end
This code will produce the following four plots:
As you can see, the distribution of balls becomes more uniform as the number of balls increases. This is because the probability of a ball landing in a particular urn is proportional to the number of balls already in that urn.
When the number of balls is small, the distribution is not very uniform, but as the number of balls increases, the distribution approaches a uniform distribution.

When the variances of the population distribution and the sampling distribution of means are compared, the:
A. variances have the same degrees of freedom.
B. population variance is larger than the sampling distribution variance.
C. population variance is smaller than the sampling distribution variance.
D. variances are equal.
Answers
The variance of the sampling distribution of means, on the other hand, is equal to the variance of all possible sample means of the same size taken from the population.
Since a sample size is always less than the population size, the variance of the population distribution is greater than the variance of the sampling distribution of means.
Therefore, option B is correct.
The probability of selecting one data value less than 190 IS (C)31%
When the variances of the population distribution and the sampling distribution of means are compared, the (B) population variance is larger than the sampling distribution variance.
The probability of selecting one data value less than 190 given the mean and standard deviation of a population of 200 and 20 respectively is 31% (option C).
Solution: Given,
mean (μ) = 200,
standard deviation (σ) = 20
We need to find the probability of selecting one data value less than 190.
P(x < 190) = ?
Z = (X - μ)/σ
Taking X = 190,
Z = (190 - 200)/20
= -0.5
From the standard normal table, the probability of
Z = -0.5 is 0.3085
Therefore,
P(x < 190) = P(Z < -0.5)
= 0.3085
= 31%
Hence, option C is correct.
When the variances of the population distribution and the sampling distribution of means are compared, the population variance is larger than the sampling distribution variance.
This can be explained as follows;
The population distribution is the distribution of an entire population, while the sampling distribution of the mean is the distribution of the means of all possible samples of a specific size drawn from that population.
The variance of the population distribution is equal to the variance of a single observation of the population.

Three companies, A, B and C, make computer hard drives. The proportion of hard drives that fail within one year is 0.001 for company A, 0.002 for company B and 0.005 for company C. A computer manufacturer gets 50% of their hard drives from company A, 30% from company B and 20% from company C. The computer manufacturer installs one hard drive into each computer.
(a) What is the probability that a randomly chosen computer purchased from this manufacturer will experience a hard drive failure within one year? [4 marks]
(b) I buy a computer that does experience a hard drive failure within one year. What is the probability that the hard drive was manufactured by company C? [4 marks]
Answers
(a) The probability of the chosen hard drive to fail within one year is 0.005.
(b) The probability that the hard drive was manufactured by company C is 3.95%.
(a) The probability that a randomly chosen computer purchased from this manufacturer will experience a hard drive failure within one year is:
Probability of choosing hard drive from company A and failure within one year + Probability of choosing hard drive from company B and failure within one year + Probability of choosing hard drive from company C and failure within one year
P(A and F) = P(A) x P(F|A) = 0.5 x 0.001 = 0.0005
P(B and F) = P(B) x P(F|B) = 0.3 x 0.002 = 0.0006
P(C and F) = P(C) x P(F|C) = 0.2 x 0.005 = 0.0010
The probability that a randomly chosen computer purchased from this manufacturer will experience a hard drive failure within one year is:
0.0005 + 0.0006 + 0.0010 = 0.0021 (or 0.21%)
(b) Let F be the event that the hard drive fails within one year and C be the event that the hard drive is manufactured by company C.
We want to calculate P(C|F), the probability that the hard drive was manufactured by company C, given that it failed within one year;
P(C|F) = P(C and F) / P(F) = [P(C) x P(F|C)] / [P(A) x P(F|A) + P(B) x P(F|B) + P(C) x P(F|C)]
P(C|F) = (0.2 x 0.005) / (0.5 x 0.001 + 0.3 x 0.002 + 0.2 x 0.005)
P(C|F) = 0.083 / 0.0021 = 0.0395 (or 3.95%)

The probability that the hard drive in my computer is manufactured by company C given that my computer experiences a hard drive failure within one year is approximately 0.74.
(a) Let the random variable X denote the number of hard drives in the computer manufacturer's hard drives that fail within one year. The probability distribution of X can be found as follows:
[tex]P(X = 0) = 0.5(1 - 0.001) + 0.3(1 - 0.002) + 0.2(1 - 0.005) = 0.9957[/tex]
[tex]P(X = 1) = 0.5(0.001) + 0.3(0.002) + 0.2(0.005) = 0.0016[/tex]
Thus, the probability that a randomly chosen computer purchased from this manufacturer will experience a hard drive failure within one year is 0.0016.
(b) Let the event H denote that the computer I buy experiences a hard drive failure within one year. Let the event Ci denote that the hard drive in my computer is manufactured by company
i. Then, using Bayes' theorem, we have:
[tex]P(C3 | H) = P(H | C3)P(C3) / P(H)[/tex]
We can find the values of the three probabilities in the above formula as follows:
P(H | C1) = 0.001
P(H | C2) = 0.002
P(H | C3) = 0.005
P(C1) = 0.5
P(C2) = 0.3
P(C3) = 0.2
[tex]P(H) = P(H | C1)P(C1) + P(H | C2)P(C2) + P(H | C3)P(C3)≈ 0.00135[/tex]
Thus, P(C3 | H) = 0.005(0.2) / 0.00135 ≈ 0.74
Therefore, the probability that the hard drive in my computer is manufactured by company C given that my computer experiences a hard drive failure within one year is approximately 0.74.

8. center: (-7,5)

Step-by-step explanation:
8. to find the center, you need to get the equation in the form of (x-h)^2+(y-k)^2=r^2
you can do this by completing the square:
x^2+y^2+14x-10y-7=0
x^2+14x+49+y^2-10y+25=7+49+25
(x+7)^2+(y-5)^2=81

Two spheres A and B of mass 7.5 kg and 6.3 kg respectively are separated by a distance of 0.59 m. Calculate the magnitude of the gravitational force A exerts on B and B exerts on A. force A exerts on B force B exerts on A If the force between the spheres is now 3.50 times 10-9 N, how far apart are their centers?
Answers
To calculate the magnitude of the gravitational force A exerts on B and B exerts on A, we can use Newton's law of universal gravitation:
[tex]F = (G * m1 * m2) / r^2[/tex]
where F is the gravitational force, G is the gravitational constant (approximately [tex]6.67430 *10^-11 N m^2 / kg^2)[/tex], m1 and m2 are the masses of the two spheres, and r is the distance between their centers.
For the force A exerts on B:
[tex]F_AB = (G * m_A * m_B) / r^2[/tex]
Substituting the given values: m_A = 7.5 kg, m_B = 6.3 kg, and r = 0.59 m:
F_AB = (6.67430 × 10^-11 N m^2 / kg^2) * (7.5 kg) * (6.3 kg) / (0.59 m)^2
Calculating the above expression gives the magnitude of the gravitational force A exerts on B.
For the force B exerts on A, we use the same formula:
[tex]F_BA = (G * m_A * m_B) / r^2[/tex]
Substituting the given values: m_A = 7.5 kg, m_B = 6.3 kg, and r = 0.59 m:
[tex]F_BA = (6.67430 * 10^-11 N m^2 / kg^2) * (6.3 kg) * (7.5 kg) / (0.59 m)^2[/tex]
Calculating the above expression gives the magnitude of the gravitational force B exerts on A.
To find the distance between the centers of the spheres when the force between them is 3.50 times 10^-9 N, we rearrange the formula to solve for r:
r = √((G * m_A * m_B) / F)
Substituting the given values: m_A = 7.5 kg, m_B = 6.3 kg, and F = 3.50 × 10^-9 N:
r = √[tex]((6.67430 * 10^-11 N m^2 / kg^2) * (7.5 kg) * (6.3 kg) / (3.50 *10^-9 N))[/tex]
Calculating the above expression gives the distance between the centers of the spheres.

Scuba tanks arrive at a pressure test station for testing prior to shipment. The arrival rate is 16mins and the station test time averages 8 minutes per tank. Poisson distributions are assumed
A. What is the utilization of the test station?
B. What is the probability that a tank have to wait in the queue prior to testing?
C. What is the mean time a tank will spend in queue?
D. What is the mean time that a tank will spend in the system ?
E. What is the mean number of tanks that might be expected to be in queue at any time?
F. What is the mean number of tanks that might be expected to be in the system at any time ?
G. What is the probability of finding four or more tanks in the system at any time ?
H. Find the probability of 6 or more in the system
Answers
The probability of finding four or more tanks in the system at any time is approximately 0.95. The probability of having 6 or more tanks in the system is approximately 0.77.
A. The utilization of the test station is calculated by dividing the average service rate (1 tank per 8 minutes) by the arrival rate (1 tank every 16 minutes). Utilization = Service rate / Arrival rate = 1/2 = 0.5 or 50%.
B. The probability that a tank has to wait in the queue prior to testing can be calculated using the queuing theory formula for the M/M/1 queue. In this case, the utilization (ρ) is 0.5. The formula for the probability of waiting in the queue (Pw) is Pw = ρ^2 / (1 - ρ) = 0.5^2 / (1 - 0.5) = 0.25 / 0.5 = 0.5 or 50%.
C. The mean time a tank spends in the queue can be calculated using Little's Law, which states that the mean number of customers in a stable system (L) is equal to the arrival rate (λ) multiplied by the mean time spent in the system (W). In this case, L = λ * W. The mean number of tanks in the queue (Lq) can be calculated using Lq = λ * Wq, where Wq is the mean time spent in the queue. Given λ = 1/16 tanks per minute and Lq = 8 tanks, we can rearrange the equation to solve for Wq: Wq = Lq / λ = 8 / (1/16) = 128 minutes / 16 = 8 minutes.
D. The mean time a tank spends in the system (queue + test) is equal to the mean time spent in the queue (Wq) plus the mean service time (1/8 tanks per minute). Therefore, the mean time in the system (Ws) is Ws = Wq + 1/μ = 8 + 1/8 = 8.125 minutes.
E. The mean number of tanks expected to be in the queue at any time can be calculated using Little's Law: Lq = λ * Wq. Given λ = 1/16 tanks per minute and Wq = 8 minutes, we can calculate Lq: Lq = (1/16) * 8 = 0.5 tanks.
F. The mean number of tanks expected to be in the system at any time can be calculated using Little's Law: L = λ * Ws. Given λ = 1/16 tanks per minute and Ws = 8.125 minutes, we can calculate L: L = (1/16) * 8.125 = 0.507 tanks.
G. The probability of finding four or more tanks in the system at any time can be calculated using the Poisson distribution formula. By summing the probabilities for four, five, and more tanks, we get 0.043.
H. The probability of having 6 or more tanks in the system can also be calculated using the Poisson distribution formula, which results in a probability of 0.002.

let y=f(x) be the particular solution to the differential equation dydx=ex−1ey with the initial condition f(1)=0 . what is the value of f(−2) ?
Answers
To find the value of f(-2) given the differential equation dy/dx = e^(x-1) * e^y with the initial condition f(1) = 0, we can use separation of variables and solve the differential equation.
Starting with the given differential equation:
dy/dx = e^(x-1) * e^y
Separating variables by multiplying both sides by dx and e^(-y):
e^(-y) dy = e^(x-1) dx
Now, we can integrate both sides of the equation:
∫ e^(-y) dy = ∫ e^(x-1) dx
Integrating the left side with respect to y and the right side with respect to x:
e^(-y) = e^(x-1) + C
Applying the initial condition f(1) = 0, where x = 1 and f(1) = 0:
e^(-0) = e^(1-1) + C
1 = 1 + C
C = -2
Substituting the value of C back into the equation:
e^(-y) = e^(x-1) - 2
Now, we can find the value of f(-2) by substituting x = -2 into the equation:
e^(-y) = e^(-2-1) - 2
e^(-y) = e^(-3) - 2
To find the value of f(-2), we need to solve for y:
e^(-y) = 2 - e^(-3)
y = -ln(2 - e^(-3))
Therefore, the value of f(-2) is f(-2) = -ln(2 - e^(-3)).

Find the Surface area of the following figure below
Answers
Answer:

Step-by-step explanation:
Base area = 11*11 = 121
Lateral area = (11*4)*17/2 = 11*2*17 = 374
121+374=495
Triangle area is A = 1/2*B*H (B meaning base and h meaning height)
Rectangle area is A = L * W (L meaning length and W meaning width)
So the you have triangles with a base of 11 and height of 17 so 11*17*(1/2). That value times 4 because there are 4 of them so you get. 374 meters^2
Then you have the rectangle which is 11*11 so 121 add that to 374 and you get 495 meters^2 so the surface area is 495 meters^2 if I did it correctly.

The equation [tex](sin(x)cos(x))^2 = sin(2x)[/tex] is verified to be an identity.
Simplify LHS and RHS?
To verify whether the equation [tex](sin(x)cos(x))^2 = sin(2x)[/tex] is an identity, we can simplify both sides of the equation and see if they are equivalent.
Starting with the left side of the equation:
[tex](sin(x)cos(x))^2 = (sin(x))^2(cos(x))^2[/tex]
Now, we can use the trigonometric identity [tex]sin(2x) = 2sin(x)cos(x)[/tex] to rewrite the right side of the equation:
[tex]sin(2x) = 2sin(x)cos(x)[/tex]
Substituting this into the equation, we have:
[tex](sin(x))^2(cos(x))^2 = (2sin(x)cos(x))[/tex]
Next, we can simplify the left side of the equation:
[tex](sin(x))^2(cos(x))^2 = (sin(x))^2(cos(x))^2[/tex]
Since both sides of the equation are identical, we can conclude that the given equation is indeed an identity:
[tex](sin(x)cos(x))^2 = sin(2x)[/tex]
Hence, the equation [tex](sin(x)cos(x))^2 = sin(2x)[/tex] is verified to be an identity.

Find two negative consecutive integers such that the square of the first is five more than the second. Find the integers.
Answers
Answer:
the two consecutive negative integers are -2 and -1.
Step-by-step explanation:
Represent these negative integers by m and n.
Then (because the integers are consecutive) n = m + 1, and m^2 = n + 5.
Substituting m + 1 for n in the second equation, we get:
m^2 = m + 1 + 5, or
m^2 - m - 6 = 0
This factors into (m - 3)(m + 2) = 0. The only negative root is -2.
Thus, the two consecutive negative integers are -2 and -1.
Check: Is the square of the first five more than the second?
Is (-2)^2 = -1 + 5? YES
