The measure of the angle can be found by solving the equation

x = 5(180 - x) - 660.

Let's assume the measure of the angle is x. The supplement of the angle is 180 - x since they are supplementary angles.

According to the given information, the measure of the angle is 660 less than five times its own supplement. Mathematically, we can represent this as

                                          x = 5(180 - x) - 660

To solve this equation, we first distribute 5 to 180 - x, resulting in

                                                      900 - 5x

Then we can simplify the equation as follows: x = 900 - 5x - 660. Combining like terms, we get 6x = 240. Dividing both sides by 6, we find that x = 40.

Therefore, the measure of the angle is 40 degrees.

Given,

P(owning an automobile) = 0.6

P(owning a house) = 0.3

P(owning both an automobile and a house) = 0.2

We need to find the probability of owning an automobile or a house, but not both.

The probability of owning only an automobile can be calculated as:

P(owning only an automobile) = P(owning an automobile) - P(owning both an automobile and a house)

= 0.6 - 0.2

= 0.4

Similarly, the probability of owning only a house can be calculated as:

P(owning only a house) = P(owning a house) - P(owning both an automobile and a house)

= 0.3 - 0.2

= 0.1

Now, we can use the addition rule of probability to calculate the probability of owning an automobile or a house, but not both:

P(owning an automobile or a house, but not both) = P(owning only an automobile) + P(owning only a house)

= 0.4 + 0.1

= 0.5

Therefore, the probability that a person chosen at random owns an automobile or a house, but not both, is 0.5 or 50%.

Answer: 14

Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a

Answer:

r = -19

Step-by-step explanation:

To find the value of r, we can use the slope formula and the two given points:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (3, r) and (x2, y2) = (1, -7).

Substituting these values, we get:

6 = (-7 - r) / (1 - 3)

Simplifying and solving for r, we get:

6 = (-7 - r) / (-2)

Multiplying both sides by -2, we get:

-12 = 7 + r

Subtracting 7 from both sides, we get:

r = -19

Therefore, the value of r is -19.

Step-by-step explanation:

$800 x 0.07 = $56

($800 + $56) x 0.07 = $59.92

The total square footage (area) of the apartment is 385 square feet.

The total square footage, also known as the area, of an apartment is a measure of how much space the apartment has.

First, let's find the area of the 11ft by 11ft bedroom. To do this, we multiply the length and the width of the room. In mathematical terms, the area of a rectangle is equal to the length times the width. So, for the bedroom, the area is

=> 11ft * 11ft = 121 square feet.

Next, let's find the area of the 4ft by 6ft bathroom. The formula for the area of a rectangle is still the same, so the area of the bathroom is

=> 4ft * 6ft = 24 square feet.

Finally, we'll find the area of the multi-use living room/kitchen, which is 15ft by 16ft. The area of this room is

=> 15ft * 16ft = 240 square feet.

Now that we have the area of each room, we can add them together to find the total area of the apartment. So, the total area is

=> 121 square feet + 24 square feet + 240 square feet = 385 square feet.

Suppose we have a triangle with sides of length 3, 4, and 5 units. We can use the Pythagorean theorem to verify that this triangle is a right triangle: 3^2 + 4^2 = 9 + 16 = 25 = 5^2. Therefore, the angle opposite the side of length 5 is a right angle. We can also use the Law of Cosines to find the measure of one of the acute angles in the triangle. Let A, B, and C be the vertices of the triangle, with side AB of length 3, side BC of length 4, and side AC of length 5. Let angle C be the angle opposite the side of length 5. Then, by the Law of Cosines, we have cos(C) = (3^2 + 4^2 - 5^2) / (2 * 3 * 4) = -1/8. Since C is acute, we know that cos(C) is positive, so we take the absolute value to get cos(C) = 1/8. Therefore, we have C = arccos(1/8) ≈ 82.62 degrees.

The expression as a single summation in terms of k is:

∑k=1^m (V + (m + 1)/(m + 4)k + 3k) = mV + [(m + 1)(2m^2 + 3m + 4)]/2(m + 4)

The given expression involves two summations, so we need to simplify each one before combining:

∑k=1^m (V + (m + 1)/(m + 4)k + 3k) = ∑k=1^m V + (m + 1)/(m + 4)∑k=1^m k + 3∑k=1^m k

Using the formulas for the sum of the first m integers and the sum of the squares of the first m integers, we get:

∑k=1^m V + (m + 1)/(m + 4)(m(m+1)/2) + 3(m(m+1)/2)

= mV + (m + 1)/(m + 4)(m^2+m)/2 + 3(m^2+m)/2

= mV + [(m + 1)(2m^2 + 3m + 4)]/2(m + 4)

Combining the terms, we get:

∑k=1^m (V + (m + 1)/(m + 4)k + 3k) = mV + [(m + 1)(2m^2 + 3m + 4)]/2(m + 4)

Therefore, the expression as a single summation in terms of k is:

∑k=1^m (V + (m + 1)/(m + 4)k + 3k) = mV + [(m + 1)(2m^2 + 3m + 4)]/2(m + 4)

The set of sides (Square root of 6,8, Square root of 70) could be used to form a right-angle triangle.

Option (C) is correct.

What is a Pythagorean Triplet?

Pythagorean triples are defined as a²+b² = c², where a, b, and c are positive integers. These triples are denoted as (a, b, c). The perpendicular is a the base is b, and the hypotenuse is c of a right-angled triangle. The most well-known and tiniest triplets are (3,4,5).

For option (C), the set of sides is  (Square root of 6,8, Square root of 70).

Let the largest side in the above set is c = \(\sqrt{70}\)

so a = \(\sqrt{6}\) and b= 8,
Now by using the Pythagorean triplets property,

         LHS = a² + b²

                 = \((\sqrt{6})^2 + 8^{2}\)

                 = 6 + 64

                  = 70 -----------------(I)

Now, RHS = c²

                 = \((\sqrt{70})^2\)

                  = 70 -----------------(II)

By using (I) and (II), we can say that, LHS = RHS,

So the given set of sides holds the property of Pythagorean triplets.
Hence, the set of sides (Square root of 6,8, Square root of 70) could be used to form a right-angle triangle.

Option (C) is correct.

A condition that is impossible to satisfy has no solution.

Mathematics can be a powerful tool for solving many problems, but there are some issues that can't be solved.

In particular, any condition that is impossible to satisfy, such as the logical statement ‘this statement is false’, has no solution in mathematics. This is because the statement can’t be proven true or false, and so it can’t be solved.

An unsolvable condition is one that cannot be solved using any combination of logical and mathematical steps.

This means that no matter how much time and effort is put in, a solution to the problem cannot be discovered.

Here is an example of right skewed data:

Data: 1, 1, 1, 1, 2, 2, 2, 3, 3, 4

Mean: 2.5

Median: 2

Z-score of median: 0.5

As you can see, the mean is greater than the median. This is because the data is right skewed, meaning that there are a few extreme values on the right side of the distribution that are pulling the mean up.

The z-score of the median is positive because the median is greater than the mean.

Another example of right skewed data is the distribution of income. In most countries, most people earn a modest amount of income, but there are a few people who earn a very high income. This creates a right skewed distribution, with the mean being greater than the median.

In a right skewed distribution, the z-score of the median is positive because the median is closer to the mean than the mode. The mode is the most frequent value in the distribution, and it is usually located on the left side of the distribution in a right skewed distribution.

The mean is pulled to the right by the extreme values, but the median is not affected as much because it is not as sensitive to extreme values.
