Answer: To subtract mixed numbers with different denominators, we need to convert them into like fractions first.

14 1/3 can be converted to an improper fraction as follows:

14 1/3 = (14 x 3 + 1) / 3 = 43/3

6 5/8 can be converted to an improper fraction as follows:

6 5/8 = (6 x 8 + 5) / 8 = 53/8

Now we can subtract the fractions:

43/3 - 53/8

To get a common denominator, we can multiply the denominators together: 3 x 8 = 24

43/3 x 8/8 = 344/24

53/8 x 3/3 = 159/24

Now we can subtract the numerators:

344/24 - 159/24 = 185/24

Therefore, 14 1/3 - 6 5/8 = 185/24 or 7 13/24 as a mixed number in simplest form.

Step-by-step explanation:

The simplified value of 14 1/3- 6 5/8 is 7 17/24.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

To subtract 6 5/8 from 14 1/3, we need to have the same denominator.

Converting the mixed numbers to improper fractions, we get:

14 1/3 = 43/3

6 5/8 = 53/8

Now, we need to find a common denominator, which is 24.

Multiplying the numerator and denominator of 43/3 by 8 and 53/8 by 3, we get:

43/3 * 8/8 = 344/24

53/8 * 3/3 = 159/24

Now, we can subtract:

43/3 - 53/8 = (344/24) - (159/24) = 185/24

Therefore, 14 1/3 - 6 5/8 = 185/24 or 7 17/24 as a mixed number.

The value of cos(2x+y) is -12/65.

Cosine, commonly denoted as cos, is a mathematical function that relates the angle of a right triangle to the ratio of the adjacent side to the hypotenuse. In other words, it is the ratio of the length of the adjacent side of an angle to the hypotenuse of the right triangle containing that angle. Cosine is one of the basic trigonometric functions, along with sine and tangent, and is widely used in mathematics, physics, and engineering to model various phenomena.

Cosine is periodic with a period of 2π, and its values range from -1 to 1. When the angle is 0°, the cosine is equal to 1, indicating that the adjacent side of the triangle is equal to the hypotenuse.

We can use the trigonometric identities for cosine to find cos(2x+y), using the values of x and y given:

cos(2x+y) = cos(2x)cos(y) - sin(2x)sin(y)

To find cos(2x), we can use the double angle identity for cosine:

cos(2x) = cos²(x) - sin²(x)

To find cos(x) and sin(x), we can use the fact that x = sin⁻¹(4/5) and the Pythagorean theorem:

sin(x) = 4/5

cos(x) = √(1 - sin²(x)) = √(1 - 16/25) = 3/5

Substituting these values into the double angle identity, we get:

cos(2x) = cos²(x) - sin²(x) = (3/5)² - (4/5)² = -7/25

To find sin(2x), we can use the double angle identity for sine:

sin(2x) = 2sin(x)cos(x) = 2(4/5)(3/5) = 24/25

To find cos(y) and sin(y), we can use the fact that y = tan⁻¹(12/5) and the Pythagorean theorem:

sin(y) = 12/13

cos(y) = 5/13

Substituting these values into the expression for cos(2x+y), we get:

cos(2x+y) = cos(2x)cos(y) - sin(2x)sin(y)

= (-7/25)(5/13) - (24/25)(12/13)

= -60/325

= -12/65

Therefore, cos(2x+y) = -12/65.

Answer:

First, let's find the fraction of people wearing green or red shorts:

1/4 + 1/6 = 3/12 + 2/12 = 5/12

This means that 5/12 of the people are wearing either green or red shorts. To find the fraction of people wearing blue shorts, we need to subtract this from 1 (since the three options are exhaustive):

1 - 5/12 = 7/12

So, 7/12 of the people are wearing blue shorts. To find out how many people this represents, we can multiply this fraction by the total number of people in the race:

7/12 x 24 = 14

Therefore, 14 people are wearing blue shorts.

Step-by-step explanation:

Answer:

To use a tape diagram, we can start by drawing a rectangle to represent the total number of people in the race. Then, we can divide it into four equal parts to represent the people wearing green shorts and into six equal parts to represent the people wearing red shorts.

Let's use the letter "B" to represent the number of people wearing blue shorts. We know that the total number of people is 24, so we can write:

4 parts + 6 parts + B parts = 24

Simplifying this equation, we get:

10 + B = 24

Subtracting 10 from both sides, we get:

B = 14

Therefore, 14 people are wearing blue shorts.

To double-check our answer, we can add up the number of people in each category:

4 parts out of 24 = 6 people wearing green shorts

6 parts out of 24 = 4 people wearing red shorts

B parts out of 24 = 14 people wearing blue shorts

6 + 4 + 14 = 24, which matches the total number of people in the race.

Answer:

Let's assume Adrian worked for x hours. Then, Bryan worked for (x + 8) hours.

According to the problem, the total hours worked by both is 88, so we can set up the equation:

x + (x + 8) = 88

Simplifying the equation:

2x + 8 = 88

Subtracting 8 from both sides:

2x = 80

Dividing both sides by 2:

x = 40

So Adrian worked for 40 hours and Bryan worked for 48 hours (since Bryan worked 8 hours more than Adrian).

Answer:

Adrian: 40 hours

Bryan: 48 hours

Answer: To find (g∘f)(x), we need to first find the composite function g(f(x)):

g(f(x)) = g(2x - 2)

We can now substitute the expression for f(x) into g(x):

g(f(x)) = g(2x - 2) = 6(2x - 2)^2 - 3

Expanding the squared term, we get:

g(f(x)) = 6(4x^2 - 8x + 4) - 3

Therefore , the solution of the given problem of speed comes out to be it will take 4 hours to travel the same distance at an average speed of 90 km/h.

We can determine something's speed by keeping a watch on it from a distance. The amount of distance an object can move in a specific amount of time depends on its speed. Velocity is calculated using the formula velocity = distance/time. The three most popular pace measurements are miles per hour (mile), kilometres per hour (kilometres), and metres for each second (m/s) (mph).

Here,

Applying the algorithm

Distance is determined by multiplying time and motion.

We can make the two equations equal because we know that the distance travelled in both scenarios is the same:

Distance = time + speed1

1 = time2 + speed2

where time1 is the first time (3 hours), speed1 is the first average speed (120 km/h), speed2 is the second average speed (90 km/h), and we're trying to determine time2.

Inputting the numbers provided yields:

Distance: 360 km at 120 km/h for three hours.

We can now determine the time2:

360 kilometres are equal to 90 kilometres per hour multiplied by two.

time2 = 360 km x 90 km/hr = 4 hours

Therefore, it will take 4 hours to travel the same distance at an average speed of 90 km/h.

The answer of the given question based on the constant of proportionality the answer is  constant of proportionality equal to 1.

Slope is  measure of  steepness of a line. It describes how much  vertical coordinate (y) changes for given change in  horizontal coordinate (x). In other words, it is  rate at which  line rises or falls as you move horizontally along it

To find the constant of proportionality between y and x, we need to calculate the slope of this line.

We can choose any two points on the line and use them to calculate the slope. Let's choose the points (2, 2) and (8, 8), which are the first and last points on the line. The slope of the line passing through these points is:

slope = (change in y)/(change in x) = (8 - 2)/(8 - 2) = 1

This means that for every increase of 1 in the x-coordinate, there is a corresponding increase of 1 in the y-coordinate. Therefore, the constant of proportionality between y and x is 1. We can write this as:

y = x

This means that y is directly proportional to x with a constant of proportionality equal to 1.

The probability that this person also sailed is 1.

What is probability?

In mathematics, probability is a measure of the likelihood or chance that an event will occur. It is typically expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

Out of 50 people, 40 took part in walking and 18 took part in sailing. However, 3 people did neither activity, which means that 40 + 18 - 3 = 55 people took part in at least one of the activities.

Let's represent the set of people who walked as A, and the set of people who sailed as B. We want to find the probability that a randomly chosen person from A is also in B, which can be represented as P(B|A).

Using the formula for conditional probability, we have:

P(B|A) = P(A and B) / P(A)

We know that P(A and B), the probability that a person took part in both walking and sailing, is 50 - 3 = 47 (since 3 people did neither activity). We also know that P(A), the probability that a person took part in walking, is 40.

Therefore,

P(B|A) = 47 / 40

which simplifies to

P(B|A) = 1.175

probabilities cannot be greater than 1, so the actual probability is 1, meaning that it is certain that a person who walked also sailed.

Look at the left triangle.

Imagine that the 8 m segment continues to the bottom, and you have a horizontal leg there.

The hypotenuse measures 15 m.

The vertical leg is 8 m + 4 m = 12 m.

a² + b² = c²

12² + b² = 225

b = 9

The horizontal leg is 12 m.

A = 2 × 12 m × 9 m / 2 - 4 m × 4 m

A = 92 m²

Bottom rectangle: length = 20 cm; width = 7 cm

Upper trapezoid: bottom base = 20 cm - 13 cm = 7 cm; height = 15 cm - 7 cm = 8 cm; upper base = 4 cm

A = 20 cm × 7 cm + (1/2)(7 cm + 4 cm)(8 cm)

A = 184 cm²

The company's advanced degree holders make up 18% of the workforce.

A percentage, which is denoted by the number 100, is a proportion, fraction, or piece of a whole. The Roman phrase per centum, which meaning "by the 100" or "per one hundred," is where the term "percent" originates. A numerical value and the percentage symbol (%) can be used to express percentages.

Part A:

The following expression sums up the amount of company employees with advanced degrees:

0.40c(0.15) + 0.60c(0.20)

Explanation: First, we multiply the overall amount of workers (c) by the proportions of male and female employees, which are, respectively, 40% and 60%. The number of male workers (0.40c) is then multiplied by the percentage of men who have advanced degrees (15%), and the number for female employees (0.60c) is multiplied by the percentage of women who have advanced degrees (20%). In order to calculate the overall number of workers with advanced degrees, we must add these two numbers.

If we condense this phrase, we get:

0.06c + 0.12c = 0.18c

Part B:

The number of staff members with advanced degrees must be divided by the total amount of employees, and the result must be multiplied by 100% to determine the percentage of the business that holds advanced degrees:

(0.18c/c) × 100% = 18%

The normal distribution has a bell-shaped curve, with the highest point at the mean and a gradual decrease in frequency on either side.

What is Normal Distribution ?

A normal distribution is a continuous probability distribution that is often used in statistics to model a wide variety of phenomena, such as measurements of height, weight, or IQ.

The normal distribution is symmetric. This means that the distribution is mirror-image symmetric around its mean, so that the same proportion of values lie on either side of the mean.

The normal distribution is characterized by two parameters: its mean (μ) and standard deviation (σ). The mean is the center of the distribution, while the standard deviation measures the spread of the distribution.

The total area under the normal distribution curve is equal to 1. This means that the probability of any event occurring is between 0 and 1.

The empirical rule, also known as the 68-95-99.7 rule, applies to normal distributions. This rule states that approximately 68% of the data will fall within one standard deviation of the mean, approximately 95% of the data will fall within two standard deviations of the mean, and approximately 99.7% of the data will fall within three standard deviations of the mean.

Answer:

4 units

Step-by-step explanation:

Since the x-value is the same in both ordered pairs, you can just figure out the y-step ([tex]y_{2} -y_{1}[/tex]) and get your distance. -10 - (-6) = -4, so a distance of 4 units (negative sign does not matter in this case).

If both the x-values and y-values were different, another way to solve is to figure out the y- and x-steps and plug them into the Pythagoras theorem [tex]A^2+B^2 = C^2[/tex], with A being the horizontal distance (x-step) and B being the vertical distance (y-step).

You can also find the distance between 2 points by using the distance formula, which is  [tex]d = \sqrt{(x_{2}-x_{1})^{2} - (y_{2}-y_{1})^{2}[/tex]. After inserting the x- and y-coordinates of your ordered pair you get  [tex]d = \sqrt{(3-3)^{2} - (-10-(-6))^{2}[/tex]
Simplifying:
[tex]d = \sqrt{- (-10-(-6))^{2}}[/tex].  [tex](3-3)^{2}[/tex] was eliminated.
Then we distribute the negative signs: [tex]d = \sqrt{- (-10+6)^{2}}[/tex] --> [tex]d = \sqrt{(10-6)^{2}}[/tex].
[tex]d = \sqrt{(4)^{2}}[/tex] --> [tex]d = \sqrt{16}[/tex] --> [tex]d = 4[/tex]
So, the distance between the points is 4 units.
Side note: The distance formula works in the same way as the Pythagoras theorem.
