Description: Integer userVal is read from input. Assume userVal is greater than 1000 and less than 99999. Assign onesDigit with userVal's ones place value.
Ex: If the input is 36947, then the output is:
The value in the ones place is: 7

Code:
#include
using namespace std;

int main() {
int userVal;
int onesDigit;

cin >> userVal;

cout << "The value in the ones place is: " << onesDigit << endl;
}

Answers

Answer 1

Use the modulus operator to find the remainder of userVal divided by 10, then assign it to onesDigit variable.

You need to assign the ones place digit of the input value to the variable 'onesDigit'.

You can achieve this by using the modulo operator '%' to get the remainder when 'userVal' is divided by 10.

This will give you the ones place digit.

Here's the modified code:

#include <iostream>

using namespace std;

int main() {

int userVal;

int onesDigit;

cin >> userVal;

onesDigit = userVal % 10;

cout << "The value in the ones place is: " << onesDigit << endl;

}

This code reads an integer 'userVal' from the user and assigns its ones place digit to 'onesDigit'.

Finally, it prints out the result.

Pretend you are planning a trip to three foreign countries in the next month. Consult your wireless carrier to determine if your mobile phone would work properly in those countries. What would the costs be? What alternatives do you have if it would not work?

Answers

Upon consultation with the wireless carrier the repone was that the cost will go up by 25 % of the normal charges. This type of service is called roaming. The alternatives were to purchase new devices and plans compliant with the local network. These in themselves are additional costs and it is much more easier to go with the current provider.

Question (1): The following Boolean expression, Z = (B+C) * A, it represents an Alarm Circuit, where C indicates Door Open Sensor, B indicates Motion Sensor, A indicates Arm Alarm, Z indicates the output is Alarm:

Answers

The complete question may be like

The following Boolean expression represents a security system:

Z = (D * M) + A

Where D represents the Door Sensor, M represents the Motion Sensor, A represents the Arming status, and Z represents the Alarm output.

The question related to this expression for the USA curriculum can be:

Which combination of sensor inputs and arming status will trigger the alarm in the security system?

a) D = 1, M = 0, A = 0

b) D = 0, M = 1, A = 1

c) D = 1, M = 1, A = 1

d) D = 0, M = 0, A = 0

Choose the option that correctly represents the combination of sensor inputs and arming status that will activate the alarm in the security system.

ANS.

The correct Combination of sensor inputs and arming status that will trigger the alarm in the security system can be determined by evaluating the given Boolean expression Z = (D * M) + A. Let's analyze each option and determine the one that activates the alarm:

a) D = 1, M = 0, A = 0:

In this case, D (Door Sensor) is active (1), but M (Motion Sensor) is inactive (0), and A (Arming status) is also inactive (0). The expression evaluates to (1 * 0) + 0 = 0. Since the result is 0, the alarm will not be triggered.

b) D = 0, M = 1, A = 1:

Here, D (Door Sensor) is inactive (0), M (Motion Sensor) is active (1), and A (Arming status) is active (1). The expression becomes (0 * 1) + 1 = 1. The output Z is 1, indicating that the alarm will be triggered in this case.

c) D = 1, M = 1, A = 1:

In this scenario, both D (Door Sensor) and M (Motion Sensor) are active (1), and A (Arming status) is active (1). The expression evaluates to (1 * 1) + 1 = 2. Although the input values are valid, the output Z should be either 0 or 1 according to the Boolean logic. Therefore, this combination does not trigger the alarm.

d) D = 0, M = 0, A = 0:

In this option, both D (Door Sensor) and M (Motion Sensor) are inactive (0), and A (Arming status) is also inactive (0). Similar to option a, the expression evaluates to (0 * 0) + 0 = 0. The alarm will not be triggered.

Based on the analysis, option b) D = 0, M = 1, A = 1 is the correct combination that will activate the alarm in the security system. The combination represents an armed status (A = 1) with the motion sensor (M = 1) detecting movement, indicating a potential security breach.

Answer:identity theft

Explanation:they asked for all of her personal information

Answer:

Identity Theft.
“The bank” asked for all of her personal information.

What is Identity theft?

Identity theft occurs when criminals gain access to enough personal data about a person to carry out a fraud, such as their name, date of birth, and current or past residences. Whether the victim is living or dead, identity theft can happen.

Despite being a frequent precursor to fraud, identity theft is not regarded as a criminal offense. When someone else uses that person's identity for financial benefit, it constitutes a reportable crime. In cases of fraud, the person or business, such as your bank, that has or may have incurred a financial loss as a result of the use of the stolen identity will be deemed the victim of fraud, and you will be considered the victim of identity theft.

Identity theft can result in fraud that directly affects your personal finances. Until the issue is rectified, it may also be challenging for you to get loans, credit cards, or a mortgage.

Explanation:

a. Materials price variance:

Alpha:

Actual quantity purchased and used = 123,200 units

Actual cost = $ 8.70 per unit

Standard cost = $ 9.00 per unit

Price variance = (Actual price - Standard price) x Actual quantity

Price variance = ($ 8.70 - $ 9.00) x 123,200 units

Price variance = -$ 3,696 (Favorable)

Beta:

Actual quantity purchased and used = 222,400 units

Actual cost = $ 12.00 per unit

Standard cost = $ 11.50 per unit

Price variance = (Actual price - Standard price) x Actual quantity

Price variance = ($ 12.00 - $ 11.50) x 222,400 units

Price variance = $ 11,100 (Unfavorable)

Materials efficiency variance:

Alpha:

Actual quantity used = 2,400 units x 48 units per unit of output = 115,200 units

Standard quantity allowed = 2,400 units x 48 units per unit of output = 115,200 units

Efficiency variance = (Standard quantity - Actual quantity) x Standard price

Efficiency variance = (115,200 - 123,200) x $ 9.00

Efficiency variance = -$ 72,000 (Unfavorable)

Beta:

Actual quantity used = 2,400 units x 96 units per unit of output = 230,400 units

Standard quantity allowed = 2,400 units x 96 units per unit of output = 230,400 units

Efficiency variance = (Standard quantity - Actual quantity) x Standard price

Efficiency variance = (230,400 - 222,400) x $ 11.50

Efficiency variance = $ 92,160 (Favorable)

b. Materials mix variance:

Standard mix:

Alpha: 48 / (48 + 96) = 33.33%

Beta: 96 / (48 + 96) = 66.67%

Actual mix:

Alpha: 123,200 / (123,200 + 222,400) = 35.60%

Beta: 222,400 / (123,200 + 222,400) = 64.40%

Mix variance = (Actual mix - Standard mix) x Actual quantity x Standard price

Mix variance = (0.0356 - 0.3333) x 2,400 units x $ 9.00

Mix variance = -$ 14,246 (Favorable)

Materials yield variance:

Standard yield:

Alpha: 2,400 units

Beta: 2,400 units

Actual yield:

Alpha: 123,200 / 48 = 2,566.67 units

Beta: 222,400 / 96 = 2,316.67 units

Yield variance = (Standard quantity - Actual quantity) x Standard price

Yield variance = (2,400 - 2,316.67) x $ 9.00

Yield variance = $ 751.20 (Unfavorable)
