suppose that 36% of people own dogs. if you pick two people at random, what is the probability that they both own a dog? give your answer as a decimal (to at least 3 places) or fraction
Thus, the probability that two people picked at random both own a dog is 0.1296 or 1296/10000.
To solve this problem, we need to use the formula for calculating the probability of independent events: P(A and B) = P(A) x P(B).
In this case, let A be the event that the first person owns a dog and B be the event that the second person owns a dog.
We know that P(A) = 0.36, or 36% chance that the first person owns a dog. Since the events are independent, P(B) is also 0.36.
So, the probability of both events occurring (both people owning dogs) is:
P(A and B) = P(A) x P(B)
= 0.36 x 0.36
= 0.1296
This can also be expressed as a fraction:
P(A and B) = 36/100 x 36/100
= 1296/10000
Therefore, the probability that two people picked at random both own a dog is 0.1296 or 1296/10000.

The answer to the trigonometry question in the picture attached is:
= cos θ / [sin θ * (1 - sin θ)] * (1 + sin θ)
Here is the step by step approach to solving the trigonometrySimplify 1-csc θ as follows:
1 - csc θ = (1 - csc θ)(1 + csc θ) / (1 + csc θ)
= 1 - csc^2 θ / (1 + csc θ)
= 1 - 1/sin^2 θ / (1 + 1/sin θ)
= 1 - sin^2 θ / (sin θ + 1)
= (sin θ - sin^2 θ) / (sin θ + 1)
Simplify 1+csc θ as follows:
1 + csc θ = (1 + csc θ)(1 - csc θ) / (1 - csc θ)
= 1 - csc^2 θ / (1 - csc θ)
= 1 - 1/sin^2 θ / (1 - 1/sin θ)
= 1 - sin^2 θ / (sin θ - 1)
= (sin θ + sin^2 θ) / (sin θ - 1)
Substitute the above simplifications in the expression cos θ/(1-csc θ) * 1+csc θ/(1+ csc θ) to get:
cos θ / (sin θ - sin^2 θ) * (sin θ + sin^2 θ) / (sin θ + 1)
Simplify the expression by canceling out the sin^2 θ terms:
cos θ / (sin θ - sin^2 θ) * (sin θ + sin^2 θ) / (sin θ + 1)
= cos θ / (sin θ - sin^2 θ) * (1 + sin θ) / (sin θ + 1)
Simplify further by factoring out common terms in the numerator and denominator:
cos θ / (sin θ - sin^2 θ) * (1 + sin θ) / (sin θ + 1)
= cos θ * (1 + sin θ) / [(sin θ - sin^2 θ) * (sin θ + 1)]
Finally, simplify the expression by factoring out a sin θ term from the denominator:
cos θ * (1 + sin θ) / [(sin θ - sin^2 θ) * (sin θ + 1)]
= cos θ * (1 + sin θ) / [sin θ * (1 - sin θ) * (sin θ + 1)]
= cos θ / [sin θ * (1 - sin θ)] * (1 + sin θ)

During a walk a thon,noahs time in hours was,t,and distance in miles,d,are related by the equation 1/3d=t .A gragh of the equarion includes points (12,4)
Question:
During a walk-a-thon, Noah's time in hours was t, and distance in miles, d, are related by the equation \(\frac{1}{3}d = t\). A graph of the equation includes points (12,4).
1. Identify the independent variable.
2. What does the point (12,4) represent in this situation?
3. What point would represent the time it took to walk \(7\frac{1}{2}\) miles?
Answer:
(a) d
(b) He spent 4 hours to walk 12 miles
(c) \((7\frac{1}{2},2\frac{1}{2})\)
Step-by-step explanation:
Given
\(t = \frac{1}{3}d\)
Solving (a): The independent variable
The independent variable, in this problem is the distance walked. Because the distance walked stands alone, and it is when the distance is known, that the time spent is known.
Hence:
The independent variable is distance (d)
Solving (b): What (12, 4) represents
This implies that:
\(distance = 12\)
\(time\ spent = 4\)
So: He spent 4 hours to walk 12 miles
Solving (c): Point to represent the time to walk \(7\frac{1}{2}\) miles
This implies that:
\(d = 7\frac{1}{2}\)
Substitute \(d = 7\frac{1}{2}\) in \(t = \frac{1}{3}d\)
\(t = \frac{1}{3} * 7\frac{1}{2}\)
Express as improper fraction
\(t = \frac{1}{3} * \frac{15}{2}\)
\(t = \frac{5}{2}\)
Express as mixed number
\(t = 2\frac{1}{2}\)
So: The point is, \((7\frac{1}{2},2\frac{1}{2})\)

A 2-pound bag of carrots costs $7.68. What is the price per ounce?
The price of carrots per ounce is $0.24 .
Ounce is an unit of mass in the Imperial System. It is widely used throughout the world and is one of the oldest units of measurement to still exist. The unit ounce is derived from uncia, a unit of measurement in roman times.
The ounce(abbreviated oz) is equal to approximately 28.35 grams and 16 ounces make up a pound.
Now it is given that a 2-pound bag of carrots cost $7.68 .
Therefore price per pound of carrots=$7.68÷2
Price per pound=$ 3.84 .
Now we know that 16 ounces make up a pound.
Price of carrots per ounce= $3.84 ÷16
Price per ounce= $ 0.24
Therefore the price of carrots per ounce is $0.24

After translation, M would be at (-2.2), N would be at (-2,-1), and O would be at (-4,-1).
Explanation:
To get you started, as it isn't too difficult, the first thing that you should do is write down the coordinates for each point.
As an example, I'll use point O which is located at (2,3).
The translation is [-6, -4], which simply means to translate your x-value left 6(as it is negative) and your y-value down 4.
In the case of O(2,3), your translated point would be at (-4,-1).

We have,
Statistical significance is determined by the p-value, which measures the probability of obtaining the observed results if the null hypothesis (no difference between groups) is true.
A small treatment effect may still produce a low p-value if the sample size is large enough to detect even small differences.

Explain why if a symmetric matrix is diagonalizable then we can find an eigenbasis consisting entirely of orthonormal vectors.
If a symmetric matrix can be inverted into a diagonal matrix using another matrix, then it is diagonalizable. Accordingly, it may be said that there is a matrix P that can be inverted such that P-1 * A * P = D, where D is a diagonal matrix and A is the symmetric matrix. The diagonal entries of D are the appropriate eigenvalues, while the columns of P are the eigenvectors of A.
The matrix P is the foundation of the vector space because its columns are linearly independent and it is invertible. The inner product of any two different eigenvectors is 0, as A's eigenvectors are orthogonal to one another due to its symmetry.
We can divide each eigenvector by its norm to get an orthonormal basis from this collection of eigenvectors. As a result, a group of eigenvectors that are orthonormal to one another and serve as the vector space's orthonormal basis are produced.
Therefore, A symmetric matrix is diagonalizable and has an orthonormal eigen basis consisting of orthonormal eigenvectors, which can be obtained by dividing each eigenvector by its norm.

is Average velocity equation rearranged to find the area under the curve?
Yes, the equation of velocity is rearranged to find the area under the curve.
The equation of velocity in general is v = d/t
where v = velocity, d = distance, and t = time.
We rearrange this equation to create an equation for distance and the equation of distance determines the area under the curve.
Our motive is to isolate the variable whose equation we want to create. So, in this case, isolate 'd' and move all other variables to the other side.
1. Multiply both sides by t
v × t = d/t × t
2. Cancel the t where appropriate
v × t = d
3. We get the equation for d
d = v × t
Now, this equation is used to find the area under the curve.

the quality assurance department selected 12 samples of 100 printed circuit boards and tested them. the number of defective printed circuit boards in each sample was 3, 3, 0, 5, 1, 1, 5, 6, 6, 2, 0, and 1. what kind of control chart should be constructed to monitor the process?
Where 12 samples of 100 printed circuit boards were tested and the number of defective boards in each sample is provided, a control chart that should be constructed to monitor the process is the p-chart.
The p-chart, also known as the proportion chart, is used to monitor the proportion of nonconforming items in a sample. In this case, the number of defective printed circuit boards in each sample can be used to calculate the proportion of defective boards.
To construct the p-chart, you would calculate the proportion of defective boards for each sample by dividing the number of defective boards by the total number of boards in that sample. Then, you can plot these proportions on the control chart to monitor the process over time.
The p-chart helps to identify any shifts or trends in the proportion of defective boards, allowing the quality assurance department to take appropriate actions to maintain or improve the process quality.
