You are given an isosceles trapezoid ABCD with median XY. Complete the following.

Answers

The measures of the angle m∠DAB for the isosceles trapezoid is equal to 75°.

What is an Isosceles trapezoid

This is a trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. The opposite angles are supplementary which implies they sum up to 180°.

The upper base angles m∠DAB and m∠ADC are equal, and angles m∠ADC and m∠DCB are supplementary, so we shall calculate for the angle m∠DAB by first evaluating for angle m∠ADC as follows:

m∠ADC + m∠DCB = 180° {opposite angles are supplementary}

m∠ADC + 105° = 180°

m∠ADC = 180° - 105° {subtract 105° from both sides}

m∠ADC = 75°

m∠ADC = m∠DAB = 75°

Therefore, the measures of the angle m∠DAB for the isosceles trapezoid is equal to 75°.

Find the total area S₁ + S₂ under the normal distribution, where S, is the area to the left of z=-2.15
and S₂ is the area to the right of z =
= 1.62.

Answers

Answer:

the total area under the normal distribution is 0.0684.

Step-by-step explanation:

We can use a standard normal distribution table or a calculator to find the areas S₁ and S₂.

Using a standard normal distribution table or calculator, we find:

S₁ = 0.0158

S₂ = 0.0526

To find the total area S₁ + S₂, we simply add these two values:

S₁ + S₂ = 0.0158 + 0.0526 = 0.0684

Therefore, the total area under the normal distribution is 0.0684.

The probability that precious has a job is 3/8. The probability that she’s a university student is 1/4. The probability that she works and is a university student is 13/24. What is the probability that precious has a job or a university student

Answers

The probability that Precious has a job or is a university student is 1/12.

What is probability ?

Probability is a measure of the likelihood or chance that an event will occur. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event can be calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
Probability can be used in a wide variety of applications, such as in gambling, statistics, and science. In these fields, probability is used to make predictions, analyze data, and test hypotheses.

According to the question:
To find the probability that Precious has a job or is a university student, we can use the formula:

P(job or university student) = P(job) + P(university student) - P(job and university student)

We are given that the probability that Precious has a job is 3/8, and the probability that she is a university student is 1/4. We are also given that the probability that she works and is a university student is 13/24.

So, we can substitute these probabilities into the formula:

P(job or university student) = 3/8 + 1/4 - 13/24

We can simplify by finding a common denominator:

P(job or university student) = 9/24 + 6/24 - 13/24

P(job or university student) = 2/24

Finally, we can simplify by dividing both the numerator and denominator by 2:

P(job or university student) = 1/12

Therefore, the probability that Precious has a job or is a university student is 1/12.

g(x) is a function as defined below





Which of the graphs shows g(x)?

Answers

We can conclude by answering the provided question that Looking at the choices, the graph displaying g(x) is the one designated as (D). It corresponds to the properties of the function mentioned above.

What is function?

In mathematics, a function appears to be a connection between two groups of numbers in which each member of the first set (known as the domain) correlates to a specific member of the second set (called the range). In other terms, a function takes input from one set and generates output from another. The variable x has frequently been used to represent inputs, and the variable y has been used to represent outcomes. A formula or a grid can be used to describe a function. For example, the formula y = 2x + 1 depicts a functional form in which each value of x gives a unique value of y.

We can deduce from the provided function:

g(x) = 0 when x = 0.

For 0 x 1, g(x) = x2.

g(x) = 2 - x for 1 x 2.

g(x) = 0 when x > 2.

So, to draw the graph of g(x), we can join the points (x, g(x)) for various values of x within the specified intervals.

Looking at the choices, the graph displaying g(x) is the one designated as (D). It corresponds to the properties of the function mentioned above.

Answers

Sample selection bias occurs when a selection process influences the availability of data and that process is related to the dependent variable.

The correct answer is an option (c)

We know that in statistics the sample selection bias is nothing but the bias that results from the failure to ensure the proper randomization of a sample.

It is caused by choosing non-random data for statistical analysis.

Here a subset of the data is excluded from the study, due to the flaws in the sample selection process.

There types of sample selection bias are: pre-screening bias, self-selection bias, exclusion bias, and observer bias.

Classify each pair of lines as parallel, perpendicular, or neither.

y + 2 = 5x and 5y - x = -2 ​

Answers

The pairs of lines are classified as: perpendicular, parallel, neither, neither.

The slopes of the first pair of lines differ, making them neither parallel nor perpendicular. The slopes of the first and second lines are 1/2 and -2, respectively.

The second set of lines is perpendicular because the slopes of the first line, which is -3, and the second line, which is 1/3, are the opposites of each other.

The third set of lines have varying slopes and are neither equal nor perpendicular. The slopes of the two lines are -2/3 for the first line and 6/4 for the second, which reduces to 3/2.

To classify each pair of lines as parallel, perpendicular, or neither, we need to compare their slopes.

2y = x and y = -2x + 6

The first equation can be written in slope-intercept form as y = (1/2)x, which means its slope is 1/2. The second equation can be written in slope-intercept form as y = -2x + 6, which means its slope is -2. Since the slopes are negative reciprocals of each other, these lines are perpendicular.

y + 3x = 1 and 2y = -6(x - 1)

The first equation can be written in slope-intercept form as y = -3x + 1, which means its slope is -3. The second equation can be written in slope-intercept form as y = -3x + 3, which means its slope is also -3. Since the slopes are the same, these lines are parallel.

3y + 2x = -3 and 4y = 6x + 12

The first equation can be written in slope-intercept form as y = (-2/3)x - 1, which means its slope is -2/3. The second equation can be written in slope-intercept form as y = (3/2)x + 3, which means its slope is 3/2. Since the slopes are not equal and not negative reciprocals of each other, these lines are neither parallel nor perpendicular.

y + 2 = 5x and 5y - x = -2

The first equation can be written in slope-intercept form as y = 5x - 2, which means its slope is 5. The second equation can be written in slope-intercept form as y = (1/5)x - 2/5, which means its slope is 1/5. Since the slopes are not equal and not negative reciprocals of each other, these lines are neither parallel nor perpendicular.

Answers

Answer:

One method for solving quadratic equations is factoring. Factoring involves finding the two factors of a quadratic equation and setting each factor equal to zero. For example, the quadratic equation x^2 + 5x + 6 = 0 can be factored into (x + 2)(x + 3) = 0. Setting each factor equal to zero, we get x + 2 = 0 and x + 3 = 0, which gives us the solutions x = -2 and x = -3.

Another method for solving quadratic equations is completing the square. This method involves manipulating the equation to transform it into a perfect square trinomial, which can then be easily solved. For example, the quadratic equation x^2 + 6x - 7 = 0 can be completed by adding (6/2)^2 = 9 to both sides of the equation, resulting in x^2 + 6x - 7 + 9 = 9, or (x + 3)^2 = 16. Taking the square root of both sides and solving for x, we get x = -3 + 4 or x = -3 - 4, giving us the solutions x = 1 and x = -7.

A third method for solving quadratic equations is using the quadratic formula. The quadratic formula is derived from completing the square and gives us the solutions to any quadratic equation. For the quadratic equation ax^2 + bx + c = 0, the quadratic formula is x = (-b ± √(b^2 - 4ac)) / 2a. For example, the quadratic equation 2x^2 + 3x - 2 = 0 can be solved using the quadratic formula, giving us x = (-3 ± √(3^2 - 4(2)(-2))) / 2(2), or x = (-3 ± √25) / 4. This gives us the solutions x = -1/2 and x = -2.

In responding to my classmates, I would choose the method based on the specific quadratic equation given. For example, if the quadratic equation is easily factorable, I would use the factoring method. If it is not factorable, I would use either completing the square or the quadratic formula. Completing the square may be preferable if the coefficient of x^2 is 1, while the quadratic formula can be used for any quadratic equation.

What is the value of x to the nearest degree 11 10

Answers

The angle x to the nearest degree is 47°.

How to find the value of a angle to the nearest degree?

To find the value of the angle to the nearest degree, we can use the inverse tangent function, which relates the opposite and adjacent sides of a right triangle to the angle opposite the opposite side. Specifically, we can use the formula:

tan(A) = opposite/adjacent where A is the value of angle.

Here, "opposite" is the height of the triangle (11) and "adjacent" is the base of the triangle (10).

We can solve for x by taking the inverse tangent (or arctangent) of both sides of the equation:

[tex]$ \rm x = tan^{-1} \left( \frac{opposite }{adjacent}\right)[/tex]

[tex]$ \rm x = tan^{-1} \left( \frac{11}{10}\right)[/tex]

Using a calculator, we can evaluate this expression to find

x ≈ 47.34 °

To round this to the nearest degree, we can look at the decimal part of the answer (0.34) and see that it is closer to 0.5 than 0. Therefore, we can round up to the nearest degree x ≈ 47 degrees

So, the angle x to the nearest degree is 47 degrees.

Answers

If 7 people each got a train ticket instead of buying one train ticket, they would pay a total of £28.70, which is £24.60 more than the cost of one train ticket.

If one train ticket costs £4.10, then the cost of 7 train tickets would be:

7 x £4.10 = £28.70

Therefore, if 7 people each got a train ticket instead of one train, they would pay a total of £28.70.

To find out how much more money they would pay in total, we need to subtract the cost of one train ticket from the total cost of 7 train tickets:

How many insects were consumed throughout the month by the pitcher plants?

Answers

Answer:

Step-by-step explanation:

The number of insects consumed by pitcher plants is essential for their survival and growth, and it is fascinating to observe this unique aspect of their carnivorous nature.

Pitcher plants are carnivorous plants that trap and digest insects to obtain nutrients. The exact number of insects consumed by pitcher plants in a month can vary depending on factors such as the species of pitcher plant, its size, and the local environment. However, studies have estimated that a single pitcher plant can consume anywhere from a few dozen to hundreds of insects per month.

The mechanism of the pitcher plant is quite interesting. Insects are lured into the plant by its color and sweet-smelling nectar. Once inside, the insect becomes trapped and is unable to escape due to the slippery inner walls of the pitcher. The plant then secretes digestive enzymes that break down the insect's tissues, allowing the plant to absorb the nutrients.

Interestingly, not all insects are consumed by pitcher plants. They tend to prefer smaller insects such as ants and flies, but larger insects such as bees and wasps may occasionally become trapped as well.

Answer:

Width = 10

Step-by-step explanation:

let length = X

width = 3X - 2

Area = length x width

40 = X x (3X - 2)

40 = 3X^2 - 2X

therefore 3X^2 - 2x - 40 = 0

3x^2 + 10x - 12x - 40 = 0

x(3x + 10) - 4(3x + 10) = 0

(x - 4) (3x + 10) = 0

(x - 4) = 0

x = 4

(3x + 10) = 0

3x = - 10

x = -10/3

Since the lenght can't be negative, we'll work with x = 4

Therefore the width = 3x - 2

For this word, we have k1 = 2 (for the two "a"s) and k2 = 1 (for the "b"). Plugging these values into the formula, we get

P(6; 2, 1) = 6! / (2! 1!) = 360 / 2 = 180

Therefore, there are 180 distinguishable arrangements of the word "acbens."

(b) The word "baaben" also has 6 letters, but this time there are three "a"s and two "b"s. Using the same formula as before, we have k1 = 3 and k2 = 2, so

P(6; 3, 2) = 6! / (3! 2!) = 720 / 12 = 60

Therefore, there are 60 distinguishable arrangements of the word "baaben."

(c) The word "aabbba" has 6 letters, but this time there are four "a"s and two "b"s. Using the same formula as before, we have k1 = 4 and k2 = 2, so

P(6; 4, 2) = 6! / (4! 2!) = 720 / 48 = 15

The rectangle that contains Retention Pond 1 is translated 8 units to the right and 13 units down.
What are the coordinates of the image? Does the image have the same area as the rectangle that
contains Retention Pond 1? Explain your reasoning.

Answers

Thus, the coordinates of the image after the given translations is found as: (0, -5),  (0, -10), (4, -10) and  (4, -5).

Explain about the translation:

A translation in mathematics is a transformation of such a curve or a this double object that entails moving the curve or item from point to point along its graph. We have different terms to express this kind of alteration according to the nature of translation.

Initial coordinates of Retention Pond 1:

(-8,8) , (-8, 3), (-4, 3) and (-4, 8)

After the translation of 8 units to the right. Add 8 to each x-coordinates.

After the translation of  13 units down. subtract 13 to each y-coordinates.

(-8,8)  = (-8 + 8,8 - 13)  = (0, -5)

(-8, 3) =  (-8 + 8, 3 - 13) = (0, -10)

(-4, 3) = (-4 + 8, 3 - 13) = (4, -10)

(-4, 8) = (-4 + 8, 8 - 13)  = (4, -5)

Thus, the coordinates of the image after the given translations is found as: (0, -5),  (0, -10), (4, -10) and  (4, -5). There will be no change in the area.

A submarine is descending to examine the seafloor 2,100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarine elevation and time (WRITE AN EQUATION NOT ANSWER EQUATION ​

Answers

Equation:

Let "e" be the elevation of the submarine and "t" be the time taken to descend.

Then, the equation representing the relationship between the submarine elevation and time is:

e = -105t + 2100

where the coefficient of "t" (-105) represents the rate of descent of the submarine, and the constant term (2100) represents the initial elevation of the submarine.

determine the surface area of the pyramid

Answers

Answer:

64 in^2.

Step-by-step explanation:

The surface consists of 4 congruent triangles and a square base.

Area of 1 triangle = 1/2 * 4*6  = 12.

Area of the base = 4*4 = 16.

So the required surface area

= 4*12 + 16

= 64 in^2.
