Answer:
CER
Explanation:
The CER refers to equanimity between an identification technology's False Acceptance Rate and its False Rejection Rate, which is “the best summary measure of face recognition technologies' efficacy,” according to a statement from Applied Recognition.
Answer:
One of the strategies to avoid nested conditional is to use logical expressions such as the use of AND & operator.
One strategy is to use an interface class with a method. That method can be created to be used for a common functionality or purpose. This is also called strategy design pattern. You can move the chunk of conditional statement to that method. Then each class can implement that interface class and use that shared method according to their own required task by creating objects of sub classes and call that common method for any such object. This is called polymorphism.
Explanation:
Nested conditionals refers to the use of if or else if statement inside another if or else if statement or you can simply say a condition inside another condition. For example:
if( condition1) {
//executes when condition1 evaluates to true
if(condition2) {
//executes when condition1 and condition2 evaluate to true
} else if(condition3) {
//when condition1 is true and condition3 is true
} else {
//condition1 is true but neither condition2 nor conditions3 are true
} }
The deeply nested conditionals make the program difficult to understand or read if the nested conditionals are not indented properly. Also the debugging gets difficult when the program has a lot of nested conditionals.
So in order to avoid nested conditionals some strategies are used such as using a switch statement.
Here i will give an example of the strategies i have mentioned in the answer.
Using Logical Expressions:
A strategy to avoid nested conditionals is to use logical expressions with logical operators such as AND operator. The above described example of nested conditionals can be written as:
if(condition1 && condition2){ //this executes only when both condition1 and condition2 are true
} else if(condition1 && condition3) {
this executes only when both condition1 and condition3 are true
} else if(condition1 ){
//condition1 is true but neither condtion2 nor condtion3 are true }
This can further be modified to one conditional as:
if(!condition3){
// when condition1 and condition2 are true
}
else
// condition3 is true
Now lets take a simple example of deciding to go to school or not based on some conditions.
if (temperature< 40)
{
if (busArrived=="yes")
{
if (!sick)
{
if (homework=="done")
{
printf("Go to school.");
}
}
}
}
This uses nested conditionals. This can be changed to a single conditional using AND logical operator.
if ((temperature <40) && (busArrived=="yes") &&
(!sick) && (homework=="done"))
{ cout<<"Eligible for promotion."; }
The second strategy is to use an interface. For example you can
abstract class Shape{
//declare a method common to all sub classes
abstract public int area();
// same method that varies by formula of area for different shapes
}
class Triangle extends Shape{
public int area() {
// version of area code for Triangle
return (width * height / 2);
}
}
class Rectangle extends Shape{
public int area() {
// version of area code for Rectangle
return (width * height)
}
}
// Now simply create Rectangle or Triangle objects and call area() for any such object and the relevant version will be executed.

Answer: An objective function in linear programming is a decision variable.
Explanation: An objective function is a function which has the target towards the model whether it should be maximized or minimized according to the relation between the variables present in the function. There are set of variables which are responsible for the controlling of objective function that is known as decision variables.
As a technician, since you have been tasked with increasing the ram memory on a laptop by adding a so-dimm module to an empty memory slot. The process that seats the module in the slot is option D:
The processor, RAM, and computer memory all have an impact on how quickly your laptop operates. The pace increases as each number increases. For example, 4GB of RAM operates more quickly than 2GB. A 2 GHz machine will operate more quickly than a 1 GHz one since processor speed is measured in gigahertz.
Therefore, One application may run on this much memory. If your computer only has 4 GB of RAM, upgrading it would significantly enhance performance. 4-6 GB: The typical user's chores, including as web browsing, working with Word documents, and emailing, will be easily handled by this normal RAM amount.

See options below
Which of the following processes will seat the module in the slot?
Slide the memory into the external Expresscard slot horizontally until the card is even with the laptop case and you hear a click.
Add the mounting pegs to the side of the memory module. Attach the ribbon cable and press into place until the mounting clips catch the mounting pegs.
Align the notch on the long side of the memory module with the rise in the memory slot. Insert the module pins into the slot at a 90-degree angle to the motherboard and press down until the side hold-down clips snap into place.
Align the notch on the long side of the memory module with the rise in the memory slot. Insert the module pins into the slot at a 45-degree angle. Rotate the module by pressing down until the side hold-down clips snap into place.

Explanation:
A communicator is an individual who is obligated to clearly present information to an audience. There are two set of quality a communicator must have to win the trust of the audience, they are, the communicator must be prepared and ethical.
A prepared communicator must learn to organise his oral or written skills, must articulate very word and meaning of expression (clear) and a information must be brief and meaningful.
An ethical communicator must be impartial, trustworthy, respectful and must practice the golden rule. The information they give should help in making proper decisions to situations.
