Option A, For the aptitude puzzle, the number of ways each of people has the same number of internet friends is 60.

We want to count the number of ways that the 6 people can be internet friends with each other given that each person has the same number of internet friends and no one has an internet friend outside of the group.

Let k be the number of internet friends each person has. Since each person knows 5 other people in the group, we have 6k = 5 * 6, which means that k=5.

Thus, each person has 5 internet friends. We can choose these 5 friends in 5 to choose 5 times 4 choose 5 times 3 choose 5 times 2 choose 5 times 1 choose 5 = 1 × 0 × 0 × 0 × 0 = 0 ways since we can't choose 5 friends from fewer than 5 people.

Therefore, the answer is (A) 60.

The answer is

The combined present worth of the costs associated with the proposed bridge design, including construction and annual operating costs, is $10,583,333.

To calculate the combined present worth of costs, we need to consider the construction cost and the annual operating cost over the infinite life of the bridge. We will use the concept of present worth, which is the equivalent value of future costs in today's dollars.

The present worth of the construction cost is simply the initial cost itself, which is $9,000,000. This cost is already in present value terms.

For the annual operating cost, we need to calculate the present worth of perpetuity. A perpetuity is a series of equal payments that continue indefinitely. In this case, the annual operating cost of $700,000 represents an equal payment.

To calculate the present worth of the perpetuity, we can use the formula PW = A / MARR,

where PW is the present worth, A is the annual payment, and MARR is the minimum attractive rate of return (also known as the discount rate). Here, the MARR is given as 12%.

Plugging in the values, we have PW = $700,000 / 0.12 = $5,833,333.

Adding the present worth of the construction cost and the present worth of the perpetuity, we get $9,000,000 + $5,833,333 = $14,833,333.

However, since we are looking for the combined present worth, we need to subtract the salvage value, which is zero in this case. Therefore, the combined present worth of the costs associated with the proposed bridge design is $14,833,333 - $4,250,000 = $10,583,333, rounded to the nearest dollar.

The numerical values of the Nash equilibrium prices for Firm X and Firm Y are PX = 64 and PY = 8, respectively

In a duopoly market with two firms, X and Y, the demand functions and marginal cost for each firm are given. To find the "best responses" for each firm, we need to determine the optimal price for each firm in terms of the rival's price. Subsequently, we can find the Nash equilibrium prices, where both firms play their best responses simultaneously.

For Firm X:

ProfitX = (90 - 3PX + 2PY - 10) * PX

Taking the derivative with respect to PX and setting it equal to zero:

d(ProfitX) / dPX = 90 - 6PX + 2PY - 10 = 0

Simplifying the equation:

6PX = 80 - 2PY

PX = (80 - 2PY) / 6

For Firm Y:

ProfitY = (90 - 3PY + 2PX - 10) * PY

Taking the derivative with respect to PY and setting it equal to zero:

d(ProfitY) / dPY = 90 - 6PY + 2PX - 10 = 0

Simplifying the equation:

6PY = 2PX - 80

PY = (2PX - 80) / 6

These equations represent the best responses for each firm in terms of the rival's price.

To find the numerical values of the Nash equilibrium prices, we need to solve these equations simultaneously. Substituting the expression for PY in terms of PX into the equation for PX, we get:

PX = (80 - 2[(2PX - 80) / 6]) / 6

Simplifying the equation:

PX = (80 - (4PX - 160) / 6) / 6

Multiplying through by 6:

6PX = 480 - 4PX + 160

10PX = 640

PX = 64

Substituting this value of PX into the equation for PY, we get:

PY = (2 * 64 - 80) / 6

PY = 8

Therefore, the numerical values of the Nash equilibrium prices for Firm X and Firm Y are PX = 64 and PY = 8, respectively.

Slope-intercept form: y = 0.5x - 0.5

Step-by-step explanation:

Answer:

it is 1 2/10 but simplified to 1 1/5

Step-by-step explanation:

The mechanic that would charge less for a 50-hour repair is Mechanic A.

Mathematically, the point-slope form of any straight line can be modeled by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

For the table for Mechanic B, an equation which represent its data points is given by:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 300 = (600 - 300)/(20 - 10)(x - 10)

y - 300 = 300/10(x - 10)

y = 30x - 300 + 300

y = 30x.

When x = 50 hours, the charges for Mechanic A is given by:

y = 25x + 100

y = 25(50) + 100

y = $1,350

When x = 50 hours, the charges for Mechanic B is given by:

y = 30x

y = 30(50)

y = $1,500

In conclusion, we can logically deduce that Mechanic B charges a higher fee than Mechanic A.

\(angle(?)=tan^{-1} (1.42857)=55^{0}\)

Hope this helps

Answer:

55 degrees (e)

Step-by-step explanation:

This is a trigonometry problem. We are given a right triangle with an unknown angle in which the opposite and adjacent sides of the angle are known (10 and 7). We also know that the tangent of any angle is the length of the opposite divided by the length of the adjacent. If we let the unknown angle be Ф, we can say that tan(Ф) = 10/7. To isolate Ф, all we have to do is take the inverse. In other words, Ф = arctan(10/7). Using a graphing calculator, we find that arctan(10/7) is approximately 55 degrees.

The exponential growth or decay of a certain phenomenon, such as population growth or decay, over time. The graph typically looks like an “S” or exponential curve, with an initial slow start then an increasing or decreasing rate of change.

20An example of an exponential graph is one that shows the exponential growth or decay of a certain phenomenon, such as population growth or decay, over time. The graph typically looks like an “S” or exponential curve, with an initial slow start followed by an increasing or decreasing rate of change. This rate of change is often characterized by a mathematical function, such as an exponential function, which can be used to calculate the expected change in the phenomenon over a given period of time. For example, an exponential graph can be used to show how a population will grow or decline over time, based on its current population size, growth rate, and other factors. Exponential graphs can also be used to show the growth or decay of a chemical reaction, the rate of change of a financial asset, or any other phenomenon that can be characterized by an exponential function.

The approximate distribution (give distribution name and parameters) of the total length will be =  450 minutes

The estimated distribution of the total length of Tina's simulation study is a triangular distribution with a base worth of 2 minutes, a greatest worth of 4 minutes, and a mode (most reasonable worth) of (2+4)/2 = 3 minutes.

Since the simulation time is generally consistently distributed somewhere in the range of 2 and 4 minutes, the total simulation time will be the sum of 150 free random variables each with a triangular distribution.

Hence, the total simulation time will also have a triangular distribution with a base worth of 2 minutes x 150 = 300 minutes, a greatest worth of 4 minutes x 150 = 600 minutes, and a method of (300+600)/2 = 450 minutes.

The expression for the total number of cans of food would be: 9s

A variable is a symbol or letter that denotes a possible range of values or quantities. It is used to express relationships between numbers and to solve equations and problems, and is typically represented by a letter like x, y, or z.

A variable's value can be determined by its context of use or by resolving an inequality or equation that it appears in. Variables are frequently used in algebra to represent unknowns or to simplify challenging formulas.

Let's use the variable "s" to represent the number of students participating in the food drive.

Then, the expression for total number of cans of food would be: 9s

This is because each student is committing to bringing 9 cans of food, so if there are "s" students participating, then the total number of cans of food would be 9 times the number of students (9s).

Answer: g+d=46

Step-by-step explanation:

We want to write and solve a system of equations to model the given situation.

g = 2*d - 8

g + d = 46

The first thing we need to do, is define the variables we will be using.

g = number of songs that the guitarist wrote.

d = number of songs that the drummer wrote.

From "The guitarist wrote 8 fewer than twice the number of the songs that the drummer wrote."

We can write:

g = 2*d - 8

And we know that in total they wrote 46 songs, so we can also write:

g + d = 46

The domain of the function is 1 ≤ x < 2.

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates).

We have f : \(\frac{1}{\sqrt{x-1} } + \frac{1}{\sqrt{2-x} }\)

\(\sqrt{x-1}\) ≥ 0

x- 1 ≥ 0

x ≥ 1

Similarly , \(\sqrt{2-x}\) > 0
