A bag of marbles contains 3 red marbles, 7 blue marbles, and 5 orange marbles. If a marble is drawn from the bag and not replaced, then a second marble is drawn. Calculate P(red then orange):
Answer:
\(\dfrac{1}{14}\).
Step-by-step explanation:
It is given that,
Red marbles = 3
Blue marbles = 7
Orange marbles = 5
Total marbles = 3+7+5 = 15
Probability of getting a red marble is
\(P(Red)=\dfrac{\text{Red marbles}}{\text{Total marbles}}\)
\(P(Red)=\dfrac{3}{15}\)
\(P(Red)=\dfrac{1}{5}\)
If a marble is drawn from the bag and not replaced. So remaining marbles is 15-1=14. Now,
Probability of getting an orange marble is
\(P(orange )=\dfrac{\text{Orange marbles}}{\text{Total remaining marbles}}\)
\(P(orange)=\dfrac{5}{14}\)
Now,
\(P(\text{red then orange})=P(Red)\times P(orange)\)
\(P(\text{red then orange})=\dfrac{1}{5}\times \dfrac{5}{14}\)
\(P(\text{red then orange})=\dfrac{1}{14}\)
Therefore, the required probability is \(\dfrac{1}{14}\).

In the past, the output of a process had a mean of 2.050 and a standard deviation of 0.020 liters. If a current sample of output had these values {2.038 2.054 2.053 2.055 2.059 2.059 2.009 2.042 2.053 2.047}, would that indicate that the process is still "in order" (as opposed to being "out of order")? What if the sample was {2.022 1.997 2.044 2.044 2.032 2.045 2.045 2.047 2.030 2.044}?
For the first sample {2.038 2.054 2.053 2.055 2.059 2.059 2.009 2.042 2.053 2.047}, the process is still "in order," while for the second sample {2.022 1.997 2.044 2.044 2.032 2.045 2.045 2.047 2.030 2.044}, the process might be "out of order."
To determine whether the process is still "in order" or "out of order," we can compare the current sample of output to the known mean and standard deviation of the process.
For the first sample {2.038 2.054 2.053 2.055 2.059 2.059 2.009 2.042 2.053 2.047}:
Calculate the sample mean by summing up all the values in the sample and dividing by the number of values (n = 10):
Sample mean = (2.038 + 2.054 + 2.053 + 2.055 + 2.059 + 2.059 + 2.009 + 2.042 + 2.053 + 2.047) / 10 = 2.048.
Compare the sample mean to the known process mean (2.050):
The sample mean (2.048) is very close to the process mean (2.050), indicating that the process is still "in order."
Calculate the sample standard deviation using the formula:
Sample standard deviation = sqrt(sum((x - mean)^2) / (n - 1))
Using the formula with the sample values, we find the sample standard deviation to be approximately 0.019 liters.
Compare the sample standard deviation to the known process standard deviation (0.020):
The sample standard deviation (0.019) is very close to the process standard deviation (0.020), further supporting that the process is still "in order."
For the second sample {2.022 1.997 2.044 2.044 2.032 2.045 2.045 2.047 2.030 2.044}:
Calculate the sample mean:
Sample mean = (2.022 + 1.997 + 2.044 + 2.044 + 2.032 + 2.045 + 2.045 + 2.047 + 2.030 + 2.044) / 10 ≈ 2.034
Compare the sample mean to the process mean (2.050):
The sample mean (2.034) is noticeably different from the process mean (2.050), indicating that the process might be "out of order."
Calculate the sample standard deviation:
The sample standard deviation is approximately 0.019 liters.
Compare the sample standard deviation to the process standard deviation (0.020):
The sample standard deviation (0.019) is similar to the process standard deviation (0.020), suggesting that the process is still "in order" in terms of variation.
In summary, for the first sample, the process is still "in order" as both the sample mean and sample standard deviation are close to the known process values.
However, for the second sample, the difference in the sample mean suggests that the process might be "out of order," even though the sample standard deviation remains within an acceptable range.

Find the distance between the points (2,0) and (-4,6)
Answer:

Step-by-step explanation:
We have this equation to find the distance between two points :
a = ( 2 , 0 ) and b = ( -4 , 6 )
\(distance = \sqrt{ {( \: y(b) - y(a) \: })^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ \)
Now just need to put the coordinates in the equation :
\(distance = \sqrt{ ({6 - 0})^{2} + ({ - 4 - 2})^{2} } \\ distance = \sqrt{ {6}^{2} + ({ - 6})^{2} } = \sqrt{36 + 36} \\ distance = \sqrt{36 \times 2} = 6 \sqrt{2} \)

A cylinder has base radius x cm and height 2x cm. A cone has base radius x cm and height h cm. The volume of the cylinder and the volume of the cone are equal. Find h in terms of x. Give your answer in its simplest form.
The value of h in terms of x when the volume of cylinder is equal to that of cone is h = 6x²
What is volume of cylinder and cone?Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface. The unit of volume is in cubic units such as m3, cm3, in3 etc. Sometimes, volume is also termed capacity.
The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together.
The volume of cylinder = πr²h
and volume of cone = 1/3 πr²h
since the volume of the cone and cylinder are equal
πr²h = 1/3 πr²h
r in cylinder = x cm and h is 2x
r in cone = x cm
therefore πx²×2x = 1/3πxh
divide both side by πx
π2x³/πx = h/3
2x² = h/3
therefore h = 3×2x²
h = 6x²
therefore the value of h in terms of x is h = 6x²

Rouche's theorem, f(z) and f(z) + g(z) have the same number of zeros inside the unit circle |z| = 1.
By using the quadratic formula we get,
\($$z=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \Right arrow z=\frac{-2\pm\sqrt{(-2)^2-4(4)(3)}}{2(4)}$$$$\Right arrow z=\frac{-2\pm i\sqrt{2}}{4}$$$$\Rightarrow z=\frac{-1\pm i\frac{\sqrt{2}}{2}}{2}$$\)These two zeros lie inside the unit circle |z| = 1. Let's now examine the function g(z) =\(x(9x^4 + x). Let f(z) = 3 + 2z + 4z^2\), then we have to show that \(|x(9x^4 + x)| < |3 + 2z + 4z^2| on |z| = 1\). Since |z| = 1, we can bound |2z| by 2 and |4z^2| by 4. Therefore we have,\($$|3+2z+4z^2|\geq |2z|-4+3=|2z|-1$$\)On the other hand, we have,\($$|x(9x^4+x)|\leq |9x^6+x^2|$$$$\leq 9|x|^6 + |x|^2$$$$=9|x|^2|x|^4+|x|^2$$$$\leq 9|x|^2 + |x|^2$$$$=10|x|^2$$$$\Right arrow |x(9x^4+x)| < 10$$\)Now we want to show that |2z| > 1.
To do so, we assume the opposite, i.e. |2z| ≤ 1, then we have,\($$|3+2z+4z^2|\leq 4+3+4=11$$\)
But we have just shown that \($|x(9x^4+x)| < 10$\), which means that for |2z| ≤ 1 we have,\($$|x(9x^4+x)| < |3+2z+4z^2|$$\)
Therefore, by Rouche's theorem, f(z) and f(z) + g(z) have the same number of zeros inside the unit circle |z| = 1.

Sonequa has two containers one in the shape of a cylinder and the other in the shape of a cone the two containers of equal radii and equal Heights she investigated the relationship between the volume of the cone and the cylinder by transferring water between the two containers which of the following claims is most likely to be supported using the result of sonequa investigation
Answer:35
Step-by-step explanation:
The volume of a cylinder is calculated by multiplying the area of its base by its height. The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height.
The volume of a cone is calculated by multiplying the area of its base by its height and then dividing by 3. The formula for the volume of a cone is V = (1/3)πr²h, where r is the radius of the base and h is the height.
Since Sonequa’s two containers have equal radii and equal heights, it can be concluded that the volume of the cylinder is three times the volume of the cone. This means that if Sonequa fills the cone with water and pours it into the cylinder, she will need to repeat this process three times to fill the cylinder completely.
So, the claim that is most likely to be supported using the result of Sonequa’s investigation is: “The volume of a cylinder with the same radius and height as a cone is three times greater than the volume of the cone.”

the estimated number of insects on earth is 1 x 10^19. the number of people on earth is currently is estimated to be 6 x 10^9. what is the number of insects per person THIS IS DUE TODAY!!
Based on the estimated numbers, there are approximately 1.67 billion insects per person on Earth.
To calculate the number of insects per person, we can divide the estimated number of insects on Earth by the estimated number of people on Earth.
The estimated number of insects on Earth is\(1 \times 10^{19.\)
The estimated number of people on Earth is \(6 \times 10^9.\)
To find the number of insects per person, we can divide the number of insects by the number of people:
Number of insects per person = (Number of insects) / (Number of people)
\(= (1 \times 10^19) / (6 \times 10^9)\)
To simplify this division, we can divide the coefficients and subtract the exponents of 10:
\(= (1 / 6) \times 10^{(19 - 9)\)
\(= (1 / 6) \times 10^{ 10\)
Therefore, the number of insects per person is approximately\((1/6) \times 10^{10.\)
This can be expressed as \(1.67 \times 10^9,\) in scientific notation.
So, based on the estimated numbers, there are approximately 1.67 billion insects per person on Earth.

Benny's arcade has five video game machines. The average time between failures (i.e. the average time between jobs) is 34 hours. The maintenance engineer can repair a machine in about 13 hours. Assume the failure time and repair times are both exponentially distributed. What is the average time in HOURS from when a machine breaks until it is fixed?
The average time in hours from when a machine breaks until it is fixed is approximately 11.3 hours.
Given,
Benny's arcade has five video game machines
The average time between failures = 34 hours
The maintenance engineer can repair a machine in about = 13 hours
The failure time and repair times are both exponentially distributed
The formula for the mean of an exponential distribution is mean = 1/λ where λ is the rate parameter of the distribution.
In this problem, the rate parameter of both the failure time and repair time is the reciprocal of their respective averages. Therefore,
λ_f = 1/34λ_r = 1/13
Now, let's find the average time from when a machine breaks until it is fixed using the fact that the sum of two independent exponential distributions with rate parameters λ1 and λ2 is itself an exponential distribution with rate parameter λ1+λ2.
So, the rate parameter for the time from when a machine breaks until it is fixed is λ_f+λ_r = 1/34+1/13
= 0.0885 hours⁻¹ (approximately)
Hence, the average time from when a machine breaks until it is fixed is mean = 1/λ= 1/0.0885 ≈ 11.3 hours (approximately).
Therefore, the average time in hours from when a machine breaks until it is fixed is approximately 11.3 hours.

The first box can be filled by adding up the two angles:
m∠L +m∠M = 42° +48° = 90°
You don't really have to go to that trouble, because you already know that the sum of the two acute angles in a right triangle is 90°. (They are complements of each other.)
__
Since no side lengths are given, you need to use your calculator to find the sines of these angles, if a numerical value is required. If a literal ratio is required, the mnemonic SOH CAH TOA reminds you that ...
Sin = Opposite/Hypotenuse
sin(L) = MN/LM = sin(42°) ≈ 0.66913
sin(M) = LN/LM = sin(48°) ≈ 0.74314
1. Kendra owns a restaurant. She charges $1. 50 for 2 eggs and one piece of toast, and $. 90 for one egg
and one piece of toast. Determine how much she charges for each egg and each piece of toast
Kendra cost $0.60 for each egg and $0.30 for each piece of toast.
Let's assume that the cost of one egg is x and the cost of one piece of toast is y.
From the given information, we can set up two equations:
2x + y = 1.5
x + y = 0.9
We can solve this system of equations by either substitution or elimination method.
Using the elimination method, we can multiply the second equation by -2 to eliminate y:
-2x - 2y = -1.8
2x + y = 1.5
Adding these two equations, we get:
-1y = -0.3
y = 0.3
Substituting y = 0.3 in either of the two equations, we get:
x = 0.6
Therefore, Kendra charges $0.60 for each egg and $0.30 for each piece of toast.
