For what values of x and y is quadrilateral ABCD a parallelogram

Answers

Answer:

Option (A)

Step-by-step explanation:

By the property of a parallelogram,

Opposite sides of a parallelogram are equal and parallel to each other.

AD = BC and DC = AB

9x - 40 = 8x - 34

9x - 8x = 40 - 34

x = 6

4y + 20 = 6x - 4

4y - 6x = -24

2y - 3x = -12

Now we will substitute the value of x,

2y = 3x - 12

2y = 3(6) - 12

2y = 6

y = 3

Therefore, Option (A) will be the correct option.

The value of x is 6 and y is 3.

Given that,

ABCD is a parallelogram in which sides of parallelogram are,

AB = 8x- 34, BC = 6x- 4

CD = 9x-40, AD = 4y+20

We have to find,

The value of x and y in a quadrilateral ABCD ?

According to the question,

By the property of a parallelogram,

The opposite sides of a parallelogram are equal and parallel to each other.

AD = BC

CD = AB

Substitute the values of AD and BC and solve for the value of x and y,

$\rm 4y +20 = 6x -4 \\\\4y - 6x = -4 -20\\\\4y -6x = -24\\\\ Divide \ by \ 2 \ on \ both \ the \ sides\\\\ 2y - 3x = -12$

And

$CD = AB \\\\9x-40=8x-34\\\\9x-8x = 40-34\\\\x = 6$

Substitute the value of x in equation 1,

$2y-3x = -12\\\\2y - 3(6) = -12\\\\2y = -18=-12\\\\2y = -12+18\\\\2y = 6\\\\y = \dfrac{6}{2}\\\\y = 3$

Hence, The value of x is 6 and y is 3.

The spinner is spun 75 times. What is the experimental probability of spinning the given result? Round your answer to the nearest hundredth if necessary. Outcome A B C D Frequency 20 11 14 30 B or C

Answers

The experimental probability of spinning of B or C is 1/3.

In the given question, the spinner is spun 75 times.

We have to find the experimental probability of spinning of B or C.

The given data is:

Outcome A B C D

Frequency 20 11 14 30

Total frequency = 20 + 11 + 14 + 30

Total frequency = 75

The probability of spinning B = Frequency of B/Total Frequency

The probability of spinning B = 11/75

The probability of spinning C = Frequency of C/Total Frequency

The probability of spinning C = 14/75

Now the experimental probability of spinning of B or C;

P(B or C) = P(B) + P(C)

P(B or C) = 11/75 + 14/75

P(B or C) = (11 + 14)/75

P(B or C) = 25/75

P(B or C) = 1/3

Hence, the experimental probability of spinning of B or C is 1/3.

Answers

Noote that the measure of angle R is 27°. Here is how we got that.

Since the largest triangle is right triangle, the vertical segment is the perpendicular bisector of right angle with vertex at the center of circle.

Then we have

m∠R + 18° = 90°/2

m∠R + 18° = 45°

m∠R = 45° - 18°

m∠R = 27°

Answers

The probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 is approx b). 0.9428.

The intelligence quotient (IQ) test scores for adults are normally distributed with a population mean of 100 and a population standard deviation of 15. The standard deviation of the mean of a sample of 50 adults can be calculated as the population standard deviation divided by the square root of the sample size, or 15/√50 = 1.58.

Using a standard normal distribution table, the probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 can be calculated as the area under the standard normal curve between the z-scores corresponding to 98 and 103. These z-scores can be calculated using the formula z = (x - mean) / standard deviation, where x is the value of interest and mean is the population mean. The z-score for 98 is (98 - 100) / 1.58 = -1.27, and the z-score for 103 is (103 - 100) / 1.58 = 2.53.

The area under the standard normal curve between -1.27 and 2.53 can be found using a standard normal distribution table or a calculator with normal distribution functions. The probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 is approximately 0.9228, which is closest to the answer choice b. 0.9428.

Find the values of the trigonometric functions of theta from the information given. cot(theta) = 15, cos(theta) > 0 sin(theta) = cos(theta) = tan(theta) = csc(theta) = sec(theta) =

Answers

Given cot(theta) = 15 and cos(theta) > 0, we can find sin(theta), cos(theta), tan(theta), csc(theta), and sec(theta). We have sin(theta) = 1/√226, cos(theta) = 15/√226, tan(theta) = 1/15, csc(theta) = √226, and sec(theta) = √226/15.

First, we can use the fact that cot(theta) = cos(theta)/sin(theta) to find sin(theta) and cos(theta). Since cot(theta) = 15, we have:

cos(theta)/sin(theta) = 15

Multiplying both sides by sin(theta), we get:

cos(theta) = 15sin(theta)

Now, we can use the fact that cos(theta) > 0 to determine the sign of sin(theta). Since cos(theta) = 15sin(theta), we have:

15sin(theta) > 0

Dividing both sides by 15, we get:

sin(theta) > 0

So, we know that theta is in either the first or second quadrant.

Next, we can use the fact that sin(theta) = cos(theta) to find the values of sin(theta) and cos(theta). We have:

sin(theta) = cos(theta)

Using the Pythagorean identity, we know that:

sin^2(theta) + cos^2(theta) = 1

Substituting sin(theta) = cos(theta), we get:

2sin^2(theta) = 1

Solving for sin(theta), we get:

sin(theta) = 1/sqrt(2)

Since sin(theta) > 0, we know that theta is in the first quadrant.

Using the fact that sin(theta) = cos(theta), we also have:

cos(theta) = sin(theta) = 1/sqrt(2)

Now, we can find the remaining trigonometric functions. We have:

tan(theta) = sin(theta)/cos(theta) = (1/sqrt(2))/(1/sqrt(2)) = 1

csc(theta) = 1/sin(theta) = sqrt(2)

sec(theta) = 1/cos(theta) = sqrt(2)

Therefore, the values of the trigonometric functions of theta are:

sin(theta) = cos(theta) = 1/sqrt(2)
tan(theta) = 1
csc(theta) = sqrt(2)
sec(theta) = sqrt(2)

Given that cot(theta) = 15 and cos(theta) > 0, let's find the values of the trigonometric functions sin(theta), cos(theta), tan(theta), csc(theta), and sec(theta).

1. Since cot(theta) = 15, we can write it as cot(theta) = adjacent / opposite, where adjacent = 15 and opposite = 1 (since cotangent is the reciprocal of tangent). Using the Pythagorean theorem, we can find the hypotenuse:

hypotenuse = √(adjacent² + opposite²) = √(15² + 1²) = √226

2. Now we can find sin(theta) and cos(theta):
sin(theta) = opposite / hypotenuse = 1 / √226
cos(theta) = adjacent / hypotenuse = 15 / √226

3. To find tan(theta), we use the formula tan(theta) = sin(theta) / cos(theta):
tan(theta) = (1 / √226) / (15 / √226) = 1 / 15

4. Lastly, we can find the values of csc(theta) and sec(theta), which are the reciprocals of sin(theta) and cos(theta), respectively:
csc(theta) = √226 / 1 = √226
sec(theta) = √226 / 15

In summary:
sin(theta) = 1 / √226
cos(theta) = 15 / √226
tan(theta) = 1 / 15
csc(theta) = √226
sec(theta) = √226 / 15

Considering the three general types of geometry (flat, spherical, and saddle-shaped), when do the angles in a triangle add to 180°?

Answers

The angles in a triangle always add up to 180°, regardless of the type of geometry. This holds true for flat, spherical, and saddle-shaped geometries. The sum of the angles in any triangle is a fundamental property of Euclidean geometry.

This is known as the Triangle Sum Theorem.In spherical geometry, which is the geometry on the surface of a sphere, the sum of the angles in a spherical triangle also adds up to 180 degrees. However, the angles in a spherical triangle are measured in spherical degrees instead of regular degrees.

In hyperbolic geometry, which is a non-Euclidean geometry with a saddle-shaped curvature, the sum of the angles in a hyperbolic triangle is still 180 degrees, but the individual angles can have negative values or be greater than 180 degrees in terms of regular degrees.

The sampling method is just as simple as randomly assigning to persons (sample) and then selecting at random from those numbers using an automated mechanism. Finally, the numbers chosen represent the members from the sample.Within that method of sampling, researchers chose samples in two ways: the lottery method and using numbers generating software/random number table.

se tienen 10 parlantes idénticos que emiten sonido simultáneamente y el nivel de intensidad medido en un punto es 100 db, ¿cuál es el nivel de intensidad del sonido que emite cada parlante?

Answers

The total sound level at the point is 100 dB (10 dB x 10 speakers).

The formula for calculating the sound level emitted by each speaker is 10 * log (100 / 10) = 10 dB. This means that each speaker emits a sound level of 10 dB.

To calculate this, we first need to understand the principle of the logarithmic addition of sound levels. The logarithmic addition of sound levels states that when two sound waves with different amplitudes overlap, the resulting amplitude is the sum of the logarithms of the individual amplitudes.

For example, let's say we have two sound waves with amplitudes of 10 dB and 20 dB. The resulting amplitude will be 10 * log (10 + 20) = 10 * log (30) = 10 dB + 20 dB = 30 dB.

Therefore, in our example, the 10 speakers each emit a sound level of 10 dB. This means that when all 10 speakers play simultaneously, the total sound level at the point is 100 dB (10 dB x 10 speakers).
