If the function be f(x) = 4x - 2 then the value of f(3) exists 10.

An expression, rule, or law that establishes a connection between an independent variable and a dependent variable.

In mathematics, a variable is referred to as the alphabetic symbol used to represent a number or numerical value. An unknown quantity is represented by a variable in algebraic equations.

In mathematics, a function is a relationship where the values of one or more independent variables determine the values of a single dependent variable. The term "function" denotes that the independent variable influences the dependent variable.

Let the function be f(x) = 4x - 2

substitute the value of x = 3, then

f(3) = 4 × 3 - 2

simplifying the above equation, we get

f(3) = 10

Therefore, the value of f(3) exists 10.

Trigonometric Identity for

Cos2θ = Cos²θ-Sin²θ -(i)

Sin²θ+ Cos²θ=1 -(ii)

Then  Sin²θ=1-Cos²θ

Replacing  Sin²θ with 1-Cos²θ in equation (i)

Then

Cos2θ= Cos²θ -(1-Cos²θ )

Cos2θ= Cos²θ - 1 + Cos²θ

Cos2θ= 2Cos²θ - 1

Putting values

28/53= 2Cos²θ-1

28/53+1=2Cos²θ

28+53/53=2Cos²θ

81/52=2Cos²θ

81/53 X 1/2 =Cos²θ

81/106 =Cos²θ

Then Cosθ=[tex]\sqrt{\frac{81}{106} }[/tex]

Where,

 81 = 9X9 =9²

106 =   53X2

Cosθ= ±9/[tex]\sqrt{106}[/tex]

From the identity (ii)

Sin²θ + Cos²θ=1

Putting value

Sin²θ+ 81/106=1

Sin²θ = 1- 81/106

Sin²θ = 106 - 81/53

Sin²θ = 25/106

Full employment equilibrium refers to the equilibrium where all resources in the economy are fully utilized (employed). Full employment is a situation in which all available labor resources are being used in the most economically efficient way, so there is no cyclical or deficient-demand unemployment.

When the natural rate of unemployment is equal to the unemployment rate, this means the cyclical rate of unemployment is zero. So, when this relationship happens, the economy is considered to be at full employment.

The mean and standard deviation of the number of people with blood type a-positive in 100 randomly selected is μ=85, σ=3.5707

The standard deviation is a statistic that measures the amount of variation or dispersion of a group of values.

Standard deviation is usually abbreviated SD and is most commonly represented in mathematical texts and equations by the lower case Greek letter (sigma) for population standard deviation or the Latin letter s for sample standard deviation.

A low standard deviation indicates that the values are close to the mean of the set (also known as the expected value), whereas a high standard deviation indicates that the values are spread out over a broader range.

Given, The population proportion of success is p=0.85

And also given that the sample size is n=100

b) The population mean is:

μ=np

μ=100(0.85)

μ=85

Therefore, mean=85

And the population standard deviation is:

σ=√np(1-p)

σ=√100(0.85)(1-0.85)

σ=3.5707

The step-by-step method of mean deviation given below.

What is the mean deviation method?

When calculating the average departure from the mean value of a particular data set, statisticians employ a measure known as the mean deviation. Following the steps below will make it simple to determine the mean deviation of the data values.

In statistics, the term "deviation" refers to the discrepancy between the observed value of a data point and its expected value. As a result, mean deviation, also known as mean absolute deviation, is the typical departure of a data point from the mean, median, or mode of the data collection.

MAD = (∑ f1 |xi - x⁻|) / ∑ f1

fi is the frequency of repetition xi, xi of denotes the mid-value of the class interval.

Example,  Say your data set is: 9, 2, 5, 4, 12, 7, 8, 11, 9, 3, 7, 4, 12, 5, 4, 10, 9, 6, 9, 4.

The Mean is: 9 + 2 + 5 + 4 + 12 + 7 + 8 + 11 + 9 + 3 + 7 + 4 + 12 + 5 + 4 + 10+ 9 + 6 + 9 + 4. Over 20. That equals 104 over 20 = 7.

Statistics refers to deviation as the difference between the observed value of a data point and the expected value.

Permutations Without Repetition: Permutation repetitions select a set of items from a set of choices that can be distinguished, with each item only being selected once in each set. All collections with unique sets and unique orders of elements in a set are included in the total permutations.

The idea of permutations without replacement must be used because each member can only hold one office and each position holds a specific office.

The formula of permutation is,

p = n! / (n  - r)!

where r denotes the number of elements to be selected and n denotes the number of selections.

From a selection of 15 candidates, there are the following options for electing 3 members to fill a particular position:

Dominant Strategy:

A dominant strategy refers to a player's preference for a particular choice of action, independent of the actions and decisions of other players in a strategy game. A dominant strategy is based on the playoffs the player wins.

The concept of Nash Equilibrium is not too difficult to understand. Imagine any combination of player choices. For example, everyone picks 34 in the hope that it matches her 2/3rds of other people's guesses. Nash proved that every game has at least one such equilibrium if randomized strategies are allowed.

Zeroth order - If everyone was a zero-order thinker, just guess randomly between 0 and 100 and pick a random number. Average = ( 0 + 100 ) / 2 = 50.

1st order thinkers guess 2/3 of 0th order thinkers = (2 / 3) × 50 = 33.
