Answer:

8:30 A.M.

Step-by-step explanation:

Start by adding up the total time spent traveling.

3h 30min + 1h 30min + 1h 15 min = 5h 15 min

If she arrived in Orlando at 1:45 P.M., count back 5 h 15 min.

1:45 - 15 min = 1:30 - 5h = 8:30 A.M.

If the population size is 500, then the standard error of the sample mean is approximately 0.447.

The standard error of the sample mean is a measure of how much the sample mean differs from the true population mean on average. The formula for calculating the standard error of the sample mean is:

SE=σ/√n

where σ is the standard deviation of the population, n is the sample size.

Using the given values, we can calculate the standard error of the sample mean as follows:

σ = 10

n = 50

SE = σ/√n = 10/√50 = 1.41

When the population size is very large relative to the sample size (n), the standard error of the sample mean can be approximated as:

SE=σ/√N

where N is the population size.

Using the given values, we can calculate the approximate standard error of the sample mean as follows:

N = 500

σ = 10

SE = σ/√N = 10/√500 = 0.447

Thus, the standard error of the sample mean, when the population size is 500, is approximately 0.447.

No, every 2-approximation algorithm for finding a minimum vertex cover is not necessarily a 2-approximation algorithm for finding a maximum independent set.

The reason for this is that the two problems, minimum vertex cover and maximum independent set, are not symmetric in their definitions and objectives.

In the minimum vertex cover problem, the goal is to find the smallest possible set of vertices that covers all edges in the graph. On the other hand, in the maximum independent set problem, the objective is to find the largest possible set of vertices such that no two vertices in the set are adjacent.

An approximation algorithm for the minimum vertex cover problem guarantees that the size of the vertex cover found by the algorithm is at most twice the size of the optimal minimum vertex cover. This means that the algorithm provides a solution that is within a factor of 2 of the optimal solution.

However, this does not imply that the same algorithm will provide a solution within a factor of 2 of the optimal maximum independent set. The reason is that the concepts of vertex cover and independent set are complementary. A vertex cover is a set of vertices that covers all edges, whereas an independent set is a set of vertices with no adjacent vertices.

Therefore, while a 2-approximation algorithm for minimum vertex cover guarantees that the size of the vertex cover is at most twice the size of the optimal solution, it does not necessarily imply that the algorithm will find a maximum independent set with a size within a factor of 2 of the optimal solution.

To find out how much money you would save on car 1, you would multiply the sticker price by the discount percentage (expressed as a decimal). In this case, that would be $20,000.00 x 0.23 = $4,600.00. So you would save $4,600.00 on car 1.

To find out how much money you would save on car 2, you would multiply the sticker price by the discount percentage (expressed as a decimal). In this case, that would be $17,000.00 x 0.10 = $1,700.00. So you would save $1,700.00 on car 2.

Based on the calculations, Car 1 would be a better deal. Even though Car 2 is cheaper by $3,000.00 before discount, Car 1 saves more on discount of $4,600.00 compared to Car 2's $1,700.00. So Car 1 would be more affordable overall.

Exercise needs to be consistent and done at regular times. The body can adjust more effectively and swiftly when there is consistency. Exercise should ideally be performed 3-5 times per week.

Exercise is any physical activity done to increase one's physical or mental fitness.

Exercise and physical activity not only aid to enhance physical health but also help to promote mental health.

A healthy mind follows from a healthy body.

By lowering body weight, frequent physical activity lowers the risk of developing serious conditions like heart attack, cardiovascular disease, diabetes, and high blood pressure. Regular exercise revitalizes the body and the mind.

Additionally, it raises energy levels, mood, and sleep quality.

Hence, Exercise must be performed consistently and at regular intervals. When there is consistency, the body can adjust more quickly and efficiently. The ideal number of times to exercise per week is three to five.

Solution B has a 100 times greater {H} than Solution A.

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A higher pH indicates a lower hydrogen ion concentration, and a lower pH indicates a higher hydrogen ion concentration. Therefore, Solution B has a higher hydrogen ion concentration than Solution A. To calculate the ratio of {H} between the two solutions, we must take the inverse of the pH difference. In this case, the difference is 3. Therefore, the ratio of {H} between the two solutions is 1/3, or 100 times greater {H} in Solution B than in Solution A.

The cost of the wall paper per square feet is 0.72 dollars.

The wall paper is rectangular in shape. The dimension of the wall paper is 42 feet by 25.5 feet.

The total cost of the wall paper is 771.12 dollars. Therefore, let's find the cost per square ft.

Hence,

area of the wall paper = 42 × 25.5

area of the wall paper = 1071 ft²

Therefore,

1071 ft² =  771.12 dollars

1 ft² = ?

Hence,

cost per square feet = 771.12  / 1071

cost per square feet = 0.72 dollors

The expected product(s) resulting from addition of br2 to (e)-3-hexene is 1,2-dibromohexane.

What is hexene?

Hexene is a linear chain alkene with six carbon atoms and one double bond. Hexene is also known as hexylene. It is an unsaturated hydrocarbon, which means it contains a carbon-carbon double bond.What is Br2?Bromine (Br2) is a diatomic molecule consisting of two bromine atoms that are covalently bonded to form a reddish-brown liquid at room temperature and pressure.

Bromine is an oxidizing and a halogen element that is a member of Group 17 of the periodic table.

What is the product of Br2 addition to hexene?

The expected product(s) resulting from addition of br2 to (e)-3-hexene would be 1,2-dibromohexane. The addition of Br2 to an alkene is an electrophilic addition reaction in which Br2 adds across the double bond to produce vicinal dibromides.

In the case of (e)-3-hexene, the Br2 will add across the double bond in an anti-addition manner (i.e. adding on the opposite sides) to give 1,2-dibromohexane, as shown below:

Therefore, the answer is 1,2-dibromohexane.

Number of year remain = 18 - 5 = 13 year

Number of months = 13 x 12 = 156 months

Find:

Money need to save each month

Computation:

Money need to save each month = 90,000 / 156

Money need to save each month  = $576.92 each month

Answer:

\(xy=wz\)

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = \(y\) km/min

Time taken up the hill = \(x\) minutes

Speed of Wilmer down the hill = \(z\)  km/min

Time taken up the hill = \(w\) minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

\(Distance = Speed \times Time\)

Distance up the hill = \(y\times x =xy\ kilometers\)

Distance down the hill = \(z\times w =wz\ kilometers\)

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:
