The price elasticity of the supply is 0.43.

The relationship between the percentage change in a product's quantity demanded and the percentage change in price is known as price elasticity of demand. It helps economists comprehend how supply and demand shift in response to changes in a product's price.

Price Elasticity of Demand =\(\frac{Percentage Change in Quantity}{Percentage Change in Price }\)=\(\frac{\Delta Q}{\Delta P}\)

Further, the equation for price elasticity of demand can be elaborated into

Percentage change in quantity=ΔQ=\(\frac{(q_{2}-q_{1})}{(q_{2}+q_{1})}}\)

Percentage change in quantity=ΔP=\(\frac{(p_{2}-p_{1})}{(p_{2}+p_{1})}}\)

Where, \(q_{1}\)= Initial quantity, \(q_{2}\)= Final quantity,\(p_{1}\)= Initial price and \(p_{2}\) = Final price

Here,  \(q_{1}\)=10000,\(q_{2}\)=5000

Percentage change in quantity=ΔQ

=\(\frac{10000-5000}{10000+5000}\)

=\(\frac{5000}{15000}\)

=0.333

Here,  \(p_{1}\)=20 and \(p_{2}\)=15

Percentage change in quantity=ΔP

= \(\frac{20-15}{20+15}\)

=\(\frac{5}{35}\)

=0.143

Price Elasticity of Demand

=\(\frac{Percentage Change in Quantity}{Percentage Change in Price }\)

=\(\frac{0.333}{0.143}\)

Answer:

C

Step-by-step explanation:

you have the angle, adjacent and you want to find the hypotenuse

therefore use CAH - (I drew the triangle on the bottom of the attachment )

length of A / cos(angle) = hypotenuse

7 / cos(39)=9.007

Answer:

C: 9 to the nearest tenth

Step-by-step explanation:

You  have three choices on your calculator to solve this problem. Only 1 of the three will work.

Sin(39)

Tan(39)

Cos(39)

You want the hypotenuse (x) and you are given the adjacent side. The adjacent side is the other side that makes up the reference angle other than the hypotenuse.

Cos(theta) = adjacent side / hypotenuse.    The is the function you use.

Adjacent side = 7

Cos(39) = 7 / x               Multiply both sides by x

x * Cos(39) = 7               Divide by Cos(39)

x = 7 / Cos(39)

x = 9                               Isn't that neat? It is actually 9.0073. but C is the answer.

The optimal solution for the given linear programming model is:

max z = 38

when x1 = 5, x2 = 10, x3 = 0

To solve the given linear programming model using the simplex algorithm, we start by converting the inequalities into equations and introducing slack variables. The initial tableau is constructed with the coefficients of the decision variables and the right-hand side constants.

Next, we apply the simplex algorithm to iteratively improve the solution. By performing pivot operations, we move towards the optimal solution. In each iteration, we select the pivot column based on the most negative coefficient in the objective row and the pivot row based on the minimum ratio test.

After several iterations, we reach the optimal tableau, where all the coefficients in the objective row are non-negative. The optimal solution is obtained by reading the values of the decision variables from the tableau.

In this case, the optimal solution is z = 38 when x1 = 5, x2 = 10, and x3 = 0. This means that to maximize the objective function, the decision variables x1 and x2 should be set to 5 and 10 respectively, while x3 is set to 0.

To help account for variability, the pollster used a simple random sample.

Sampling is the selection of a subset (a statistical sample) of people from within a statistical population in statistics, assurance, and survey procedures. the population's characteristics that were sampled. Obtaining samples that are typical of the population being researched is the objective of statisticians.

In situations where it is not practical to evaluate the complete population, sampling offers insights and is more cost-effective and time-efficient than doing so.

Each observation gives a number for one or more characteristics of certain things or people, including their size, location, color, or weight.

In survey sampling, especially in stratified sampling, ratings can be added to the results to take into consideration the sample design. The practice is guided by conclusions from statistical theory and probability theory.

Answer:

i is always positive

Step-by-step explanation:

if be multiply 3 by 3 and get 9, then you multiply -2i by 2i and get -4i squared

9-4i^2 is now easy to solve unless we do now know the value of i, but since i is squared, i is always positive

Answer:

13

Step-by-step explanation:

Assuming this is (3-2i)(3+2i)

Use the FOIL method

First:       3(3) = 9

Outter:   3(2i) = 6i

Inner:     -2i(3) = -6i

Last:        -2i(2i) = -4i²

Add all of them together:

=   9 - 4i²   =    9  - 4(-1)   =   9 + 4  =  13

*NOTE that i² = -1

We have proved that Angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

To prove that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, we can use the following steps:

Step 1: Join points A and C with a line segment. Let's label the point where AC intersects with line segment BD as point E.

Step 2: Since line segment AC is drawn, we can consider triangle ABC and triangle ADC separately.

Step 3: In triangle ABC, we have angle B + angle ABC + angle BCA = 180 degrees (due to the sum of angles in a triangle).

Step 4: In triangle ADC, we have angle D + angle ADC + angle CDA = 180 degrees.

Step 5: From steps 3 and 4, we can deduce that angle B + angle ABC + angle BCA + angle D + angle ADC + angle CDA = 360 degrees (by adding the equations from steps 3 and 4).

Step 6: Consider quadrilateral ABED. The sum of angles in a quadrilateral is 360 degrees.

Step 7: In quadrilateral ABED, we have angle BAD + angle ABC + angle BCD + angle CDA = 360 degrees.

Step 8: Comparing steps 5 and 7, we can conclude that angle B + angle BCD + angle D = angle BAD + angle ABC + angle ADC.

Step 9: Rearranging step 8, we get angle BCD = angle BAD + angle ABC + angle ADC.

Therefore, we have proved that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

The correct answer is B.

The given statement does not provide any information about the items i and ii, so it is impossible to determine the comparison of their rates of change.

However, in general, the rate of change of an item can be compared to another item by calculating their respective derivatives with respect to time. If the derivative of item i is greater than the derivative of item ii, then the rate of change of item i is greater.

If the derivative of item ii is greater than the derivative of item i, then the rate of change of item ii is greater. If the derivatives are equal, then the rate of change of both items is equal. Without specific information about items i and ii, it is impossible to make a comparison.

Step-by-step explanation:

1. The probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5. 2. For Option a), Option c), Option d) the event not happening. Probabilities must fall between 0 and 1, inclusive, and cannot be negative or greater than 1.

1. The probability of obtaining an even number when rolling a fair die can be determined by dividing the number of favorable outcomes (even numbers) by the total number of possible outcomes (all numbers on the die). In the case of a standard six-sided die, there are three even numbers (2, 4, and 6) out of a total of six possible outcomes (1, 2, 3, 4, 5, and 6). Therefore, the probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5.

2. In terms of the numbers provided, the one that cannot be a probability is c) 1.001. Probabilities always range between 0 and 1, inclusive. A probability of 1 means that an event is certain to occur, while a probability of 0 means that an event will not occur. Any value greater than 1, such as 1.001, is not a valid probability because it implies that the event is more certain than certain. It is important to note that probabilities cannot exceed 1 or be negative.

In probability theory, a probability is a measure of the likelihood of an event occurring. It is always expressed as a value between 0 and 1, inclusive. A probability of 0 means that the event is impossible and will not occur, while a probability of 1 indicates that the event is certain to occur. Intermediate values between 0 and 1 represent different levels of likelihood.

Option a) −0.00001 cannot be a probability because probabilities cannot be negative. Negative values imply the presence of an event's complement (the event not happening) rather than the event itself.

Option b) 0.5 is a valid probability, representing an equal chance of an event occurring or not occurring. It indicates that there is a 50% chance of the event happening.

Option d) 0 is also a valid probability, indicating that the event is impossible and will not happen.

Option e) 1 is a valid probability, denoting that the event is certain to occur. The probability of an event occurring is 100%.

Option f) 20% is a valid probability, but it can also be expressed as the decimal fraction 0.2. It represents a 20% chance or a 1 in 5 likelihood of the event happening.

In conclusion, probabilities must fall between 0 and 1, inclusive, and cannot be negative or greater than 1.

The following function with A is linear and that of B is non linear.

Function A is given by,

5x-3y=0

Hence Function A is linear.

The plot of function B is not a straight line.

Hence Function B is not linear.

A mathematical equation must take the form y=mx+b in order to be classified as a linear function (in which m is the slope and b is the y-intercept). This form cannot be satisfied by a nonlinear function.

Only first degree variables and terms that contain the products of variables are present in a linear equation. However, in the case of nonlinear equations, either the equation comprises a product of variables or at least one of the variables is not of the first degree.

If a straight line forms the graph of an equation, it is linear. When x has a highest power of 1, this will take place. If the equation results in a straight line on a graph, it is a linear equation.

Otherwise, if you get a circle, parabola, or any other conic shape, the equation is quadratic or nonlinear.

A linear equation is one in which the highest power of x is one; otherwise, a nonlinear equation is one in which the highest power of x is greater than one.
