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

Lin says that 4÷3/4 equals 5 1/4 because there are five groups of 3/4 and 1/4 left. Do you agree with Lin?
The result is 5 1/3, not 5 1/4 as Lin suggested.
No, I don't agree with Lin's statement. Lin's explanation is incorrect.
When evaluating the expression 4 ÷ (3/4), we need to remember the order of operations, which states that we should perform the division before the multiplication.
To divide by a fraction, we can multiply by its reciprocal. The reciprocal of 3/4 is 4/3. Therefore:
4 ÷ (3/4) = 4 * (4/3)
Now we can simplify the expression:
4 * (4/3) = (4 * 4) / 3 = 16 / 3
The result, 16/3, is an improper fraction. To convert it to a mixed number (a whole number and a fraction), we divide the numerator (16) by the denominator (3):
16 ÷ 3 = 5 with a remainder of 1
The quotient is 5, and the remainder is 1. Therefore, the result is 5 1/3, not 5 1/4 as Lin suggested.

i’ve been struggling for hours and i still can’t get it!! someone please help
Answer:
40.1 cm
Step-by-step explanation:
For this problem we will use trigonometry. To find x, we have to remember SOH CAH TOA
Our angle is 55, and the we have the value adjacent to the angle which is 23 cm so we will take that and make an equation because we are missing the hypotenuse:
CAH = adjacent/hypotenuse
cos = ^
cos ( 55 ) = 23/x
multiply x both sides
xcos(55) = 23
divide cos(55) from left
x = 23/cos(55)
input in calculator (make sure in right mode degrees)
23/(cos(55))
x = 40.09927 cm
x = 40.1 cm

The Pound to Australian Dollar (GBP/AUD) exchange rate has been going up besides the drop in UK business optimism. The CBI business optimism index dropped from 0 to -22 in the first quarter, which shows the negative impact of the recent lockdown. However, this had been changed by the idea of greater US fiscal stimulus measures and the global economic outlook improving. On the other hand, the Australian Dollar (AUD) struggled to find support despite the December unemployment rate decreasing from 6.8% to 6.6%. This shows that the labor market remains elevated by previous trends, weighing on AUD exchange rates. The retail sales trends for December is expected to show a -2.5% monthly contraction, signaling a continued impact of Covid-19. The UK PMIs could also have an impact on the GBP/AUD exchange rate, with signs of the UK economy likely to limit any potential gains.
The correct answer is interval 2. A function is a rule that relates each element in one set, called the domain, to exactly one element in another set, called the range.
What is function?It is a mathematical expression that takes an input, performs a calculation and produces an output.
In order to determine if dy/dx>0 and d2y/dx2<0 over interval 2, we must take the first and second derivatives of the function y=f(x). The first derivative of the function is dy/dx=2x-3 and the second derivative of the function is d2y/dx2=2.
Now, if we look at the graph, we can see that the function is increasing from 0 to 3 and then decreasing from 3 to 6. This means that over interval 2, which is from 3 to 6, the first derivative, dy/dx, must be negative. This means that dy/dx<0 over interval 2.
Furthermore, the second derivative, d2y/dx2, must be negative over interval 2 since the graph is decreasing over this interval. This means that d2y/dx2<0 over interval 2.
Therefore, the correct answer is interval 2 since it is the only interval for which both dy/dx>0 and d2y/dx2<0 are true.

What is angle?Angle is a two-dimensional figure that is formed by two straight lines intersecting each other. It can also be defined as the amount of rotation between two lines or planes. An angle is measured in degrees, with a full rotation being 360°.
The given triangle is a right-angled triangle as it has an angle of 64° which is a right angle. The angle 35° and 113 are the other two angles of the triangle. To find the length of the side 'х', we need to use the Pythagorean Theorem. The Pythagorean Theorem states that "the square of the hypotenuse is equal to the sum of the squares of the other two sides".
In this case, the hypotenuse is 113, and the other two sides are 'х' and the perpendicular side opposite to the angle of 35°. Therefore, using the Pythagorean Theorem, we can say:
113² = х² + (perpendicular side)²
Using the trigonometric ratio sine, we can calculate the length of the perpendicular side opposite to the angle 35°, which is equal to the sine of 35° multiplied by the hypotenuse.
(perpendicular side) = sin 35° × 113
Therefore, the equation for the triangle now becomes:
113² = х² + (sin 35° × 113)²
Simplifying the equation and solving for 'х' gives us:
х² = 113² - (sin 35° × 113)²
х = √(113² - (sin 35° × 113)²)
Finally, substituting the values, we get:
х = √(113² - (sin 35° ×113)²)
= √(12,841 - (0.5736 × 113)²)
= √(12,841 - 6,539.7808)
= √6,301.2192
= 79.20
Therefore, the length of the side 'х' is 79.20 units to two decimal places.

What is percent?Percent is a term used to describe a fraction or ratio that represents a portion of 100. It is often represented by the symbol % and is commonly used to express a portion or a rate of change. For example, if an item is discounted by 20%, it means the price has been reduced by 20% of the original price or 20/100 of the original price. Similarly, if someone earns a grade of 85% on a test, it means they answered correctly 85 out of 100 questions.
Here,
7. To find the time (in years) in which a loan of N3,900 at the rate of 5% yields N585.60 in simple interest, we can use the formula:
I = P * r * t
where I is the interest, P is the principal, r is the interest rate, and t is the time in years.
Substituting the given values, we get:
585.60 = 3,900 * 0.05 * t
Solving for t, we get:
t = 3 years
Therefore, it will take 3 years for the loan of N3,900 at the rate of 5% to yield N585.60 in simple interest.
8. To find the time (in years) for a loan of N20,000 at the rate of 7% to accumulate N70,000 in simple interest, we can use the formula:
I = P * r * t
where I is the interest, P is the principal, r is the interest rate, and t is the time in years.
Substituting the given values, we get:
70,000 = 20,000 * 0.07 * t
Solving for t, we get:
t = 50 years
Therefore, it will take 50 years for the loan of N20,000 at the rate of 7% to accumulate N70,000 in simple interest.
9. To find the time (in years) for N300 to accumulate to N390 at the rate of 3%, we can use the formula:
I = P * r *t
where I is the interest, P is the principal, r is the interest rate, and t is the time in years.
Substituting the given values, we get:
90 = 300 * 0.03 * t
Solving for t, we get:
t = 10 years
Therefore, it will take 10 years for N300 to accumulate to N390 at the rate of 3%.
10. To find the year in which N5,100 will yield an interest of N170 at the rate of 2.5% per annum, we can use the formula:
I = P * r * t
where I is the interest, P is the principal, r is the interest rate, and t is the time in years.
Substituting the given values, we get:
170 = 5,100 * 0.025 * t
Solving for t, we get:
t = 2 years
Therefore, it will take 2 years for N5,100 to yield an interest of N170 at the rate of 2.5% per annum. If the interest is compounded, we would need to use the compound interest formula instead.
11. To find the rate per annum at which N4,600 will yield an interest of N230 for 2 years, we can use the formula:
I = P * r * t
where I is the interest, P is the principal, r is the interest rate, and t is the time in years.
Substituting the given values, we get:
230 = 4,600 * r * 2
Solving for r, we get:

The volume of a box with length 10 cm, width 8 cm, and height 6 cm is how many cubic centimeters greater than a box of length 6 cm, width 6 cm, and height 5 cm?
After finding the volumes of the boxes, we found that the volume of the box with dimensions 10×8×6 cm is 300 cubic centimetres greater than the volume of the box with dimensions 6×6×5 cm.
What is meant by the volume?
Three-dimensional space is quantified by volume. Any three-dimensional solid's volume is just the amount of space it takes up. A cube, cuboid, cone, cylinder, or sphere can be one of these solids. Volumes vary depending on the shape. A solid's volume is expressed in cubic units. Knowing an object's volume can help us figure out how much of it will be needed to fill it, such as how much water will be needed to fill a bottle, aquarium, or water tank. The object's capacity is another name for it.
First box dimensions
Length l = 10 cm
Width w = 8 cm
Height h = 6 cm
The volume of box = l * w * h = 10 * 8 * 6 = 480 cm³
Second box dimensions
Length l = 6 cm
Width w = 6cm
Height h = 5 cm
The volume of box = l * w * h = 6 * 6 * 5 = 180 cm³
The difference between volumes of boxes = 480 - 180 = 300cm³
Therefore after finding the volumes of the boxes, we found that the volume of the box with dimensions 10×8×6 cm is 300 cubic centimetres greater than the volume of the box with dimensions 6×6×5 cm.

Laars earns an annual salary of $90,000. Determine his gross earnings per pay period under each of the following payment frequencies: a. Monthly b. Semi-monthly c. Biweekly d. Weekly
Answer:
To determine Laars' gross earnings per pay period under different payment frequencies, we need to divide his annual salary of $90,000 by the number of pay periods in a year for each frequency.
a. Monthly: Laars will receive 12 paychecks per year, one per month.
Gross earnings per pay period = $90,000 / 12 = $7,500 per month
b. Semi-monthly: Laars will receive 24 paychecks per year, two per month.
Gross earnings per pay period = $90,000 / 24 = $3,750 per semi-monthly period (twice per month)
c. Biweekly: Laars will receive 26 paychecks per year, one every two weeks.
Gross earnings per pay period = $90,000 / 26 = $3,461.54 per biweekly period (every two weeks)
d. Weekly: Laars will receive 52 paychecks per year, one per week.
Gross earnings per pay period = $90,000 / 52 = $1,730.77 per weekly period (every week)
Therefore, Laars' gross earnings per pay period are $7,500 per month, $3,750 per semi-monthly period, $3,461.54 per biweekly period, and $1,730.77 per weekly period.
