OMR, OCR and MICR are all types of character and mark recognition devices. They are scanners that are able to recognize special characters and marks.
OMR stands for Optical Mark Recognition,which senses the presence or absence of a mark.
OCR stands for Optical Character recognition, which reads special preprinted characters by light source.
MICR stands for Magnetic Ink Character Recognition, where machine reads character made of ink containing magnetized particles.

Prove that any amount of postage greater than or equal to 64 cents can be obtained using only 5-cent and 17-cent stamps?

elixir [45]

Let P(n) be "a postage of n cents can be formed using 5-cent and 17-cent stamps if n is greater than 63".Basis step: P(64) is true since 64 cents postage can be formed with one 5-cent and one 17-cent stamp.Inductive step: Assume that P(n) is true, that is, postage of n cents can be formed using 5-cent and 17-cent stamps. We will show how to form postage of n + 1 cents. By the inductive hypothesis postage of n cents can be formed using 5-cent and 17-cent stamps. If this included a 17-cent stamp, replace this 17-cent stamp with two 5-cent stamps to obtain n + 1 cents postage. Otherwise, only 5-cent stamps were used and n 65. Hence there are at least three 5-cent stamps forming n cents. Remove three of these 5-cent stamps and replace them with two 17-cent stamps to obtain n + 1 cents postage.Hence P(n + 1) is true.

Write a public static method named printArray, that takes two arguments. The first argument is an Array of int and the second ar

Serjik [45]

Answer:

Written in Java

public static void printArray(int myarr[], String s){

for(int i = 0; i<myarr.length;i++){

System.out.print(myarr[i]+s);

}

Explanation:

This defines the static method alongside the array and the string variable

public static void printArray(int myarr[], String s){

The following iteration iterates through the elements of the array

for(int i = 0; i<myarr.length;i++){

This line prints each element of the array followed by the string literal

System.out.print(myarr[i]+s);

}

The method can be called from main using:

printArray(myarr,s);

Where myarr and s are local variables of the main

What is the name of the item that supplies the exact or near exact voltage at the required wattage to all of the circuitry insid

gizmo_the_mogwai [7]

Answer:

It's the power supply

Explanation:

The power supply is what essentially enables the computer to operate. It is able to do that by converting the incoming alternating current (AC) to direct current (DC) at the correct wattage rating that is required by the computer to function. The power supply is a metal box that is generally placed in the corner of the case.

Which formula would you enter into C3, and then AutoFill into C4 through C6, to calculate the percent sales (Pct.) for the regio

inna [77]

Answer:

In C3, you would enter the formula:

=B3/$B$7%

Explanation:

Let's assume the first row is 1 and it contains the titles of the columns. For instance, the content of the cellss A1:C1 could be:

A1: Region

B1: Sales

C1: Percent Sales

Also, assume the second row is empty and the cells on the first column, A, contain the names of four regions. For instance, North, South, East, and West:

A3: North

A4: South

A5: East

A6: West

The cells B3:B6 contain the sales for the four regions. For instance:

B3: 200

B4: 300

B5: 100

B6: 400

Then, you must calculate the percent sales for every region, in the cells C3:C6.

That means, you must divide the sale of every region by the total of sales and multiply by 100.

To do that in the worksheet you do this:

1. Sum the sales for the regions:

In cell B7 introduce: =SUM(B3:B6)

2. Calculate the percent sale for the first region:

In cell C3 introduce: =B3/$B$7%

That means that the reference B3 is relative: when you copy that formula, the column (B) and the row (3) will change accordingly to the cell where you will copy it.

Thus, by using the Autofill into C4 through C6, the column wil remain unchanged (C) and the row will change to 4, 5, and 6, respectively.

The symbol $ used in $B$7 make the reference absolute. That means that they will not change. The symbol % makes that the result is multiplied by 100.

3. When you use Autofull into C4 through C6, you obtain:

C4: =B4/$B$7%

C5: =B5/$B$7%

C6: =B6/$B$7%
