The government agency as a monopolist will produce and sell internet connections up to the point where the marginal cost is 1/2. The price will be set at 1, given the perfectly elastic demand function.

In the scenario where a government agency has a monopoly in the provision of internet connections and the inverse demand function is given by p = 1, we can analyze the market equilibrium and the implications for pricing and quantity.

The inverse demand function, p = 1, implies that the market demand for internet connections is perfectly elastic, meaning consumers are willing to purchase any quantity of internet connections at a price of 1. As a monopolist, the government agency has control over the supply of internet connections and can set the price to maximize its profits.

To determine the optimal pricing and quantity, the monopolist needs to consider the marginal cost of providing internet connections. In this case, the marginal cost is given as 1/2. The monopolist will aim to maximize its profits by equating marginal cost with marginal revenue.

Since the inverse demand function is p = 1, the revenue received by the monopolist for each unit sold is also 1. Therefore, the marginal revenue is also 1. The monopolist will produce up to the point where marginal cost equals marginal revenue, which in this case is 1/2.

As a result, the monopolist will produce and sell internet connections up to the quantity where the marginal cost is 1/2. The monopolist will set the price at 1 since consumers are willing to pay that price.

Percentage of times that she goes to school by car = 41%

Step-by-step explanation

It is given that Shelia walks to school 35% of the time and rides the bus 24% of the time.

Given that she only has 3 alternative ways to get to school (walking, taking the bus or going to school by car), it means the remaining of the time, she rides a car.

(Percentage of times that she walks to school) + (Percentage of times that she takes the bus) + (Percentage of times that she goes to school by car) = 100%

35% + 24% + (Percentage of times that she goes to school by car) = 100%

59% + (Percentage of times that she goes to school by car) = 100%

Percentage of times that she goes to school by car = 100% - 59%

Percentage of times that she goes to school by car = 41%

Regression equation correctly models the data is: y = -43.98x + 1,279.93

To determine the regression equation that correctly models the data, we can use the method of linear regression. The regression equation for a straight line is generally expressed as y = mx + b, where m is the slope and b is the y-intercept.

Using the given table, we can calculate the necessary values to determine the regression equation. Let's denote the sigma notation as Σ.

The slope (m) can be calculated using the formula:

\(m = (Σxy - (Σx)(Σy) / n(Σx^2) - (Σx)^2)\)

Plugging in the values from the table:

m =\((776,600 - (299)(12,400) / 6(18,109) - (299)^2)\)

m = (776,600 - 3,708,800 / 6(18,109) - 89,401)

m = (-2,932,200 / 66,654)

m ≈ -43.98

The y-intercept (b) can be calculated using the formula:

b = (Σy - m(Σx)) / n

Plugging in the values from the table:

b = (12,400 - (-43.98)(299)) / 6

b ≈ 1,279.93

The correct regression equation that models the data is:

y = -43.98x + 1,279.93

Out of the given options, the correct regression equation is:

y = -43.98x + 1,279.93

The x-intercept of function f(x) is x = 7.

We have,

Since the x-intercept of a function is the value of x at which the function equals zero, we can find it by setting f(x) = 0 and solving for x.

Let's assume that the function f(x) is a linear function of form f(x) = mx + b, where m is the slope and b is the y-intercept.

Since we know that f(-1) = 7 and f(5) = 7/2, we can set up two equations:

-7m + b = 7 (when x = -1)

5m + b = 7/2 (when x = 5)

To solve for m and b, we can subtract the first equation from the second to eliminate b:

5m + b - (-7m + b) = 7/2 - 7

12m = -13/2

m = -13/24

Now we can substitute m into either equation to solve for b:

-7(-13/24) + b = 7

b = 91/24

Therefore,

The function f(x) is f(x) = (-13/24)x + 91/24.

To find the x-intercept, we can set f(x) = 0:

(-13/24)x + 91/24 = 0

x = 7

Thus,

The x-intercept of function f(x) is x = 7.

Step-by-step explanation:

total number of cards in a deck : 52

number of face card per suite : 3

total number of suites : 4 (hearts, clubs, diamonds, spades)

3 * 4 = total number of face cards

12/52 = 0.23 = probability of drawing a face card

remaining card are non face cards

52-12 = 40

40 non face cards

40/52 = 0.77 = probability of drawing a non face card

probability of drawing a face card followed by a non face card

multiply probabilities together to find combined probability

probability of drawing a face card * probability of drawing a non face card

The linear function for the given graph is y = x + 20.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function. It has one independent variable and one dependent variable. For slope (m) and y-intercept (b) form, the equation is given by:

y = mx + b

From the graph,

The coordinates of the given graph are (0,20) and (20,40)

Then, slope (m) = (40-20)/(20-0) = 20/20 = 1

and y-intercept (b) = 20

So, the equation will be y = 1x + 20

Hence, the linear function for the given graph is y = x + 20.

The new demand function given that D = 17,000 when x is $3 per unit is: D(x) = 1400 (√25-x²) + 12,800

The Demand Function A demand function is defined as p=f(x), p = f (x), where p is the unit price and x is the number of units of the commodity in question, and is often described as a decreasing function of x; that is, p=f(x), p = f (x) drops as x grows.

Given that D'(x)=-1400x/(√25-x²)

Integrate both sides
D(x) = 1400 √(25-x²) + C

If D(4) = 17,000

17,000 = 1400 * 3 + C

C = 12,800

The reasonable constraint so the function is at least 600 would be A. 0 ≤ x ≤ 20.

Given the function y = -2x² + 40x + 600, we want to find the constraint for x so that the function's value is at least 600.

Since the parabola opens downward (as a is negative), the function will be at least 600 for all values of x within the interval where the parabola is above y = 600. The vertex of the parabola is at its maximum value, so we should look for the interval around the vertex (10, 800).

Looking at the given constraints, the option "0 ≤ x ≤ 20" is a reasonable constraint that ensures the function is at least 600. The parabola starts at a value of 600 at x = 0, reaches its maximum value at the vertex, and then returns to a value of 600 at x = 20.

The equation of the line would be y = (4/5)x + 4 which in slope-intercept form represents the graph.

The graph is given in the question.

As per the given line, we take two points (0, 4) and (5, 8)

Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = 0, y₁ = 4

x₂ = 5, y₂ = 8

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Substitute values in the equation, we get

⇒ y - 4 = (8 - 4)/(5-0 )[x -0]

⇒ y - 4 = (4/5)x

⇒ y = (4/5)x + 4

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We have two events, A and B.

\(P(A \cup B) = P(A) + P(B) - P(A \cap B)\)

In which:

\(P(A \cup B)\) is the probability of at least one of these events happening.

P(A) is the probability of A happening.

P(B) is the probability of B happening.

\(P(A \cap B)\) is the probability of both happening.

In this question:

Event A: Passes the first course.

Event B: Passes the second course.

The probability she passes the first course is 0.7.

This means that \(P(A) = 0.7\)

The probability she passes the second course is 0.67.

This means that \(P(B) = 0.67\)

The probability she passes at least one of the courses is 0.79.

This means that \(P(A \cup B) = 0.79\)

What is the probability she passes both courses

\(P(A \cup B) = P(A) + P(B) - P(A \cap B)\)

\(0.79 = 0.70 + 0.67 - P(A \cap B)\)

\(P(A \cap B) = 0.58\)

0.58 = 58% probability she passes both courses
