The problem of choosing 4 people at random from a group of 10 people is an example of a combination.

Rationale:

In a combination, the order of the selected objects does not matter. The focus is on selecting a group of objects without considering their arrangement. In this problem, the order in which the 4 people are chosen does not affect the outcome. The important aspect is selecting a group of 4 people from the total pool of 10 people. The problem is asking for the number of ways this selection can be done, which aligns with the definition of a combination.

Pythagoras was an ancient Greek mathematician who founded the Pythagorean school of thought. The Pythagorean theorem is a fundamental concept in mathematics that is attributed to Pythagoras and his followers.

It states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. While this theorem is considered a cornerstone of mathematics today, it is important to understand that Pythagoras did not have access to the advanced mathematical tools and methods that we have today.

He had to rely on geometric constructions and reasoning to prove his theorem. Furthermore, Pythagoras believed that all numbers could be expressed as ratios of whole numbers, which is not always true in reality. Despite these limitations, the Pythagorean theorem has stood the test of time and continues to be a crucial tool in mathematics and other fields.

The probability that Sam is late to his final exam is 0.000008, or 0.0008%.

Let A be the event that the first alarm clock works, B be the event that the second alarm clock works, and C be the event that the third alarm clock works. Then, the probability that Sam is late to his final exam is given by:

P(Sam is late) = P(not A) * P(not B) * P(not C)

Since the alarm clocks work independently of each other, the probability that any one of them does not work is 1 - 0.98 = 0.02. Therefore:

P(Sam is late) = 0.02 x 0.02 x 0.02

P(Sam is late) = 0.000008

So, the probability that Sam is late to his final exam is 0.000008, or 0.0008% (rounded to three decimal places). This is a very small probability, indicating that it is highly unlikely that Sam will be late to his final exam if all three alarm clocks are working.

Actually, 0 degrees is not a counterexample for the expression sin(y)*tan(y) = cos(y).

To see why, let's substitute y = 0 degrees into the expression:

sin(y)*tan(y) = cos(y)

sin(0)*tan(0) = cos(0)

0*tan(0) = 1

0 = 1

As we can see, the equation does not hold for y = 0 degrees. However, this does not make 0 degrees a counterexample, because 0 degrees is not in the domain of the tangent function.

The tangent function is undefined at odd multiples of 90 degrees (e.g. 90, 270, etc.), because at those angles the denominator of the tangent function becomes zero. Therefore, we cannot substitute y = 0 degrees into the expression sin(y)*tan(y) = cos(y), because it would result in division by zero.

In summary, 0 degrees is not a counterexample for the expression sin(y)*tan(y) = cos(y), because it is not in the domain of the tangent function.

The median is a better measure of central tendency. It represents the middle value in the dataset and is not affected by extreme values like the mean is.

Mean price = (420000 + 485000 + 379000 + 295000 + 1750000 + 515500 + 315500 + 408000 + 368000 + 315000) / 10 = $537,750

The median is the middle value, which in this case is $397,000 (the average of the two middle values: $379,000 and $408,000).

Comparing the mean and median prices, we see that the mean is higher than the median. However, the median is not affected by outliers like this, so it gives a better representation of the typical price of a property in this dataset.

For any given event, the sum of probability of that event and the probability of its complement must equal one.

The complement of an event is the set of all outcomes in the sample space that are not in the event. The probability of the complement of an event is the probability that the event does not occur.

Therefore, if P(A) is the probability of an event A, then P(A') is the probability of the complement of A, and we have: P(A) + P(A') = 1

This is known as the complement rule of probability and is a fundamental principle in probability theory. It states that the sum of the probabilities of an event and its complement must equal one, which reflects the fact that either the event occurs or its complement occurs, but not both.

The statement is true for any sets A and B.

The statement "A = A - B" is true if and only if every element of A is not an element of B.

The set A - B represents the elements that are in A but not in B. Therefore, A = A - B means that A contains no elements that are in B. In other words, A and B have no elements in common. This is equivalent to saying that every element of A is not an element of B.

Now, since A and B have no elements in common, it follows that B is a subset of A (i.e., B ⊂ A). This is because if an element is in B, it cannot be in A (as A contains no elements of B), and if an element is not in B, it must be in A. Similarly, since A contains no elements of B, it follows that 0 ≤ B ⊆ A. Moreover, since every element of A is not an element of B, it follows that 0 ≤ A ⊆ Bᶜ (the complement of B). Finally, since every set is a subset of itself, it follows that 0 ≤ ⊆ A.

The elephant can travel at a constant speed of 25 mph, while I can travel at a constant speed of 60 miles in 1/2 hour.

It's important to note that miles per hour (mph) is a unit of speed that measures how many miles an object can travel in one hour. In this scenario, the elephant can travel at a constant speed of 25 mph, meaning it can travel 25 miles in one hour. On the other hand, I can travel at a constant speed of 60 miles in 1/2 hour, which means I can travel 120 miles in one hour (since 1/2 hour is equal to 0.5 hours). Therefore, in terms of speed, I am faster than the elephant. However, it's important to keep in mind that speed isn't always the most important factor when it comes to transportation, as other variables such as distance, terrain, and mode of transportation can also play a role.

The number of regions created when constructing a Venn diagram with three overlapping sets is 8.

In a Venn diagram, each set is represented by a circle, and the overlapping regions represent the elements that belong to multiple sets.

When three sets overlap, there are different combinations of elements that can be present in each region.

For three sets, the number of regions can be calculated using the formula:

Number of Regions = 2^(Number of Sets)

In this case, since we have three sets, the formula becomes:

Number of Regions = 2^3 = 8

So, when constructing a Venn diagram with three overlapping sets, there will be a total of 8 regions formed.

Each region represents a unique combination of elements belonging to different sets.

These regions help visualize the relationships and intersections between the sets, providing a graphical representation of set theory concepts and aiding in analyzing data that falls into multiple categories.

Answer:

The finance charge can be calculated by adding up all the monthly payments and subtracting the original loan amount (in this case, $2,200):

Finance charge = 22 x $114.66 - $2,200

Finance charge = $2,524.52 - $2,200

Finance charge = $324.52

To calculate the amount of principal, we need to subtract the finance charge from the total amount borrowed:

Total amount borrowed = $2,200 + finance charge

Total amount borrowed = $2,200 + $324.52

Total amount borrowed = $2,524.52

Amount of principal = Total amount borrowed - Finance charge

Amount of principal = $2,524.52 - $324.52

Amount of principal = $2,200

Therefore, the amount of principal in this loan is $2,200.

Answer:  Therefore, the amount of principal is $1,070.80.

Step-by-step explanation:

To find the amount of principal, we need to first determine the total amount being financed, which is the difference between the purchase cost and the down payment:

Total amount financed = Purchase cost - Down payment

Total amount financed = $5,200 - $2,200

Total amount financed = $3,000

Next, we can use the formula for the present value of an annuity to calculate the amount of principal:

Present value of an annuity = Payment amount x (1 - (1 + interest rate)^(-number of payments))) / interest rate

Plugging in the given values, we get:

$114.66 = Payment amount

16% / 12 = 0.013333... = Interest rate per month

22 = Number of payments

Present value of an annuity = $114.66 x (1 - (1 + 0.013333...)^(-22)) / 0.013333...

Present value of an annuity = $2,004.20

Finally, we can subtract the finance charge from the present value of the annuity to get the amount of principal:

Amount of principal = Present value of annuity - Finance charge

Amount of principal = $2,004.20 - ($114.66 x 22)

Amount of principal = $2,004.20 - $2,522.52

Amount of principal = -$518.32

We get a negative value because the finance charge is greater than the present value of the annuity. Therefore, we need to adjust our calculation of the present value of the annuity.

If we assume that the finance charge is included in the total amount being financed, we can recalculate the present value of the annuity using a total amount financed of $3,518.32:

Present value of an annuity = $114.66 x (1 - (1 + 0.013333...)^(-22)) / 0.013333...

Present value of an annuity = $2,447.52

Then, we can subtract the finance charge from the total amount being financed to get the amount of principal:

Amount of principal = Total amount financed - Finance charge

Amount of principal = $3,518.32 - $2,447.52

Amount of principal = $1,070.80

The value of x is 4cm and the breadth of the rectangle is 11cm and the side of the square is 9cm.

Let's begin by using the formula for the perimeter of a rectangle:

Perimeter of a rectangle = 2 * (length + breadth)

For the rectangle given in the problem, the length is 7 cm and the breadth is x+7 cm. Therefore, the perimeter of the rectangle can be expressed as:

2 * (7 cm + (x+7) cm) = 2 * (x+14) cm = 2x + 28 cm

For the square, the side length is x+5 cm. Therefore, the perimeter of the square can be expressed as:

4 * (x+5) cm = 4x + 20 cm

We are given that the perimeter of both shapes is the same. Therefore:

2x + 28 cm = 4x + 20 cm

Simplifying the equation by subtracting 2x from both sides, we get:

28 cm = 2x + 20 cm

Subtracting 20 cm from both sides, we get:

8 cm = 2x
