Answer: We can use the formula for the price elasticity of demand to solve this problem:

Price elasticity of demand = percent change in quantity demanded / percent change in price

We are given that the price of chicken breast rises from $3.00 to $3.60 per pound, which is a 20% increase:

percent change in price = (3.60 - 3.00) / 3.00 = 0.20 = 20%

We are also given that the demand for chicken breast falls by 25%, which is a 25% decrease:

percent change in quantity demanded = -25%

Using these values in the formula, we get:

Price elasticity of demand = (-25%) / (20%) = -1.25

Since we are interested in the absolute value of the price elasticity of demand, we have:

|Price elasticity of demand| = |-1.25| = 1.25

A price elasticity of demand greater than 1 is considered elastic, and a price elasticity of demand less than 1 is considered inelastic. Therefore, the answer is (d) 1.25; elastic.

If Juan baked 250 cookies in 2 hours, then he can make approximately 2.08 cookies in one minute.

The unitary method involves finding the value of one unit and then using that to find the value of any number of units.

In this problem, the unit we are interested in is cookies per minute. We need to find out how many cookies Juan can make in one minute, given that he can make 250 cookies in 2 hours.

To find out how many cookies Juan can make in one hour, we can use the unitary method as follows:

1 hour = 60 minutes (since there are 60 minutes in one hour)

So, if Juan can make 250 cookies in 2 hours, he can make:

250 cookies / 2 hours = 125 cookies per hour

Using the unitary method again, we can find out number of cookies Juan can make in one minute:

1 hour = 60 minutes

So, Juan can make:

125 cookies / 60 minutes = 2.08 cookies per minute

Answer:

To solve the inequality |h + 3| < 5, we need to consider two cases, depending on whether the expression inside the absolute value bars is positive or negative:

Case 1: h + 3 >= 0

If h + 3 >= 0, then we can remove the absolute value bars without changing the inequality:

h + 3 < 5

Subtracting 3 from both sides, we get:

h < 2

So the solution for this case is h < 2.

Case 2: h + 3 < 0

If h + 3 < 0, then the inequality becomes:

-(h + 3) < 5

Multiplying both sides by -1 (and reversing the inequality), we get:

h + 3 > -5

Subtracting 3 from both sides, we get:

h > -8

So the solution for this case is h > -8.

Putting these two solutions together, we have:

-8 < h < 2

Therefore, the solution set in set-builder notation is:

{h | -8 < h < 2}

The x-intercept is the point where a line crosses the x-axis

Step-by-step explanation:

a. Probability of finding the ring is 0.2 or 20%.

b. Probability of not finding the ring is 0.8 or 80%.

c. Digging in the shaded square region at the right does not improve Kendrick's chances of finding the ring because the probability of finding the ring per unit area is the same in all the regions.

The probability of finding the ring in the 2-foot square shaded region can be calculated below as follows:

Probability = (area of shaded region) / (area of entire sandbox)

area of the shaded region = 2 * 2

area of the shaded region = 4

area of the entire sandbox = 5 * 4

area of the entire sandbox =  20

Probability = 4 / 20

Probability = 0.2 or 20%.

b. The probability of not finding the ring:

Probability of not finding the ring = 1 - Probability of finding the ring

Probability of not finding the ring = 1 - 0.2

Probability of not finding the ring = 0.8 or 80%.

c. Digging in the larger square region does not improve Kendrick's chances of finding the ring because the probability of finding the ring depends only on the ratio of the area of the shaded region to the area of the entire sandbox.

The geometric mean of two numbers is the square root of their product. Hence, the geometric mean 'a' of 2 and 1/4 is approximately equal to 0.70710678118.

Recall that the geometric mean of two numbers is the square root of their product. This means that we need to multiply the two numbers (2 and 1/4) and then take the square root of the result.

Multiply 2 and 1/4:

2 × 1/4 = 1/2

Take the square root of the result:

a = √(1/2)

Simplify the square root:

a = √(1/2) = √(1)/√(2) = 1/√(2)

Rationalize the denominator by multiplying the top and bottom by √(2):

a = (1/√(2)) × (√(2)/√(2)) = √(2)/2

Approximate the result to a desired level of accuracy, if necessary. In this case, rounding to 11 decimal places gives:

a ≈ 0.70710678118

Therefore, the geometric mean 'a' of 2 and 1/4 is approximately equal to 0.70710678118

Increasing the concentration of reactants typically increases the reaction rate

What is the rate of reaction?

The rate of the reaction indicates the speed with which the reaction is completed or product is formed.

Increasing the concentration of reactants typically increases the reaction rate because it increases the frequency of collisions between the reactant molecules.

In a chemical reaction, the reactant molecules must collide with each other with sufficient energy and proper orientation for the reaction to occur. If the concentration of reactants is low, there will be fewer reactant molecules present in a given volume, and therefore, fewer collisions will occur. As a result, the reaction rate will be slower.

On the other hand, if the concentration of reactants is high, there will be more reactant molecules present in a given volume, and therefore, more collisions will occur. This increased frequency of collisions leads to a higher probability that reactant molecules will have sufficient energy and proper orientation to react, and thus, the reaction rate will be faster.

It's important to note that increasing the concentration of reactants will only increase the reaction rate up to a certain point. Beyond a certain concentration, the reaction rate will not increase further, as the reactant molecules will already be colliding with each other at a high enough frequency to produce the maximum possible reaction rate.

Answer:

  A) Only for 180° rotations

Step-by-step explanation:

You want to know if a quadrilateral can be rotated so that each side is parallel to the corresponding side of its image.

In general, a line segment's image will be parallel to the original if it is rotated 180°. Hence the line segments that make up a quadrilateral's image will be parallel to corresponding sides if the quadrilateral is rotated 180°.

The attachment shows a quadrilateral rotated 180°.

__

Additional comment

We assume that the "corresponding side" of AB is A'B' in the image.

If square ABCD is rotated 90°, then side AB will be parallel to side B'C', and the same will be true for 3 other pairs of sides. For the purpose of this question, we don't consider AB and B'C' to be "corresponding" sides.

Answer:

The builder has 28,200m^2 left to build the houses.

Step-by-step explanation:

For the roads,

They are 3m wide and they stretch 200m.

We must find the area for one road and multiply by three.

Area = Length * Width

Area = 200m * 3m

Area = 600m^2

600 * 3 = 1800m^2

1800m^2 is taken up by the three roads.

Next, we must find the total area of the field.

Area = Length * Width

Area = 200m * 150m

Area = 30,000m^2

30,000m^2 is the total area of the field, and we need to subtract the area the roads take up to determine the area left for the houses.

30,000m^2 - 1800m^2 = 28,200m^2

The builder has 28,200m^2 left to build the houses.

The time it takes to evaluate 27 + 72 is not a random variable, because it is a deterministic quantity that does not involve any uncertainty or probability.

The exact time it takes to evaluate 27 + 72 is not a random variable, because it is a deterministic quantity that does not involve any element of chance or uncertainty. The result of the addition is always the same and can be calculated precisely in a finite amount of time.

Random variables, on the other hand, are variables that can take on different values with certain probabilities, and are used to model phenomena that involve uncertainty or randomness. Discrete random variables take on a countable set of values, while continuous random variables take on an uncountably infinite range of values.

In summary, the time it takes to evaluate 27 + 72 is not a random variable, because it is a deterministic quantity that does not involve any uncertainty or probability.

In mathematics, a variable is a symbol or letter that represents a value or quantity that can change or vary. Variables are used to express relationships between different quantities and to solve equations.

For example, in the equation y = 2x + 3, x and y are variables. The value of y depends on the value of x, which can vary. We can solve for the value of y for different values of x, and the solution will be a set of ordered pairs (x, y) that form a straight line when plotted on a graph.

Variables can be used to represent a wide range of quantities, including numbers, vectors, functions, and more. They are an essential tool in many branches of mathematics, including algebra, calculus, and statistics.

In addition to mathematics, variables are also used in many other fields, including science, engineering, and computer programming, to represent quantities that can change or be controlled. In these fields, variables are often used to model complex systems or to simulate experiments, and are a fundamental concept in data analysis and computational thinking.
