The expression -2x³ + 13x² + 3x + 50 is equivalent to 10 - (2x³ + 11x² - 2x - 35) + (x + 5) + 6(4x²

An algebraic expression is an expression which consists of variables, coefficients, constants, and mathematical operators such as addition, subtraction, multiplication and division. Generally, if two things are the same, then it is called equivalent. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. But if the values are plugged in the expression, both the expressions give the same result.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

In the given expression;

10 - (2x³ + 11x² - 2x - 35) + (x + 5) + 6(4x²); this can be reduced or simplified to -2x³ + 13x² + 3x + 50

2730 sets of officers are possible if there are members and any member can be elected to each position.

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:

p = 15! / (15 - 3)!

To avoid any perfect multicollinearity we need to  exclude any one of the binary class variables for all the entities which are independent of whether an given intercept is present across the given equation or not.

Fixed outcomes is a statistical regression version wherein the intercept of the regression version is authorized to differ freely throughout people or groups. It is frequently implemented to panel information with the intention to manage for any individual-unique attributes that don't range throughout time. Use fixed-outcomes (FE) each time you're most effective inquisitive about reading the effect of variables that fluctuate over time.

Answer:

No solution.

Step-by-step explanation:

1. Move terms to the left side

x² - 3x = -8

x² - 3x - (-8) = 0

2. Use the quadratic formula

x = [tex]\frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex]

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

x² - 3x + 8 = 0

a = 1

b = -3

c = 8

x = [tex]\frac{-(-3) + \sqrt{(-3)^2 - 4 * 1 * 8} }{2*1}[/tex]

3. Simplify

After simplifying:

Planetary distance is the measure of distance between two planets which vary based on the placement of the planet in an orbit. An orbit is the path where planets revolve around the Sun in the solar system. The planets’ orbits form an elliptical shape. To measure the distance between two planets in the solar system an astronomical measure used is astronomical unit (AU). An Astronomical Unit (AU) is the average distance between Earth and the Sun and is used to measure distances within our solar system. The distance between Mars from Earth is equivalent to 0.52 AU while the distance between Jupiter and Saturn is 4.32 AU.

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)

Assuming QF is the full employment equilibrium then in the Figure, if the level of spending is equal to AD1, the AD shortfall would be greater than XZ. The answer is B.

The respective figure as referred in the question is as attached.

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.

Using the Dominant strategy and Nash equilibrium, helps you to choose a number between large sample (0-100) such that the choosing number is 2/3 of average guess of all and become a winner.

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.

2nd order thinkers guess/3 primary thinkers

= (2 / 3) × 33 = 22.

3rd order - 3rd order thinkers guess 2/3 of 1st order thinkers = (2 / 3) × 22 = 15.

The weight that is left when 18759 grams of bricks are removed is 3.241 kg

From the question, we have the following parameters that can be used in our computation:

Pile of bricks = 22 kg

The weight removed from the pile = 18759 grams

The remaining weight can be calculated using the following subtraction equation

Remaining weight = Pile of bricks - The weight removed from the pile

Substitute the known values in the above equation, so, we have the following representation

Remaining weight = 22 kg - 18759 grams

Convert grams to kg

This gives

Remaining weight = 22 kg - 18.759 kg

Evaluate the difference in the above equation

Remaining weight = 3.241 kg
