Financial accounting utilizing U.S. standards has primarily been based on historical cost. In business combinations, book value and carrying value on bonds can become relevant. In addition, fair market value of other assets may also become a factor. Discuss the pros and cons of each method of valuation. Which method do you feel is the best for valuation of assets? Explain in about 100 words and give references

At a certain university, 50% of all entering freshmen planned to major in a STEM (science, technology, engineering, mathematics) discipline. A sample of 36 freshmen is selected. What is the probability that the proportion of freshmen in the sample is between 0.482 and 0.580? Write the answer as a number to the 4th decimal (0.1234).

The intended steps are as follows:

Step 1: Check to see that the conditions np ≥ 10 and n(1− p) ≥ 10 are
both met. If so, it is appropriate to use the normal curve.
Step 2: Find the mean Up and standard deviation ap.
Step 3: Sketch a normal curve and shade in the area to be found.
Step 4: Find the area using the TI-84 PLUS.

  1. A 2 kb fragment of DNA was cut by EcoRI and BamHI and then analyzed by gel electrophoresis. The following fragment sizes were produced:

EcoRI: 900, 700, 400

BamHI: 1100, 900

In order to map the location of each restriction site, each fragment was then digested with the other two restriction enzymes. The following was obtained:

BamHI-Treated

EcoRI-Treated

Original Fragment Size

700, 200

900

EcoRI

400

700, 400

1100

700, 200

900

Based on the fragment size analysis performed above, construct the map of restriction sites for this 2 kb fragment of DNA.

2.     Most restriction enzymes (RE’s) were isolated from bacteria. Since these bacteria require an intact (i.e. undigested) genome in order to survive, what mechanism protects the genomic DNA of bacteria from digestion by their own restriction enzymes?

3. Today we examined the pattern of genomic DNA when it is cut by a restriction enzyme. One of the enzymes, EcoRI, recognizes a specific 6 bp sequence. How often would you expect this enzyme to cut a long stretch of DNA? About how many fragments does an EcoRI digest produce on the calf genome (Bos taurus, 3 x 109 basepairs in length)? Show all work.

4.   There are two principles underlying gel electrophoresis: charge, and the use of a gel matrix. Explain why both of these are necessary to separate DNA by size. Why is charge alone insufficient? Why is a gel matrix without charge insufficient?

5.     Agarose gel electrophoresis can size fractionate DNA fragments. If a 1000 bp linear DNA fragment and plasmid DNA 1000 bp in length are both run on the same gel, will they appear as the same size? Why or why not?

6.    Today we amplified 50 ng of Bos taurus (calf) DNA by PCR. This amount of DNA contains about 15,000 molecules of the insulin gene [50 ng DNA= 2.5 x 10-20 mol; (2.5x10-20 )x(6.023×1023) = 1.5 x 104 molecules]. We performed PCR for 35 cycles to amplify the amount of this gene.

      a. What is the theoretical fold amount of DNA amplified by 35 cycles of PCR (remember the 2N formula)?


      b. How many molecules of the insulin gene would therefore be present after PCR?

7.   In theory, PCR exponentially amplifies a DNA fragment for x number of cycles. However, the concentration of PCR products will usually never reach the theoretical amount of amplification. Why do you think this is the case?

How many iterations of the for loop does this program perform?

int main(void) {
int a[] = {1, 2, 3, 4};
int i;
for (i = 0; i < 4; i++) {
    if (a[i] < 0) return 1;
    else return 0;
}
return 0;
}

Question 1 options:

A

No iterations.

B

The program crashes.

C

One.

D

The program does not compile.

E

Four.

Question 2

What does the following program do?

int main(void) {
  int i, a[];
  a[0]=1;
  for (i=0; i<10; i++) {
    a[i] = a[i-1] + 2*i + 1;
  }
  return 0;
}

Question 2 options:

A

It crashes when it is run because no memory is reserved for the array.

B

It does not compile.

C

It fills the array with the squares of the integers from 1 to 10.

D

It fills the array with the first 10 powers of 2.

Question 3

What's the problem with this code?

int main(void) {
  int i, a[5];
  for (i=1; i <= 5; i++) {
    a[i] = i+1;
  }
  return 0;
}

Question 3 options:

A

The main problem is that the loop accesses a non-existing a[5]. This will cause some memory location to be inadvertently written. The secondary problem is that a[0] is left uninitialized.

B

It doesn't compile because one cannot declare an int variable and an int array on the same line.

C

There is no problem. The code will run just fine.

D

It crashes because a[1] is accessed before a[0].

Question 4

If a is declared with

  int a[10];

what value does sizeof(a) have?

Question 4 options:

A

14

B

Whatever is the size of a pointer to an integer.

C

10

D

10*sizeof(int)

Question 5

What does the following program do?

#include 
int main(void) {
  int a[] = {1,2,3,4};
  int b[4];  b = a;
  printf("%4d\n", b);
  return 0;
}

Question 5 options:

A

It prints 1 2 3 4.

B

The program incurs a segmentation fault when run.

C

It does not compile. You cannot copy arrays like that.

D

It does not compile. You cannot print an entire array like that.

question 6

Arrays are just pointers in disguise.

Question 6 options:

A True
B False

Question 7

Declaring too large an array in a function may cause a stack overflow when the function is called.

Question 7 options:

A True
B False

Question 8

What does the following program do?

int main(void) {
  int a[4];
  a = {1,2,3,4};
  return a[3];
}

Question 8 options:

A

It crashes because main can only return 0.

B

It returns 3.

C

It returns 4.

D

It does not compile.

Question 9

What does the following program do?

#include 

int main(void) {
  int i = 2;
  int a[] = {0,1,2,3,4};
  int n = sizeof(a) / sizeof(a[0]);
  for (i = 0; i < n; i++) {
    (*(a+i))++;
    printf(" %d", a[i]);
  }
  printf("\n");
  return 0;
}

Question 9 options:

A

It does not compile.

B

It prints: 1 1 1 1 1

C

Prints: 1 2 3 4 5.

D

It crashes because it causes a segmentation fault.

Question 10

What does the following program do?

#include 

int main(void) {
  int * p;
  int a[] = {0,1,2,3,4};
  int n = sizeof(a) / sizeof(a[0]);
  for (p = a; p != a+n; p++) {
    printf(" %d", *p);
  }
  printf("\n");
  return 0;
}

Question 10 options:

A

It crashes because p != a+n accesses an address that isout of bounds.

B

It doesn't compile. You cannot assign an array to a pointer because they are of different types.

C

It prints nonsense because %d is for integers, while p is a pointer.

D

It prints: 0 1 2 3 4

C language <stdio.h> (functions)

Write a program to display a table of Fahrenheit temperatures and their equivalent Celsius temperatures. Create a function to do the conversion from Fahrenheit to Celsius. Invoke the function from within a for loop in main() to display the table. Ask the user for a starting temperature and and ending temperature. Validate that the starting temperature is within the range of -100 to 300 degrees, Validate that the ending temperature is in the range of -100 to 300 degrees, and is also greater than the starting temperature. Use a decision inside the ending temperature validation loop to display either the "out-of-range" message or the "greater than starting temperature" message.

The formula for converting a Fahrenheit temperature to Celsius is:
C = (5 / 9) * (F - 32)
Use this exact formula - do not pre-calculate 5/9 as .56 (you will have to type cast one of the numbers to a double for the equation to work correctly).

Format the Celsius temperatures to 1 decimal place.

Example Run #1:
(bold type is what is entered by the user)

Enter a starting Fahrenheit temperature: -200
The starting temperature must be between -100 and 300 degrees.
Please re-enter the starting temperature: 0
Enter an ending Fahrenheit temperature: 500
The ending temperature must be between -100 and 300 degrees.
Please re-enter the ending temperature: -20
The ending temperature, -20, must be greater than the starting temperature.
Please re-enter the ending temperature: 20
