A) The area of parallelogram 1 is 4 square units greater than the area of parallelogram 2.

The area of parallelogram 1 is 2 square units greater than the area of parallelogram. Option 2 is correct.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

A₁ is the area of parallelogram 1

A₁ is the area of parallelogram 2

l₁ is the distance between the points (2,6),(0,2)

l₂ is the distance between the points (4,0)(0,2)

b₁ is the distance between the points (2,0),(0,-2)

b₂ is the distance between the points (2,6),(4,-6)

A₁ =  l₁ × b₁

A₁=4.47 ×4.47

A₁  = 19.89 sq.unit

A₂=l₂×b₂

A₂=2.82 × 6.342

A₂=17.88 sq.unit

A₁-A₂ = 19.89 sq.unit - 17.88  sq.unit'

A₁-A₂= 2.01

The area of parallelogram 1 is 2 square units greater than the area of a parallelogram.

Hence,option 2 is correct.

The next permutation after 614532 in the lexicographic ordering of the permutations of the set {1, 2, 3, 4, 5, 6} is 614523.

To find the next permutation, we need to identify the rightmost element that can be increased while keeping the remaining elements in non-increasing order.

In the given permutation 614532, the rightmost element that can be increased is 3 because the remaining elements, 2 and 5, are in non-increasing order.

Next, we need to find the smallest element larger than 3 among the elements to the right of 3. In this case, that element is 5.We swap the elements 3 and 5, resulting in the permutation 614523.

Finally, we need to sort the remaining elements in non-decreasing order to obtain the next lexicographically ordered permutation. In this case, the remaining elements are 2 and 3, which are already in non-decreasing order.

Therefore, the next permutation after 614532 is 614523.

What is algebra ?

Algebra is a branch of mathematics that deals with mathematical symbols and the rules for manipulating these symbols. It is a way to represent mathematical relations and to reason about them. Algebraic concepts include using variables (such as x or y) to represent unknown values, using operations such as addition, subtraction, multiplication and division.

We know that ,

Angela = 12 books

Inola = 1/3v less than Angela

To find the value of v, we can set up the proportion ,

12 = v + 1/3v

We can then solve for v by multiplying both sides by 3 ,

12*3 = 3v + v

36 = 4v

So, v = 9

Inola checked out 1/3v less than Angela, which is ,

1/3 * 9 = 3

So, Angela check out 12 library book and Inola check out 1/3v then Inola checked out 12 - 3 = 9 books.

Step-by-step explanation:

Answer as an improper fraction = 30/8 miles

Answer as a mixed number = 3 & 3/4 miles

Answer in decimal form = 3.75 miles

============================================================

How to get that answer:

Let's start with what we're given

Assuming this site is a rectangle, then we can say:

area = length*width

5/8 = (1/6)*w

(5/8)*(6/1) = w

(5*6)/(8*1) = w

30/8 = w

w = 30/8

The answer as an improper fraction is 30/8 miles.

If you want to convert that to a mixed number, then,

30/8 = (24+6)/8

30/8 = 24/8 + 6/8

30/8 = 3 + 3/4

30/8 = 3 & 3/4

The answer as a mixed number is 3 & 3/4 miles

Meaning the width is a full 3 miles wide, plus an additional 3/4 of a mile as well.

In decimal form, the answer is 3.75 miles

A good residual plot should have the points randomly scattered around the horizontal line with no discernible pattern.

This indicates that the model is well fit to the data. The residuals should also be equally distributed on either side of the horizontal line. This can be seen as the sum of the residuals being equal to 0, or mathematically expressed as the sum of the residuals (e) being equal to 0, where \(e = y - ŷ\), where y is the observed value and ŷ is the predicted value. The equation can be expressed as Σe=0.

The area under the standard normal curve between z = 0.5 and z = 1.4, denoted as P(0.5 < z < 1.4), can be found using the cumulative distribution function (CDF) of the standard normal distribution. The correct answer for this probability is option iii. 0.9192.

To calculate P(0.5 < z < 1.4), we need to find the probability of z being less than 1.4 (P(z < 1.4)) and subtract the probability of z being less than 0.5 (P(z < 0.5)) from it. By using a standard normal distribution table or a statistical software, we can find that P(z < 1.4) is approximately 0.9192 and P(z < 0.5) is approximately 0.3085. Therefore, P(0.5 < z < 1.4) is approximately 0.9192 - 0.3085 = 0.6107.

In summary, the correct answer for P(0.5 < z < 1.4) is option iii. 0.9192. This probability represents the area under the standard normal curve between z = 0.5 and z = 1.4. It can be calculated by subtracting the cumulative probability of z < 0.5 from the cumulative probability of z < 1.4.

To find the limit as t approaches 2 of the expression (√(2-t)i + ln(t)j - 1/tk), we can substitute t = 2 into the expression. The limit evaluates to (-1i + ln(2)j - 1/2k).

The given expression (√(2-t)i + ln(t)j - 1/tk) involves three components: the term with i, the term with j, and the term with k. We can evaluate each component separately to find the limit.

Substituting t = 2 into the first component, (√(2-t)i), we get (√(2-2)i) = 0i = 0.

Substituting t = 2 into the second component, (ln(t)j), we get (ln(2)j).

Substituting t = 2 into the third component, (-1/tk), we get (-1/2k).

Putting all the components together, the limit as t approaches 2 of the given expression is: lim┬(t→2)⁡〖(√(2-t i )+ In(t)j-1/t k)^ 〗= (0i + ln(2)j - 1/2k) = -1/2k + ln(2)j.

The answer is either A. IQR, because Sunny Town is symmetric or B. IQR, because Beach Town is skewed.

A distribution refers to the pattern of how data is spread out or distributed across different values or intervals. It is a way to describe and analyze the shape, center, and spread of a set of data.

To determine the location with the most consistent temperature, we need to measure the variability of the temperature data in both locations. The measure of variability that is appropriate for this purpose is the interquartile range (IQR), which measures the spread of the middle 50% of the data.

Therefore, the answer is either A. IQR, because Sunny Town is symmetric or B. IQR, because Beach Town is skewed, depending on the shape of the distributions. If the temperature data in Sunny Town is symmetric, then the IQR would be appropriate to measure the spread of the data. If the temperature data in Beach Town is skewed, then the IQR would also be appropriate to measure the spread of the data. However, if the temperature data in either location is not skewed, then the range would not be an appropriate measure of variability.

The length of x in given triangle is BD = 10 units.

What is Pythagoras theorem ?

Pythagoras theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It can be written as:

\(c^2 = a^2 + b^2\)

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

According to the question:
Using Pythagoras theorem in triangle ABD, we have:

AD² + BD² = AB²

Since AD is the perpendicular from A to BC, it is also the height of the triangle ABC. Hence, we can use the area formula for a triangle:

Area(ABC) = 1/2 * AB * AD

On the other hand, we can also express the area of ABC using the base BC:

Area(ABC) = 1/2 * BC * h

where h is the length of the perpendicular from A to BC, which is the same as AD.

Equating the two expressions for the area of ABC, we get:

1/2 * AB * AD = 1/2 * BC * AD

Simplifying, we get:

AB = BC * (BD / AD)

Substituting the given values, we get:

20 = 30 * (x / AD)

AD = 30/2 = 15 (since the perpendicular from A to BC bisects BC)

Substituting AD into the equation above, we get:

20 = 30 * (x / 15)

Solving for x, we get:

x = 10

Therefore, BD = 10 units.

We can express √832 as 4(2√13).

A definite integral of a function can be represented as the signed area of the region bounded by its graph.

Given is the root of 832 or √832.

Assume that {4n} is equal to {y}. So, we can write -

y = 4n

Squaring both sides, we get -

y² = (4n)² = (√832)²

y² = 16n² = 832

16n² = 832

n² = (832/16)

n² = 52

n = √52

n = 2√13

(b) A is a 3-by-3 matrix and the basis for the nullspace has only 2 vectors, the rank of A is 3 (the maximum possible rank for a 3-by-3 matrix).

(c)  A is invertible.

a. To find a nontrivial vector in the row space of A, we can take the transpose of the basis for the nullspace. Since the nullspace basis is given as {[1 0 5], [1 1 2]}, the nontrivial vector in the row space would be obtained by transposing one of these vectors. Let's choose the first vector [1 0 5] and take its transpose: [1, 0, 5]. This vector belongs to the row space of A and is nontrivial since it is not the zero vector.

b. The rank of a matrix is defined as the maximum number of linearly independent rows or columns. Since A is a 3-by-3 matrix and the basis for the nullspace has only 2 vectors, the rank of A is 3 (the maximum possible rank for a 3-by-3 matrix).

c. A matrix is invertible if and only if its rank is equal to its number of columns. In this case, since the rank of A is 3 and the number of columns is also 3, the rank condition for invertibility is satisfied. Therefore, A is invertible.
