Answer:
D. Hardware.
Explanation:
The five-component model of a computer system is a conceptual model that describes the five main components of a computer system: hardware, software, data, procedures, and people.
Hardware refers to the physical components of a computer system, including the central processing unit (CPU), memory, storage, and input/output devices. Hardware is the easiest component of the five-component model to change, as it can be upgraded or replaced as needed.
Software refers to the programs and applications that run on a computer system. Software is relatively more complex to change than hardware as it requires specialized skills and knowledge.
Procedures refer to the standard operating procedures and processes that are used to operate and maintain a computer system. Procedures are relatively more complex to change than hardware as it requires specialized skills and knowledge.
Data refers to the information that is stored on a computer system. Changing data requires a more complex process than changing hardware.
People refer to the users, operators, and administrators of a computer system. Changing people's behavior and knowledge is relatively more complex than changing hardware

What is expected value theory?Expected value theory is a subfield of decision theory that examines the likelihood and anticipated outcomes of specific decisions. It is based on the idea that decisions are made based on the probabilities and expected outcomes of those outcomes.
Instead of focusing on the actual outcome of a decision, this theory emphasizes the expected outcome. It attempts to determine the expected value of a decision by first calculating the probability of various outcomes.
The total expected benefit or cost of a decision, taking into account all of the possible outcomes and their probabilities, is known as the expected value.
An illustration of expected value theory is this question.
The maximum number of repairs (333) is multiplied by the cost of repairs ($200 ) to get the expected value in this example.
As a result, the retailer anticipates paying a total of $200 (200 ×333) for repairs, or $66,600

Is is known that a current of 0. 200 a flows through a resistor when a voltage of 5. 00 v is applied across it. What is the resistance of this resistor?.
The resistance of the resistor is 25 Ohms when the current of 0. 200 a flows through a resistor when a voltage of 5. 00 v is applied across it.
Calculating :The equations above are mathematical expressions of this relationship.
V = I x R
I = V / R
R = V / I
In this case, the voltage is 5.00 V and the current is 0.200 A. By rearranging Ohm's Law, we can calculate the resistance of the resistor as follows:
R = V/I
R = 5.00 V / 0.200 A
R = 25 Ohms
What does it mean to resist?The opposition a substance provides to the flow of electric current is known as resistance. The standard unit of resistance is the ohm, which is sometimes written as a word and sometimes symbolized by the uppercase Greek letter omega. It is represented by the capital letter R.
What is Ohm's law?Ohm's law is one of the most fundamental and significant laws governing electric circuits. Under all physical conditions and temperatures remaining constant, Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.

By positioning the operations from left to right
To change the evaluation order, enclose the part of the formula that must be calculated first in parenthesis.
What exactly are parentheses in an Excel formula?If you want to change the order of an operation, use parentheses (). When you use parentheses, Excel is forced to calculate the values contained within the parentheses before calculating the rest of the formula. All operations enclosed in parentheses or brackets are solved first. Come second to solve any exponents. Third, the order in which we always multiply and divide is from left to right. Fourth, we work our way through each addition and subtraction problem from left to right.
Simple formulas typically begin with the equal sign (=), followed by numerical constants and calculation operators such as the plus (+), minus (-), asterisk (*), or forward slash (/). As an example, consider the following formula. When you combine multiple operations and functions into a single formula, Excel follows a predetermined order of operations.
