The probability of getting 3 is P(A) = 1/216. The probability that sum being 3 is 1 / 216.

When three dice are thrown simultaneously, the probability that the sum is 3 is 1/216. A dice can show a minimum of one and a maximum of six dots, for a total of six sides, giving it a total of 6 * 6 * 6 = 216 possible outcomes.

:When three dice are thrown simultaneously, the probability that the sum is 3 is 1/216. The probability can be calculated as follows:

Let A be the event that the sum is 3. The number of ways to get 3 is 1, i.e., (1, 1, 1). The total number of possible outcomes is 6³,

since each die can have 6 possible outcomes.

Therefore, the probability of getting 3 is P(A) = 1/216.

To calculate the probability of demand exceeding the reorder point when the reorder quantity is set at 143 units, we need to follow these steps:Calculate the mean of demand during lead time (µd)Calculate the standard deviation of demand during lead time (σd) Calculate the reorder point (R)R = µd + z * σd (where z is the standard normal deviation corresponding to the service level)Calculate the safety stock (S)S = R - d, where d is the demand rate Calculate the order quantity (Q)Q = R + S - I (where I is the inventory in hand)

Calculate the probability of demand exceeding the reorder point. Probability (P) = 1 - P (Z ≤ ((R - µd) / σd))The mean of demand during lead time (µd) can be calculated as the product of the average daily demand (D) and lead time (L).

µd = D * L = 26 * 8 = 208 units.

The standard deviation of demand during lead time (σd) can be calculated using the formula below

:σd = √(D * L * σ^2) = √(26 * 8 * 12^2) = 99.91 units

.The reorder point (R) can be calculated using the formula below:R = µd + z * σd, where z is the standard normal deviation corresponding to the service level. Since the service level is not given in the problem, we assume a service level of 90%. The corresponding z-value for a 90% service level is

1.28.R = 208 + 1.28 * 99.91 = 338 units.

The safety stock (S) can be calculated using the formula below:S = R - d, where d is the demand rate. In this case, the demand rate is given as 26 units per day.

S = 338 - 26 = 312 units.

The order quantity (Q) can be calculated using the formula below:Q = R + S - I, where I is the inventory in hand. In this case, the inventory in hand is not given, so we assume it to be zero

.Q = 338 + 312 - 0 = 650 units.

To calculate the probability of demand exceeding the reorder point, we need to standardize the random variable Z using the formula below:Z = (X - µd) / σd, where X is the random variable. In this case,

X = R = 338.Z = (338 - 208) / 99.91 = 1.303.

The probability of Z being less than or equal to 1.303 can be found using the standard normal table. The value from the table is 0.9015.Therefore, the probability of demand exceeding the reorder point when the reorder quantity is set at 143 units is:

P = 1 - P (Z ≤ ((R - µd) / σd))P = 1 - 0.9015 = 0.0985

For example if its (4,-2) you go 4 up because it's positive and 2 down because its negative. After, you connect those two coordinates and get your FINAL answer after.

To solve this problem, we need to find the intersection of the circle with a 61-mile radius centered at the transmitter and the straight line connecting the two cities.

First, let's draw a diagram of the situation:

r

Copy code

T (transmitter)

|\

| \

|  \

|   \

|    \

|     \

|      \

|       \

C1      C2

Here, T represents the transmitter, C1 represents the city 68 miles north of the transmitter, and C2 represents the city 81 miles east of the transmitter. We want to find out how much of the straight line from C1 to C2 is within the range of the transmitter.

To solve this problem, we need to use the Pythagorean theorem to find the distance between the transmitter and the straight line connecting C1 and C2. Then we can compare this distance to the radius of the transmitter's range.

Let's call the distance between the transmitter and the straight line "d". We can find d using the formula for the distance between a point and a line:

scss

Copy code

d = |(y2-y1)x0 - (x2-x1)y0 + x2y1 - y2x1| / sqrt((y2-y1)^2 + (x2-x1)^2)

where (x1,y1) and (x2,y2) are the coordinates of C1 and C2, and (x0,y0) is the coordinate of the transmitter.

Plugging in the values, we get:

scss

Copy code

d = |(81-0)*(-68) - (0-61)*(-68) + 0*0 - 61*81| / sqrt((81-0)^2 + (0-61)^2)

 = 3324 / sqrt(6562)

 ≈ 41.09 miles

Therefore, the portion of the straight line from C1 to C2 that is within the range of the transmitter is the portion of the line that is within 61 miles of the transmitter, which is a circle centered at the transmitter with a radius of 61 miles. To find the length of this portion, we need to find the intersection points of the circle and the line and then calculate the distance between them.

To find the intersection points, we can solve the system of equations:

scss

Copy code

(x-0)^2 + (y-0)^2 = 61^2

y = (-61/68)x + 68

Substituting the second equation into the first equation, we get:

scss

Copy code

(x-0)^2 + (-61/68)x^2 + 68(-61/68)x + 68^2 = 61^2

Simplifying, we get:

scss

Copy code

(1 + (-61/68)^2)x^2 + (68*(-61/68))(x-0) + 68^2 - 61^2 = 0

Solving this quadratic equation, we get:

makefile

Copy code

x = 12.58 or -79.23

Substituting these values into the equation for the line, we get:

scss

Copy code

y = (-61/68)(12.58) + 68 ≈ 5.36

y = (-61/68)(-79.23) + 68 ≈ 148.17

Therefore, the intersection points are approximately (12.58, 5.36) and (-79.23, 148.17). The distance between these points is:

scss

Copy code

sqrt((12.58-(-79.23))^2 + (5.36-148.17)^2)

29565x(10^5)

Step-by-step explanation:

heartbeat in 1 day=10^5.

we have 365 days in a year. it means that;

365x(10^5)=365x(10^5). this is heartbeat for 1 year.

then for 81 years,we multiply the value of 1 year heartbeat by 81.

=29565x(10^5).

Chris's research costs can be calculated using the percentage increase in his return and the desired hourly wage. The cost of his research will be $375.45. As a result of the research, Chris's return will increase by $257.96. On a strict economic basis, Chris should perform the proposed research as the increase in return outweighs the cost.

To calculate the cost of Chris's research, we need to determine the amount of time he devotes to it. Let's assume he spends x hours on research. The cost of his research can be calculated by multiplying his desired hourly wage ($31.00) by the number of hours spent:

Cost of research = $31.00 × x

Now, to find x, we need to consider the percentage increase in Chris's return. The percentage increase is given as a range from 6.1% to 8.7%. Let's take the average of these percentages, which is (6.1% + 8.7%) / 2 = 7.4%. This means Chris's return will increase by 7.4% as a result of the research.

To find x, we can set up the following equation:

1.074 × initial return = final return

Simplifying the equation, we have:

initial return = final return / 1.074

Since the initial return is given as a percentage, we can express it as 100% (or 1 in decimal form). The final return can be expressed as 100% + 7.4% = 107.4% (or 1.074 in decimal form).

So, the equation becomes:

1 = 1.074 / initial return

Solving for initial return, we find:

initial return = 1.074

Now, we can substitute the initial return into the equation for cost of research:

Cost of research = $31.00 × x = $31.00 × (initial return - 1) = $31.00 × (1.074 - 1) = $31.00 × 0.074 = $2.294

Rounding this to the nearest cent, the cost of Chris's research is approximately $2.29.

Next, to find the increase in Chris's return as a result of the research, we can calculate:

Increase in return = final return - initial return = 1.074 - 1 = 0.074

Finally, we can calculate the increase in dollars:

Increase in dollars = Increase in return × initial return = $31.00 × 0.074 ≈ $2.30

Rounding this to the nearest cent, Chris's return will increase by approximately $2.30.

On a strict economic basis, Chris should perform the proposed research. The cost of research is $2.29, while the increase in return is $2.30. Therefore, the increase in return outweighs the cost, resulting in a positive net benefit.

The Hedging Table for the grain merchant including the basis, the net gain or loss in the spot and futures markets, and the net hedged selling price is attached.

To prepare the Hedging Table for the grain merchant, we need to calculate the basis, net gain or loss in the spot and futures markets, and the net hedged selling price for each transaction date.

Transaction Date: 15th October

- Purchase of 10,000 bushels of wheat at $12.50 per bushel.

- Sale of a 15th January wheat futures contract at $12.90 per bushel.

Basis = Spot Price - Futures Price

Basis = $12.50 - $12.90

Basis = -$0.40

Net Gain/Loss in Spot Market = (Spot Selling Price - Spot Purchase Price) * Quantity

Net Gain/Loss in Spot Market = ($12.40 - $12.50) * 10,000

Net Gain/Loss in Spot Market = -$1,000

Net Gain/Loss in Futures Market = (Futures Purchase Price - Futures Selling Price) * Quantity

Net Gain/Loss in Futures Market = ($12.90 - $12.50) * 10,000

Net Gain/Loss in Futures Market = $4,000

Net Hedged Selling Price = Spot Selling Price + Basis

Net Hedged Selling Price = $12.40 + (-$0.40)

Net Hedged Selling Price = $12.00

Transaction Date: 15th December

- Sale of 10,000 bushels of wheat in the physical market at $12.40 per bushel.

- Purchase of a 15th January futures contract at $12.50 per bushel.

Basis = Spot Price - Futures Price

Basis = $12.40 - $12.50

Basis = -$0.10

Net Gain/Loss in Spot Market = (Spot Selling Price - Spot Purchase Price) * Quantity

Net Gain/Loss in Spot Market = ($12.40 - $12.50) * 10,000

Net Gain/Loss in Spot Market = -$1,000

Net Gain/Loss in Futures Market = (Futures Purchase Price - Futures Selling Price) * Quantity

Net Gain/Loss in Futures Market = ($12.50 - $12.50) * 10,000

Net Gain/Loss in Futures Market = $0

Net Hedged Selling Price = Spot Selling Price + Basis

Net Hedged Selling Price = $12.40 + (-$0.10)

Net Hedged Selling Price = $12.30
