Step-by-step explanation:

A beverage company has decided to manufacture a new juice with mixed flavors, which is prepared from orange and pineapple. The vitamin contents are 5% of vitamin A and 2% of vitamin C in the orange flavor, while pineapple flavor contains 8% of vitamin C.

The company's policies are to add at least 20 L of orange flavor to the new juice and limit the vitamin C content to no more than 5%. The cost of orange flavor is $1000 per liter, while the cost of pineapple flavor is $400 per liter.To satisfy a minimum demand of 100 L of juice, we must determine the optimal amount of each flavor to use.A) A linear programming model is needed for the company to solve this problem (Minimize production cost of the new juice)B) Use a graphic solution for this problem.The objective function of the optimization problem can be given as:min C = 1000x + 400yThe constraints that the company has are,20x + 0y ≥ 100x + y ≤ 5x ≥ 0 and y ≥ 0The feasible region can be identified by graphing the inequality constraints on a graph paper. Using a graphical method, we can find the feasible region, and by finding the intersection points, we can determine the optimal solution.The graph is shown below; The optimal solution is achieved by 20L of orange flavor and 80L of pineapple flavor, as indicated by the intersection point of the lines. The optimal cost of producing 100 L of juice would be; C = 1000(20) + 400(80) = $36,000.C) If the company decides that the juice should have a vitamin C content of no more than 7%, it would alter the problem's constraints. The new constraint would be:x + y ≤ 7Dividing the equation by 100, we obtain;x/100 + y/100 ≤ 0.07The objective function and the additional constraint are combined to create a new linear programming model, which is solved graphically as follows: The feasible region changes as a result of the addition of the new constraint, and the optimal solution is now achieved by 20L of orange flavor and 60L of pineapple flavor. The optimal cost of producing 100 L of juice is $28,000.

In conclusion, the optimal amount of each flavor that should be used to satisfy a minimum demand of 100 L of juice is 20L of orange flavor and 80L of pineapple flavor with a cost of $36,000. If the company decides that the juice should have a vitamin C content of no more than 7%, the optimal amount of each flavor is 20L of orange flavor and 60L of pineapple flavor, with a cost of $28,000.

Options B, C, and D (Expected Utility, Maximin, and Minimax Regret) are decision-making criteria used in different contexts, but they are not specifically related to calculating ROI.

The calculation that should be used when calculating Return on Investment (ROI) is option A: Expected Monetary Value.

ROI is a financial metric that measures the profitability of an investment by comparing the gain or loss from the investment relative to its cost. It is typically expressed as a percentage.

To calculate ROI, the expected monetary value of the investment is considered. It takes into account the potential gains or losses associated with the investment and the probabilities of those outcomes. By multiplying the potential outcomes by their respective probabilities and summing them up, the expected monetary value can be calculated.

The number of wrapped present with 20 centimeters of tape is given as 5 presents.

In this question, we have the following values

12 centimeters of tape was used to wrap 3 presents

hence we would have

12 = 3 presents - - - - 1

Then we are to know the presents that would be wrapped with the use of 20 centimeters of tape.

we would have

20 = ? presents - - - 2

We have to bring the equations together

12 = 3 presents

20 = ? presents

? is the presents that is to be wrapped with 20 centimeters of tape. It is our unknown.

We would have to cross multiply

12 x ? = 3 x 20

Answer:

x = 16

Step-by-step explanation:

If the lines were parallel then (12x - 50) and (8x + 14) are alternate angles and are congruent , then

12x - 50 = 8x + 14 ( subtract 8x from both sides )

4x - 50 = 14 ( add 50 to both sides )

4x = 64 ( divide both sides by 4 )

x = 16

For a and b to be parallel then x = 16

Answer:

inverse: \(f^{-1}(x) = \sqrt[5]{x^3 - 5}\)

                                            explanation:

Given: f(x) = \((x^5 +5)^{\frac{1}{3} }\)

let f(x) be y

y =  \((x^5 +5)^{\frac{1}{3} }\)

To find inverse, make x the subject.

\(y^3 = x^5 + 5\)

\(y^3 - 5 = x^5\)

\(x = \sqrt[5]{y^3 - 5}\)

change signs:

\(f^{-1}(x) = \sqrt[5]{x^3 - 5}\)

The proportion of the population that is less than 39 is 72.57%. The probability that a randomly chosen value will be greater than 36 is approximately 12.10%.

7) First, we have to find the proportion of the population with a value less than 39 in a normal distribution with a mean of 33 and a standard deviation of 10.

Calculate the z-score for the value 39.
z = (X - mean) / standard deviation
z = (39 - 33) / 10
z = 6 / 10
z = 0.6

Look up the z-score (0.6) in a standard normal distribution table or use a calculator to find the proportion.
The proportion for a z-score of 0.6 is approximately 0.7257.

So, approximately 72.57% of the population is less than 39.

8) Now, we have to find the probability that a randomly chosen value will be greater than 36 in a normal distribution with a mean of 29 and a standard deviation of 6.

Calculate the z-score for the value 36.
z = (X - mean) / standard deviation
z = (36 - 29) / 6
z = 7 / 6
z ≈ 1.17

Look up the z-score (1.17) in a standard normal distribution table or use a calculator to find the proportion.
The proportion for a z-score of 1.17 is approximately 0.8790.

Since we want the probability that a randomly chosen value will be greater than 36, we need to find the proportion of values above the z-score of 1.17.
Probability = 1 - proportion
Probability = 1 - 0.8790
Probability ≈ 0.1210

Answer:

The correct answer is

b) Below 0

The correct option is (d) To the left of 0.

If the graph for a linear regression crosses the y-axis in negative values, the y-intercept of the regression line would be located to the left of 0 on the y-axis.

Therefore, the correct option is (d) To the left of 0. How to find the y-intercept of the regression line?

The y-intercept of a regression line is the value where the regression line intersects with the y-axis. It is the point where x = 0. In order to find the y-intercept of the regression line, we can use the equation of the regression line, which is y = mx + b. Here, m is the slope of the line and b is the y-intercept.

Therefore, if the regression line crosses the y-axis in negative values, it means that the y-intercept (b) is negative, and the line intersects the y-axis to the left of 0.

The bowl must hold at least 36 teaspoons to prepare the ingredients for 12 cupcakes.

To answer this question, we first need to determine how many teaspoons of each ingredient are required for 12 cupcakes. If the recipe calls for 1 teaspoon of baking powder, 1 teaspoon of salt, and 1 teaspoon of baking soda for each cupcake, then for 12 cupcakes, we would need 12 teaspoons of each ingredient.

So the bowl must hold at least 12 + 12 + 12 = 36 teaspoons in total.

It's always a good idea to have a little extra room in the bowl, so it's probably better to use a bowl that can hold a little more than 36 teaspoons. This will allow for room to mix the ingredients without them spilling over.

In conclusion, the bowl must hold at least 36 teaspoons to prepare the ingredients for 12 cupcakes.

Answer: y > -4

Step-by-step explanation: i believe this is your answer because i think you are asking for the range more or less. when you do this, you have to just ask yourself what points would be acceptable (any y point above -4) so the answer would be any y value more than -4, y > -4

The inequality for all the points of y above 4 is y > -4.

An inequality is comparison between two non-equal quantitates.

Inequalities are of four types.Less than,less than or equal to,greater than and greater than or equal to.If a is greater than be it is written as a>b.

For a is greater than or equal o b it is written as a ≥ b and for the other two types in equality will switch it's direction.

According to the given question we have to describe an inequality that describes all the points on the co-ordinate plane above y = -4.
