The sum of the percentage of students who are either female or have green eyes and the percentage of males who do not have green eyes is approximately 99.7%.

Percentage of Females: (1918 / (1918 + 516 + 27)) * 100 = (1918 / 2461) * 100 ≈ 78.0%

Percentage of Students with Green Eyes: ((516 + 3) / (1918 + 516 + 27)) * 100 = (519 / 2461) * 100 ≈ 21.1%

Percentage of Students who are either Female or have Green Eyes: 78.0% + 21.1% ≈ 99.1%

Therefore, approximately 99.1% of students in the survey are either female or have green eyes.

Percentage of Males with Green Eyes: (516 / (516 + 3)) * 100 = (516 / 519) * 100 ≈ 99.4%

Percentage of Males who do not have Green Eyes: 100% - 99.4% ≈ 0.6%

Therefore, approximately 0.6% of students in the survey are males who do not have green eyes.

To find the sum of these two percentages:

Sum of Percentages: 99.1% + 0.6% ≈ 99.7%

Therefore, the sum of the percentage of students who are either female or have green eyes and the percentage of males who do not have green eyes is approximately 99.7%.

In mathematics, an inductive set is a collection of elements that satisfies certain properties based on the principle of mathematical induction.

It is a fundamental concept in set theory and mathematical reasoning.

The principle of mathematical induction states that if we have a property or statement that holds for a base case (usually the smallest element or a specific starting point) and if we can prove that whenever the property holds for a particular element, it also holds for the next element, then the property holds for all elements in the set.

Answer:

0.30

Step-by-step explanation:

To find the probability that a randomly selected individual would spend between 30 and 40 minutes on the treadmill, we need to calculate the z-scores corresponding to these values and then use the z-table or a statistical calculator to find the probability.

First, we calculate the z-scores using the formula:

z = (x - μ) / σ

where x is the value (in this case, 30 and 40), μ is the mean (42.5), and σ is the standard deviation (4.8).

For x = 30:

z = (30 - 42.5) / 4.8 ≈ -2.604

For x = 40:

z = (40 - 42.5) / 4.8 ≈ -0.521

Next, we look up the probabilities associated with these z-scores in the z-table or use a statistical calculator.

From the z-table or calculator, the probability corresponding to z = -2.604 is approximately 0.0047, and the probability corresponding to z = -0.521 is approximately 0.3015.

To find the probability between 30 and 40 minutes, we subtract the probability associated with z = -2.604 from the probability associated with z = -0.521:

P(30 ≤ x ≤ 40) = P(z = -0.521) - P(z = -2.604)

≈ 0.3015 - 0.0047

≈ 0.2968

Therefore, the probability that a randomly selected individual would spend between 30 and 40 minutes on the treadmill is approximately 0.2968, which is equivalent to 29.68%. Rounding up we will get 0.30.

One main disadvantage of piece rate or commission pay is low quality.

Piece rate or commision pay involves paying workers based on coverage or performance. This way the company is able to cut short excess salary especially for low performing workers.

However, a notable disadvantage of piece-rate pay is that it can lead to employees sacrificing quality for quantity. When employees are paid based on the number of units they produce, they may be tempted to produce low-quality products in order to meet their quotas. This can damage the company's reputation and lead to customer dissatisfaction.

Therefore, piece rate pay will often lead to quality reduction.

As per the given triangle, the base of the triangle, b, is 360 millimeters.

We may use the formula for the area of a triangle to determine the triangle's base, or b, given its 360 square millimetres in area, 41 mm for each side, and 40 millimetres in height.

The formula for calculating a triangle's area is:

Area = (base * height) / 2

Given that,

Area = 360 square millimetres

Height = 40 mm

Sides = 41 mm

So, 360 = (b * 40) / 2

720 = b * 2

b = 720 / 2

b = 360

Thus, the base of the triangle is 360 mm.

Manuel received $187.50, and George received $562.50 for the job.

Let's break down the information provided:

The job paid a total of $750.

George received $3 for every $2 that Manuel received.

To determine the amounts George and Manuel received, we can set up a ratio based on their earnings.

Let's assume Manuel's earnings as the base amount:

George's earnings : Manuel's earnings = $3 : $2

We can set up the following equation to solve for Manuel's earnings:

(Manuel's earnings / Manuel's earnings) = ($2 / $2)

Since the ratio is equivalent, we can say:

George's earnings / Manuel's earnings = $3 / $2

To find the amount each person received, we'll assign a variable to Manuel's earnings. Let's call it "x."

Therefore, George's earnings can be represented as "3x."

According to the given information, their total earnings should sum up to $750:

x + 3x = $750

Combining like terms, we have:

4x = $750

To solve for x, we divide both sides by 4:

x = $750 / 4

x = $187.50

Now, we can determine the amounts each person received:

Manuel's earnings = x = $187.50

George's earnings = 3x = 3 * $187.50 = $562.50

Therefore, Manuel received $187.50, and George received $562.50 for the job.

Step-by-step explanation:

We can begin by using the fact that the selling price was 117.81, including a sales tax of 5%. Let x be the original price of the lawnmower.

After the discount of 32%, the selling price is:

0.68x + 0.05(0.68x) = 117.81

Simplifying and solving for x, we get:

0.68x + 0.034x = 117.81

0.714x = 117.81

x = 165

Therefore, the original price of the lawnmower was $165.

Step-by-step explanation:

The solution to the problem at hand i.e. to draw a horizontal line segment, OM, of any length, the longer the better using ruler, protractor, compass and coloured pencils

are as follows:

Step 1: Take a ruler and align it with a sheet of paper and draw a line. This line can be of any length, although longer lines are preferred.

Step 2: The line is now OM; we must now label its endpoints. Label the leftmost point O, and the rightmost point M.

Step 3: The coloured pencils are used to add decorations to the line. To add decorations, use coloured pencils to make patterns and stripes along the length of the line. This is entirely optional and based on personal preference.

Step 4: To ensure that the line is perfectly horizontal, the protractor should be used. Place the protractor on the line and make sure the zero-degree angle is at O. The line will be horizontal if it is parallel to the baseline of the paper.

Step 5: Using a compass, measure the length of OM to ensure that it is of the desired length.

Answer:Peggy will spend approximately $363.52 constructing the pond and patio in her backyard. The correct answer is not provided among the options given (A, B, C).

Step-by-step explanation:

To calculate the cost of constructing the pond and patio in Peggy's backyard, we need to determine the areas of the pond and patio and then multiply them by their respective costs per square foot.

From the given scale, we can convert the dimensions of the pond and patio from centimeters to feet. According to the scale, 1 cm represents 5 ft.

Patio dimensions:

Width: 2 cm (2 cm * 5 ft/cm = 10 ft)

Length: 2 cm (2 cm * 5 ft/cm = 10 ft)

Area of patio = Width * Length = 10 ft * 10 ft = 100 ft²

Pond dimensions:

Width: 4 cm (4 cm * 5 ft/cm = 20 ft)

Length: 4 cm (4 cm * 5 ft/cm = 20 ft)

Area of pond = π * (Width/2)² = π * (20 ft/2)² = π * 10 ft² ≈ 31.42 ft²

Cost calculation:

Cost of pond = Area of pond * Cost per square foot = 31.42 ft² * $6/ft² = $188.52

Cost of patio = Area of patio * Cost per square foot = 100 ft² * $1.75/ft² = $175.00

Total cost = Cost of pond + Cost of patio = $188.52 + $175.00 = $363.52
