Answer:

  3.8 feet

Step-by-step explanation:

You want to know the distance from a building to the base of a 9 ft ladder that makes a 65° angle with the ground.

The cosine relation is ...

  Cos = Adjacent/Hypotenuse

In the right triangle that models this geometry, the hypotenuse is the length of the ladder (9 ft), and the distance from the base of the ladder to the base of the building is the side adjacent to the 65° angle.

Solving the above relation for the adjacent side, we have ...

  Adjacent = Hypotenuse · Cos

  distance to building = (9 ft)·cos(65°) ≈ 3.8 ft

The base of the ladder is about 3.8 ft from the base of the building.

A Type II Error, also known as a "false negative," is a statistical term used in hypothesis testing. In hypothesis testing, we start with two competing hypotheses: the null hypothesis (H0) and the alternative hypothesis (Ha).

The goal of hypothesis testing is to determine which hypothesis is more likely to be true given the data. A Type II Error occurs when we fail to reject the null hypothesis when it is actually false. In other words, we incorrectly conclude that the null hypothesis is true when it is actually false.

For example, consider a medical test for a certain disease. The null hypothesis is that the patient does not have the disease, and the alternative hypothesis is that the patient does have the disease.

If the test results are negative (i.e., the patient does not have the disease), and the patient actually does have the disease, then we have made a Type II Error.

The probability of making a Type II Error is represented by the Greek letter β (beta). A common goal in hypothesis testing is to keep the probability of making a Type II Error as low as possible, while also keeping the probability of making a Type I Error (false positive) low as well.

Hamid is going to take one of his T-shirts at random.

The probability of selecting a light blue T-shirt is \(\frac{1}{4}\) or \(0.25\).

a) To find the probability that the T-shirt will be grey, we need to determine the ratio of grey T-shirts to the total number of T-shirts.

From the given information, we know that Hamid has 2 grey T-shirts out of a total of 20 T-shirts.

Therefore, the probability of selecting a grey T-shirt at random is \(\frac{2}{20}\), which simplifies to \(\frac{1}{10}\) or \(0.1\).

b) To find the probability that the T-shirt will not be red, we need to determine the ratio of non-red T-shirts to the total number of T-shirts.

Hamid has 4 red T-shirts, so the number of non-red T-shirts is

\(20 - 4 = 16\).

Therefore, the probability of selecting a T-shirt that is not red is \(\frac{16}{20}\), which simplifies to \(\frac{4}{5}\) or \(0.8\).

c) If Hamid takes one of his blue T-shirts at random, we need to consider the ratio of blue T-shirts to the total number of T-shirts.

From the information provided, we know that Hamid has a total of 4 blue T-shirts.

Therefore, the probability of selecting a blue T-shirt at random is \(\frac{4}{20}\), which simplifies to \(\frac{1}{5}\) or \(0.2\).

d) If Hamid takes one of his blue T-shirts at random, the probability that the T-shirt is light blue depends on the ratio of light blue T-shirts to the total number of blue T-shirts.

From the information provided, there is only 1 light blue T-shirt and a total of 4 blue T-shirts.

Hence, the probability of selecting a light blue T-shirt is \(\frac{1}{4}\) or \(0.25\).

Answer: \(1460.96ft^3\)

Step-by-step explanation:

You have a cylinder and a cuboid. Find each of these figures' volume individually and add them together.

Cylinder:

height = 4ft

radius = 4ft

\(Formula: V=\pi r^2h\)

\(V=(3.14)(4ft)^2(4ft)\\V=(3.14)(16ft^2)(4ft)\\V=(3.14)(64ft^3)\\V=200.96ft^3\)

---------------------------------------------------------------------------------------------------

Cuboid:

\(Formula: V = l*w*h\)

\(V=(15ft)(7ft)(12ft)\\V=1260ft^3\)

The length BC for the similar triangle ∆ABC is derived to be equal to 20.

The triangles ABC and EBD are similar, this implies that the length AC of the smaller triangle is similar to the length ED of the larger triangle

similarly, BC is similar to BD so;

BC/(8 + BC) = 10/14

14BC = 10(8 + BC) {cross multiplication}

14BC = 80 + 10BC

14BC - 10BC = 80 {collect like terms}

4BC = 80

BC = 80/4 {divide through by 4}

GTT's expected market share is 45.45%, NCJ's expected market share is 31.82%, and Dash's expected market share is 22.73%. these percentages add up to 100%, as expected.

To find the long-run expected market share for each company, we need to use the concept of steady-state or equilibrium. In the long run, the market share of each company will remain constant if the number of customers gained is equal to the number of customers lost. This means that the rate of change of each company's market share will be zero.

Let's define the market share of each company at any point in time as follows:

GTT's market share = SGTT

NCJ's market share = SNCJ

Dash's market share = SDash

We can write the equations for the rate of change of each company's market share as follows:

dSGTT/dt = -0.2 SGTT + 0.05 SNCJ + 0.25 SDash

dSNCJ/dt = -0.05 SNCJ + 0.05 SGTT + 0.15 SDash

dSDash/dt = -0.15 SDash + 0.25 SGTT + 0.15 SNCJ

Note that the negative coefficients represent the percentage of customers lost by the company, and the positive coefficients represent the percentage of customers gained by the company.

To find the steady-state values of SGTT, SNCJ, and SDash, we need to set the rate of change of each company's market share to zero:

-0.2 SGTT + 0.05 SNCJ + 0.25 SDash = 0

-0.05 SNCJ + 0.05 SGTT + 0.15 SDash = 0

-0.15 SDash + 0.25 SGTT + 0.15 SNCJ = 0

We can solve these equations to get the steady-state values of SGTT, SNCJ, and SDash:

SGTT = 0.4545

SNCJ = 0.3182

SDash = 0.2273

Therefore, the expected long-run market share for each company is as follows:

GTT's expected market share: 45.45%

NCJ's expected market share: 31.82%

Dash's expected market share: 22.73%

Therefore, these percentages add up to 100%, as expected.

In a continuous probability distribution, a random variable can take any value in a specified range. (Option D)

A probability distribution refers to the mathematical function that provides the probabilities of occurrence of different possible outcomes for an experiment. Continuous probability distribution refers to a probability distribution with continuous types of data or random variables where the random variable can take on any value and is continuous. As there are infinite values that the variable can assume, the probability of the variable assuming any one specific value is zero. A continuous distribution is characterized by a range of values that are infinite, and therefore uncountable. The normal distribution is one example of a continuous distribution.

The x-intercepts of the function g(x) are at (1/2, 0) and (6, 0).

1. The x-intercepts occur when the value of g(x) is equal to zero.
2. So, we set g(x) equal to zero and solve for x.
3. By setting g(x) equal to zero, we get the equations:

g(1/2) = 0 and g(6) = 0.

To find the x-intercepts of the function g(x), we need to solve the equation g(x) = 0.

By substituting the given values, we get g(1/2) = 0 and g(6) = 0.

Setting g(x) equal to zero, we can solve for x. At x = 1/2 and x = 6, the value of g(x) is equal to zero, which means the function intersects the x-axis at these points.

The reduced row echelon form of the \(4\)×\(5\) matrix is

\(\left[\begin{array}{ccccc}1&0&1&0&-3\\0&1&5&0&-1\\0&0&0&1&4\\ 0&0&0&0&0\end{array}\right]\)

What is reduced row echelon form ?

When all of a matrix's pivots equal 1, and the pivots are the only non-zero elements in the fundamental columns, we say that the matrix is in reduced row echelon form.

Given that \(a_{1} ,a_{2}\) and \(a_{3}\) will be the independent vector, lets select them as the basis vector.

\(a_{1} =\left[\begin{array}{c}1&0&0\\0\end{array}\right]\) , \(a_{0} =\left[\begin{array}{c}0&1&0\\0\end{array}\right]\)

\(a_{3}= a_{1} +5a_{2}\)

   = \(\left[\begin{array}{c}1&0&0\\0\end{array}\right]+5\left[\begin{array}{c}0&1&0\\0\end{array}\right]\)

  =\(\left[\begin{array}{c}1&5&0\\0\end{array}\right]\)

\(a_{4}\) = \(\left[\begin{array}{c}0&0&0\\1\end{array}\right]\) and

\(a_{5} = -3a_{1} -a_{2} +4a_{4}\)

   = \(-3\left[\begin{array}{c}1&0&0\\0\end{array}\right]-\left[\begin{array}{c}0&1&0\\0\end{array}\right]+4\left[\begin{array}{c}0&0&0\\1\end{array}\right]\)

  =  \(\left[\begin{array}{c}-3&-1&0\\4\end{array}\right]\)

Hence the \(4\)×\(5\) matrix will be in the form

\(\left[\begin{array}{ccccc}1&0&1&0&-3\\0&1&5&0&-1\\0&0&0&0&0\\ 0&0&0&1&4\end{array}\right]\)

Since the one complete row is already zero, hence for calculating the row reduced echelon form we just need to replace the 3rd and 4th row.
