
a) Draw the schematic.
b) Write the truth table.
c) Write the Boolean expressions for each of the outputs in
terms of the inputs.
d) Draw the logic circuit for the outputs in terms of the
inputs.

(a) Implement the following Boolean function F using the
two-level forms: AND-NOR and
OR-NAND , F = B'D'+ AC'D'+ACD+A'CD'
(b) Convert the above problem into standard POS, expression using
the truth table and minimize
using K-map.
(c) Design a combinational circuit with four inputs and one output.
The Algebraic expression
must be minimized using K-MAP. The output must be one for the
digits which are present in
your Roll Number Digits. Any duplications must be avoided.

1) Implement the given logic function using a 4:1 MUX. (Ref: Lec
16, slide 5)
F(A,B,C) = Σm(0,1,3,7)
Show the truth table, the 4:1 MUX schematic with the inputs,
select inputs and the output.
2) For an 8:3 priority encoder:
a) Draw the schematic.
b) Write the truth table.
c) Write the Boolean expressions for each of the outputs in
terms of the inputs.
d) Draw the logic circuit for the outputs in terms of the
inputs.

#9) You are to implement the following function
F(A,B,C,D,E,F) which outputs a 1 whenever the binary number
represented by ABCDE is ODD and 0 otherwise. A is the MSB and E is
the LSB.
Draw the function F(A,B,C,D,E,F) and show the work that led you
to that answer.
Since I am not so sadistic as to have you draw
the truth table of a 6 variable function and draw the K-map of such
a function, you should realize, as a...

1. Translate the following English expressions into logical
statements. You must explicitly state what the atomic propositions
are (e.g., "Let p be proposition ...") and then show their logical
relation.
a. If it is red then it is not blue and it is not green.
b. It is white but it is also red and green and blue.
c. It is black if and only if it is not red, green, or blue.
2. Determine if the following expressions are...

1. Suppose a firm can manufacture a product using the following
production function:
Q = f (K,L) = K^0.60 L^ 0.40)
(a) What is the APL when the firm uses 10 units of fixed capital
and 30units of labor?
(b) How does the APL change when the firm uses 100 units of
labor?
(c) Write out an expression for the MPL when capital is
fixed
(d) Show that the MPL depends on the amount of labor that is
employed by...

(Hajikhameneh & Rietz) Answer the following questions for a
consumer with utility function U(x, y) = x2 y2 and a budget
constraint of g(x, y) = 2x + 4y = 40. You must show all of your
work for full credit. a. What is the marginal utility of x? of y?
b. In one to two sentences, define the economic meaning of the term
“marginal utility.” c. What is the marginal rate of substitution
for the given utility function? d....

Suppose a firm can manufacture a product using the following
production function:
Q = f (K,L) =
"K0.60
"L0.40
(a) What is the APL when the firm uses 10 units of fixed capital
and 30units of labor?
(b) How does the APL change when the firm uses 100 units of
labor?
(c) Write out an expression for the MPL when capital is fixed
(d) Show that the MPL depends on the amount of labor that is
employed by calculating the...

CAN ANYONE SOLVE THIS BY USING R ? CAN YOU PLEASE NOT USE the
(CORRECT=F FUNCTION) WHEN SOLVING PART B, I AM NOT VERY CLEAR WITH
THAT.
2) From a random sample of 673 items made by a particular
manufacturing process, it is found that 27 are defective.
(a) (1 mark) Find a 99.5% confidence interval for the proportion
of defective items made by the process. (Also include the commands
and output.)
(b) (1 mark) Give the command and output...

1. Answer the questions about the following
function.
f(x) = x + 11 / x - 9
(a) Is the point (4, - 17 /3) on the graph of f?
A. Yes, because substituting x = - 17 / 3 into the given
equation results in 4.
B. Yes, because substituting x = 4 into the given equation
results in - 17 / 3.
C. No, because substituting x = 4 into the given equation does
not result in -...
