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.

Answer:

The field will not fit

Step-by-step explanation:

To find the angle, we will use cosine rule;

c² = (a² + b² - 2abcosC)

C in this case is θ

Thus;

15² = (8² + 20² - 2(8 × 20)cos θ)

225 = (64 + 400 - 320cos θ)

464 - 225 = 320cos θ

cos θ = 239/320

θ = cos^(-1) 0.7469

θ = 41.68°

Thus angle is not less than 40° as recommended. Thus, the field will not fit.

We reject the null hypothesis since the p-value is less than the significance level of 0.05.

The null hypothesis in statistics is a claim that presupposes there is no statistically significant distinction among the two or even more variables be compared. The antithesis of the alternative hypothesis, it is frequently denoted as H0 (Ha). While conducting statistical studies, the null is often evaluated to see if there is sufficient proof against it or not. The default assumption is typically the null hypothesis, and it serves as a benchmark for comparison of the statistical analysis's findings. A statistically significant distinction between the variables under comparison is said to exist if the statistical analysis yields sufficient data to refute a null hypothesis.

given

To test the hypothesis, we can utilise a z-test. This is the test statistic:

\(z = (x - E) / σ\)

where x is the observed percentage of patients whose conditions are getting better. x = 820 * 0.52 = 426.4 is the result. Therefore:

z = (426.4 - 393.6) / 0.026 = 1245.98

P(Z > z) = 1 - P(Z z) is the p-value for this one-tailed test, where Z is a normal standard variable. By using a typical table or calculator, we discover:

P(Z > 1245.98) < 0.0001

We reject the null hypothesis since the p-value is less than the significance level of 0.05.

We have enough data to draw the conclusion that the percentage of patients whose conditions are improving is more than 0.48.

From the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have inequality:

10p - 8 >12

10p > 12 + 8

10p > 20

p > 2

p ∈ (2, ∞)

The triangle for which angle a =30\degree, angle b=45\degree, and a=20, side a ≈ 20, side b ≈ 28.284, and side c ≈ 38.636

Two angles (a and b) and one side (a) are provided for us to solve the triangle. Let's call the side across from angle a side A, the side across from angle b side B, and the side across from the final angle (angle c) side C.

Here, it is given that,

angle a = 30 degrees

angle b = 45 degrees

side a = 20

angle c = 180 - (angle a + angle b)

angle c = 180 - (30 + 45)

angle c = 180 - 75

angle c = 105 degrees

We know that, a/sin(A) = b/sin(B) = c/sin(C)

a/sin(A) = b/sin(B) = c/sin(C)

20/sin(30) = b/sin(45) = c/sin(105)

b/sin(45) = 20/sin(30)

b = (sin(45) * 20) / sin(30)

b ≈ (0.7071 * 20) / 0.5

b ≈ 14.142 / 0.5

b ≈ 28.284

Now,

c/sin(105) = 20/sin(30)

c = (sin(105) * 20) / sin(30)

c ≈ (0.9659 * 20) / 0.5

c ≈ 19.318 / 0.5

c ≈ 38.636

Thus, side a ≈ 20, side b ≈ 28.284, and side c ≈ 38.636.

x-1.77=13.73

x=15.50

Step-by-step explanation:

First, we susbitute variable x for the amount earned. Next as she spent 1.77 and has 13.73 remaining we derive x-1.77=13.73. Finally, add 1.77 to both sides to get x=15.5.

Answer:

The equation is x - 1.77 = 13.73.

The simplified version is x = 15.50.

Step-by-step explanation:

The equation is x - 1.77 = 13.73.

The simplified version is x = 15.50.

To get to this answer, we first need to plug the provided numbers into a simple equation.

We can assume that "x" (the unknown number) is the total. The total minus the amount of money spent, $1.77, will equal the new total, $13.73.

Therefore, x - 1.77 = 13.73.

Next, we need to solve the problem. By adding 1.77 to both sides of the equal sign, we effectively isolate the variable.

-1.77 + 1.77 = 0; 13.73 + 1.77 = 15.50.

We can, at last, come to the conclusion that x = 15.50.

The woman will withdraw $300 given 6%   interest rate annually.

We can use the formula for simple interest to solve this problem:

I = Prt

where I is the interest earned, P is the principal (initial deposit), r is the annual interest rate as a decimal, and t is the time in years. Since the interest rate is given as an annual rate, we need to convert it to a daily rate by dividing by 365:

r = 0.06/365 = 0.00016438356

The time in years is 120/365 = 0.3287671233 years. Now we can plug in the values and solve for I:

I = 300 * 0.00016438356 * 0.3287671233 = 0.01699999999

The interest earned is $0.017, which is negligible. Therefore, the woman will withdraw the entire principal plus any interest earned, which is:

300 + 0.017 = $300.02

The function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

Transformation techniques

Transformation is the process of changing the position of an object on the xy-plane.

Given the parent function

f(x) = 4x

If the function is not reflected over x-axis, the resulting function will be f(x) = -4x

If the resulting function is compressed by a factors of 1/8, hence the final function rule will be;

g(x) = 1/8(-4x)

g(x) = -1/2x

Hence the function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

The first option is correct. Option A is correct.

LCL = 0.270, and UCL = 0.397

80% Confidence interval = (0.270, 0.397)

Step-by-step explanation:

The data for Y and N for the 90 companies is attached to this solution provided.

Y represents companies with at least 1 bilingual operator and N represents companies with no bilingual operator.

The number of Y in the data = 30

Hence, sample proportion of companies with at least one bilingual operator = (30/90) = 0.3333

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample proportion) ± (Margin of error)

Sample proportion = 0.3333

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error)

Critical value at 80% confidence level for sample size of 90 is obtained from the z-tables.

Critical value = 1.280

Standard error of the mean = σₓ = √[p(1-p)/n]

p = sample proportion

n = sample size = 90

σₓ = √[0.3333×0.6667)/90] = 0.0496891568 = 0.04969

80% Confidence Interval = (Sample proportion) ± [(Critical value) × (standard Error)]

CI = 0.3333 ± (1.28 × 0.04969)

CI = 0.3333 ± 0.0636021207

80% CI = (0.2696978793, 0.3969021207)

80% Confidence interval = (0.270, 0.397)

Answer:

a. The expression that represents the number of cups of hot chocolate drunk per day as a function of degrees Celsius is

y = -30x + 3600 pr the equivalent y = 3600 - 30x

b. How many cups would they drink at 5 degrees Celsius?

x = 5 --> y = 3600 - 30 X 5 --> y = 3600 - 150 --> y = 3450

c. How many cups would they drink at 25 degrees Celsius?

x = 25 --> y = 3600 - 30 X 25 --> y = 3600 - 750 --> y = 2850

d. Write an equation to determine the temperature if 3000 cups of hot chocolate were consumed in a day.

y = 3000 --> 3000 = 3600 - 30x

e. Solve the equation to find the temperature if 3000 cups of hot chocolate were consumed in a day.

--> 3000 = 3600 - 30x --> 3000 - 3000 + 30x = 3600 - 30x - 3000 + 30x --> 30x + 600 --> 30x/30 = 600/30 --> x = 20

f. Is this answer reasonable? Explain.

It is very reasonable.

At 0 degree C. they drink 3600 cups.

As the temperature increases, hot chocolate consumption decreases.

At 5 degree C. they drink less hot chocolate: 3450 cups.

Since 20 degree C. is even warmer, they should drink even less at 20 degree C., but not as little as the 2850 cups they drink on those very warm 25 degree C. days.

Step-by-step explanation:

We need to name/define variables:

y = number of cups of hot chocolate consumed in a day in Fairbanks.

x = temperature in degrees Celsius

"For each rise of 1 degrees Celsius, their consumption decreases by 30 cups per day."

That tells you that y is a linear function of x, so we should be able to write it as

y=mx + b with some constants for slope, m, and y-intercept, b.

It also tells you that the slope is m=-30.

"People living in Fairbanks drink 3600 cups of hot chocolate per day when the temperature is 0 degrees Celsius."

That gives you the value of y when x=0, which is the y-intercept,

b=3600
