The mean number of employees who work on a given day is less than the median number of employees who work on a given day and option C is correct.

In statistics, we frequently choose a representative value that roughly describes the full collection to represent a set of data. The label "measure of central tendency" denotes that this representative value is one around which the data is centred. The mean, median, and mode are these central tendencies.

Mean = sum of all values/frequency

Mean = (20(0.01) + (21(0.1)) + (22(0.1)) + (23(0.4)) + (24(0.3))

mean is 22.7.

The median id the value of X for which P(X<x) is greater than or equal to 0.5 and P(X>x) is greater than or equal to 0.5. Therefore, median is 23.

Mode is the value of X having maximum probability. Therefore, mode is 23.

Answer:

Step-by-step explanation:

Since the circle is inscribed in the square, the diameter of the circle is equal to the side length of the square. Therefore, the diagonal of the square is twice the radius of the circle, or 10 mm.

To find the area of the square, we can use the formula A = s^2, where s is the side length of the square. The diagonal of the square is √2 times the side length, so we have:

10 mm = √2 x s

s = 10 mm / √2

The area of the square is:

A = s^2 = (10 mm / √2)^2 = 100 mm^2 / 2 = 50 mm^2

To find the area of the circle, we can use the formula A = πr^2, where r is the radius of the circle. We are given that the radius is 5 mm, so:

A = π(5 mm)^2 = 25π mm^2

To find the shaded section, we need to subtract the area of the circle from the area of the square. The shaded section is the remaining area of the square after the circle has been inscribed. Therefore, the shaded section is:

Shaded Section = Square Area - Circle Area

Shaded Section = 50 mm^2 - 25π mm^2

Shaded Section ≈ 10.79 mm^2 (rounded to two decimal places)

1. After 13 years of investing $9,500 per period at 10% interest, the investment would be worth approximately $281,461.22.

2. After 50 years of investing $9,500 per period at 9% interest, the investment would be worth approximately $5,967,875.20.

To calculate the future value of an investment, we can use the formula for compound interest:

FV = PV x (1 + r)^n

where FV is the future value of the investment, PV is the present value or initial investment, r is the annual interest rate, and n is the number of compounding periods.

For the first investment:

PV = $9,500 per period

r = 10% per year

n = 13 years

Since we're making regular periodic investments, we can use the formula for the future value of an annuity:

FV = PMT x [(1 + r)^n - 1] / r

where PMT is the regular payment or investment per period. Plugging in the numbers, we get:

FV = $9,500 x [(1 + 0.1)^13 - 1] / 0.1 = $281,461.22

So after 13 years of investing $9,500 per period at 10% interest, the investment would be worth approximately $281,461.22.

For the second investment:

PV = $9,500 per period

r = 9% per year

n = 50 years

Using the same formula for the future value of an annuity, we get:

FV = $9,500 x [(1 + 0.09)^50 - 1] / 0.09 = $5,967,875.20

So after 50 years of investing $9,500 per period at 9% interest, the investment would be worth approximately $5,967,875.20.

The exact perimeter of the triangle is 2√5 + √34 + 5√2.

To find the perimeter of the triangle, we need to find the distances between its vertices and add them up. Let's use the distance formula to find the three distances:

Distance between (2, -2) and (-2, 0):
d1 = √[(2 - (-2))^2 + (-2 - 0)^2]

= √[(4)^2 + (-2)^2]

= √(16 + 4)

= √20

= 2√5

Distance between (2, -2) and (-1, -7):

d2 = √[(2 - (-1))^2 + (-2 - (-7))^2]

= √[(3)^2 + (5)^2]

= √(9 + 25)

= √34

Distance between (-2, 0) and (-1, -7):

d3 = √[(-2 - (-1))^2 + (0 - (-7))^2]

= √[(-1)^2 + (7)^2]

= √(1 + 49)

= √50

= 5√2

Now, we can add up the distances to find the perimeter:

perimeter = d1 + d2 + d3

= 2√5 + √34 + 5√2

Therefore, the exact perimeter of the triangle is 2√5 + √34 + 5√2.

The perimeter of a triangle is the total length of its three sides. To find the perimeter, you simply add the lengths of the three sides together.

For example, if a triangle has side lengths of 5 cm, 6 cm, and 7 cm, its perimeter would be:

Step-by-step explanation:

The interest Kay will have to pay can be calculated using the simple interest formula:

interest = principal x rate x time

where the principal is the amount borrowed, the rate is the annual interest rate, and the time is the duration of the loan in years.

In this case, the principal is £5,000, the rate is 15% per year, and the time is 1 year. Substituting these values into the formula, we get:

interest = 5000 x 0.15 x 1 = £750

Therefore, Kay will have to pay £750 in interest over the course of the one-year loan.

Answer:

Step-by-step explanation:

Since the interest rate is 15%, she'll have to pay 15% of the principal per yar, which is £5000 x 15 / 100 = £750. And since she borrows it for only one years, that total amount of interest will be £750 x 1 = £750.

For the given insertion sort program the answer is (E) I, II, and III.

What is insertion sort?

Insertion sort is a simple sorting algorithm that works by repeatedly iterating through the elements of an array, or a list, and inserting each element into its proper position within the sorted portion of the array. The algorithm maintains a sorted sublist of elements, which starts as the first element of the array, and then iterates through the remaining unsorted elements one-by-one, comparing each element with the elements in the sorted sublist and moving them to the right until the correct position is found. In other words, insertion sort iteratively expands the sorted sublist by inserting each new element into its correct position, until the entire array is sorted. The time complexity of the insertion sort algorithm is O(n^2) in the worst-case scenario, where n is the number of elements in the array, but it can perform much better on small datasets or partially sorted arrays.

According to given conditions:

For the first question:

After the first pass of the outer loop, the array will be [2, 5, 4, 1, 3, 6]. After the second pass, the array will be [2, 4, 5, 1, 3, 6]. After the third pass, the array will be [1, 2, 4, 5, 3, 6]. Therefore, the answer is (C) [1, 2, 4, 5, 3, 6].

For the second question:

Statement 1 will execute 6 times because there are 6 elements in the array. Statement 2 will also execute 6 times because each element in the array will be moved to its correct position during the insertion sort. Therefore, the answer is (E) 6, 6.

For the third question:

To correctly separate the words in listofWords with commas and enclose them in braces, we need to iterate through the list and add each word to the result string followed by a comma (except for the last word) and a space. Then we need to remove the last comma and space and add the opening and closing braces. This can be achieved with the following expression and condition:

Expression: listofWords.get(k) + ", "

Condition: k != listofWords.size() - 1

Therefore, the answer is (A) expression: listofWords.get(k) + ", ", condition: k != listofWords.size() - 1.

For the fourth question:

To sort the integers in elements in descending order, we need to make two changes to the sort method:

I. Replace line 9 with: if (elements[k] > elements[index])

II. Replace lines 15-17 with:

Line 15: int temp = elements[index];

Line 16: elements[index] = elements[j];

Line 17: elements[j] = temp;

III. Replace line 3 with: for (int j = elements.length - 1; j > 0; j--) and replace line 7 with: for (int k = 0; k < j; k++)

Therefore, for the given insertion sort program the answer is (E) I, II, and III.

The value of x from the adjoining figure​ given as pentagon is 85°.

An angle is a geometric figure formed by two rays, or lines, that share a common endpoint, called the vertex. The measure of an angle is typically expressed in degrees, radians, or other units of angular measurement, and it represents the amount of rotation between the two rays. Angles are often used in geometry, trigonometry, physics, and other fields to describe the orientation of objects and the relationships between them. Some common types of angles include acute angles (less than 90°), obtuse angles (greater than 90°), and right angles (exactly 90°).

Here,

This is a pentagon with sum of angle as 540 degrees.

50+x=180

x=130°

x+80+120+125+130=540

The surface area of the rectangular prism, found by summing the surface areas of the six rectangular faces is about 2,600 square inches

A rectangular prism is a three dimensional solid with six rectangular faces, such that faces of the prism that face each other are parallel and congruent.

The surface area of the rectangular prism is the sum of the surface areas of the six rectangular faces of the prism

The area of the rectangles that make up the surface are;

A₁ = 8 inches × 36 inches = 288 square inches

A₂ = 23 inches × 8 inches = 184 square inches

A₃ = 23 inches × 36 inches = 828 square inches

A₄ = 23 inches × 8 inches = 184 square inches

A₅ = 8 inches × 36 inches = 288 square inches

A₆ = 23 inches × 36 inches = 828 square inches

The surface area of the rectangular prism, A, is therefore;

A = A₁ + A₂ + A₃ + A₄ + A₅ + A₆

Therefore;

A = 288 + 184 + 828 + 184 + 288 + 828 = 2600

The surface area of the rectangular prism is 2,600 square inches

What is the discounts ?

A discount is a reduction in the price of a product or service. It is often used as an incentive to encourage customers to buy a product or service, especially when the original price is considered too high.

Let's assume the regular price of the suit to be x.

According to the problem, the sale price of the suit after a 25% discount is $187.5.

This can be written as:

x - 0.25x = 187.5

Simplifying the equation:

0.75x = 187.5

Dividing both sides by 0.75:

x = 250

Hence, the regular price of the suit is $250.
