(b) During a housing boom the price of houses increased over an 18 month period. A house that cost 240000 at the start of the period had a sale value of 276000 at the end of the period. What was the average rate of change in the price per month?​

Answers

Answer 1

After answering the presented question, we can conclude that As a result, the average monthly rate of change in price during the housing bubble was $2,000.

What is average rate?

The term "average rate" can have different meanings depending on the context in which it is used. In general, it refers to the amount of change that occurs over a certain period of time, divided by the length of that time period. Here are a few examples of how the term might be used in different fields.

The average monthly rate of change in price can be estimated by dividing the total price change by the number of months:

(final price - beginning price) / number of months = average rate of change

The beginning price was $240,000, the final price was $276,000, and the time duration was 18 months in this example. Hence, using these data, we can calculate the average rate of change as:

(276000 - 240000) / 18 = 36000 / 18 = 2000 Average rate of change

As a result, the average monthly rate of change in price during the housing bubble was $2,000.

A bag contains 6 yellow marbles, 4 red marbles, 8 blue marbles. If one marble is drawn from the bag then replaced, what is the probability of drawing a yellow marble then a blue marble?

Answers

a) the probability of drawing a yellow marble than a blue marble is (1/3) x (4/9) = 4/27.

b) the probability of guessing a number less than 7 is 6/10 or 3/5.

c) the probability of drawing a white marble than a red marble is (2/9) x (6/17) = 4/51.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

Since the marble is replaced after the first draw, the probability of drawing a yellow marble is 6/18 = 1/3.

Similarly, the probability of drawing a blue marble on the second draw is 8/18 = 4/9.

Therefore, the probability of drawing a yellow marble than a blue marble is (1/3) x (4/9) = 4/27.

There are 6 numbers less than 7 (1, 2, 3, 4, 5, 6) and 10 total numbers, so the probability of guessing a number less than 7 is 6/10 or 3/5.

Since the marble is not replaced after the first draw, the probability of drawing a white marble is 4/18 = 2/9.

The probability of drawing a red marble on the second draw, given that a white marble was drawn first, is 6/17.

Therefore, the probability of drawing a white marble than a red marble is (2/9) x (6/17) = 4/51.

Hence, a) the probability of drawing a yellow marble than a blue marble is (1/3) x (4/9) = 4/27.

b) the probability of guessing a number less than 7 is 6/10 or 3/5.

c) the probability of drawing a white marble than a red marble is (2/9) x (6/17) = 4/51.

Find the dimensions and volume of the largest box that can be formed in this way.

Answers

Answer:

3 in × 6 in × 12 in216 in³

Step-by-step explanation:

You want the dimensions and volume of a cuboid that can be made from an 18 in square of cardboard when an x-inch square is cut from two adjacent corners, and an x-inch by 9-inch rectangle is cut from the other two corners.

Dimensions

The longest side of the cuboid will have length (18 -2x). The second longest side will have length (18 -9 -x) = (9 -x). The shortest side will have length x.

Volume

The volume of the cuboid is the product of these side lengths:

  V = (18 -2x)(9 -x)(x) = 2x(9 -x)²

Maximum volume

The value of x that maximizes volume will be the value that makes the derivative with respect to x be zero.

  V' = 2(9 -x)² -4x(9 -x) = (9 -x)(2(9 -x) -4x) = 2(9 -x)(9 -3x)

  V' = 6(9 -x)(3 -x)

The derivative will be zero when its factors are zero, at x=9 and x=3. The value x=9 gives zero volume.

The value x=3 gives a volume of ...

  V = 2·3(9 -3)² = 6³ = 216 . . . . . cubic inches

The dimensions are ...

x = 39 -x = 9 -3 = 618 -2x = 18 -6 = 12

The dimensions for maximum volume are 3 inches by 6 inches by 12 inches. The maximum volume is 216 cubic inches.

1 The points (-8, 5) and (-4, r) lie on a line with slope 1/4. Find the missing coordinate r.​

Answers

Answer:

Step-by-step explanation:

We can use the slope formula to find the slope of the line passing through the two given points:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-8, 5) and (x2, y2) = (-4, r).

Substituting these values, we have:

1/4 = (r - 5) / (-4 - (-8))

1/4 = (r - 5) / 4

r - 5 = 1

r = 6

Therefore, the missing coordinate is r = 6.

The period p of a pendulum, or the time it takes for the pendulum to make one complete swing, varies directly as the square root of the length L of the pendulum. If the period of a pendulum is 1.8 s when the length is 2 ft, find the period when the length is 3 ft.

Answers

The period of the pendulum when the length is 3 ft is approximately 2.08 seconds.

What is the period?

We are given that the period P varies directly as the square root of the length L of the pendulum. We can write this as:

P ∝ √L

Using a proportionality constant k, we can write this as an equation:

P = k√L

To find the value of k, we can use the information given in the problem: when L = 2 ft, P = 1.8 s. Substituting these values into the equation, we get:

1.8 = k√2

To solve for k, we can isolate it by dividing both sides by √2:

k = 1.8 / √2

Now we can use this value of k to find the period when the length is 3 ft. Substituting L = 3 ft and the value of k we just found into the equation, we get:

P = k√L

P = (1.8 / √2) √3

P ≈ 2.08 seconds

Therefore, the period of the pendulum when the length is 3 ft is approximately 2.08 seconds.

Topic: Linear Diophantine Equation
Solve: Find x,y∈Z such that 123x + 360y = 99

Answers

The solution to the equation 123x + 360y = 99 is x = 22 and y = -11.

What is Linear Diophantine Equation?

An equation with two or more integer unknowns that are all to a maximum degree of one is known as a linear diophantine equation (LDE).

To solve the equation 123x + 360y = 99, we can use the extended Euclidean algorithm, which is a method for finding the greatest common divisor (GCD) of two integers and expressing it as a linear combination of those integers. We can use the same algorithm to find a solution to the given equation.

First, we need to find the GCD of 123 and 360. We can use the Euclidean algorithm for this:

gcd(123, 360) = gcd(123, 360 - 123*2) = gcd(123, 114)

gcd(123, 114) = gcd(123 - 114, 114) = gcd(9, 114)

gcd(9, 114) = gcd(9, 114 - 9*12) = gcd(9, 6)

gcd(9, 6) = gcd(9 - 6*1, 6) = gcd(3, 6)

gcd(3, 6) = gcd(3, 6 - 3*2) = gcd(3, 0)

gcd(3, 0) = 3

Therefore, the GCD of 123 and 360 is 3.

Now we can use the extended Euclidean algorithm to find integers s and t such that 123s + 360t = 3. This is done by working backwards through the Euclidean algorithm and expressing each remainder as a linear combination of the previous two integers:

gcd(123, 360) = 3

3 = 123s + 360t

3 = 9 - 114

 = 9 - (360 - 123*2)

 = 123*2 - 360*1

s = 2, t = -1

Now we can multiply both sides of the equation by 33 to get a solution to the original equation:

123x + 360y = 99

123*2*33 + 360*(-1)*33 = 3*33

123*66 + 360*(-33) = 99

Finally, we can divide both sides by 3 to get a solution in integers:

123*22 + 360*(-11) = 33

Therefore, x = 22 and y = -11 is a solution to the equation 123x + 360y = 99.

Answers

1. x + 30 = 98 equation says that Jerome's total earnings y for the day is equal to his wages.

2. y = 68 + 30 equation says that Jerome's total earnings y for the day is equal to his wages.

What is equation?

A statement that affirms the equality of two expressions connected by the equals symbol "=" is known as an equation. For illustration, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. These two expressions are joined together by the sign "=".

There are different ways to represent this situation algebraically, but here are two possible equations:

1. Let x be the amount of money Jerome earns in wages, then the equation can be written as:

x + 30 = 98

This equation says that the sum of Jerome's wages x and his tips of $30 is equal to his total earnings of $98 for the day.

2. Alternatively, we can let y be the total amount of money Jerome makes for the day (including tips), then we can write:

y = 68 + 30

This equation says that Jerome's total earnings y for the day is equal to his wages of $68 plus his tips of $30.

Write the statement in words. Let p="The plane is on time." Let q="The sky is clear."
Q->~P

Answers

The statement can be read as "If the sky is clear, then the plane is not on time."

What is the conditional statement?

A conditional statement is a logical statement that has two parts: an antecedent (also called a hypothesis) and a consequent (also called a conclusion). The statement asserts that if the antecedent is true, then the consequent must also be true.

The statement "Q -> ~P" is an example of a conditional statement in symbolic logic.

In this case, Q represents "The sky is clear" and ~P represents "The plane is not on time" (the tilde symbol ~ negates the truth value of P).

The arrow symbol -> means "implies" or "if...then". Therefore, the statement can be read as "If the sky is clear, then the plane is not on time."

In other words, the statement is saying that if the sky is clear, then it is not possible for the plane to be on time.

This is because the statement implies that the plane being on time is dependent on the sky not being clear. So if the sky is clear, it means that the conditions for the plane to be on time are not present, and therefore the plane is not on time.

It's worth noting that the statement does not say anything about what happens if the sky is not clear.

It's possible that the plane could still be on time even if the sky is not clear, according to this statement.

Hence, the statement can be read as "If the sky is clear, then the plane is not on time."

Point A is located at (-3, -5). If point B is 11 units away and is located in quadrant 2, what are the coordinates for point B?

Answers

The answer of the given question based on the graph is  the coordinates of point B are (-8, 4).

What is Quadrant?

A quadrant is one of four regions into which coordinate plane is divided by x-axis and y-axis. The x-axis is horizontal axis and the y-axis is vertical axis. The quadrants are labeled using Roman numerals, starting in upper right quadrant and moving counterclockwise.

Since point B is 11 units away from point A, we know that the distance between them is:

d = √((x2 - x1)² + (y2 - y1)²) = 11

where (x1, y1) = (-3, -5) are the coordinates of point A, and (x2, y2) are the coordinates of point B.

We also know that point B is located in quadrant 2, which means that its x-coordinate is negative and its y-coordinate is positive.

To find the coordinates of point B, we can use the distance formula and the fact that point B is in quadrant 2:

d = √((x2 - x1)² + (y2 - y1)²) => 11 = √((x2 - (-3))² + (y2 - (-5))²)

Since point B is in quadrant 2, its x-coordinate is negative and its y-coordinate is positive:

x2 < 0, y2 > 0

We can choose any values for x2 and y2 that satisfy these conditions and the distance formula equation. Let's choose x2 = -8 and y2 = 4:

11 = √((-8 - (-3))² + (4 - (-5))²)

11 = √(25 + 81)

11 = √106

Therefore, coordinates of point B is (-8, 4).

Answers

the probability of selecting a tool produced by the old method on the first attempt and a tool produced by the new method on the second attempt is:

P(A and B) = P(A) * P(B | A) = 0.8305 * 0.1998 = 0.1660

How to solve the questions?

Part A:

Let A be the event that the first tool selected is acceptable and B be the event that the second tool selected is acceptable.

We need to find the probability of P(A and B), which can be calculated using the multiplication rule of probability as follows:

P(A and B) = P(A) * P(B | A)

where P(A) is the probability of selecting an acceptable tool on the first attempt and P(B | A) is the conditional probability of selecting an acceptable tool on the second attempt given that the first tool selected was acceptable.

P(A) = (1640 + 328) / (1640 + 328 + 23 + 9) = 0.985

P(B | A) = (1639 + 327) / (1640 + 328 + 23 + 9 - 1) = 0.985

Therefore, the probability of both selections being acceptable is:

P(A and B) = P(A) * P(B | A) = 0.985 * 0.985 = 0.9702

The events are dependent because the probability of selecting an acceptable tool on the second attempt depends on the result of the first attempt.

Part B:

Let A be the event that the first tool selected is produced by the old method and B be the event that the second tool selected is produced by the new method.

We need to find the probability of P(A and B), which can be calculated using the multiplication rule of probability as follows:

P(A and B) = P(A) * P(B | A)

where P(A) is the probability of selecting a tool produced by the old method on the first attempt and P(B | A) is the conditional probability of selecting a tool produced by the new method on the second attempt given that the first tool selected was produced by the old method.

P(A) = (1640 + 23) / (1640 + 328 + 23 + 9) = 0.8305

P(B | A) = 328 / (1640 + 328 + 23 + 9 - 1) = 0.1998

Therefore, the probability of selecting a tool produced by the old method on the first attempt and a tool produced by the new method on the second attempt is:

P(A and B) = P(A) * P(B | A) = 0.8305 * 0.1998 = 0.1660

The events are dependent because the probability of selecting a tool produced by the new method on the second attempt depends on the result of the first attempt.

The process of numerical integration involves applying numerical techniques to approximate the value of a determined integral of a function across a specified interval. To approximate integrals that are challenging or impossible to solve analytically, it is employed in calculus.

Numerical integration works by breaking the integration interval into smaller subintervals, approximating the function over each subinterval with a simple function, and then summing the areas under the curve of the approximating function over each subinterval to estimate the integral.

Determine the value of f(xi):

f(x1) = (0-2)^3 = (-2)³ = -8

f(x2) = (1-2)^3 = (-1)³ = -1

f(x3) = (2-2)^3 = 0³ = 0

f(x4) = (3-2)^3 = 1³ = 1

f(x5) = (4-2)^3 = 2³ = 8

f(x6) = (5-2)^3 = 3³ = 27

Substituting the value in the given summation we have:

Σ i = 1 to 6 f(xi) Δ x = f(x1) Δ x + f(x2) Δ x + f(x3) Δ x + f(x4) Δ x + f(x5) Δ x + f(x6) Δ x

= (-8)(0.1) + (-1)(0.1) + (0)(0.1) + (1)(0.1) + (8)(0.1) + (27)(0.1)

= -0.5 + (-0.1) + 0 + 0.1

= 3

Hence, the sum is equal to 3.

b. The number of ways to select three Republicans from the group of six Republicans is 20.

c. The probability is 1/6.

What is probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is essentially what probability means.

a. The number of ways to select three people from a group of ten is given by the combination formula:

C(10,3) = 10! / (3! * (10 - 3)!) = 120

Therefore, there are 120 ways to select three people from this group of ten.

b. The number of ways to select three Republicans from the six Republicans is given by the combination formula:

C(6,3) = 6! / (3! * (6 - 3)!) = 20

Therefore, there are 20 ways to select three Republicans from the six Republicans.

c. The probability of selecting all Republicans is the number of ways to select three Republicans divided by the total number of ways to select three people:

P(all Republicans) = C(6,3) / C(10,3) = 20/120 = 1/6

Therefore, the probability that the selected group will consist of all Republicans is 1/6.

What is 1/2% to a ratio ?

Answers

To convert 1/2% to a ratio, we first convert it to a decimal by dividing by 100:

1/2% = 1/2 ÷ 100 = 0.005

Then we express this decimal as a ratio by putting it in the form of x:y:

0.005 = x:y

To simplify this ratio, we can multiply both sides by a factor that will make x and y whole numbers. For example, we can multiply both sides by 100:

0.005 × 100 = x:y × 100

0.5 = x:y

So 1/2% as a ratio is 1:200.

1/2% is equivalent to 0.5% or 0.005 as a decimal.

To express 0.005 as a ratio, you can write it as a fraction with a numerator of 0.005 and a denominator of 1. Then, you can multiply both the numerator and denominator by 100 to get rid of the decimal and express it as a ratio.

0.005/1 = (0.005

Therefore, 1/2% is equivalent to the ratio 0.5:100 or 1:200.

Un chef observó que el 65 % de todos sus clientes consume mayonesa, el 70 % consume kétchup y el 80 % consume mayonesa o kétchup. ¿Cuál es la probabilidad de que un cliente consuma las dos salsas al mismo tiempo​

Answers

The probability that a customer Consumes both mayonnaise and ketchup at the same time is 0.55 or 55%.

To find the probability that a customer consumes both mayonnaise and ketchup at the same time, we need to use the concept of intersection in probability theory. The intersection represents the overlap or commonality between two events, in this case, the consumption of mayonnaise and ketchup.

Given that 80% of customers consume either mayonnaise or ketchup, we can assume that this includes the customers who consume both. Let's call the event of consuming mayonnaise "M" and the event of consuming ketchup "K". Therefore, we know that P(M U K) = 0.8.

To find the probability of consuming both, we can use the formula P(M ∩ K) = P(M) + P(K) - P(M U K), where ∩ represents the intersection. We can substitute the values we have been given to get:

P(M ∩ K) = 0.65 + 0.70 - 0.8 = 0.55

Therefore, the probability that a customer consumes both mayonnaise and ketchup at the same time is 0.55 or 55%. This means that more than half of the customers consume both, indicating that the chef could consider offering dishes that combine both sauces to cater to this preference.

There is a 20% chance that a particular volcano will erupt during any given decade. A random number generator generated 10 sets of random numbers from 1 to 5 as shown. The number 1 represents the volcano erupting. Find the experimental probability that the volcano will erupt in 1 or 2 of the next 5 decades

Answers

The experimental probability of the volcano erupting in 1 or 2 of the next 5 decades is 6/10 or 0.6.

We can do this by assigning a value of 1 to the numbers 1 and 2 (representing the volcano erupting) and a value of 0 to

the numbers 3, 4, and 5 (representing the volcano not erupting).

For each set of random numbers generated, we can count the number of times the volcano erupted (i.e. the sum of the

values assigned to the numbers 1 and 2).

Out of the 10 sets of random numbers generated, we might get results like this:
Set 1: 1 3 4 2 1 (2 eruptions)
Set 2: 2 1 5 4 3 (2 eruptions)
Set 3: 3 2 5 4 5 (1 eruption)
Set 4: 1 1 2 4 5 (3 eruptions)
Set 5: 4 4 4 4 4 (0 eruptions)
Set 6: 1 1 1 1 1 (5 eruptions)
Set 7: 3 3 3 3 3 (0 eruptions)
Set 8: 2 2 2 2 2 (0 eruptions)
Set 9: 1 2 1 2 1 (4 eruptions)
Set 10: 5 5 5 5 5 (0 eruptions)

Out of these 10 sets, we can see that there were 6 sets where the volcano erupted in 1 or 2 of the next 5 decades (sets

1, 2, 3, 4, 9, and 10). Therefore, the experimental probability of the volcano erupting in 1 or 2 of the next 5 decades is

6/10 or 0.6.

People have considered the possibility that the missing colonists could have assimilated into nearby Native American tribes since at least 1605. If this integration was successful, the assimilated colonists would gradually exhaust their European supplies (ammunition, clothing) and discard European culture (language, style of dress, agriculture) as Algonquian lifestyle became more convenient. Colonial era Europeans observed that many people removed from European society by Native Americans for substantial periods of timeeven if captured or enslavedwere reluctant to return; the reverse was seldom true. Therefore, it is reasonable to postulate that, if the colonists were assimilated, they or their descendants would not seek reintegration with subsequent English settlers.
