Answer:

x = 93°

y = 97°

Step-by-step explanation:

A cyclic quadrilateral is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle.

The opposite angles in a cyclic quadrilateral add up to 180°

⇒ y = 180° - 83°

⇒ y = 97°

Inscribed Angle Theorem:  the measure of an inscribed angle is half the measure of its intercepted arc.

Inscribed angle:  an angle with its vertex on the circle and whose sides are chords.

Intercepted arc:  the arc that is inside the inscribed angle and whose endpoints are on the angle.

x is an inscribed angle and (122° + 64°) is its intercepted arc.

ok it literally shows on the figure the length of the side AC is 6x + 7.

Answer:

AC = 25 units

Step-by-step explanation:

since ∠ A and ∠ C are congruent then the 2 legs BC and AB are congruent

BC = AB ( substitute values )

7x - 1 = 5x + 5 ( subtract 5x from both sides )

2x - 1 = 5 ( add 1 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

AC = 6x + 7 = 6(3) + 7 = 18 + 7 = 25

The length along the side of the barn of this rectangular plot is 150 feet.

The rectangle's area is the area enclosed by its perimeter and equals the product of its length and width. The space that is occupied within the boundaries of a rectangle is known as its area. It is calculated by finding the length divided by the width.

In order to maximize the area of the rectangular plot, the length of the fence will be twice the length of the width. Therefore, the width is 75 x 4 / 3 feet = 100 feet (since there are 75 sections of 4 feet each, and 3 sides of the rectangle are fenced, not just 2).

The length is twice the width, so the length is 2 x 100 feet = 200 feet.

Since the barn forms one side of the rectangle, the length along the barn is 150 feet (200 - 50 = 150).Thus, the length along the side of the barn of this rectangular plot is 150 feet.

Determine the significance level: The significance level is given as 5%.  Calculate the test statistic: The test statistic for a two-sample t-test is given by:
    t = (sample mean - hypothesized mean) / (standard error)

 In this case, the sample mean is 47.2, and the hypothesized mean is 50. The standard error can be calculated using the formula: standard error = sqrt(variance / sample size).  In this case, the variance is 121 and the sample size is 361. Calculate the degrees of freedom:  For a two-sample t-test, the degrees of freedom is calculated as the sum of the sample sizes minus 2.  In this case, the sample size is 361.  Determine the critical value:  Since the alternative hypothesis is two-tailed (different from 50), we divide the significance level by 2 (5% / 2) to get the critical value for each tail.

College students are often targeted by credit card companies with advertisements. A survey conducted at a university found that 65% of students had opened a new credit card account within the past year.

To answer your question, we need to use basic probability concepts. If 65% of students surveyed had opened a new credit card account within the past year, then the probability that a randomly chosen student has not opened a new credit card account is 1 - 0.65 = 0.35 or 35%.
Now, let's say we want to find the number of students we need to survey before finding one who had not opened a new account in the past year. This is equivalent to finding the number of trials before we get a success (i.e., finding a student who had not opened a new account).
We can use the formula for geometric distribution, which is:
P(X = k) = (1 - p)^(k-1) * p
where X is the number of trials before the first success, p is the probability of success, and k is the number of trials.
In our case, p = 0.35 (the probability of finding a student who had not opened a new account) and we want to find k (the number of trials).
We can set the probability to find a student who had not opened a new account to be greater than 0.5 (i.e., 50%) to ensure a high chance of success. So, we have:
P(X >= k) = 0.5
(1 - 0.35)^(k-1) * 0.35 = 0.5
Taking the logarithm of both sides and solving for k, we get:
k = log(0.5) / log(0.65)
k ≈ 3
Therefore, we would expect to survey about 3 students before finding one who had not opened a new credit card account in the past year.

In conclusion, college students are often targeted by credit card companies with advertisements. A survey conducted at a university found that 65% of students had opened a new credit card account within the past year. This statistic suggests that credit cards are popular among college students, who may be looking for ways to finance their education and living expenses. However, it is also important to note that credit card debt can be a major burden for students, especially if they are unable to make timely payments or manage their finances effectively. The probability analysis conducted in this answer shows that we would expect to survey only about 3 students before finding one who had not opened a new credit card account in the past year. This highlights the need for financial education and literacy programs for college students, to help them make informed decisions about credit card use and avoid potential debt problems.

At the end of 2018, the world population was approximately 7.53 billion people. This figure is calculated by taking the total population at the end of 2017, 7.4 billion people, and multiplying it by the population growth rate of 1.07%..

This means that the world population increased by approximately 130 million people in 2018. This population growth rate is consistent with the average growth rate of the world population over the last decade. While the population growth rate has been decreasing over the past few decades, it is still relatively high at 1.07%.

The high population growth rate is primarily due to high fertility rates in developing countries and a longer life expectancy in developed countries. This means that more people are born and fewer people die each year. As a result, the total population of the world increases each year.

12.56 cm²

Explanation

Given:

The area of the square = 16 cm²

What to find:

Area of the chess piece.

Step

The formula for an area, A of a square = L²

i.e A = L²

Since A is given to be 16 cm²

Therefore, the length is:

Note that the length of the square is equivalent to the diameter of circular-based chess.

∴ D = 4 cm

Radius, r = D/2 = 4cm/2 = 2 cm

Area of the chess piece = πr²

Putting r = 2 cm and π = 3.14

Area of the chess piece = 3.14 x (2cm)² = 3.14 x 4cm² = 12.56 cm²

Answer:

3n+12=45

Step-by-step explanation:

Because if you take 2 and put it in the place of n 32+12 =45 and take 45 and divide it by 12 and you will get 11.

Chebyshev's theorem says that for any set of observations, the proportion of values that lie within k standard deviations of the mean is  1 - 1/k².

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

We know that Chebyshev's theorem states that for a large class of distributions, no more than 1/k² of the distribution will be k standard deviations away from the mean.

This means that 1 - 1/k² of the distribution will be within k standard deviations from the mean.

Lets k = 1.8, the amount of the distribution that is within 1.8 standard deviations from the mean is;

1 - 1/1.8² = 0.6914

= 69.14%

Hence, Chebyshev's theorem says that for any set of observations, the proportion of values that lie within k standard deviations of the mean is  1 - 1/k².
