The guy named Kirby didn't touch the power button on the projector. If he touched means the projector will work fine.
<u>Explanation</u>:
- Kirby touched the gear on the projector. He should check the projector carefully before operating the projector. But he didn't check properly.
- There was a blue rip in the projector. Kirby fails to notice the blue rip. Without minding that he has started the projector. So the tape and the projector is not working well.
- He should fix the blue rip and he should press the start button in the projector. The mistake is he didn't do that. This is the thing that made the projector ripped.
Answer:
The power is 
Explanation:
In order to obtain the power it consumes we need to first obtain the resistance of the hair dryer at 120 V

Now the power supplied in Europe at their voltage of 230V would be

Looking the power obtain we see that it is higher than 1530 W so this would cause the dryer to smoke.
Answer:
Distribution (or its more sophisticated counterpart, supply chain management) can add value to goods and services by making them more easily and conveniently available to consumers. ... This means that you need good wholesalers and good transportation systems to get your products to the retailers.

Answer:
The solution code is given below
- using System;
- using System.Linq;
-
- public class Program
- {
- public static void Main()
- {
- string[] letters = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T","U", "V", "W", "X", "Y", "Z"};
-
- Console.WriteLine("Please input a letter: ");
- string input_letter = Console.ReadLine();
-
- if(letters.Contains(input_letter)){
- Console.WriteLine("OK");
- }else{
- Console.WriteLine("Error. Not uppercase letter.");
- }
- }
- }
Explanation:
Firstly we import the necessary libraries, System and Linq (Line 1-2).
Next we create a string array to hold all uppercase letters (Line 8).
Next, we prompt user to input a letter using the ReadLine() method (Line 10 - 11)
At last, we define if and else conditions to check if the letters contains the input letter. If so, print ok else print an error message. (Line 13-17)
Answer:
![\left[\begin{array}{ccccc}&DF&SS&MS&F\\Regression&1&7200&7200&72\\Error&18&1800&100\\total&19&900\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccccc%7D%26DF%26SS%26MS%26F%5C%5CRegression%261%267200%267200%2672%5C%5CError%2618%261800%26100%5C%5Ctotal%2619%26900%5Cend%7Barray%7D%5Cright%5D)
Explanation:
Sample size, n=20
Degrees of freedom is 1
Number of degrees of freedom for error is n-2 hence 20-2=18
Total number of degrees of freedom is 18+1=19
Standard error estimate is
Here,
Coefficient of determination
Here,
The total sum of squares is
SS total=SSR+SSE=7200+1800=9000
MSR=SSR=7200
F value is given by
The ANOVA table is then
