A new computer virus attacks a folder consisting of 200 files. Each file gets damaged with probability 0.2 independently of other files. What is the probability that fewer than 50 files will get damaged? g

Answers

Answer 1

Answer:

0.95345

Explanation:

Given that :

Number of files (n) = 200

Probability of getting damaged (p) = 0.2

q = 1 - p = 1 - 0.2 = 0.8

using normal approximation:

Mean (m) = np = 200 * 0.2 = 40

Standard deviation (s) = √n*p*q= √(200 * 0.2 * 0.8) = 5.6568542

P(X < 50)

X = 50 - 0.5 = 49.5

Find the standardized score :

Z = (x - m) / s

Z = (49.5 - 40) / 5.6568542

Z = 9.5 / 5.6568542

Zscore = 1.6793786

P(Z < 1.6793) = 0.95345 ( using Z probability calculator)

4.20 [5] <§4.5> Add NOP instructions to the code below so that it will run correctly on a pipeline that does not handle data hazards. ADDI X1, X2, #5 ADD X3, X1, X2 ADDI X4, X1, #15 ADD X5, X3, X2

Answers

Answer:

Following are the solution to this question:

Explanation:

The following is the sequence of instructions to ensure proper implementation after adding NOPs:  

[tex]ADDI \ Xl,X2, \#5\\NOP\\NOP\\NOP\\ADD \ X3, X1,X2\\ADDI \ X4, X1, \#15\\ADD \ X5, X3,X2\\[/tex]

The value of the X1 is identified in the first ADDI order X1, X2, #5, mostly on the WB level, which appears in clock cycle five. Before the second instructions, three NOPs are added because as second instruction should wait for X1 to be correct.

Its second primary example with cycle 5, but ends through cycle 9. clock. Since X3 quality doesn't execute its third command, no NOP is inserted.

Its third instruction begins at clock cycle 6 and finishes at clock cycle 10. Because the fourth order is not required to execute an X4 value, no NOP is inserted, and the fourth instruction begins in cycle 7 and finishes at clock cycle 11.

2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday
present. They will show they are done by entering the word "done."
a- for
b- while

Answers

Answer:

1. Option A: for loop is correct

2. Option B: while loop is correct

Explanation:

Two loops are used commonly. For and while

For is used when the number of iterations are already known and while is used when number of iterations is not known and the loop has to be terminated based on any condition.

1. You are finding the batting average of 13 baseball players.

For loop will be used as the number of iterations is already known. The score of 13 players has to be used to calculate the average so there will be 13 iterations. Hence, for loop will be used.

2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday  present. They will show they are done by entering the word "done."

While loop will be used as the termination of loop depends on the input given by the user so the number of iterations are not already known.

Hence,

1. Option A: for loop is correct

2. Option B: while loop is correct

Answer: 1.for 2. while

Program Explanation:

Import package.Defining the main class.Defining the main method.Inside the main method two string "f,s" is declared that uses input method to input value.After input value multiple conditional statement is declared that checks inputs value.In the if block, it checks first string value equal to second value, if it is true it will print a message "Great!".In the else if block it checks string value that has same length, for this it uses "l" variable that checks length value, and the print the message "Close enough".In the else block, it will print the message "Try again".

A digital computer has a memory unit with 26 bits per word. The instruction set consists of 756 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. a. How many bits are needed for the opcode? b. How many bits are left for the address part of the instruction? c. What is the maximum allowable size for memory? d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Answers

Answer:

a. the number of bits needed for the opcode = 10

b. address part is = 16 bits

c. maximum allowable size of memory = 65536

d. Maximum memory size per word = 67108864

Explanation:

The memory size of the instruction set is 756 which is less than 2^10 (that is 1024).

Since the word size is 26 bits and the instruction takes 10, the remaining 16 is for the address part which is 65536 memory address. The maximum number of memory size for a word is 67108864.

What is net pay?
What is net pay?

Answers

Answer:

Net pay is an employee’s earnings after all deductions are taken out. Obligatory deductions such as the FICA mandated Social Security tax and Medicare are withheld automatically from an employee’s earnings. Other deductions come in the form of benefits, which may be optional. Health, dental and vision insurance, life insurance, or a retirement fund may be offered through an employer. These costs will come in the form of a deduction from the employee’s gross pay, or salary.

Net pay refers to the amount an employee takes home, not the amount it cost to employ them. Retirement plan contributions, employee benefits, and employer FICA taxes are deducted before an employee receives their net pay.
