When the rectangular garden has a length of 20 yards and a width of 42 yards the diagonal path will be \(\sqrt{2164}\) .

Pythagoras theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say a, b and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple.

Since we have a right-angled triangle, we can use the Pythagorean Theorem to find our answer. The Pythagorean Theorem states the following:

\(a^{2} +b^{2} =c^{2}\)

In this formula a and b represent the legs of the triangle and c represents the length of the hypotenuse.

Let's substitute our data from the question.

\(42^{2} +20^{2} =c^{2}\)

Square.

1764 + 400 = \(c^{2}\)

And finally take the root of both sides. We only need to use the positive solution, since the length of the hypotenuse can't be negative.

\(c = \sqrt{2164}\)

Answer: 53

Step-by-step explanation:

The length and width of the garden represent the legs of a right triangle, and the diagonal path represents the hypotenuse.

The Pythagorean Theorem states that a squared plus b squared equals c squared, where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse.

Let p equal the length of the diagonal path in yards.

Applying the Pythagorean Theorem gives us p squared equals forty-five squared plus twenty-eight squared.

Now square forty-five and twenty-eight to get p squared equals two thousand twenty-five plus seven hundred eighty-four.

Next, find the sum of two thousand twenty-five and seven hundred eighty-four, which is two thousand eight hundred nine.

Finally, calculate the square root of two thousand eight hundred nine to find that p equals fifty-three.

So the length of the diagonal path is fifty-three yards.

Step-by-step explanation: So, the function's graph cannot intersect the vertical asymptote because in order for it to do so, the graph should contain a point on the asymptote.

Yes, it is possible for the graph of y = f(x) to intersect a vertical asymptote, and It depends on the specific behavior and properties of the function f(x).

Given that,

The graph of a function is,

y = f (x)

Now, it is possible for the graph of y = f(x) to intersect a vertical asymptote.

While vertical asymptotes typically represent values of x where the function approaches infinity or negative infinity, there may be cases where the graph intersects the asymptote as it approaches or crosses it.

Hence, It depends on the specific behavior and properties of the function f(x).

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

The best interpretation of the statement "the chances of winning a prize are 1 out of 10" is that if many people buy a ticket, about 1 in 10 will win.

This statement means that for every 10 tickets sold, on average, only one ticket will win a prize. It does not guarantee that you will win a prize if you buy a single ticket or even several tickets. The probability of winning a prize remains the same for every ticket purchased. It is important to note that winning a prize in a lottery is largely a matter of luck, and the odds are always against the player. While buying more tickets may increase your chances of winning, it does not guarantee a win.

a. x1 has a binomial distribution with parameters n1 and p1, and x2 has a binomial distribution with parameters n2 and p2. b. The Central Limit Theorem is important in finding an approximate distribution for (Pi-P2) because it allows us to use a normal distribution to approximate the binomial distribution when the sample size is large enough.

a. The distributions of x1 and x2 can be described as follows:
x1 has a binomial distribution with parameters n1 and p1 (success probability in the first set of trials), denoted as B(n1, p1). Similarly, x2 has a binomial distribution with parameters n2 and p2 (success probability in the second set of trials), denoted as B(n2, p2).

b. The Central Limit Theorem (CLT) is important in finding an approximate distribution for (p1 - p2) because it allows us to approximate the difference of two binomial distributions by using a normal distribution. When n1 and n2 are large enough, the CLT states that the sampling distribution of the sample proportions will be approximately normal, even if the original populations are not normal. This makes it easier to make inferences about (p1 - p2) using well-known properties and techniques associated with normal distributions.

The total amount that must be repaid is $139,076.12.

Annual simple interest is a type of interest that is calculated on the principal amount of a loan or investment for a one-year period. Simple interest is a fixed percentage of the principal amount, which is added to the principal at regular intervals. The interest is calculated only on the original principal amount and does not include any interest earned on the interest itself.

Compound interest is a type of interest that is calculated not only on the principal amount of a loan or investment, but also on the interest earned on that principal amount over time. In other words, compound interest is interest that is added to the principal amount, and then interest is calculated on the new total amount (principal + interest). This process is repeated at regular intervals, such as monthly or annually.

In the given question, The total amount that must be repaid can be found using the simple interest formula:

I = Prt

Where:

P = principal amount borrowed = $87,495

r = annual interest rate = 8.355%

t = time period in years = 7

So, substituting the values we get:

I = 87,495 * 0.08355 * 7 = 51,581.12

Therefore, the total amount that must be repaid is:

87,495 + 51,581.12 = 139,076.12

Rounding to the nearest cent, the answer is $139,076.12.

because  negative four raised to the fourth power divided by negative four raised to the second power = negative four raised to the second power

negative four raised to the sixth power divided by negative four raised to the fourth power also = negative four raised to the second power

The answer is A: negative four raised to the second power divided by negative four raised to the fourth power. This is obtained by applying the rules of exponents, specifically, when dividing with the same base, subtract the exponents.

This question pertains to exponents division rules. According to the rule of Power of a Power in exponents, when you divide expressions with the same base, you subtract the exponents. So if you have negative four raised to the fourth power (-4⁴) and you want to divide it by negative four raised to the second power (-4²), you subtract 2 from 4 to get an exponent of 2. This results in a negative four raised to the second power (-4²). So, the correct option from the given choices in your question is A: negative four raised to the second power divided by negative four raised to the fourth power.

The weighted least squares estimator (owLS) is better when errors have different variances as it incorporates the varying precision of measurements, resulting in a smaller variance and more reliable estimates compared to the least squares estimator (LS).

(a) The least squares estimator for parameter a is obtained by minimizing the sum of squared errors. In matrix notation, the estimator can be derived as a = \((X'X)^(-1)X'y\), where X is the design matrix and y is the response vector.

(b) Considering errors with different variances, the weighted least squares estimator (owLS) is used. It incorporates weights proportional to the inverse of the variances. The owLS estimator can be calculated as a = \((X'W X)^(-1)X'W\) y, where W is a diagonal matrix containing the inverse variances of the errors.

(c) To compare the two estimators, their expected values and variances need to be computed. The least squares estimator (LS) has an unbiased expected value and its variance is \(\alpha ^2(X'X)^(-1).\) The owLS estimator has the same unbiased expected value but a smaller variance, which is given by \(\alpha ^2(X'WX)^(-1).\)

The owLS estimator is better when errors have different variances because it takes into account the varying precision of the measurements. By assigning higher weights to more precise measurements, it reduces the impact of less accurate data on the estimated parameter. This results in a smaller variance for the owLS estimator compared to the LS estimator, making it more efficient and providing more reliable estimates.

The mean absolute deviation (MAD), a measure of variability, illustrates the typical distance between an observation's mean and its variation. MAD uses the data's original units to facilitate interpretation.

Greater values indicate a wider range of data points than the average. The term "variability" refers to how much a data collection varies from one constituent to another. Variability measures reflect the level and magnitude of change within the data collection.

The interquartile range and the mean average deviation are the two methods for calculating variability that are required by the requirements for sixth-grade pupils.

The majority of the data values are fairly near to the mean, as shown by a tiny mean absolute deviation. We can infer from a large mean absolute deviation that numerous data values are dispersed widely from the mean.
