Which statements are true about making formatting changes to cells in Excel? (Select all that apply)

Unless you explicitly initialize global variables, they are automatically initialized to

shusha [124]

Answer:

Zero(0)

Explanation:

Global Variables

Variables which are declared outside any function. Any function can use these variables,they are automatically initialized to zero(0).They are generally declared before main() function.

Example- C program for showing global variable is 0.

#include <stdio.h>

int g; // declaring g as global variable

int main()

{

printf("%d",g); //printing global variable

return 0;

}

Output

Paragraph: Read the following two e-mail messages. In three to five sentences, explain why E-mail B is the more appropriate work

exis [7]

E-mail B is the more appropriate workplace e-mail because it’s straightforward, polite, and professional. E-mail A was more accusatory and aggressive, and many people don’t like when they’re being yelled at or accused of something and, as a result, this person may start to dislike that coworker. However, the second e-mail was more polite and made the receiver think of them as a respectful person so that they’re happy to help them out.

Use the single-server drive-up bank teller operation referred to in Problems 1 and 2 to determine the following operating charac

elena-s [515]

Answer:

This question is incomplete, here's the complete question:

1. Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. 3. Use the single-server drive-up bank teller operation referred to in Problems 1 to determine the following operating characteristics for the system: a.) The probability that no customers are in the system. b.) The average number of customers waiting. c.) The average number of customers in the system. d.) The average time a customer spends waiting. e.) The average time a customer spends in the system. f.) The probability that arriving customers will have to wait for service.

Explanation:

Arrival rate \lambda = 24 customers per hour or 0.4 customers per minute

Service rate \mu = 36 customers per hour or 0.6 customers per minute (from problem 1)

a.) The probability that no customers are in the system , P0 = 1 - \lambda / \mu

= 1 - (24/36) = 1/3 = 0.3333

b.) The average number of customers waiting

Lq = \lambda^2 / [\mu(\mu - \lambda)] = 242 / [36 * (36 - 24)] = 1.33

c.) The average number of customers in the system.

L = Lq + \lambda / \mu = 1.33 + (24/36) = 2

d.) The average time a customer spends waiting.

Wq = \lambda / [\mu(\mu - \lambda)] = 24 / [36 * (36 - 24)] = 0.0555 hr = 3.33 min

e.) The average time a customer spends in the system

W = Wq + 1/\mu = 0.0555 + (1/36) = 0.0833 hr = 5 min

f.) The probability that arriving customers will have to wait for service.

= 1 - P0 = 1 - 0.3333 = 0.6667

Write a recursive method called repeat that accepts a string s and an integer n as parameters and that returns s concatenated to

svp [43]

Answer:

public static String repeat(String text, int repeatCount) {

if(repeatCount < 0) {

throw new IllegalArgumentException("repeat count should be either 0 or a positive value");

}

if(repeatCount == 0) {

return "";

} else {

return text + repeat(text, repeatCount-1);

}

Explanation:

Here repeatCount is an int value.

at first we will check if repeatCount is non negative number and if it is code will throw exception.

If the value is 0 then we will return ""

If the value is >0 then recursive function is called again untill the repeatCount value is 0.
