From the given information provided, the means of x₁, x₂,  and x₃ are 158.28, 41.3, and 43.75 respectively.

a. Handle the missing values using omission strategy:

The omission strategy involves removing any observation with missing values.

The resulting table after the omission strategy is as follows:

Obs x₁ x₂ x₃

1 248 3.5 3.8

2 55 150 74

3 196 4.5 32

4 134 6.2 63

We can see that one observation with missing values was removed, which was observation 5.

b. Handle the missing values using simple mean imputation strategy:

The simple mean imputation strategy involves replacing the missing values with the mean of the non-missing values.

The means of x₁, x₂, and x₃ are calculated as follows:

mean of x₁ = (248 + 55 + 196 + 134) / 4 = 158.25

mean of x₂ = (3.5 + 150 + 4.5 + 6.2) / 4 = 41.3

mean of x₃ = (3.8 + 74 + 32 + 63) / 4 = 43.75

The resulting table after the simple mean imputation strategy is as follows:

Obs x₁ x₂ x₃

1 248 3.5 3.8

2 55 150 74

3 196 4.5 32

4 134 6.2 63

5 158.25 41.3 43.75

We can see that all missing values were replaced, which were x₁ in observation 5 and x₃ in observation 3.

Converting the percentage to degree in the pie chart, angle PQ and UPT are 162° and 25.2° respectively

This is a statistical tool used to represent data in a chart. It is often represented using angles or percentage.

To find the value of the respectively angles, we have to convert the values from percentage to degree.

The formula to do this is given as

Percentage = angle * (100 / 360)

A)

Angle PQ = ?

Substituting the values;

45 = angle * (100 / 360)

45 = angle * (5/18)

angle = 45 / (5/18)

angle = 162°

B) Angle UPT = ?

7 = angle * (5/18)

angle = 7 / (5/18)

angle = 25.2

The angle PQ is 162 degrees, the angle UPT is 25.2 degrees

The decimal construction of 5 /13 repeats and can be written as 0 384615384615 .The 99th digit to the right of the decimal point in the decimal construction of 5/13 is 4.

To find the 99th digit to the right of the decimal point in the repeating decimal construction of 5/13, we need to determine the repeating pattern of the decimal representation.

The pattern in the decimal construction of 5/13 is 384615 repeating. This pattern consists of six digits: 3, 8, 4, 6, 1, and 5, which repeat indefinitely.

Since the pattern repeats every six digits, we can divide 99 by 6 to find the number of complete repetitions. The quotient is 16, and the remainder is 3.

The first three digits in the repeating pattern are 3, 8, and 4. Therefore, the 99th digit to the right of the decimal point will be the third digit of the repeating pattern, which is 4.

The 99th digit to the right of the decimal point in the decimal construction of 5/13 is 4.

No, the sample mean does not always have to correspond to one of the observations in the sample. The sample mean is calculated by summing up all the observations in the sample and dividing it by the total number of observations. It represents the average value of the sample.

In some cases, the sample mean may coincide with one of the observations if that particular observation holds a significant weight in determining the overall average. However, in most cases, the sample mean will be a value that falls between the individual observations.

For example, consider a sample with the observations: 5, 7, 9, 11, and 13. The sum of these observations is 45, and there are a total of 5 observations. The sample mean in this case is 45/5 = 9. However, none of the observations in the sample is exactly equal to 9.

Therefore, while the sample mean represents the average value of the sample, it does not necessarily correspond to one of the specific observations in the sample. It is a calculated value that provides a summary measure of the central tendency of the sample data.

From the table, the function f(x) decreases from x = -3 to x = -1 and x = 1 and x = 2

So, we make use of the intervals

x = -1, 0 and 1

From the table,

From x = -1 to 0, the change is 3

From x =  0 to 1, the change is 3

From x =  -1 to 1, the change is 6

Answer:

100 inches (using the given data)

98.43 (using exact numbers)

Step-by-step explanation:

1 inch = 2.54 centimeters

20 inches = 50.8 centimeters, but for the purpose of answering this question we will assume that 20 inches = 0.5 meters (instead of 0.58).

we must solve the following equation:

20 inches / 0.5 meters = X inches / 2.5 meters

(2.5  meters x 20 inches) / 0.5 meters = X inches

20 inches x 5 = X inches

100 inches = X inches

if we do the exact calculation, 2.5 meters in inches = 250 centimeters / 2.54 centimeters per inch = 98.43 inches

A junction is a place where two lines come together or cross. In the illustration above, "point K is the intersection of line segments PQ and AB" is what we would state. The phrase "the line segment PQ crosses AB at position K" is another option.

Keep in mind that two line segments do not always need to intersect. In the illustration above, move point B higher until the intersection of the two line segments disappears. However, keep in mind that lines (as opposed to line segments) continue indefinitely in both directions, thus unless they are absolutely parallel, they will always cross someplace.

It will take approximately 12.25 years for the initial deposit of $12000 to triple itself with an annual rate of return of 8% with continuous compounding.

Let t be the time that it will take the initial deposit to triple itself.

Then the future value of $12000 invested with an annual rate of return of 8% with continuous compounding after t years is given by the formula:

A = Pe^{rt}

where,

A is the future value,

P is the principal (initial deposit),

r is the annual interest rate,

t is the time (in years).

In this case,

P = $12000,

r = 0.08 (8%),

A = $36000 (triple the initial deposit).

Therefore, we have: $36000 = $12000e^ {0.08t}

Dividing both sides by $12000 and taking the natural logarithm of both sides gives:

ln (3) = 0.08t

Solving for t, we get:

t = ln (3) / 0.08 ≈ 12.25 years

Therefore, it will take approximately 12.25 years for the initial deposit of $12000 to triple itself with an annual rate of return of 8% with continuous compounding.

The Reimann sum with n rectangle will be given as \(\sum^{n-1}_{i = 0} f{(x_i)} \Delta x\)

Let us suppose that f is a non-negative function, defined over a closed interval represented by [a, b].

The integral of f with respect to x signifies the area between the graph of f and X-axis. This area would be called definite integral of a function f from a to b. Then Riemannian method of determining this area is:

“if the area is divided into n rectangles of very small breadth, then it would be simpler to calculate the area of such rectangles and then we can add them up

(i ) The width of each rectangle will be denoted as Δx

Δx = b-a/n,

where , a is lower bound

b is upper bound of the integral

(ii) The right-hand endpoints of each rectangle are refer as \(x_i\) and we can find the right endpoints by \(x_i\) = a + Δx.i

(iii) The height of each rectangle is the value of the function at the upper point of the interval.

a + (b-a)/n for the first rectangle , a + 2(b-a)/n for the second rectangle and so on

(iv) The area of the each rectangle will be

Area = Width × height

=> A = (b-a)/2 × a + i(b-a)/2
