Answer: The graph of y > mx, where m > 0, consists of a dashed line and a shaded half plane. The line has a positive slope and passes through the origin. The shaded half plane is above the line.

Step-by-step explanation:

The stationary probability distribution is:

\(\pi = ((a^2)/(a^2 + B^2 + aB), (aB)/(a^2 + B^2 + aB), (B^2)/(a^2 + B^2 + aB))\)

To find the stationary probability distribution of the continuous-time Markov chain with jump rates q(i, i+1) = B for i=0,1 and q(i,i-1) = a for i=1,2, we need to solve the balance equations:

π(0)q(0,1) = π(1)q(1,0)

π(1)(q(1,0) + q(1,2)) = π(0)q(0,1) + π(2)q(2,1)

π(2)q(2,1) = π(1)q(1,2)

Substituting the given jump rates, we have:

π(0)B = π(1)a

π(1)(a+B) = π(0)B + π(2)a

π(2)a = π(1)B

We can solve for the stationary probabilities by expressing π(1) and π(2) in terms of π(0) using the first and third equations, and substituting into the second equation:

π(1) = π(0)(B/a)

π(2) = π(0)(\((B/a)^2)\)

Substituting these expressions into the second equation, we obtain:

π(0)(a+B) = π(0)B(B/a) + π(0)((\(B/a)^2)a\)

Simplifying, we get:

π(0) = \((a^2)/(a^2 + B^2 + aB)\)

Using the expressions for π(1) and π(2), we obtain:

π = (π(0), π(0)(B/a), π(0)(\((B/a)^2))\)

\(= ((a^2)/(a^2 + B^2 + aB), (aB)/(a^2 + B^2 + aB), (B^2)/(a^2 + B^2 + aB))\)

Answer:

The better buy is 16 cards for $12.20 because

Step-by-step explanation:

You need to find the individual price for each card in the packet. So first lets do 16 cards for $12.20, you divide $12.20 by 16 to get the price of one card. 12.2/16=0.7625, or about $0.76. Next we do $10.90 divided by 14, 10.9/14=0.7785, or about $0.78, which means 16 cards for $12.20 is the better buy!

The appropriate decision for this problem would depend on the calculated test statistic and its comparison to the critical value from the t-distribution table with a significance level of 0.01.

To determine the appropriate decision for this problem, the researcher needs to perform a hypothesis test. The null hypothesis (H0) would state that there is no difference in the mean prices of midrange homes between the two cities, while the alternative hypothesis (Ha) would state that there is a difference.

Since the sample sizes are relatively large (21 and 26), and the data is assumed to be normally distributed with similar variances, a two-sample t-test would be appropriate for comparing the means. The researcher can calculate the test statistic by using the formula:

\(t = (x1 - x2) / \sqrt{((s1^2 / n1) + (s2^2 / n2))}\)

Where x1 and x2 are the sample means, s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes.

With the calculated test statistic, the researcher can compare it to the critical value from the t-distribution table with (n1 + n2 - 2) degrees of freedom, and a significance level of 0.01. If the test statistic falls within the critical region (i.e., it exceeds the critical value), the researcher can reject the null hypothesis and conclude that there is a significant difference in mean prices between the two cities. Otherwise, if the test statistic does not exceed the critical value, the researcher fails to reject the null hypothesis and concludes that there is not enough evidence to suggest a difference in mean prices.

In this case, the appropriate decision would depend on the calculated test statistic and its comparison to the critical value.

It takes approximately 1.2 minutes to move the cans to the storage area when both conveyor belts are used.

We can begin the problem by using the formula:

work = rate x time

Let's denote the rate of the first belt as R1 and the rate of the second belt as R2. Then, we can write:

R1 = 200 pounds / 2 minutes = 100 pounds per minute

R2 = 200 pounds / 3 minutes ≈ 66.67 pounds per minute

When both belts are used, they work together to move the same 200 pounds of cans. Therefore, we can add their rates to get the total rate:

R = R1 + R2 = 100 + 66.67 = 166.67 pounds per minute

To find the time it takes to move the cans to the storage area, we can rearrange the formula:

time = work / rate

The total work is 200 pounds, so we have:

time = 200 pounds / 166.67 pounds per minute ≈ 1.2 minutes

Rotate the curve y = \(x^{3/27\), 0 ≤ x ≤ 3, about the x-axis.

To find the surface area of the solid generated by rotating the curve y = \(x^3\)/27, 0 ≤ x ≤ 3, about the x-axis, we can use the formula:

A = 2π∫\(a^b\) f(x) √(1 + [f'(x)\(]^2\)) dx

where f(x) is the function defining the curve, and a and b are the limits of integration.

In this case, we have:

f(x) =\(x^{3/27\)

f'(x) = \(x^{2/9\)

So, the formula becomes:

A = 2π∫0^3 (\(x^{3/27\)) √(1 +\([x^{2/9}]^2\)) dx

We can simplify the integrand by noting that:

1 + [\(x^2\)/9\(]^2\) = 1 + \(x^{4/81\) = (\(x^4\) + 81)/81

So, the formula becomes:

A = 2π/81 ∫\(0^3 x^3\) √(\(x^4\) + 81) dx

This integral is not easy to evaluate by hand, so we can use numerical methods or a computer algebra system to obtain an approximate value.

Using a numerical integration tool, we find that:

A ≈ 23.392 square units

Therefore, the surface area of the solid generated by rotating the curve y = x^3/27, 0 ≤ x ≤ 3, about the x-axis is approximately 23.392 square units.

Rotate the curve y = 4 - \(x^2\), 0 ≤ x ≤ 2, about the x-axis.

To find the surface area of the solid generated by rotating the curve y = 4 - x^2, 0 ≤ x ≤ 2, about the x-axis, we can again use the formula:

A = 2π∫\(a^b\) f(x) √(1 + [f'(x)]\(^2\)) dx

In this case, we have:

f(x) = 4 - \(x^2\)

f'(x) = -2x

So, the formula becomes:

A = 2π∫\(0^2\) (4 - \(x^2\)) √(1 + [-2x\(]^2\)) dx

Simplifying the integrand, we get:

A = 2π∫0^2 (4 - x^2) √(1 + 4x^2) dx

This integral is also not easy to evaluate by hand, so we can use numerical methods or a computer algebra system to obtain an approximate value.

Using a numerical integration tool, we find that:

A ≈ 60.346 square units

Therefore, the surface area of the solid generated by rotating the curve y = 4 - \(x^2\), 0 ≤ x ≤ 2, about the x-axis is approximately 60.346 square units.

Rotate the curve y = sqrt(x), 1 ≤ x ≤ 4, about the x-axis.

To find the surface area of the solid generated by rotating the curve y = sqrt(x), 1 ≤ x ≤ 4, about the x-axis, we can again use the formula:

A = 2π∫\(a^b\) f(x) √(1 + [f'(x)\(]^2\)) dx

There are 1820 different groups of applicants for 4 management trainee positions, 126 different groups of trainees consisting entirely of women, and a 0.0692 probability that the trainee class will consist entirely of women.

The number of different groups of applicants that can be selected for the four management trainee positions can be calculated using the combination formula:

nCr = n! / (r! * (n-r)!)

where n is the total number of applicants (16 in this case) and r is the number of positions to be filled (4 in this case).

So the number of different groups of applicants that can be selected is:

16C4 = 1820

Therefore, there are 1820 different groups of applicants that can be selected for the four management trainee positions.

The number of different groups of trainees that would consist entirely of women can be calculated using the combination formula again, but this time we are selecting all 4 positions from the 9 female applicants:

9C4 = 126

Therefore, there are 126 different groups of trainees that would consist entirely of women.

Assuming that all groups of four are equally likely to be selected, the probability that the trainee class will consist entirely of women can be calculated by dividing the number of different groups of trainees that consist entirely of women (126) by the total number of different groups of applicants (1820):

Probability = 126 / 1820 = 0.0692

So the probability that the trainee class will consist entirely of women is 0.0692 (rounded to four decimal places).

The survival time of a 60kg deer without food at -20 degrees Celsius depends on various factors, including its age, sex, and physical condition. However, assuming the deer is healthy and has 5kg of fat, it could potentially survive for around 30 to 50 days without food.

The exact survival time can vary depending on several factors, such as the deer's level of physical activity, environmental conditions, and how much energy it is expending to stay warm in the cold temperature. Additionally, if the deer is able to find sources of water, this can also increase its chances of survival.

It's important to note that this is just an estimate and that the actual survival time may vary. If the deer is injured or sick, its chances of survival may be reduced, and it may not be able to survive as long without food.

There are 18 deluxe rooms in the hotel.

To find the number of deluxe rooms in the hotel, we need to calculate the percentage of rooms that are deluxe.

The percentage of single-bed rooms is 55%, and the percentage of double-bedrooms is 30%. Therefore, the percentage of deluxe rooms can be calculated as:

Percentage of deluxe rooms = 100% - (Percentage of single-bed rooms + Percentage of double-bedrooms)

= 100% - (55% + 30%)

= 100% - 85%

= 15%

So, 15% of the total rooms in the hotel are deluxe rooms.

To determine the number of deluxe rooms, we can multiply the total number of rooms by the percentage of deluxe rooms:

Number of deluxe rooms = 15% of 120 rooms

= (15/100) * 120

To find the length of the guy wire for a radio transmission tower, trigonometry concepts are applied. Given a tower height of 160 feet, with the wire attached 13 feet from the top and making an angle of 29° with the ground, we can solve for the length of the guy wire, represented by x.

Using the Pythagorean theorem and considering the right triangle formed by the tower height, the wire attachment point, and the ground, we can set up the equation:

x = √((160 - 13)² + x²)

Next, we apply the tangent function to the given angle:

tan(29°) = (160 - 13) / x

Simplifying, we have:

0.5446 = 147 / x

To solve for x, we rearrange the equation:

x = 147 / 0.5446 ≈ 270.2 ft

Rounding to the nearest tenth of a foot, the length of the guy wire required is approximately 270.2 feet. This wire is attached 13 feet from the top of the tower and makes a 29° angle with the ground.
