CTL + E to activate the search contacts box.

advanced Find under the Search tab.

Explanation:

An Outlook user can search for contacts through the following ways:

• the Search bar located above the list of contacts.

• the Search People bar on the Find command group.

• the Search People located on the People navigation icon.

• CTL + E to activate the search contacts box.

• advanced Find under the Search tab.

Therefore, the correct options are A, B, C, D and E.

Answer:

The correct statement regarding DCE and DTE interfaces is:

c. DTE and DCE describes the interface and direction of data flow between devices; a single device may have both types of interfaces.

Explanation:

DTE stands for Data Terminal Equipment.  It is a device that initiates or controls a device's serial connection. The term DCE stands for Data Communications Equipment.  It is a device that is used to a modem or other communication interfaces to the DTE device.  DTE is a communication receptor, while DCE is a communication broadcaster or distributor.

Answer:

Explanation:

The following code is written in Java. It creates the Rainfall class with two constructors, one that passes the entire array of rainfall and another that initializes an array with 0.0 for all the months. Then the class contains a method to add rain to a specific month, as well as the three methods requested in the question. The method to add rain validates to make sure that no negative value was added. 8 Test cases were provided, and any methods can be called on any of the 8 objects.

class Brainly {

   public static void main(String[] args) {

       Rainfall rain1 = new Rainfall();

       Rainfall rain2 = new Rainfall();

       Rainfall rain3 = new Rainfall();

       Rainfall rain4 = new Rainfall();

       Rainfall rain5 = new Rainfall();

       Rainfall rain6 = new Rainfall();

       Rainfall rain7 = new Rainfall();

       Rainfall rain8 = new Rainfall();

   }

}

class Rainfall {

   double[] rainfall = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0};

   public Rainfall(double[] rainfall) {

       this.rainfall = rainfall;

   }

   public Rainfall() {

   }

   public void addMonthRain(double rain, int month) {

       if (rain > 0) {

           rainfall[month-1] = rain;

       }

   }

   public double totalRainfall() {

       double total = 0;

       for (double rain: rainfall) {

           total += rain;

       }

       return total;

   }

   public double averageRainfall() {

       double average = totalRainfall() / 12;

       return average;

   }

   public double rainiestMonth() {

       double max = 0;

       for (double rain : rainfall) {

           if (rain > max) {

               max = rain;

           }

       }

       return max;

   }

}

Answer:

Static variables are initialized only once

Explanation:

Only one copy of static variables are created when 10 objects are created of a class

A static variable is common to all instances of a class because it is a class level variable

Answer:

The important problem is explained in the next section of clarification.

Explanation:

The longer it is required for a computing device interrupt to have been performed when it is created, is determined as Interrupt latency.

The accompanying duties include interrupt transmission delay or latency are provided below:

Explanation:

In the backward chaining technique, used by the inference engine component of an expert system, the expert system starts with the goal, which is the then part,

Backward chaining is the process of working backward from the goal. It is used s an artificial intelligence application and proof application. The backward chaining can be implemented in logic programming.

Hence the then part is the correct answer.
