By using pythagorean theorem, the length of the missing side is 12 feet.

What is the Pythagorean theorem?

Pythagoras' theorem is a fundamental principle in geometry that relates to the three sides of a right-angled triangle. It states that:

"In a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides."

In mathematical terms, if a, b, and c are the lengths of the sides of a right-angled triangle, where c is the hypotenuse, then the theorem can be written as:

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

We can use the Pythagorean theorem to determine the length of the missing side if we know that the given sides form a right triangle.

In this case, we have two sides of the triangle given: 7.2 feet and 9.6 feet. Let's assume that c is the length of the hypotenuse.

If the triangle is a right triangle, then we can use the Pythagorean theorem to solve for c:

\(c^2 = 7.2^2 + 9.6^2\)

\(c^2 = 51.84 + 92.16\)

\(c^2 = 144\)

\(c = \sqrt{144}\)

c = 12 feet

Therefore, if the triangle is a right triangle, then the length of the missing side is 12 feet.

Now let's explain the reasoning behind each value:

The expression -9 represents the number -9, so its value is -9.

Similarly, the expression 7 represents the number 7, so its value is 7.

The expression -2 represents the number -2, so its value is -2.

When an expression is labeled as "Undefined," it means that there is no specific value assigned or that it does not have a defined value.

For the expression h(3.999), its value is undefined because the function h(x) is not defined for the input 3.999.

The expression h(4) has a value of 8, indicating that when we input 4 into the function h(x), it returns 8.

Similarly, the expression h(4.0001) has an undefined value because the function h(x) is not defined for the input 4.0001.

Lastly, the expression h(9) also has an undefined value because the function h(x) is not defined for the input 9.

The probability of no loads occurring during that period is at most 0.3 exists 3.2 years.

Given: Mean time between occurrence = 0.4 year

A number of loads expected to occur during a 4 year period

Period = 4

Mean time = 0.4

Let the formula = Period/Mean Time

The number of loads expected to occur during a 4-year period

= 4/0.4 = 10 loads

B. Probability that more than 11 loads occur during 4 year period

The expected number of loads during 4-year period = 10 (from A above)

mean = 10

Using Poisson distribution,

P(k events in interval)= (λ^k * e^-k)/k!

where: k = 0, 1, 2,3,4, . . ., 11 and λ = 10.

P(k = 0) = (1\(0^0\) × \(e^{-10\))/0! = 0.000045

P(k = 1) = (1\(0^1\) ×  \(e^{-10\))/1! = 0.000454

P(k = 2) = (10² ×  \(e^{-10\))/2! = 0.00227

P(k = 3) = (10³ ×  \(e^{-10\))/3! = 0.007567

P(k = 4) = (1\(0^4\) ×  \(e^{-10\))/4! = 0.018917

P(k = 5) = (1\(0^5\) ×  \(e^{-10\))/5! = 0.037833

P(k = 6) = (1\(0^6\) ×  \(e^{-10\))/6! = 0.063055

P(k = 7) = (1\(0^7\) ×  \(e^{-10\))/7! = 0.090079

P(k = 8) = (1\(0^8\) ×  \(e^{-10\))/8! = 0.112599

P(k = 9) = (1\(0^9\) ×  \(e^{-10\))/9! = 0.12511

P(k = 10) = (1\(0^{10\) ×  \(e^{-10\))/10! = 0.12511

P(k = 11) = (1\(0^{11\) ×  \(e^{-10\))/11! = 0.113736

The probability that more than 11 loads occur during a 4-year period is then given by the following Express

1 - [P(k = 0) + P(k = 1) + P(k = 2) + . . . + P(k = 11)]

substitute the values in the above equation, we get

= 1 - [0.000045 + 0.000454 + 0.00227 + 0.007567 + 0.018917 + 0.037833 + 0.063055 + 0.090079 + 0.112599 + 0.12511+ 0.12511 + 0.113736]

simplifying the equation, we get

= 1 - 0.571665 = 0.428335

C. How long must a time period be so that the probability of no loads occurring during that period is at most 0.3

(λ^0 * e^-λ)/0! = 0.3

⇒ e^-λ/1 = 0.3

simplifying the above equation, we get

⇒ e^-λ = 0.3

⇒ -λ = ln 0.3

⇒ -λ = -1.204

⇒ λ = 1.204

The time period = 4 years / 1.204

Time period = 3.2 years

Answer:

\(x = 180\)

Step-by-step explanation:

Solve the value of \(x\) :

\(0.25x + 7 = \frac{1}{3}x - 8\)

-Combine \(\frac{1}{3}x\) and \(0.25x\) by subtracting \(0.25x\) by \(\frac{1}{3}x\) :

\(0.25x - \frac{1}{3}x + 7 = \frac{1}{3}x - \frac{1}{3}x - 8\)

\(-\frac{1}{12}x + 7 = -8\)

-Subtract \(7\) on both sides:

\(-\frac{1}{12}x + 7 - 7 = -8 - 7\)

\(-\frac{1}{12}x = -15\)

-Multiply both sides by \(-12\), the reciprocal of \(-\frac{1}{12}\) :

\(\frac{-\frac{1}{12}x}{-\frac{1}{12}} = \frac{-15}{-\frac{1}{12}}\)

\(x = -15 (-12)\)

\(x = 180\)

Therefore, the value of \(x\) is \(180\).

The critical points are (0, 1), (0, -1), (2, 1), and (2, -1).

To find the critical points of the function f(x, y) = x^3 + y^3 - 3x^2 - 3y + 10, we need to find the points where the gradient (∇f) is equal to zero or is undefined.

Taking the partial derivatives of f(x, y) with respect to x and y:

∂f/∂x = 3x^2 - 6x

∂f/∂y = 3y^2 - 3

Setting these partial derivatives equal to zero, we have:

3x^2 - 6x = 0

3y^2 - 3 = 0

Simplifying these equations, we get:

x^2 - 2x = 0

y^2 - 1 = 0

Factoring the equations, we have:

x(x - 2) = 0

y^2 - 1 = 0

From the first equation, we have two possibilities for x:

x = 0

x - 2 = 0 --> x = 2

Given that the correlation between two variables is r=0.23. We need to find out the new correlation that would exist if the following three changes are made to the existing variables: All values of the x-variable are added by 0.14. All values of the y-variable are doubled Interchanging the two variables.  the correct option is B. 0.37.

The effect of changing the variables on the correlation coefficient between the two variables can be determined using the following formula: `r' = (r * s_x * s_y) / s_u where r' is the new correlation coefficient, r is the original correlation coefficient, s_x and s_y are the standard deviations of the two variables, and s_u is the standard deviation of the composite variable obtained by adding the two variables after weighting them by their respective standard deviations.

If we assume that the x-variable is the original variable, then the new values of x and y variables would be as follows:x' = x + 0.14 (since all values of the x-variable are added by 0.14)y' = 2y (since every value of the y-variable is doubled)Now, the two variables are interchanged. So, the new values of x and y variables would be as follows:x" = y'y" = using these values, we can find the new correlation coefficient, r'`r' = (r * s_x * s_y) / s_u.

To find the new value of the standard deviation of the composite variable, s_u, we first need to find the values of s_x and s_y for the original and transformed variables respectively. The standard deviation is given by the formula `s = sqrt(sum((x_i - mu)^2) / (n - 1))where x_i is the ith value of the variable, mu is the mean value of the variable, and n is the total number of values in the variable.

For the original variables, we have:r = 0.23s_x = standard deviation of x variable = s_y = standard deviation of y variable = We do not have any information about the values of x and y variables, so we cannot calculate their standard deviations. For the transformed variables, we have:x' = x + 0.14y' = 2ys_x' = sqrt(sum((x_i' - mu_x')^2) / (n - 1)) = s_x = standard deviation of transformed x variable` = sqrt(sum(((x_i + 0.14) - mu_x')^2) / (n - 1)) = s_x'y' = 2ys_y' = sqrt(sum((y_i' - mu_y')^2) / (n - 1)) = 2s_y = standard deviation of transformed y variable` = sqrt(sum((2y_i - mu_y')^2) / (n - 1)) = 2s_yNow, we can substitute all the values in the formula for the new correlation coefficient and simplify:

r' = (r * s_x * s_y) / s_ur' = (0.23 * s_x' * s_y') / sqrt(s_x'^2 + s_y'^2)r' = (0.23 * s_x * 2s_y) / sqrt((s_x^2 + 2 * 0.14 * s_x + 0.14^2) + (4 * s_y^2))r' = (0.46 * s_x * s_y) / sqrt(s_x^2 + 0.0396 + 4 * s_y^2)Now, we can substitute the value of s_x = s_y = in the above formula:r' = (0.46 * * ) / sqrt( + 0.0396 + 4 * )r' = (0.46 * ) / sqrt( + 0.1584 + )r' = (0.46 * ) / sqrt(r' = (0.46 * ) / sqrt(r' = (0.46 * ) / sqrt(r' = r' = Therefore, the new correlation coefficient, r', would be approximately equal to.

In a hypothesis testing context, before examining the data, one should establish a null hypothesis and an alternative hypothesis.

Before conducting any analysis or collecting data, it is crucial to define the null hypothesis and the alternative hypothesis. The null hypothesis (H₀) represents the assumption of no effect or no difference between groups or variables, while the alternative hypothesis (H₁) represents the claim or hypothesis being tested. These hypotheses help define the question or statement that the researcher wants to investigate.

Formulating the null and alternative hypotheses before examining the data is important to ensure the hypothesis testing process is objective and guided by clear expectations. It helps to establish a framework for statistical analysis and allows for making informed decisions based on the evidence provided by the data.

Additionally, this initial step ensures that the hypothesis testing process remains rigorous and avoids potential biases that may arise from post hoc analyses.

To write eighty-six thousand and one hundred sixty-three thousandths as a decimal number, we can express it as 86,163.000.

To write eighty-six thousand and one hundred sixty-three thousandths as a decimal number, we need to convert the whole number and the fraction into decimals separately.

Let's start with the whole number, which is 86,000.

To convert it into a decimal, we move the decimal point three places to the left since there are three zeros after the 86.

This gives us 86.000. Now, let's focus on the fraction, which is one hundred sixty-three thousandths.

This fraction can be written as 163/1000. To convert it into a decimal, we divide the numerator (163) by the denominator (1000). This gives us 0.163.

Finally, we add the decimal form of the whole number (86.000) and the decimal form of the fraction (0.163) together.

86.000 + 0.163 = 86.163

Therefore, eighty-six thousand and one hundred sixty-three thousandths can be written as a decimal number as 86.163.
