Answer:
The correct answer is:
12 (c)
Explanation:
The codes as shown C8 and D9 represent cells in an Excel spreadsheet. the cell tags describe the column letter and row numbers. For instance; C8 means the 8th row in Column C, while D9 means; the 9th row in column D. In order to do mathematical functions with Excel, the formulae starting with an equal sign (=) like the one shown in this example are used. The function is solved as follows:
= 2*C8+3*D9
where:
* = multiplication sign (×)
C8 = 3
D9 = 2
∴ 2*C8+3*D9 = (2 × 3) + (3 × 2)
= 6 + 6 = 12
∴ the result is 12
Answer:
systematic sampling method
Explanation:
Based on the information provided within the question it can be said that in this scenario the method that was used was a systematic sampling method. This method focuses on selecting elements from a ordered sampling frame, which in this case refers to every 8th chip starting from the 3rd. This method repeats once the end of the list or process is reached which is 140 chips in this scenario.
Answer:
public static int square(int num){
return num*num;
}
Explanation:
Using the Java Programming Language, we declare a function named square as stated in the question, the return type of the function is stated as integer. And the the parameter it receives is an integer number called num.
To get the square of the number we use the expression num*num, and return the the squared value. When the function is called, it will receive one argument (an integer value), it will calculate the square and return it.
Answer:
duplex mode
Explanation:
It is the duplex mode. In this mode, communication is in both directions at the same time. And it is different from the simplex or the semi duplex types in which the communication is one way only or one way at a time only. Thus, duplex mode seems to be requiring more bandwidth certainly but it can be advantageous definitely, and in situations like real tine communication, when we don't have the time and want to send as well receive the message at the same time.
