A plaintiff who sues on the basis of disparate-treatment discrimination in hiring must make out a prima facie case of illegal discrimination and will win in the absence of a legally acceptable employer defense. True

Disparate treatment discrimination refers to the form of discrimination from an employer who blatantly treats an employee, or a potential employee differently based on the individual’s race, religion, color, sex, national origin, etc. It is intentional employment discrimination. A plaintiff who sues on the basis of disparate-treatment discrimination in hiring must make out a prima facie case. Prima facie case refers to a cause of action or defense that is sufficiently established by a party's evidence to justify a verdict in their favor, provided such evidence is not rebutted by the other party. The facts of the case are assumed to be true unless contradicted by evidence, hence if the plaintiff has produced sufficient evidence of their claim that the case will be decided for the plaintiff unless the defendant produces evidence to rebut it. To establish prima facie case, the plaintiff must be a member of the a protected class, must have applied and was qualified for the job in question, was rejected by the employer, and employer continued to seek applicants for the position or filled the position with a person not in a protected class. If plaintiff establishes all of this, burden now falls on employer as they must then prove their reasoning.

The value of cost of all the product is 32.50

The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of competing companies in the market.

Formulas and Calculations for Sale Prices Percent Off Price Formula

List price - (List price x (percentage / 100)) = Discounted price

For instance, the sale price is 25% off the list price of $130.

Divide 25% by 100 to get the decimal equivalent: 25/100 = 0.25

Divide the list price by the decimal percent: 130*0.25 = 32.50

Subtract the amount of the discount from the list price: 130 - 32.50 = 97.50

Using the formula:

130 - (130*(25/100)) =

\s130 - (130*0.25) =

       \s130 - 32.50 = 97.50

25% off $130 is $97.50

Formula for Fractional Off Price

List price - Discounted price (List price x fraction)

Example: The sale price is one-third of the list price of $120.

Divide the list price by the fractional discount: 120*1/3 = 40

Subtract the amount of the discount from the list price: 120 - 40 = 80

Using the formula:

120 - (120*1/3) = \s120 - 40 = 80

1/3 off $120 is $80

The surface area of the solid pyramids are as follows;

First figure; 436 square units

Second figure; 319 square units

Third figure; 673 square units

A pyramid is a shape that consists of a polygon base and side faces that are triangular.

First figure

The figure is a pentagonal pyramid of height 8 units and side length of 10 units

The apothem, a, can be obtained from the formula;

[tex]a = \dfrac{s}{2\cdot tan \left(\dfrac{180}{n} \right)}[/tex]

s = 10

n = 5

[tex]a = \dfrac{10}{2\cdot tan \left(\dfrac{180}{5} \right)} \approx 6.88[/tex]

Slant height ≈ √(8² + 6.88²) ≈ 10.55

Area of the 5 triangles = 5 × (1/2) × 10 × 10.55 ≈ 263.75

Area of pentagonal base ≈ (1/2) × 6.88 × 5 × 10 = 172
Area of the figure ≈ 263.75 + 172 ≈ 436

Second figure;

Square pyramid

n = 4

When s = 8, we get;

[tex]a = \dfrac{12}{2\cdot tan \left(\dfrac{180}{4} \right)} =6[/tex]

Slant height of the 8 units long side = √(6² + 10²) ≈ 11.66

Area of two of the four triangle surfaces = 2×(1/2)×8 ×11.66≈ 93.28

When s = 12 we get;

[tex]a = \dfrac{8}{2\cdot tan \left(\dfrac{180}{4} \right)} =4[/tex]

Slant height of the 12 units long side = √(4² + 10²) ≈ 10.77

Area of two of the four triangle surfaces = 2×(1/2)×12 × 10.77 ≈ 129.24

Area of the rectangular base = 12 × 8 = 96

Area of the figure = 93.28 + 129.24 + 96 ≈ 319

Third figure

Octagonal pyramid

n = 8

s = 8

[tex]a = \dfrac{8}{2\cdot tan \left(\dfrac{180}{8} \right)}\approx 9.66[/tex]

Slant height = √(9.66² + 6²) ≈ 11.37

Area of the 8 triangles = 8 × (1/2) × 8 × 11.37 ≈ 363.84

Area of the octagonal base = 2×(1 + √2)×s²

Therefore;

2×(1 + √2)×8² ≈ 309.02

The given statement that Adverse selection occurs because of asymmetric information is true . Because it happens when one party have no idea about other party .

Adverse Selection:

Adverse selection generally refers to the situation in which the seller has information that the buyer does not have or, conversely, knows about aspects of the product's quality. In other words, it is a case of misusing asymmetric information. Information asymmetry, also known as information impairment, occurs when one party to a transaction has more important knowledge than the other party.

For example, corporate managers may be more willing to issue stock if they know that the stock is overvalued relative to its true value. Buyers may suffer losses by purchasing overvalued stocks. In the used car market, sellers can learn about vehicle defects and charge buyers extra fees without disclosing the problem.

A common consequence of negative selection is that consumers lack information from sellers and manufacturers, increasing costs and creating market asymmetries.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

Then the equation is given as,

(x + 12) / (x + 5) = (x + 5) / x

Simplify the equation, then we have

(x + 12) / (x + 5) = (x + 5) / x

The two companies will charge the same for 20 tons of sugar and the cost when the two companies charge the same is calculated to be $9510

The amount of sugar for which the charge will be equal can be determined by using an algebraic expression as follows;

5495 + 200.75x = 7500 + 100.50x

Here x represents tons of sugar

200.75x - 100.50x = 7500 - 5495

100.25x = 2005

x = 2005 ÷ 100.25

x = 20

Hence for 20 tons of sugar, the two companies will charge the same. Now by substituting the value of x = 20, the cost when the two companies charge the same can be determined as follows;

5495 + 200.75x = 5495 + 200.75 (20) = 5495 + 4015 = $9510
