Consider an Erlang loss system. The average processing time is 3 minutes. The average inter-arrival time is 3 minutes. The number of servers is 3. What is r (sometimes referred to as the offered load)
Answer:
r = 1
Explanation:
Average processing time ( p ) = 3 minutes
Average inter-arrival time ( a ) = 3 minutes
number of servers ( m ) = 3
Determine the value of r
r ( offered load ) = p/a
= 3 / 3 = 1
∴ value of r ( offered load ) = 1

How to create a network of relevant prospects?
Answer:
By connecting with industry-specific and relevant prospects.
Now with 760 million+ people, how can you find the most relevant people to connect with? The answer is: With the help of LinkedIn automation tools.
There are a number of best LinkedIn automation tools that come with advanced search filters to help you refine your target audience. These LinkedIn automation tools have special operators that help users find and reach even the most difficult leads.
However, there is a drawback. These LinkedIn automation tools can cause spam if you send thousands of connection requests or messages in a short time.
Moreover, if you send templated connect notes or messages, you’re likely to get a very low or almost zero acceptance and response rate.

Write an algorithm to find the sum of the following series:
a) 1+x+x^2+x^3+...+x^20
b) 1-x+x^2-x^3+...+x^20
c) 1+x/2+(x²)/3+(x^3)/4+...+(x^20)/21
Answer:
The algorithm is as follows:
Input x
sum_a = 0
sum_b = 0
sum_c = 0
for i = 0 to 20
sum_a = sum_a + x^i
sum_b = sum_b + (-x)^i
sum_c = sum_c + x^i/(i+1)
print sum_a, sum_b, sum_c
Explanation:
Required
An algorithm to solve (a), (b) and (c)
For Series (a):
This series is a geometric progression and the common ratio is x
i.e.
[tex]r = x/1 = x^2/x = ...... = x^{n+1}/x^n =x[/tex]
So, the sum of the series is:
Sum = Previous Sums + x^i --- where i is between 0 and 20 (inclusive)
For Series (b):
This series is a geometric progression and the common ratio is -x
i.e.
[tex]r = -x/1 = -x^2/x = ...... = -(x^{n+1}/x^n) = -x[/tex]
So, the sum of the series is:
Sum = Previous Sums + (-x^i) --- where i is between 0 and 20 (inclusive)
For Series (c):
This series is a neither arithmetic nor geometric progression.
It obeys the following rule:
[tex]\frac{x^i}{1+i}[/tex] --- where i is between 0 and 20 (inclusive)
So, the sum of the series is:
Sum = Previous Sums + [tex]\frac{x^i}{1+i}[/tex]

Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.
Answer:
Explanation:
The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.
from random import randint
import numpy as np
test_scores = []
for x in range(200):
test_scores.append(randint(55, 99))
sorted_test_scores = sorted(test_scores)
count = 0
print("Scores in Rows of 10: ", end="\n")
for score in sorted_test_scores:
if count < 10:
print(str(score), end= " ")
count += 1
else:
print('\n' + str(score), end= " ")
count = 1
mean = np.mean(sorted_test_scores)
variance = np.var(sorted_test_scores, dtype = np.float64)
median = np.median(sorted_test_scores)
print("\n")
print("Mean: " + str(mean), end="\n")
print("Variance: " + str(variance), end="\n")
print("Median: " + str(median), end="\n")

Write a program that takes a date as input and outputs the date's season. The input is an integer to represent the month and an integer to represent the day. Ex: If the input is: 4 11 the output is: spring In addition, check if both integers are valid (an actual month and day). Ex: If the input is: 14 65 the output is: invalid The dates for each season are: spring: March 20 - June 20 summer: June 21 - September 21 autumn: September 22 - December 20 winter: December 21 - March 19
Answer:
Explanation:
The following program is written in Java. It is a function that takes in the two parameters, combines them as a String, turns the combined String back into an integer, and uses a series of IF statements to check the parameters and determine which season it belongs to. Then it prints the season to the screen. The code has been tested with the example provided in the question and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
getSeason(4, 65);
getSeason(4, 11);
}
public static void getSeason(int month, int day) {
String combined = String.valueOf(month) + String.valueOf(day);
int combinedInt = Integer.parseInt(combined);
if ((month > 0 && month < 12) && (day > 0 && day < 31)) {
if ((combinedInt >= 320) && (combinedInt <= 620)) {
System.out.println("The Season is Spring");
} else if ((combinedInt >= 621) && (combinedInt <= 921)) {
System.out.println("The Season is Summer");
} else if ((combinedInt >= 922) && (combinedInt <= 1220)) {
System.out.println("The season is Autumn");
} else {
System.out.println("The Season is Winter");
}
} else {
System.out.println("Invalid date");
}
}

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer
Answer:
c. Copy the executable file to the user’s computer
Explanation:
When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.
To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.
The program will work fine without errors.
However, do not mistake the executable file for the source file. The source file ends in .cpp.
