If the points were scattered around the graph with no common theme or pattern, it would be none.

The height of the rectangle will be 17 feet.

Let H be the height and W be the width of the rectangle.

Then the perimeter of the rectangle will be

Perimeter of the rectangle = 2(H + W) units

A rectangle has a perimeter of 45 feet and a base of 5.5 feet.

The sum of all the sides of the rectangle will be known as the perimeter of the rectangle.

Then the height of the rectangle will be

45 = 2(H + 5.5)

22.5 = H + 5.5

H = 22.5 - 5.5

H = 17 feet

Thus, the height of the rectangle will be 17 feet.

The chi-square test of independence is typically used to analyze the relationship between two variables when both variables are nominal, the two variables have been measured on different individuals and the observations on each variable are within-subjects in nature. The answer is  D. all of the above

The chi-square test of independence is a statistical test that is used to determine if there is a significant association between two categorical variables. It is commonly used when both variables are nominal, meaning they consist of categories or groups rather than numerical values.

When conducting the chi-square test of independence, the data is typically collected by measuring the two variables on different individuals or units.

For example, researchers may collect data on the gender (nominal variable) and political affiliation (nominal variable) of different individuals and analyze whether there is a relationship between the two variables.

The test examines the observed frequencies of the different categories in a contingency table and compares them to the expected frequencies under the assumption of independence. If the observed and expected frequencies significantly differ, it suggests that there is an association between the two variables.

Therefore, the chi-square test of independence is applicable when both variables are nominal and the data is collected on different individuals. This allows researchers to investigate the relationship between the variables and determine if they are associated or independent.

As we are already given that the population of gas mileage follows a normal distribution with a mean of 24 miles per gallon and a standard deviation of 6 miles per gallon, i.e., μ = 24 and σ = 6. We need to find the probability that a car will get exactly 22 miles-per-gallon.

We know that the probability density function for the normal distribution is given by: f(x) = (1/σ√(2π))e^(-(x-μ)²/2σ²)Putting the given values in the above formula: f(x) = (1/6√(2π))e^(-(x-24)²/2(6)²).

We need to find f(22), so putting x = 22 in the above formula, we get: f(22) = (1/6√(2π))e^(-(22-24)²/2(6)²)f(22) = (1/6√(2π))e^(-4/36)f(22) = (1/6√(2π))e^(-1/9)f(22) = (1/6√(2π)) × 0.8767 (rounded off to four decimal places) f(22) = 0.0451 (rounded off to four decimal places).

Therefore, the probability that a car will get exactly 22 miles-per-gallon is 0.0451 or 4.51% (rounded off to two decimal places).

Danielle spent x dolar on lunch.

Three times as much on transportation, which can be written as 3x

Then,$4 less on a book that she did on transportation, so 3x-4

If she spent $59, we can equal all the expressions to this value.

Therefofore:

x + (3x) +(3x-4) = 59

To find how much she sped on lunch, we need to solve for x:

x + 3x + 3x - 4 = 59

Solve the like terms:

7x -4 = 59

Add both sides 4 units:

7x -4 +4 = 59 + 4

7x = 63

Divide both sides by 7:

7x/7 = 63/7

x = 9

Hence, Danielle spent $9 dollars on lunch.

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

Answer:

Explained below.

Step-by-step explanation:

The data provided is as follows:

S = {31.5, 36.0, 37.8, 38.5, 40.1, 42.2, 34.2, 36.2, 38.1, 38.7, 40.6, 42.5, 34.7. 37.3, 38.2, 39.5, 41.4, 43.4, 35.6, 37.6, 38.4, 39.6, 41.7, 49.3}

Compute the mean and standard deviation as follows:

\(\mu=\frac{1}{n}\sum X=\frac{1}{24}\times [31.5+36.0+37.8+...+49.3]=38.88\\\\\sigma=\sqrt{\frac{1}{n-1}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{24-1}\times 299.639584}=3.61\)

(a)

Compute the​ z-score corresponding to the individual who obtained 32.3 miles per gallon as follows:

\(z=\frac{X-\mu}{\sigma}\)

  \(=\frac{32.3-38.88}{3.61}\\\\=-1.823\)

Thus, the z-score corresponding to the individual who obtained 32.3 miles per gallon is -1.823.

(b)

The data set arranged in ascending order is:

S = {31.5 , 34.2 , 34.7 , 35.6 , 36 .0, 36.2 , 37.3 , 37.6 , 37.8 , 38.1 , 38.2 , 38.4 , 38.5 , 38.7 , 39.5 , 39.6 , 40.1 , 40.6 , 41.4 , 41.7 , 42.2 , 42.5 , 43.4 , 49.3}

The set consists of 24 values.

The first and third quartile are:

\(Q_{1}=[\frac{n+1}{4}]^{th}\ obs.=[\frac{24+1}{4}]^{th}\ obs.=12.5^{th}\ obs.=\frac{36.2+ 37.3}{2}=36.75\\\\Q_{3}=[\frac{3(n+1)}{4}]^{th}\ obs.=[\frac{3(24+1)}{4}]^{th}\ obs.=18.75^{th}\ obs.=\frac{40.6+41.4}{2}=41\)

Thus, the value of Q₁ is 36.75 and Q₃ = 41.

(c)

Compute the inter-quartile​ range as follows:

\(IQR=Q_{3}-Q_{1}=41-36.75=4.25\)

The inter-quartile range is 4.25.

The inter-quartile range is the amount of data that is contained within the middle 50% of a set of observations, when arranged in order. It is the distance between the first and third quartile.

(d)

Compute the values of lower and upper fences as follows:

\(\text{Lower fence}=Q_{1}-1.5\times IQR=36.75-(1.5\times 4.25)=30.375\approx 30.38\\\\\text{Upper fence}=Q_{3}+1.5\times IQR=41+(1.5\times 4.25)=47.375\approx 47.38\)

Any values that are less than the lower fence or more than the upper fence are considered as outlier.

Consider the arranged data set.

Only one value is more than the upper fence, 47.38, i.e. 49.3.

So, yes there is one outlier, i.e. 49.3.

In summary, the correct statements are 1 and 3. The conservation of momentum requires no external forces acting on a system, while the velocity of the center of mass changes only in the presence of a net external force.

To determine the validity of the given statements, let's break them down and provide a more readable explanation:

1. For the total linear momentum of a system to be conserved, there must be no external forces acting on the system.

This statement is true. According to the law of conservation of momentum, the total linear momentum of an isolated system remains constant if there are no external forces acting on it. Mathematically, this can be expressed as:

ΣP_initial = ΣP_final

where ΣP_initial is the initial total momentum of the system and ΣP_final is the final total momentum of the system.

2. The conservation of momentum depends on the conservation of energy.

This statement is false. The conservation of momentum is a separate principle from the conservation of energy. While both concepts are important in physics, they are distinct and independent of each other. Conservation of momentum is related to the balance of linear motion, while conservation of energy deals with the balance of different forms of energy in a system.

3. The velocity of the center of mass of a system changes only when there is a net external force on the system.

This statement is true. The center of mass of a system is a point that represents the average position of all the mass in the system. The velocity of the center of mass can only change if there is a net external force acting on the system. In the absence of external forces, the center of mass will continue to move with a constant velocity. This principle is derived from the conservation of momentum.

4. The correct statements are 1 and 3, because statements 1 and 3 are true.

This statement is true. Based on the explanations above, statements 1 and 3 are indeed true. Statement 2 is false because conservation of momentum does not depend on the conservation of energy. Therefore, statement 4 is also false.

The least distance from point P to line l is approximately equal to 3.536 units.

There are several ways to calculate the least distance, in this case we decided to use the approach based on vectors and projections. First, we generate two auxiliary vectors:

Vector parallel to the line l

\(\overrightarrow {AB} = (5, 1) - (2, 4)\)

\(\overrightarrow{AB} = (3, - 3)\)

A vector from one point on the line l to the point P

\(\overrightarrow{AP} = (1, 1) - (2, 4)\)

\(\overrightarrow {AP} = (- 1, - 3)\)

Now we proceed to find the vector distance by using the following vectorial formula:

\(\vec d = \frac{\overrightarrow{AP} \,\bullet\, \overrightarrow {AB}}{\overrightarrow {AB} \,\bullet \,\overrightarrow {AB}} \cdot \overrightarrow{AB} - \overrightarrow {AP}\)

\(\vec d = \frac{(-1)\cdot (3) + (- 3) \cdot (- 3)}{3^{2}+ (-3)^{2}} \cdot (3, - 3) - (-1, - 3)\)

\(\vec d = - \frac{1}{6}\cdot (3, - 3) - (- 1, - 3)\)

\(\vec d = \left(-\frac{1}{2}, \frac{1}{2} \right) + (1, 3)\)

\(\vec d = \left(\frac{1}{2}, \frac{7}{2} \right)\)

The magnitude of the vector distance is determined by Pythagorean theorem:

\(d = \sqrt{\left(\frac{1}{2} \right)^{2}+\left(\frac{7}{2} \right)^{2}}\)

d ≈ 3.536

The least distance from point P to line l is approximately equal to 3.536 units.
