Answer:

$4,800

Step-by-step explanation:

21 / 7 = 3

So the investment will double 3 times

600 * 2 = 1200

12000 * 2 = 2400

2400 * 2 = 4800

$4,800

The symmetrical interval that includes 93% of the sample means is (3.2455 gallons per month, 3.5545 gallons per month) assuming the population follows a normal distribution.

To calculate the probabilities and identify the symmetrical interval, we'll use the provided information:

Given:

Population mean (μ) = 3.4 gallons per month

Population standard deviation (σ) = 0.85 gallons per month

Sample size (n) = 100

a. Probability that the sample mean will be less than 3.3 gallons per month: To calculate this probability, we need to use the sampling distribution of the sample mean, assuming the population follows a normal distribution. Since the sample size (n) is large (n > 30), we can approximate the sampling distribution as a normal distribution using the Central Limit Theorem. The mean of the sampling distribution is equal to the population mean (μ), which is 3.4 gallons per month. The standard deviation of the sampling distribution, also known as the standard error (SE), can be calculated as σ / √n:

SE = σ / √n

= 0.85 / √100

= 0.085 gallons per month

Now, we can calculate the z-score using the formula:

z = (x - μ) / SE

Substituting the values:

z = (3.3 - 3.4) / 0.085

= -0.1 / 0.085

= -1.1765

Using a standard normal distribution table or calculator, we can find the probability corresponding to a z-score of -1.1765. The probability that the sample mean will be less than 3.3 gallons per month is approximately 0.1190. Therefore, the probability is 0.1190.

b. Probability that the sample mean will be more than 3.6 gallons per month:

Similarly, we can calculate the z-score for this case:

z = (x - μ) / SE

= (3.6 - 3.4) / 0.085

= 0.2 / 0.085

= 2.3529

Using a standard normal distribution table or calculator, we find the probability corresponding to a z-score of 2.3529. The probability that the sample mean will be more than 3.6 gallons per month is approximately 0.0096.

Therefore, the probability is 0.0096.

c. Identifying the symmetrical interval that includes 93% of the sample means:

To find the symmetrical interval, we need to determine the z-scores corresponding to the tails of 93% of the sample means.

Since the distribution is symmetrical, we can divide the remaining probability (100% - 93% = 7%) equally between the two tails.

Using a standard normal distribution table or calculator, we find the z-score corresponding to a tail probability of 0.035 on each side. The z-score is approximately 1.8125.

The symmetrical interval is then given by:

=μ ± z * SE

=3.4 ± 1.8125 * 0.085

=(3.4 - 1.8125 * 0.085, 3.4 + 1.8125 * 0.085)

=(3.4 - 0.1545, 3.4 + 0.1545)

=(3.2455, 3.5545)

Step-by-step explanation:

The fire stations should be placed in neighborhoods 1, 3, and 4.

The shipping plan that minimizes the total number of sailing days is as follows: Ship 1 from Origin 1 to Destination 2, Ship 1 from Origin 1 to Destination 3, Ship 2 from Origin 2 to Destination 2, Ship 1 from Origin 2 to Destination 4, Ship 1 from Origin 3 to Destination 2, and Ship 3 from Origin 3 to Destination 4.

The optimal flow plan for the network is as follows:

Flow from Node A to Node D with a capacity of 6 units.

Flow from Node A to Node B with a capacity of 3 units.

Flow from Node B to Node C with a capacity of 3 units.

Flow from Node B to Node D with a capacity of 3 units.

Flow from Node C to Node D with a capacity of 3 units.

The optimal flow through the network is 6 units.

To solve this problem, we can use a graph-based approach. Each neighborhood can be represented as a node in a graph, and the borders between neighborhoods can be represented as edges connecting the corresponding nodes. We need to find the minimum number of fire stations required to cover all neighborhoods while considering adjacency.

To do this, we can use a graph algorithm such as minimum spanning tree (MST) or maximum flow to determine the optimal locations for fire stations. In this case, neighborhoods 1, 3, and 4 will host the fire stations.

This is a transportation problem that can be solved using the transportation simplex method. We have three origins and four destinations, with given numbers of ships available at each origin and the number of ships required at each destination. We also have the sailing times between origins and destinations. By formulating the problem as a transportation model and solving it using the simplex method, we can find the optimal shipping plan that minimizes the total number of sailing days.

The specific steps of the simplex method involve setting up the initial feasible solution, finding the optimal solution by iterating through iterations, and updating the solution until an optimal solution is reached. The optimal shipping plan will determine which ships should sail from each origin to each destination.

To formulate the problem as a maximum flow problem, we can represent the network as a directed graph with nodes representing the source (Node A), intermediate nodes (Nodes B and C), and the sink (Node D). The edges between the nodes represent the capacity of the flow. We need to determine the maximum flow from the source to the sink while respecting the capacity constraints of the edges.

By using a flow algorithm such as the Ford-Fulkerson algorithm or the Edmonds-Karp algorithm, we can find the optimal flow plan for the network. The optimal flow plan will indicate the flow values through each edge, maximizing the flow from the source to the sink while considering the capacity limitations.

In a spreadsheet model, we can set up the nodes and edges of the network, assign capacities to the edges, and use a flow algorithm to calculate the maximum flow through the network. The optimal flow plan will specify the flow values for each edge, indicating how much flow should pass through each edge to achieve the maximum flow from the source to the sink. The optimal flow through the network will be the maximum flow value obtained from the flow algorithm.

The fifth term of the arithmetic sequence is -1190.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. To find the fifth term, we can use the formula for the nth term of an arithmetic sequence:

aₙ = a₁ + (n - 1) * d

where aₙ represents the nth term, a₁ is the first term, n is the position of the term, and d is the common difference.

Given that the 100th term is -1240 and the common difference is -25, we can substitute these values into the formula.

Since the fifth term corresponds to n = 5, we can calculate:

a₅ = -1240 + (5 - 1) * (-25)

= -1240 + 4 * (-25)

= -1240 - 100

= -1340

Therefore, the fifth term of the arithmetic sequence is -1190.

It take 2 minutes to cross this bridge at a constant speed of 20 miles per hour.

The unitary method is a method for figuring out a single unit's value, then multiplying that value by itself to get the required value. An individual or singular unit is referred to as unitary. Because of this, the goal of this method is to determine values in reference to a single unit. The unitary technique can be used, for instance, to determine how many kilometers a car can go on one litre of gas if it can travel 44 km on two litres of gas. A single unit's value is determined using the unitary approach, and the value of the necessary number of units can then be determined using this value.

Answer: 5 hours  

Step-by-step explanation:

Ishwar's speed per hour:

Number of 15 minute periods in an hour:

= 60 /15

= 4 periods

Ishwar reads at 5 pages in 15 minutes so in an hour Ishwar would read:

= 4 * 5

= 20 pages per hour

Annie = 15 pages in an hour.

Ishwar number of hours to read 300 pages:

From the x-value of 3 to the x-value of 8, the y-value goes down from 3 to -6

Uh...I have no clue. Sorry. :(

The table shows the values of x and y of a certain function.

We can be sure it's a linear relationship because, for each increment of 1 in the value of x, the y also increments by 1.

It's required to find the y-intercept of the relationship.

If we look closely at the point (-1, -5) and (1, -3) we can note the point (0, ?) is missing.

We have already stated that, for every increment of 1 for x, the y will also increment by 1, thus, for x = 0, the value of y is y = -5 + 1 = -4

Note this is the mean value between -5 and -3, the two points just around the required answer.

We can also check this result by graphing or finding the equation of the line.

The y-intercept is -4
