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.

Answer: Probability = 90%

Step-by-step explanation:

In a drawer we have:

2 black shirts

7 white shirts

11 gray shirts

If we would randomly pick a shirt, what are the chances of it not being black?

To do that, we first need to calculate the probability of getting a black shirt.

To calculate that, we need to divide the number of black shirts by the total number of shirts.

Black shirts = 2

Total shirts = 2 + 7 + 11 = 20

That will be 2 black shirts divided by 20.

We get 0.1

If we multiply 0.1 by 100%, we get a 10% chance to get a black shirt.

Now, to know to chances of not getting a black shirt, we just need to subtract 10% from 100%.

And that will be 90% chances of not getting a black shirt.

Probability = 90%

No, but y = 8x is. There has to be an x after your number for it to be called a linear equation.

The value of \( (260 \cdot 5321+42 \cdot 28) \bmod 13 \) is 9.  

In the first paragraph, the given expression is evaluated using the order of operations. The product of 260 and 5321 is added to the product of 42 and 28. The resulting sum is then divided by 13, and the remainder (modulus) is determined.

In the second paragraph, we can explain the step-by-step calculation. Firstly, we multiply 260 by 5321, which equals 1,384,260. Next, we multiply 42 by 28, which equals 1,176. Then, we add these two products together, resulting in 1,385,436. Finally, we calculate the modulus by dividing this sum by 13, which gives us a remainder of 9. Therefore, the value of the given expression modulo 13 is 9.

The technique that is NOT used in variable selection is principal components analysis. Thus, option (B) is the correct option.

Variable selection is the process of selecting the appropriate variables (predictors) to incorporate in the statistical model. It is an important step in the modeling process, especially in multiple linear regression.

The technique(s) used in variable selection may vary depending on the purpose of the analysis and the features of the data.

There are various methods and techniques for variable selection, such as stepwise regression, ridge regression, lasso, and VIF regression. However, principal components analysis is not a variable selection technique but rather a dimensionality reduction technique.

PCA is used to reduce the number of predictors (variables) by transforming them into a smaller set of linearly uncorrelated variables known as principal components.

Using monthly payment formula, the Smith Family's total monthly payment is approximately $2,360.99.

To calculate the total monthly payment for the Smith Family, we need to consider the mortgage payment, insurance, property tax, and HOA fees.

1. Mortgage Payment:

The loan amount is the house price minus the down payment:

$350,000 - $70,000 = $280,000.

To calculate the monthly mortgage payment, we need to determine the interest rate and loan term. Since you mentioned it's a 15-year loan, we'll assume an interest rate of 4% (which can vary depending on market conditions and the borrower's credit).

We can use a mortgage calculator formula to calculate the monthly payment:

M = P [i(1 + i)ⁿ] / [(1 + i)ⁿ⁻¹]

Where:

M = Monthly mortgage payment

P = Loan amount

i = Monthly interest rate

n = Number of months

The monthly interest rate is the annual interest rate divided by 12, and the loan term is 15 years, which is 180 months.

i = 4% / 12 = 0.00333 (monthly interest rate)

n = 180 (loan term in months)

Plugging in the values into the formula:

M = $280,000 [0.00333(1 + 0.00333)¹⁸⁰] / [(1 + 0.00333)¹⁸⁰⁻¹]

Using a calculator, the monthly mortgage payment comes out to be approximately $2,014.99.

2. Insurance:

The monthly insurance payment is given as $66.

3. Property Tax:

The monthly property tax payment is given as $230.

4. HOA Fees:

The HOA fees are stated as $600 per year. To convert this to a monthly payment, we divide by 12 (months in a year): $600 / 12 = $50 per month.

Now, let's add up all these expenses:

Mortgage payment: $2,014.99

Insurance: $66

Property tax: $230

HOA fees: $50

Total monthly payment = Mortgage payment + Insurance + Property tax + HOA fees

Total monthly payment = $2,014.99 + $66 + $230 + $50

Total monthly payment = $2,360.99

Dereck and Sam are standing 3.1 feet apart.

The situation forms two right angle triangle.

A right angle triangle is a triangle that has one of its angles as 90 degrees.

Derek looks at a 10 foot basketball goal with an angle of elevation of 29°.

Sam looks at the goal with an angle of elevation of 43°.

Sam is directly in front of Dereck. Therefore,

Dereck distance from the base of the basket ball can be found as follows:

tan 29 = opposite / adjacent

opposite side = 10 ft - 5.83 ft = 4.17 ft

tan 29  = 4.17 / x

x = 4.17 / 0.55430905145

x = 7.52287913948

x = 7.523

Sam distance from the base of the basket ball can be found as follows

tan 43 = 4.17 / y

y = 4.17 / 0.93251508613

y = 4.47177752084

y = 4.471

The number of degrees of freedom we should use is 14 for makin95% confidence interval.

Degrees of freedom of an estimate is the number of independent pieces of information that went into calculating the estimate. It’s not quite the same as the number of items in the sample. In order to get the df for the estimate, you have to subtract 1 from the number of items.

Degree of freedom of sample size of n : n -1

When we don't have any idea about population standard deviation,

and also, the sample size is less than 30 .

We use t-distribution to calculated the statistics.

According to the question,

We are making a 95% confidence interval

The sample is 15 (<30) . So , we have to adjust and use a t-value instead of a Z score in order to account for the smaller sample size and using the sample SD.  

Note that the t-value depends on the degrees of freedom (df) as a reflection of sample size. When using the t-distribution to compute a confidence interval, df = n-1.

Answer:

You would multiply 30x15 to get 450miles per tank of gas.

Step-by-step explanation:

(a) the sample mean is 0.0494 and the sample variance is 0.000016, (b) the upper quartile is 0.04775, and the lower quartile is 0.0510, (c) the sample median is 0.04975, (d) boxplot is attached, and (e) the 5th and 95th percentiles of the inside diameter are 0.03974 and 0.056995 respectively.

(a) The mean = sum of all values divided by the number of values

μ = (x1 + x2 + ..... + xn)/n

n = 20

μ = (0.0395 + 0.0443+ 0.0450 + ... + 0.0550 + 0.0571)/20

μ = 0.9878/20

μ = 0.0494

(b) Variance = sum of squared deviations from the mean divided by n-1

s² = {(x1-μ)² + (x2-μ)² + .... (xn - μ)²)/(n-1)

s² = {(0.0395-0.0494)² + (0.0443-0.0494)² + .... +(0.0571-0.0494)²}/19

s² = 0.000016

(b) The minimum is 0.0395 and the maximum is 0.0571.

since the number of data is even, the median will be the average of two middle values.

M = Q2 = (0.0496+0.0499)/2 = 0.04975

Now, the first quartile is the median of the data values below the median

so Q1 = (0.0470+0.0485)/2 = 0.04775

And third quartile will be the median of the data values above the median

Q3 = (0.0504+0.0516)/2 = 0.0510

(c) Since we know that the number of data values is even, the median will be the average of the two middle values of the data set

so M = (0.0496+0.0499)/2

or M = 0.04975

(d) The boxplot is at maximum and minimum values. It will start in Q1 and end in Q3 and has a vertical line at the median or Q2.

The boxplot is attached.

(e) The 5th percentile means 0.05(n+1)th data value

or = 0.05(20+1) = 1.05th data value

5th percentile = 0.0550 + 0.05(0.0443-0.0395) = 0.03974

similarly,

95th percentile = 0.0550 + 0.95(0.0571-0.0550) = 0.056995

Therefore, (a) the sample mean is 0.0494 and the sample variance is 0.000016, (b) the upper quartile is 0.04775, and the lower quartile is 0.0510, (c) the sample median is 0.04975, and (e) the 5th and 95th percentiles of the inside diameter are 0.03974 and 0.056995 respectively.
