Write a method named isNumericPalindrome that accepts an integer parameter named num. If num is a palindrome the method must return true. Otherwise the method must return false. You can assume as a precondition that num has exactly 5 digits (i.e. it is between 10000 and 99999.) For example, 12321 is a palindrome while 12231 isn't because it's the same number if reversed. public boolean isNumericPalindrome(int num)
Answer:
Explanation:
The following code is written in Java. It is a method that reverses the number that is passed as an argument and compares it to its original version. Then it finally returns the results of the comparison as a boolean (either True or False). Two test cases have been created and can be seen in the attached image below.
public static boolean isNumericPalindrome(int num) {
String numString = Integer.toString(num);
String reversed = "";
for (int i = numString.length()-1; i >= 0; i--) {
reversed += numString.charAt(i);
}
return numString.equals(reversed);

Draw a circuit with a 12-volt battery, a 100 ohms resistor in series, and two resistors (each of value 200 ohms) in parallel. What is the total resistance of the circuit?
Answer:
200 Ω
Explanation:
Hi there!
Please see below for the circuit diagram.
1) Find the total resistance of the resistors in parallel
Total resistance in parallel equation: [tex]\frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2}[/tex]
Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:
[tex]\frac{1}{R_T} = \frac{1}{200} +\frac{1}{200}\\\frac{1}{R_T} = \frac{1}{100}\\R_T=100[/tex]
Therefore, the total resistance of the resistors in parallel is 100 Ω.
2) Find the total resistance of the circuit
Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:
100 Ω + 100 Ω = 200 Ω
Therefore, the total resistance of the circuit is 200 Ω.
I hope this helps!

A government agency is getting rid of older workstations. The agency will donate these workstations, along with other excess computer systems, to nearby schools. Management reminds the systems administrators about the data sanitization and disposal policy. What policy items are applicable for these IT systems, prior to donating to the schools
The "DoD Standard" is a term used during the data sanitizing industry and refers to DoD 5220.22-M, and the further discussion can be defined as follows:
The simplest ways are being used to help eliminate the previously stored data, by deleting hard disc storage facilities with the same data wherever that used a sequence of all zeros.The sparging eliminates statistics to entirely delete the gravitational flux from electronic media. Hard drives as well as other data storage devices, for example, computer tapes, retain magnetic data. It could no longer be seen as storage after a disk is degaussed.Therefore, the final answer is "Using the DoD 5220.22-M method and Degauss media with a magnet".

What should you do if your engine stalls while you are driving?
A: Hold your steering wheel tightly(power steering is difficult)
B: Shift your transmission to neutral
C: Try to re-start; if unable, stop off road, using four-way flashers
D: All of the above
Answer:
D
Explanation:
All of the above should you do if your engine stalls while you are driving. Thus option D is correct.
What is driving?Driving, which includes operating and moving a vehicle in a controlled manner, includes using a car, scooter, truck, vehicle, or scooter. Drivers must abide by the local highway and traffic rules in order to be allowed to drive on city roads, which is contingent upon a number of requirements being completed.
In most situations, you'll lose auto steering whenever the engine shuts off, making it challenging to spin the wheel, as well as power brakes will shortly follow.
Although it takes significantly more pressure, you could still steer but instead, stop. Put the gearshift in neutral. If you can't restart, stop off the road and use your 4 blinkers. Therefore, option D is the correct option.

Your company is a small start-up that has leased office space in a building shared by other businesses. All businesses share a common network infrastructure. A single switch connects all devices in the building to the router that provides internet access. You would like to make sure that your computers are isolated from computers used by other companies. Which feature should you request to have implemented
Answer:
VLAN
Explanation:
In this specific scenario, you should request that a VLAN is implemented at the location. This is a feature that allows you to connect a group of computers to the same network but at the same time make sure that your computers are separate from other groups of computers in the network. This acts as an entire LAN network with specific protection for each group of connected devices. This allows you to pick and choose which groups get allowed access and which ones are isolated from your network.

A test case has been created in the main method which creates a Rectangle object and prints out the printInfo which calls the area and perimeter methods as well. The output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.
Assume X and Y are indepndent. Assume that X has mean 10 and standard deviation 8. Assume Y has mean 12 and standard deviation 6. What is the standard deviation of the variable Z = X + Y. a. 8 b. 6 c. 10 d. 12
Answer:
[tex]\sigma_z = 10[/tex]
Explanation:
Given
[tex]\bar x = 10[/tex]
[tex]\sigma_x = 8[/tex]
[tex]\bar y = 12[/tex]
[tex]\sigma_y = 6[/tex]
[tex]z = x + y[/tex]
Required
[tex]\sigma_z[/tex]
This is calculated as:
[tex]\sigma_z = \sqrt{Var(x) + Var(y)}[/tex]
Calculate [tex]Var(x)[/tex]
We have:
[tex]Var(x) = \sigma_x^2[/tex]
[tex]Var(x) = 8^2[/tex]
[tex]Var(x) = 64[/tex]
Calculate [tex]Var(y)[/tex]
We have:
[tex]Var(y) = \sigma_y^2[/tex]
[tex]Var(y) = 6^2[/tex]
[tex]Var(y) = 36[/tex]
So, we have:
[tex]\sigma_z = \sqrt{Var(x) + Var(y)}[/tex]
[tex]\sigma_z = \sqrt{64 + 36}[/tex]
[tex]\sigma_z = \sqrt{100}[/tex]
[tex]\sigma_z = 10[/tex]

cual es el procedimientos para asistir en el transporte publico a personas discapacitadas
Answer:
Una discapacidad física o motora en una o más partes del cuerpo obstaculiza las acciones y / o movimientos de la persona con discapacidad. La discapacidad puede surgir porque las partes del cuerpo no han crecido completamente o están dañadas (anomalías físicas) o porque las funciones físicas están alteradas (anomalías funcionales).
En la mayoría de los casos, se proporciona una ayuda a las personas con discapacidades físicas graves para que puedan desenvolverse más fácilmente en la sociedad. Alguien con una discapacidad motora severa en las piernas a menudo usa una silla de ruedas. Las personas con una discapacidad motora de las manos (pérdida de la motricidad fina) o de los brazos pueden compensar esto con un manipulador o ayudas especializadas en tareas, como un dispositivo para comer o un dispositivo para girar las hojas.
Así, todos estos elementos deben ser posibles de ser insertados en los medios de transporte público como forma de ayudar a estas personas a trasladarse por estos medios, es decir, los autobuses, trenes, etc., deben estar adaptados para poder recibir allí a pasajeros en sillas de ruedas o con necesidades motoras especiales.
