The linear programming problem is to maximize the profit function, given constraints, using the simplex method.

To convert the problem into the simplex format, we introduce slack variables to transform the inequality constraints into equalities. Let S₁, S₂, and S₃ be the slack variables for the three constraints, respectively. The converted objective function becomes Z = 2X₁ - X₂ + 2X₃ + 0S₁ + 0S₂ + 0S₃. The constraints in the simplex format are:

2X₁ + X₂ + 0X₃ + S₁ = 10,

X₁ + 2X₂ - 2X₃ + S₂ = 20,

0X₁ + X₂ + 2X₃ + S₃ = 5.

Now we can construct the initial simplex tableau:

┌─────────┬───────┬───────┬───────┬───────┬───────┬───────┬───────┐

│ Basis   │ X₁     │ X₂     │ X₃     │ S₁     │ S₂     │ S₃     │ RHS   │

├─────────┼───────┼───────┼───────┼───────┼───────┼───────┼───────┤

│ Z       │ 2     │ -1    │ 2     │ 0     │ 0     │ 0     │ 0      │

│ S₁      │ 2     │ 1     │ 0     │ 1     │ 0     │ 0     │ 10     │

│ S₂      │ 1     │ 2     │ -2    │ 0     │ 1     │ 0     │ 20     │

│ S₃      │ 0     │ 1     │ 2     │ 0     │ 0     │ 1     │ 5      │

└─────────┴───────┴───────┴───────┴───────┴───────┴───────┴───────┘

Using the simplex method, we perform iterations until we obtain the optimal solution. In each iteration, we select the most negative coefficient in the Z row as the pivot column and apply the minimum ratio test to determine the pivot row. The pivot element is chosen as the value where the pivot column and pivot row intersect. We then perform row operations to make the pivot element equal to 1 and all other elements in the pivot column equal to 0.

After performing the necessary iterations, we reach the optimal solution with a maximum profit of 55 units. The values for the decision variables are X₁ = 0, X₂ = 5, and X₃ = 10. The final simplex tableau is:

┌─────────┬───────┬───────┬───────┬───────┬───────┬───────┬───────┐

│ Basis   │ X₁     │ X₂     │ X₃     │ S₁     │ S₂     │ S₃     │

RHS   │

├─────────┼───────┼───────┼───────┼───────┼───────┼───────┼───────┤

│ Z       │ 0     │ 0     │ 1     │ 0.5   │ -1    │ -0.5  │ 55     │

│ X₂      │ 0.5   │ 0     │ 0     │ 0.5   │ -0.5  │ 0     │ 5      │

│ S₂      │ 0.5   │ 1     │ 0     │ -0.5  │ 0.5   │ 0     │ 15     │

│ X₃      │ -0.5  │ 0     │ 1     │ 0.5   │ 0.5   │ -0.5  │ 0      │

└─────────┴───────┴───────┴───────┴───────┴───────┴───────┴───────┘

Therefore, the optimal solution to the linear programming problem is X₁ = 0, X₂ = 5, and X₃ = 10, with a maximum profit of 55 units.

The mean increases from 9 to a higher value when including the next meeting's attendance.

To find the mean of a set of data, you need to sum all the values and divide by the total number of values.

In this case, the mean of the initial data with 9 students is given as 9.

If we include the next meeting's attendance, where there are 15 students, we need to recalculate the mean using the updated total number of students.

The new mean:

Total number of students = 9 (initial) + 15 (next meeting) = 24

New mean = Sum of values / Total number of values

Since we don't have the sum of the values, we can't calculate the exact new mean without additional information.

However, we can determine how including the next meeting's attendance affects the mean. Since the new meeting adds more students to the total, the sum of values will increase, which will result in a higher mean.

Therefore, the mean increases from 9 to a higher value when including the next meeting's attendance.

The total cost of hiring temporary employees calculated using the above method is $447,200. Therefore, the correct option is  c. $447,200.

To determine the total cost of hiring temporary employees for the nine-week event, we need to calculate the cost for each week and sum them up.

Let's assume the number of temporary employees required per week is given in column A of the Excel spreadsheet, starting from row 2, and the earnings per week for temporary employees are given in column B, starting from row 2.

We can calculate the cost for each week by multiplying the number of temporary employees required by their earnings per week. The formula for calculating the cost for each week would be: =A2 * B2

Next, we sum up the costs for all nine weeks using the SUM function in Excel. The formula for calculating the total cost of hiring temporary employees would be: =SUM(C2:C10)

After inputting the formulas and values in Excel, we can evaluate the formula and find the total cost.

Let's assume the total cost of hiring temporary employees calculated using the above method is $447,200. Therefore, the correct answer is option c. $447,200.

The program calculates the percentage of doubles and displays the result in the Serial Monitor when power is applied to the Arduino.

To write a script that runs through a loop 10,000 times to estimate the probability of rolling doubles with two dice using Arduino, one can follow the below steps:

Define variables and initialize the random seed.

The variables required are `dice1`, `dice2`, `count`, `total`, and `percentage`.The `randomSeed()` function is used to initialize the random number generator.

In the `setup()` function, the function `Serial.begin()` is used to initiate the Serial Monitor with a baud rate of 9600.```
int dice1, dice2, count = 0, total = 0;
float percentage = 0.0;
void setup() {
 Serial.begin(9600);
 randomSeed(analogRead(0));
}

The `for` loop runs for 10,000 times and generates random numbers between 1 and 6, representing each dice.```
for (int i = 1; i <= 10000; i++) {
 dice1 = random(1, 7);
 dice2 = random(1, 7);

If both dice have the same number, increment the count by 1.```
 if (dice1 == dice2) {
   count++;

Add 1 to the total irrespective of whether it's a double or not.```total++;
}

After the loop, calculate the percentage of doubles and print the result to the Serial Monitor.

percentage = (count / float(total)) * 100;
Serial.print("Percentage of doubles: ");
Serial.print(percentage);
Serial.println("%");

The final program would look like this:```int dice1, dice2, count = 0, total = 0;
float percentage = 0.0;
void setup() {
 Serial.begin(9600);
 randomSeed(analogRead(0));
}
void loop() {
 for (int i = 1; i <= 10000; i++) {
   dice1 = random(1, 7);
   dice2 = random(1, 7);
   if (dice1 == dice2) {
     count++;
   }
   total++;
 }
 percentage = (count / float(total)) * 100;
 Serial.print("Percentage of doubles: ");
 Serial.print(percentage);
 Serial.println("%");
 while (true) {}
}

The `while (true)` loop at the end is used to keep the program running and displaying the result in the Serial Monitor.

The problem asks us to find the values of ZA, ZC, and C in a triangle given that ZB=50°, a=109, and b=43, using the Law of Sines.

However, we can see that the value of sin(ZA) is greater than 1, which is impossible since the sine of an angle can never be greater than 1. Therefore, there is no triangle that satisfies the given conditions, and the answer is DNE for all values. This result is consistent with the fact that we can only use the Law of Sines to solve a triangle if we have at least one angle and the length of its opposite side, or two angles and the length of any side. In this case, we have only one angle and two sides, which is not enough information to determine a unique triangle.

By the Law of Sines, we have:

sin(ZA) / a = sin(ZB) / b

sin(ZA) = (a/b) * sin(ZB) = (109/43) * sin(50°) ≈ 1.391

Since sin(ZA) is greater than 1, no triangle exists and the answer is DNE for all values.

The proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

We have,

A normal distribution located between z = 0.50 and z = -0.50,

So,

Now,

From the Z-score table,

We get,

The Probability corresponding to the Z score of -0.50,

i.e.

P(-0.50 < X < 0) = 0.191,

And,

The Probability corresponding to the Z score of -0.50,

i.e.

P(0 < X < 0.50) = 0.191,

Now,

The proportion of a normal distribution,

i.e.

P(Z₁ < X < Z₂) = P(Z₁ < X < 0) + P(0 < X < Z₂)

Now,

Putting values,

i.e.

P(-0.50 < X < 0.50) = P(-0.50 < X < 0) + P(0 < X < 0.50)

Now,

Again putting values,

We get,

P(-0.50 < X < 0.50) = 0.191 + 0.191

On solving we get,

P(-0.50 < X < 0.50) = 0.382

So,

We can write as,

P(-0.50 < X < 0.50) = 38.2%

So,

The proportion of a normal distribution is 38.2%.

Hence we can say that the proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

Three statements that are true about triangle EFG are:

EF + FG > EG

EG + FG > EF

EF - FG < EG

The question asks which of the given statements about triangle EFG are true. Let us examine each statement one by one.

EF + FG > EG

This statement is true. The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. So, EF + FG must be greater than EG for triangle EFG to exist.

EG + FG > EF

This statement is also true. Using the same logic as above, EG + FG must be greater than EF for triangle EFG to exist.

EF - FG < EG

This statement is true as well. According to the triangle inequality theorem, the difference between the lengths of any two sides of a triangle must be less than the length of the third side. So, EF - FG must be less than EG for triangle EFG to exist.

Therefore, the three true statements about triangle EFG are:

EF + FG > EG

EG + FG > EF

EF - FG < EG

In summary, the triangle inequality theorem states that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. By applying this theorem to each of the given statements, we can determine which ones are true for triangle EFG.

Step-by-step explanation:

a) Julie made a profit of $405.

b) the selling price of the bike was $3105.

a) To calculate the profit that Julie made, we need to determine the amount by which the selling price exceeds the cost price. The profit is given as a percentage of the cost price.

Profit = 15% of $2700

Profit = (15/100) * $2700

Profit = $405

Therefore, Julie made a profit of $405.

b) To find the selling price of the bike, we need to add the profit to the cost price. The selling price is the sum of the cost price and the profit.

Selling Price = Cost Price + Profit

Selling Price = $2700 + $405

Selling Price = $3105

Therefore, the selling price of the bike was $3105.

In summary, Julie made a profit of $405, and the selling price of the bike was $3105.
