A village in alaska is sometimes visited by polar bears. In fact, bear visits form a poisson process of rate 1 visits per month. At each visit a group of bears shows up; the size of a group is equal to 1,2, or 3 with equa

Answers

Answer 1

The probability for the bear visits using Poisson process of rate one visits per month is given by ,

P(X=i, Y=j) j=i                            j=2i                                        j=3i

X=i              e^(-1)(1/ i!) × 1/3^i 1/3^i + 4/3^(i-1) × e^(-1)/i!     2/3^i× e^(-1)/i!

Bear visits form a Poisson process of rate 1 visit per month.

Number of visits in a month  = Poisson distribution with parameter λ = 1.

Let X be the number of visits in a month.

And Y be the total number of bears in the month.

Probability of X and Y is equal to ,

P(X = i, Y = j), for i = 0, 1, 2, 3 and j = i, 2i, or 3i.

Law of total probability for  P(X = i, Y = j) for each i and j.

P(X = i, Y = i)

= P(X = i) × P(Y = i | X = i)

= e^(-λ) × λ^i / i! × 1/3^i

= e^(-1) × 1^i / i! × 1/3^i

= e^(-1) (1/ i!) × 1/3^i

Now,

P(X = i, Y = 2i)

= P(X = i) × P(Y = 2i | X = i)

= e^(-λ) × ( λ^i / i!) ×  [(1/3)^i + 2(1/3)^(i-1)(2/3)]

= e^(-1) / i! × [1/3^i + 4/3^i-1]

For,

P(X = i, Y = 3i)

= P(X = i) × P(Y = 3i | X = i)

= e^(-λ) × λ^i / i! × (1/3)^i × 2

= 2e^(-1) / i! × 1/3^i

Therefore, the probability of the size of bears for given condition is equal to,

P(X=i, Y=j) j=i                            j=2i                                        j=3i

X=i              e^(-1)(1/ i!) × 1/3^i 1/3^i + 4/3^(i-1) × e^(-1)/i!     2/3^i× e^(-1)/i!

real zero, Including any repeated zeroes? Choose your answ f(x)=x^(6)+8x^(5)+9x^(4)-2x^(2)-7x+4

Answers

The real zeroes of the function f(x)=x^(6)+8x^(5)+9x^(4)-2x^(2)-7x+4 are -4, -1, and 1.

The real zeroes of the function f(x)=x^(6)+8x^(5)+9x^(4)-2x^(2)-7x+4 can be found by using the Rational Zero Theorem and synthetic division.

The Rational Zero Theorem states that the possible rational zeroes of a polynomial are the factors of the constant term divided by the factors of the leading coefficient. In this case, the constant term is 4 and the leading coefficient is 1, so the possible rational zeroes are ±1, ±2, and ±4.

We can use synthetic division to test these possible zeroes and find the actual zeroes of the function. Synthetic division is a method of dividing a polynomial by a linear factor of the form x-a. The result of synthetic division is a quotient and a remainder, and if the remainder is 0, then x-a is a factor of the polynomial and a is a zero of the function.

Using synthetic division, we find that the real zeroes of the function are -4, -1, and 1. These are the values of x that make the function equal to 0. There are no repeated zeroes in this case.

Fluffy, Spot, and Shampy have a combined age in dog years of 82. Spot is 14 years younger than Fluffy. Shampy is 6 years older than Fluffy. What is Fluffy's age, f, in dog years?

Answers

The age of fluffy is 30 in dog years. The solution has been obtained by using linear equation.

What is a linear equation?

One is the degree of the linear equation. The absence of variables in linear equations with exponents greater than one is obvious. The graph's equation results in a straight line.

We are given that combined age of 3 dogs in dog years is 82.

Let Fluffy's age be 'f'.

Age of Spot = (f - 14)

Age of Shampy = (f + 6)

From this, we get

f + (f - 14) + (f + 6) = 82

On solving this, we get

⇒f + f - 14 + f + 6 = 82

⇒3f - 8 = 82

⇒3f = 90

⇒f = 30

Hence, the age of fluffy is 30 in dog years.

Answers

The probability of both events A and B occurring is 0.3 or 30%.

The cumulative distribution function of X is F(x) = 17 * ln(x + 1) for x > 0.

The probability of event B occurring given that event A does not occur is 0.125 or 12.5%.

ANSWER 4:
We can use the formula P(AB) = P(A) * P(B|A) to find the probability of both events A and B occurring.
P(AB) = P(A) * P(B|A)
P(AB) = 0.5 * 0.6
P(AB) = 0.3
So the probability of both events A and B occurring is 0.3 or 30%.

ANSWER 5:
We can use the formula P(B|A) = P(AB) / P(A) to find the probability of event B occurring given that event A does not occur. We can also use the formula P(A') = 1 - P(A) to find the probability of event A not occurring.
P(A') = 1 - P(A)
P(A') = 1 - 0.2
P(A') = 0.8
P(B|A') = P(BA') / P(A')
P(B|A') = 0.1 / 0.8
P(B|A') = 0.125
So the probability of event B occurring given that event A does not occur is 0.125 or 12.5%.

ANSWER 6:
The cumulative distribution function (CDF) of a continuous random variable X is defined as F(x) = P(X <= x). To find the CDF of X, we need to integrate the probability density function (PDF) of X from 0 to x.
F(x) = ∫ f(t) dt from 0 to x
F(x) = ∫ (17/(t + 1)) dt from 0 to x
F(x) = 17 * ln(t + 1) from 0 to x
F(x) = 17 * ln(x + 1) - 17 * ln(0 + 1)
F(x) = 17 * ln(x + 1)
So the cumulative distribution function of X is F(x) = 17 * ln(x + 1) for x > 0.

The distance between any point on the parabola and the directrix is equal to the distance between that point and the focus. This property is what defines a parabola.

How to draw a parabola when given the directix and focus​?

To draw a parabola given the directrix and focus, follow these steps:

Draw the directrix as a straight line.Mark the focus point on the opposite side of the directrix from the vertex.Find the midpoint between the focus and the directrix, which is also the vertex of the parabola.,Draw a perpendicular line from the vertex to the directrix. This is the axis of symmetry of the parabola.Measure the distance between the focus and the vertex. This distance is called the focal length and is denoted by "p".From the vertex, mark a point "p" units above and below the vertex along the axis of symmetry. These points are called the "endpoints of the latus rectum."Draw lines through each endpoint of the latus rectum perpendicular to the axis of symmetry, extending to intersect the directrix. These two lines will be parallel to each other and equidistant from the axis of symmetry.Finally, draw a smooth curve through the focus point that passes through each endpoint of the latus rectum.

Now, let's look at the given choices to find the best proof for Gemma's conjecture.

Choice B) Let 2n + 1 be an odd number; (2n + 1) + (2n + 1) = 4n + 2. Because 4(n + 2) is divisible by 2, the sum of 2n + 1 and itself is even.

This choice provides a proof by using algebraic equations. It begins by defining an odd integer as 2n + 1, where n is any integer. Then, it uses algebraic manipulation to show that the sum of this odd integer and itself results in an even integer. Specifically, (2n + 1) + (2n + 1) simplifies to 4n + 2, which is equal to 2(2n + 1). This proves that the sum of an odd integer and itself is always even.

The yearly income of a family is Rs. 500000. The ratio of the expenditure and saving of the family is 4 : 1. Find the amount of expenditure and saving.​

Answers

Answer:

Let's assume that the amount of saving is x.

According to the problem, the ratio of expenditure to saving is 4:1, so the amount of expenditure can be expressed as 4x.

The total income of the family is Rs. 500000, and it can be expressed as the sum of expenditure and saving:

Expenditure + Saving = 500000

Substituting the values of expenditure and saving, we get:

4x + x = 500000

Simplifying this equation, we get:

5x = 500000

Dividing both sides by 5, we get:

x = 100000

Therefore, the amount of saving is Rs. 100000, and the amount of expenditure is 4 times this value, which is Rs. 400000.

D) If the testing in (c) continues for only 600 more hours, what is the expected number
of failures?

Answers

AMSAA growth model

The MTTF at the conclusion of the test cycle is 232.59 hours. 22423.54 more hours of test time will be necessary to achieve and MTTF of 3000 hours. 52.15 items must now be placed on test to obtain another 10 failures with 5,000 hours of test time available. If the testing continues for only 600 more hours, 1.75 is the expected number of failures.

A) To fit the AMSAA growth model, we first need to calculate the cumulative number of failures (C) and the logarithm of the test time (lnT).

| Test Time (T) | C | lnT |
|---------------|---|-----|
| 28            | 1 | 3.33|
| 146           | 2 | 4.98|
| 258           | 3 | 5.55|
| 426           | 4 | 6.05|
| 521           | 5 | 6.26|
| 1027          | 6 | 6.93|
| 1273          | 7 | 7.15|

Next, we can use linear regression to estimate the parameters of the AMSAA model, β and η:

C = βlnT - η

Using linear regression, we get β = 1.11 and η = 3.82.

To estimate the MTTF at the conclusion of the test cycle, we can use the formula:

MTTF = (T/C)^(1/β)

Plugging in the values for T (1273), C (7), and β (1.11), we get:

MTTF = (1273/7)^(1/1.11) = 232.59 hours



B) To achieve an MTTF of 3000 hours, we need to solve for T in the equation: 3000 = (T/C)^(1/β)

Plugging in the values for C (7), β (1.11), and rearranging the equation, we get:

T = 3000^(β) * C = 3000^(1.11) * 7 = 23696.54 hours

Since we have already tested for 1273 hours, we need an additional 23696.54 - 1273 = 22423.54 hours of test time to achieve an MTTF of 3000 hours.



C) To obtain another 10 failures with 5000 hours of test time available, we can use the formula:

C = βlnT - η

Plugging in the values for C (10), β (1.11), η (3.82), and T (5000), and rearranging the equation, we get:

10 = 1.11ln(5000) - 3.82

ln(5000) = (10 + 3.82)/1.11 = 12.47

5000 = e^(12.47) = 260753.13

Therefore, we need to place 260753.13/5000 = 52.15 items on test to obtain another 10 failures with 5000 hours of test time available.



D) If the testing in (c) continues for only 600 more hours, we can use the formula:

C = βlnT - η

Plugging in the values for β (1.11), η (3.82), and T (600), and rearranging the equation, we get:

C = 1.11ln(600) - 3.82 = 1.75

Therefore, the expected number of failures in 600 more hours of testing is 1.75.

Since it is isosceles, opposite sides for 45° angles are same.

Other leg = 6 feet, which is the height.

Area of the trapezoid = 1/2 (a + b)h, where a and b are bases and h is the height.

A = 1/2 (10 + 16) 6

   = 78 feet²

Hence the correct option is b.

In his​ motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing​ spot, a distance of 90 ​mi, in 3 hr.​ Returning, he finds that the trip​ downstream, still at top​ speed, takes only 2.5 hr. Find the rate of​ Bill's boat and the speed of the current. Let x​ = the rate of the boat in still water and y​ = the rate of the current.

Answers

The rate of Bill's boat in still water is 33 mph and the speed of the current is 3 mph.

To find the rate of Bill's boat and the speed of the current, we can use the distance formula, which states that distance = rate × time. Since we know the distance and time for both the upstream and downstream trips, we can set up two equations and solve for the rate of the boat and the speed of the current.

Let x = the rate of the boat in still water and y = the rate of the current.

For the upstream trip:
90 = (x - y) × 3

For the downstream trip:
90 = (x + y) × 2.5

Simplifying the equations gives us:
90 = 3x - 3y
90 = 2.5x + 2.5y

Multiplying the first equation by 2.5 and the second equation by 3 gives us:
225 = 7.5x - 7.5y
270 = 7.5x + 7.5y

Adding the two equations together eliminates the y variable:
495 = 15x

Solving for x gives us:
x = 33

Substituting x back into the first equation gives us:
90 = (33 - y) × 3
90 = 99 - 3y
3y = 9
y = 3

(3 points) Problem 5: Determine the value(s) ofasuch that [1a​], [aa+2​] are linearly independent.

Answers

To determine the value(s) of a such that [1 a], [a a+2] are linearly independent, we need to find the values of a that make the determinant of the matrix non-zero. The determinant of a 2x2 matrix is given by:

|1 a|
|a a+2| = (1)(a+2) - (a)(a) = a + 2 - a^2

To make the determinant non-zero, we need to solve the equation:

a + 2 - a^2 ≠ 0

Rearranging the equation, we get:

a^2 - a - 2 ≠ 0

Factoring the equation, we get:

(a - 2)(a + 1) ≠ 0

Therefore, the values of a that make the determinant non-zero are a ≠ 2 and a ≠ -1. These are the values of a that make the vectors [1 a], [a a+2] linearly independent.

So, the value(s) of a such that [1 a], [a a+2] are linearly independent are a ≠ 2 and a ≠ -1.

Si al salario por semana se le rebaja el 9. 5% para ccss y el salario es de 50. 000 ¿cuánto me pagan?

Answers

If the weekly salary is reduced by 9.5% for CCSS and the salary is 50000, then they would pay $45250.

The percent reduction in the weekly salary is = 9.5% = 0.095,

So, the amount of the reduction is;

⇒ reduction = 9.5% of 50,000

⇒ reduction = 0.095 x 50,000

⇒ reduction = 4750

So, the reduction in the weekly salary is 4750,

Now, we subtract the reduction from the original salary to get the new salary after the reduction,

⇒ new salary = 50000 - 4750

⇒ new salary = 45250

Therefore, the new salary after the 9.5% reduction for CCSS is $45250.

The drama club at Hawthorne Middle School is selling tickets to their spring musical. Student tickets
cost $10 and adult tickets cost $15. Last week, they sold 120 tickets for the Sunday matinee show. If those
ticket sales totaled to $1,400, how many adult tickets were sold? How many student tickets were sold?

Answers

40 adult tickets were sold and 80 student tickets were sold.

What is an equation?

An equation is a mathematical statement that asserts that two expressions are equal. It typically consists of variables, constants, and mathematical operations.

Let's use algebra to solve this problem.

Let's call the number of student tickets sold "s" and the number of adult tickets sold "a".

From the problem, we know two things:

The total number of tickets sold was 120:

s + a = 120

The total amount of money made from ticket sales was $1,400:

10s + 15a = 1400

Now we have two equations with two variables, so we can solve for "a" and "s".

Let's start by solving for "s" in the first equation:

s + a = 120

s = 120 - a

Now we can substitute this expression for "s" into the second equation:

10s + 15a = 1400

10(120 - a) + 15a = 1400

1200 - 10a + 15a = 1400

5a = 200

a = 40

So 40 adult tickets were sold.

Now we can substitute this value of "a" into the first equation to find "s":

s + a = 120

s + 40 = 120

s = 80

So 80 student tickets were sold.

Therefore, 40 adult tickets were sold and 80 student tickets were sold.

Answers

The values of the variables x, y, and z obtained by using Cramer's rule are 83/105, -277/105, and -99/105, respectively.

To find the values of the variables x, y, and z using Cramer's rule, we need to find the determinant of the coefficient matrix and the determinants of the matrices obtained by replacing the first, second, and third columns of the coefficient matrix with the constant terms.
The coefficient matrix is:
|−3 0 −6|
| 8 −2 3|
| 2 −1 −4|
The determinant of the coefficient matrix is:
|−3 0 −6| = (−3)(−2)(−4) − (0)(3)(2) − (−6)(8)(−1) − (−3)(−1)(3) − (0)(−4)(8) − (−6)(−2)(2)
= −24 − 0 − 48 − 9 − 0 − 24
= −105
The matrix obtained by replacing the first column with the constant terms is:
|11 0 −6|
|17 −2 3|
| 3 −1 −4|
The determinant of this matrix is:
|11 0 −6| = (11)(−2)(−4) − (0)(3)(3) − (−6)(17)(−1) − (11)(−1)(3) − (0)(−4)(17) − (−6)(−2)(3)
= 88 − 0 − 102 − 33 − 0 − 36
= −83
The matrix obtained by replacing the second column with the constant terms is:
|−3 11 −6|
| 8 17 3|
| 2  3 −4|
The determinant of this matrix is:
|−3 11 −6| = (−3)(17)(−4) − (11)(3)(2) − (−6)(8)(3) − (−3)(3)(3) − (11)(−4)(2) − (−6)(17)(2)
= 204 − 66 − 144 − 9 + 88 + 204
= 277
The matrix obtained by replacing the third column with the constant terms is:
|−3 0 11|
| 8 −2 17|
| 2 −1  3|
The determinant of this matrix is:
|−3 0 11| = (−3)(−2)(3) − (0)(17)(2) − (11)(8)(−1) − (−3)(−1)(17) − (0)(3)(8) − (11)(−2)(2)
= 18 − 0 + 88 − 51 − 0 + 44
= 99
Now we can use Cramer's rule to find the values of the variables x, y, and z:
x = (−83)/(-105) = 83/105
y = (277)/(-105) = -277/105
z = (99)/(-105) = -99/105
83/105, -277/105, and -99/105 are the values of x,y and z respectively.

Keegan was asked to graph (R90•D2)(Triangle ABC). Explain Keegan’s error.

Answers

Keegan's error is that he did not provide enough information to fully determine the result of the given composition of transformations, namely (R90•D2)(Triangle ABC).

To be able to graph the image of Triangle ABC under the composition of R90 (a 90-degree counterclockwise rotation) and D2 (a dilation with center the origin and scale factor 2), we need to know the center of rotation for the rotation R90.

The reason for this is that the composition of a rotation and a dilation is not commutative, meaning that the order of the transformations matters. Specifically, the result of the composition depends on whether the dilation is applied before or after the rotation. If the dilation is applied before the rotation, then the center of dilation becomes the center of rotation for the rotation. If the rotation is applied before the dilation, then the center of dilation is not affected by the rotation.

Therefore, without knowing the center of rotation for the rotation R90, we cannot determine the exact result of the composition (R90•D2)(Triangle ABC), and thus we cannot graph it accurately.
