As a result, 0.85 or 85% of vacationers are likely to visit either the Magic Kingdom or Epcot Center.

The measurement and study of random events are the focus of the mathematic branch known as probability. It is a means to express how likely an event or series of events are to occur. Probability is stated as a number between 0 and 1, where 0 denotes the impossibility of an event and 1 denotes its certainty. An occurrence that has a probability of 0.5 (or 50%) is equally likely to occur or not. In a variety of disciplines, including statistics, economics, engineering, and science, probability is used to evaluate and forecast the possibility of specific events in light of the information and presumptions at hand.

given

The formula for the union of two events must be used to determine the likelihood that a visitor will go to either the Magic Kingdom or Epcot Center:

P(A or B) equals P(A) + P(B) - P (A and B)

P(A) represents the likelihood that event A will occur, P(B) represents the likelihood that event B will occur, and P(A and B) represents the likelihood that both events will occur at the same time.

Let's describe event A in this scenario as a trip to the Magic Kingdom, and event B as a trip to the Epcot Center. We are aware of:

P(A) = 0.60 (the Magic Kingdom is visited by 60% of tourists)

P(B) = 0.50 (50 percent of tourists go to the Epcot Center)

P(A and B) = 0.25 (25% of tourists go to both places).

The result of the formula is:

P(A or B) is equal to P(A) + P(B) - P(A and B), which is 0.60 + 0.50 - 0.25 = 0.85.

As a result, 0.85 or 85% of vacationers are likely to visit either the Magic Kingdom or Epcot Center.

Answer:

BE=15

Step-by-step explanation:

Since E is the center, BE=2x+1

And AC is 6x-12 with E being a midpoint.

Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that

you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE

6x-12=4x+2

BD=AC

6x-4x-12=2

2x=2+12

2x=14

x=7

BE= 2x+1

2(7)=14+1=15

The radian measure for 315° is (7/4)π radians.

What exactly is a radian measure?

Radian measure is a unit of measurement for angles, where one radian is defined as the central angle subtended by an arc of a circle with a length equal to the radius of the circle. Therefore, to convert degrees to radians, we need to multiply the degree measure by pi/180.

Now,

To convert 315 degrees to radians, we can use the formula:

radians = degrees x π/180

So, we have:

radians = 315 x π/180

Simplifying this expression, we get:

radians = (7/4) x π

Therefore,

             315 degrees is equal to (7/4) π radians.

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%

Therefore, 18% of the company has advanced degrees.

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

Step-by-step explanation:

The required answers are a) 6.5 m, b) Dimensions 8 m, 5 m c) square has the greater area.

(a) Let s be the length of a side of the square. The perimeter of a square is given by 4s. Since the piece of wire used to make the square has length 26 m, we have:

[tex]$\begin{align*}4s &= 26 \s &= \frac{26}{4} = 6.5 \text{ m}\end{align*}[/tex]

Therefore, the length of a side of the square is 6.5 m.

(b) Let l be the length of the rectangle. Then the width of the rectangle is l-3. The perimeter of a rectangle is given by 2(l+w). Since the piece of wire used to make the rectangle has length 26 m, we have:

[tex]$\begin{align*}2(l + (l-3)) &= 26 \2(2l-3) &= 26 \4l - 6 &= 26 \4l &= 32 \l &= 8 \text{ m}\end{align*}[/tex]

Therefore, the length of the rectangle is 8 m and its width is 8-3=5 m.

(c) The area of the square is given by [tex]$s^2$[/tex], which in this case is [tex]$6.5^2 = 42.25$[/tex] square meters. The area of the rectangle is given by lw, which in this case is [tex]$8\times5 = 40$[/tex] square meters. Therefore, the square has the greater area.

Using the system of equations, we found that the amount to be invested in fund A is $180,000 and in fund B is $320,000.

What is meant by an equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

The amount in the IRA account = $500,000

Let the amount invested in fund A be x and fund B be y.

x + y = 500,000

The amount received annually for fund A = 0.052x

The amount received annually for fund B = 0.077y

This amount is given as:

0.052x + 0.077y = 34,000

Now we have a system of equations.

x + y = 500,000

0.052x + 0.077y = 34,000

Multiply the first equation by 0.052.

0.052x + 0.052y = 26,000

0.052x + 0.077y = 34,000

Subtracting,

-0.025y = -8000

y = 320,000

Then, x = 500,000 - y = 500,000 - 320,000 = 180,000

Therefore using the system of equations, we found that the amount to be invested in fund A is $180,000 and in fund B is $320,000.

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

Simplifying and combining like terms, we get:

g(f(x)) = 24x^2 - 48x + 21

Therefore, (g∘f)(x) = 24x^2 - 48x + 21.

Answer:

Therefore, the depth of Challenger Deep to the nearest fathom is 6,466 fathoms, and it is greater than 7 miles.

Step-by-step explanation:

One fathom is equal to 6 feet. To convert 38,797 ft. to fathoms, we divide by 6:

38,797 ft. / 6 = 6,466.17 fathoms

Rounding this to the nearest fathom gives us 6,466 fathoms.

One mile is equal to 5,280 feet. Seven miles would be:

7 mi. x 5,280 ft/mi = 36,960 ft.

Since 38,797 ft. is greater than 36,960 ft., we can conclude that Challenger Deep's depth is greater than 7 miles.

Therefore, the depth of Challenger Deep to the nearest fathom is 6,466 fathoms, and it is greater than 7 miles.

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.

Step-by-step explanation:

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.
