11. Dimension of Row Space = 3.

12. Dimension of Row Space = 1.

13. largest possible rank is 5.

14. largest possible dimension is 3.

15. Dimension of Nul A = 2.

Let's discuss it further below.

11. The dimension of the row space of an 8x5 matrix A can be found using the Rank-Nullity theorem, which states that the rank of a matrix (dimension of the row space) plus the dimension of the null space equals the number of columns in the matrix. So, if the null space is 2-dimensional, then the dimension of the row space is:

Dimension of Row Space = 5 (number of columns) - 2 (dimension of null space) = 3.

12. For a 5x6 matrix A, the Rank-Nullity theorem can also be applied. If the null space is 4-dimensional, then the dimension of the row space is:

Dimension of Row Space = 5 (number of rows) - 4 (dimension of null space) = 1.

13. The largest possible rank of a 7x5 matrix A is equal to the minimum of the number of rows and columns, which in this case is 5. For a 5x7 matrix A, the largest possible rank is also the minimum of the number of rows and columns, which is 5.

14. The largest possible dimension of the row space of a 4x3 matrix A is the minimum of the number of rows and columns, which is 3. For a 3x4 matrix A, the largest possible dimension of the row space is also the minimum of the number of rows and columns, which is 3.

15. The smallest possible dimension of Nul A for a 6x8 matrix can be found using the Rank-Nullity theorem. The largest possible rank of a 6x8 matrix A is the minimum of the number of rows and columns, which is 6. Thus, the smallest possible dimension of Nul A is:

Dimension of Nul A = 8 (number of columns) - 6 (largest possible rank) = 2.

The probability that in a random sample of 190 Americans aged 14 or older, more than 27 are single is approximately 0.9975

To solve this problem, we can use the normal approximation to the binomial distribution.

First, we need to calculate the mean and standard deviation of the number of singles in a sample of 190 Americans aged 14 or older.

Mean

μ = n × p = 190 × 0.22 = 41.8

Standard deviation

σ = sqrt(n ×p × (1 - p)) = sqrt(190 × 0.22 × (1 - 0.22)) = 5.27

Now, we can use the standard normal distribution to calculate the probability that more than 27 people in the sample are single. We convert the binomial distribution to a normal distribution by using the following formula

z = (x - μ) / σ

where x is the number of singles in the sample.

z = (27 - 41.8) / 5.27 = -2.80

Using a standard normal distribution table or calculator, we can find that the probability of getting a z-score of -2.80 or lower is approximately 0.0025.

However, we want to find the probability of getting more than 27 singles, so we need to find the area to the right of z = -2.80. This is equivalent to subtracting the probability of getting a z-score of -2.80 or lower from 1:

P(Z > -2.80) = 1 - 0.0025 = 0.9975

Answer:

The Distributed Pattern Matching (DPM) problem have provided mathematical analysis and simulation results for establishing the effectiveness of the proposed architecture. DPMS achieves many desirable properties of both the unstructured and structured P2P systems. Like unstructured systems DPMS supports partial keyword matching, utilizes the heterogeneity in peer capabilities, and does not place any hard restriction on index/document placement. Like structured systems, on the other hand, DPMS attains logarithmic bound on search complexity and offers guarantee on search completeness and discovery of rare items. Advertisement traffic in DPMS is comparable to that of DHT-based structured P2P systems. To our knowledge Distributed Pattern Matching (DPM) problem has never been addressed by any research activity in P2P context. 1 The index distribution architecture of DPMS is unique and has been designed specifically to solve the DPM problem. The novel aggregation scheme, proposed in this paper, can effectively reduce storage overhead at the indexing peers without incurring a significant decrease in query routing performance. However, the use of bloom filter for representing indices is not new. Many network applications use bloom filters. A comprehensive list of such applications can be found in [6]. The rest of this paper is organized as follows. Section II highlights and compares the approaches related to DPMS. The architecture and operation of DPMS are presented in section III. Mathematical analysis of search complexity in DPMS is provided in section IV.

The approximate distance between Khloe and school is given by 18.78 miles.

Representing Khloe's movements on a coordinate plane.

Let us assume that Khloe's starting point (her school) is at the origin (0,0).

She walks 20 miles due west,

which means she moves 20 units to the left on the x-axis. Her new position is (-20,0).

She then walks 8 miles due north,

which means she moves 8 units up on the y-axis.

Her new position is (-20,8).

Finally, she walks 3 miles due east,

which means she moves 3 units to the right on the x-axis.

Her new position is (-17,8).

Distance between Khloe's final position and her starting point (the school),

Use the Pythagorean theorem,

Distance = √((change in x)^2 + (change in y)^2)

⇒Distance = √((-17-0)^2 + (8-0)^2)

⇒Distance = √(289 + 64)

⇒Distance = √353

⇒Distance ≈ 18.78 miles

Therefore, Khloe is approximately 18.78 miles away from her school.

If the number b is 90% less than 47 and the number a is 110% greater than b, then the value of a is 9.87.

If the number b is 90% less than 47, that means b is equal to 10% of 47, which can be calculated as:

b = 0.1 x 47

b = 4.7

If the number a is 110% greater than b, that means a is equal to 100% (or 1) plus 110% (or 1.1) of b, which can be calculated as:

a = (1 + 1.1) x b

Then we can fill out the table of joint relative frequency as follows:

               Small        Large

Male         5/50        18/50

Female    21/50        6/50

Joint relative frequency is a statistical term that refers to the proportion of individuals in a population that share two or more specific characteristics. In other words, it measures the frequency or occurrence of a specific combination of two or more variables within a larger population.

Here,

To find the joint relative frequencies, we need to divide each cell by the total number of people (males + females).

Here, we added up the number of males and females to get the total number of people (50). Then, we divided the number of males who ordered a small sandwich (5) by 50 to get the relative frequency of males who ordered a small sandwich (5/50), and so on for each cell in the table.

To calculate the joint relative frequencies, we need to divide each cell in the second table by the total number of observations, which is the sum of all cells in the first table.

The total number of observations is:

5 + 18 + 21 + 6 = 50

To calculate the joint relative frequency for the first cell (small sandwich, male), we divide the number of observations in that cell by the total number of observations:

joint relative frequency = 5/50 = 0.1

Note that the sum of the relative frequencies in each column should add up to 1, since we are dividing by the total number of people.

There are two statements that may not be true:

B. If two lines intersect, both lines are in one plane.

F. There is exactly one line through any two points.

Statement B is not true because if two lines intersect at an angle, they are not in the same plane. This is known as skew lines.

Statement F is not true in non-Euclidean geometries, such as spherical or hyperbolic geometry. In these geometries, there can be multiple lines that pass through two points. However, in Euclidean geometry (which is what is typically taught in high school), there is exactly one line that passes through any two points.

The values of x where the function f(x) is not continuous are x = 2, and the discontinuity at x = 2 is a jump discontinuity.

The function f(x) is defined as:

f(x) = {1/2x+5, x<=2

{x+3, x>2

To find the values of x where f(x) is not continuous, we need to check for three types of discontinuities: removable, jump, and infinite.

Removable discontinuity: This occurs when a function has a hole at a certain point, but can be made continuous by defining or redefining the value of the function at that point. In order for a discontinuity to be removable, the limit of the function as x approaches that point must exist.

To check for removable discontinuity, we need to check if the limit of the function as x approaches a certain point exists, but the function value is different from the limit. In this case, we only need to check the function at x = 2.

lim x->2- f(x) = lim x->2- 1/2x+5 = 6

lim x->2+ f(x) = lim x->2+ x+3 = 5

Since the limits from both sides are not equal, there is a removable discontinuity at x = 2. We can redefine the value of f(x) at x = 2 as 6 to remove the discontinuity.

Jump discontinuity: This occurs when the function has two distinct finite limits from both sides of a point, but the limits are not equal.

To check for jump discontinuity, we need to check if the limit of the function as x approaches a certain point exists from both sides, but they are not equal. In this case, we only need to check the function at x = 2.

lim x->2- f(x) = lim x->2- 1/2x+5 = 6

lim x->2+ f(x) = lim x->2+ x+3 = 5

Since the limits from both sides are not equal, there is a jump discontinuity at x = 2.

Infinite discontinuity: This occurs when the function approaches infinity or negative infinity as x approaches a certain point.

To check for infinite discontinuity, we need to check if the limit of the function as x approaches a certain point approaches infinity or negative infinity. In this case, there is no such point where f(x) approaches infinity or negative infinity.

Therefore, the values of x where the function f(x) is not continuous are x = 2, and the discontinuity at x = 2 is a jump discontinuity.

Answer:

Step-by-step explanation:

∠JKL and ∠JML are supplementary( they add to 180°).

Set their values equal to 180 to find the value of x.

15x - 19 + 13x + 3 = 180

Combine like terms

28x - 16 = 180

Add 16 to both sides to isolate the x

28x = 196

Divide both sides by 28

x = 7

Substitute the value of x into the expression for ∠JML

13(7) + 3 = ∠JML

91 + 3 = ∠JML

94° = ∠JML

To check our answer we can substitute the value of x into the expression for ∠JKL and if they add up to 180 we are correct

15(7) - 19 =∠JKL

105 -19 =∠JKL

86 =∠JKL

94° + 86° = 180°

The increase in weekly wages for both the man and the boy is Rs. 40.

Let's assume that the increase in wages for both the man and the boy is x.

After the increase, the man's weekly wage will be Rs. 80 + x and the boy's weekly wage will be Rs. 35 + x.

We know that the man's wage after the increase is 8/5 of the boy's wage after the increase. Mathematically,

80 + x = (8/5)(35 + x)

Simplifying this equation, we get:

80 + x = 56 + (8/5)x

Multiplying both sides by 5, we get:

400 + 5x = 280 + 8x

Subtracting 5x from both sides, we get:

400 = 280 + 3x

Subtracting 280 from both sides, we get:

120 = 3x

Dividing both sides by 3, we get:
