Answer:
import java.util.Scanner; public class Salesman2 {
public static void main(String[] args) { // TODO Auto-generated method stub double CommissionRate;
double TotalSales, Commission;
Scanner Read = new Scanner (System.in); System.out.println("Please enter total sales "); TotalSales=Read.nextDouble();
if (TotalSales<500)
CommissionRate=0.0;
else if (TotalSales>=500 && TotalSales <1000) CommissionRate=0.05;
else
CommissionRate=0.08;}
Commission = CommissionRate * TotalSales;
System.out.println("The Commision is: "+ Commission); }
}
}
Answer:
115200000 bits
Explanation:
Given Data:
Total Time = 3 minute = 3 x 60 sec = 180 sec
Sampling rate = 40,000 bits / sample
Each sample contain bits = 16 bits /sample
Total bits of song = ?
Solution
Total bits of song = Total Time x Sampling rate x Each sample contain bits
= 180 sec x 40,000 bits / sec x 16 bits /sample
= 115200000 bits
= 115200000/8 bits
= 14400000 bytes
= 144 MB
There are total samples in one second are 40000. Total time of the song is 180 seconds and one sample contains 16 bits. so the total bits in the song are 144 MB.
