A set of parity-check equations for a distance-4 Hamming code
with 64 data bits and 8 parity-check bits are specified by the
eight 72-bit constants below, each representing one row the
parity-check matrix:
C[1] = 72'h80000000000000007f; C[2] =
72'h400000003FFFFFFF80;
C[3] = 72'h20001FFFC0007FFF80; C[4] = 72'h100FE03FC07F807F80;
C[5] = 72'h0871E3C3C78787878F; C[6] = 72'h04B66CCCD9999999B3;
C[7] = 72'h02DAB5556AAAAAAAD5; C[8] = 72'hFFFFFFFFFFFFFFFFFF;
Assuming that bits are numbered D[17:0],
bits D[71:64] are the check bits, D[63:0] are the data bits.

(In c code only, not c++)
We will simulate the status of 8 LEDs that are connected to a
microcontroller. Assume that the state of each LED (ON or OFF) is
determined by each of the bits (1 or 0) in an 8-bit register
(high-speed memory).
Declare a char variable called led_reg and
initialize it to 0.
Assume that the least-significant bit (lsb) controls LED#0 and the
most-significant bit (msb) controls LED#7.
In the main function, build and present a...

Find the 2's complement of the following decimal numbers (You
must convert the number to binary and the answer has to be in
binary with the same number of bits as the conversion)?
a. 20
b. 15
c. 2126
d. 266
e. 466
please explain how you did it!

Suppose you just obtained data from a survey in which
you learned the following information about 50 individuals: age,
income, marital status, number of vehicles in the household. For
each variable you will be asked to answer the following 2
questions:
1. State the type of data (quantitative and continuous,
quantitative and discrete, or qualitative)
2. State the type of graphical summary you might be able to draw to
provide a visual summary of the data. You do not need...

Write a function to calculate the sum of cubes from 1 to
n, but skip the multiple of 5. Say, if n=10, the result is
1^3+2^3+3^3+4^3+6^3+7^3+8^3+9^3. The input is the value of n, the
output is the summation. (you need if statement to check whether a
number is a multiple of 5.In R, a%%b is the remainder for a divided
by b. So, we have 10%%5=0)

Using R and the data in the table below, perform the regression
of D on C (i.e., report the regression equation).
Hint: The code to enter the vectors C and D into R is: C <-
c(3, 6, 8, 9, 1, 3) D <- c(2, 7, 5, 4, 0, 4)
