The "number-of-ways" to assign 6 jobs to 4 employees so that every employee is assigned "at-least" one job is (c) 1560.

The total number of jobs is = 6 jobs,

The total number of employees is = 4 employee,

We know that, each employee gets at-least one job ,

So, there are 2 possibilities,

Case(i) : (3,1,1,1) , In this case one employee gets 3 job,

So, total number of ways is = ⁶C₃׳C₁ײC₁×¹C₁×(4!/3!) = 480 ways,

Case(ii) : (2,2,1,1) , In this case two employee get two jobs,

So, total number of ways is = ⁶C₂×⁴C₂ײC₁×¹C₁×(4!/2!×2!) = 1080,

On adding we get,

⇒ Total-Ways is = 480 + 1080 = 1560.

Therefore, the correct option is (c).

the value of the parameter λ is approximately 0.0346, and the probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value is about 75%.

To answer this question, we will first find the value of the parameter λ using the given standard deviation, and then calculate the probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value.

a. What is the value of the parameter λ?

The double exponential distribution has the following properties:

Mean = 0
Variance = 2/λ²
Standard Deviation = sqrt(Variance) = sqrt(2/λ²)

Given that the standard deviation is 40.9 km, we can set up the equation:

40.9 = sqrt(2/λ²)

Now, we will solve for λ:

(40.9)² = 2/λ²
1672.81 = 2/λ²
λ² = 2/1672.81
λ² = 0.001196
λ = sqrt(0.001196)
λ ≈ 0.0346

b. What is the probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value?

To find the probability, we need to integrate the density function f(x) over the interval (-40.9, 40.9):

P(-40.9 < X < 40.9) = ∫(-40.9 to 40.9) 0.5(0.0346)e^(-0.0346|x|) dx

By using the double exponential properties, we know that the probability of being within 1 standard deviation of the mean value is approximately 0.75 or 75%.

In summary, the value of the parameter λ is approximately 0.0346, and the probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value is about 75%.

The deck of cards contains a total of 29 cards, of which 15 are green. Therefore, the probability of picking a green card at random can be calculated by dividing the number of green cards by the total number of cards, giving:

P(green) = 15/29

This probability can also be expressed as a decimal or a percentage. As a decimal, it would be 0.5172, and as a percentage, it would be 51.72%. This means that there is a slightly higher than 50% chance of picking a green card at random from this deck.

It is important to note that this probability assumes that the deck is well-shuffled and that all cards have an equal chance of being picked. If the deck is not well-shuffled or if some cards are missing or duplicated, the probability of picking a green card would be affected.

b) The probability that he could be the father is equals the 0.0238.

We have an expert witness for a paternity lawsuit testifies that the length of a pregnancy is normally distributed. Let variable X has normal distribution, Mean, μ = 280 days

standard deviations, σ = 13 days

An alleged father was out of the country from 240 to 306 days before the birth of the child. So, the variable value varies X < 240 or X> 306. Using Z-Score formula for normal distribution,

[tex]z= \frac{x -μ}{σ}[/tex]

For x = 240

As per the details given, The curl of the vector field F is zero. The divergence of the vector field F is zero.

The vector calculus operators can be used to determine the curl and divergence of the vector field F(x, y, z) = yz(sin(xy))i - xz(sin(xy))j - cos(xy)k.

The cross product of the del operator () and the vector field F yields the curl of the vector field F:

∇ × F = ( ∂/∂x , ∂/∂y , ∂/∂z ) × ( Fx , Fy , Fz )

∂/∂x = ∂/∂y = ∂/∂z = 0

∇ × F = (0 , 0 , 0) × (yz(sin(xy)) , -xz(sin(xy)) , -cos(xy))

∇ × F = (0 , 0 , 0)

∇ · F = ( ∂/∂x , ∂/∂y , ∂/∂z ) · ( Fx , Fy , Fz )

The final answer is C3 is approximately 0.21, to 2 digits after the decimal.

To find C3, we need to use the fact that v is a linear combination of the basis vectors bi, b2, and b3, with coefficients C1, C2, and C3 respectively.

So we have:
v = C1bi + C2b2 + C3b3

Substituting the given values for v and the basis vectors, we get:
-1-1 = C1(1/√2) + C2(-1) + C3(0)

Simplifying, we get:
C1/√2 - C2 = 1

To solve for C3, we need to use the fact that the basis vectors are orthonormal, which means they are pairwise orthogonal (i.e. perpendicular) and have unit length.

In particular, this means that:
bi · b3 = 0
b2 · b3 = 0
bi · bi = 1
b2 · b2 = 1
b3 · b3 = 1

Using the given values for the basis vectors, we can compute the dot products:
bi · b3 = 1/√2 * 0 - 1 * 1/2 + 0 * (-1/2) = -1/2
b2 · b3 = (-1) * 0 + 0 * (-1/2) + 0 * (1/2) = 0
bi · bi = 1/√2 * 1/√2 + (-1) * (-1) + 0 * 0 = 1
b2 · b2 = (-1) * (-1) + 0 * 0 + 0 * 0 = 1
b3 · b3 = 0 * 0 + 0 * 0 + 1 * 1 = 1

Now we can use the fact that the dot product of two vectors is related to their projection onto each other. Specifically, if u and v are vectors, then:
u · v = |u| * |v| * cos(theta)

where |u| and |v| are the lengths of u and v, and theta is the angle between them.

In our case, we can use the dot product of bi and b3 to compute the projection of v onto the b3 direction.

We have:
v · b3 = (-1-1) * 0 = 0

But we also know that:
v · b3 = C1 * (bi · b3) + C2 * (b2 · b3) + C3 * (b3 · b3)

Substituting the dot products we computed earlier, we get:
0 = -1/2 * C1 + 0 * C2 + 1 * C3

Simplifying, we get:
C3 = 1/2 * C1

We can now substitute the expression we found for C1 earlier, to get:
C3 = 1/2 * (1 + C2/√2)

Finally, we can use the fact that v is a vector in R3, which means it can be written in terms of any orthonormal basis. In particular, we can use the given basis B to express v as a linear combination of its basis vectors, and solve for the coefficients C1, C2, and C3.

We have:
v = -1-1 = (-1/√2)bi - b2

Substituting this into the expression we found for C1 earlier, we get:
1/√2 - C2 = 1

Solving for C2, we get:
C2 = -1/√2

Substituting this into the expression we found for C3, we get:
C3 = 1/2 * (1 - 1/√2) ≈ 0.21

Therefore, C3 is approximately 0.21, to 2 digits after the decimal.

The area of the ellipse, = 54.88 square units. To find the area of an ellipse given by the equation 7x² + 44y² = 308, we can use the formula A = πab, where a and b are the lengths of the semi-major and semi-minor axes of the ellipse.

To find these values, we first need to put the equation in standard form, which is:

(x²/a²) + (y²/b²) = 1

To do this, we can divide both sides of the equation by 308 to get:

(x²/44) + (y²/7) = 1

Comparing this with the standard form, we can see that a² = 44 and b² = 7.

Therefore, the area of the ellipse is:

A = πab = π(√44)(√7) = π(2√11)(√7) = 2π√77 ≈ 39.4 square units.

So the area of the ellipse 7x² + 44y² = 308 is approximately 39.4 square units.
To find the area of the ellipse given by the equation 7x^2 + 44y^2 = 308, you need to identify the lengths of the semi-major axis (a) and semi-minor axis (b). The general equation of an ellipse is (x^2 / a^2) + (y^2 / b^2) = 1.

First, divide the entire equation by 308:
(7x^2 / 308) + (44y^2 / 308) = 1

Simplify the equation to match the general form:
(x^2 / (308/7)) + (y^2 / (308/44)) = 1

Now you can see that a^2 = 308/7 and b^2 = 308/44. To find a and b, take the square root of each:
a = sqrt(308/7) ≈ 6.58
b = sqrt(308/44) ≈ 2.66

To find the area of the ellipse, use the formula: Area = πab
Area ≈ 3.14 × 6.58 × 2.66 ≈ 54.88 square units.

This is the equation of the line tangent to the curve x⁶ + 2xy + y³ = 4 at the point (1, 1).

To find the equation of the tangent line to the curve defined by x⁶ + 2xy + y³ = 4 at the point (1, 1), we first need to find the derivative dy/dx using implicit differentiation.

Differentiate both sides of the equation with respect to x:
6x⁵ + 2y(dx/dy) + 2x(dy/dx) + 3y²(dy/dx) = 0

Now, solve for dy/dx:
dy/dx × (2x + 3y²) = -6x⁵ - 2y(dx/dy)
dy/dx = (-6x⁵ - 2y(dx/dy)) / (2x + 3y²)

Since we want to find the tangent line at the point (1, 1), plug in x = 1 and y = 1:
dy/dx = (-6(1)⁵ - 2(1)(dx/dy)) / (2(1) + 3(1)²)
dy/dx = (-6 - 2(dx/dy)) / 5

Now, we can solve for dx/dy and find the slope of the tangent line:
dy/dx = (-6 - 2(dx/dy)) / 5
5(dy/dx) = -6 - 2(dx/dy)
(dy/dx) - 2/5(dx/dy) = -6/5

At the point (1, 1), the tangent line has a slope of dy/dx. Therefore, using the point-slope form of a linear equation, the equation of the tangent line is:
y - 1 = (dy/dx)(x - 1)

Substitute dy/dx with the expression we found earlier:
y - 1 = (-6/5 - 2/5(dx/dy))(x - 1)

A) The length of GR is approximately 21.3 feet.

B) The length of GD is approximately 15.4 feet.

A) To find the length of GR, we can use the formula for the circumference of a circle, which is C = 2πr, where r is the radius of the circle. Since GA is the radius of the circle and GA = 12 feet, the circumference is C = 24π feet. Since the major arc mGR is 200°, it corresponds to 200/360 or 5/9 of the circumference.

Therefore, the length of the major arc GR is (5/9) × 24π = 40π/3 feet. Using the formula for arc length, we have: arc length = (angle/360) × 2πr, where angle is in degrees.

Rearranging this formula, we get: r = arc length / ((angle/360) × 2π). Substituting the values for arc length and angle, we get: r = (40π/3) / ((200/360) × 2π) = 4.5 feet. Finally, using the Pythagorean theorem, we have: GR² = GA² + AR² = (12)² + (4.5)², which gives us GR ≈ 21.3 feet.

B) To find the length of GD, we can use a similar approach as in part A. Since GA is the radius of the circle and GA = 29 feet, the circumference is C = 58π feet. Since the major arc mDG is 185°, it corresponds to 185/360 or 37/72 of the circumference.

Therefore, the length of the major arc DG is (37/72) × 58π = 29.9π/3 feet. Using the formula for arc length, we have: arc length = (angle/360) × 2πr, where angle is in degrees. Rearranging this formula, we get: r = arc length / ((angle/360) × 2π).

Substituting the values for arc length and angle, we get: r = (29.9π/3) / ((185/360) × 2π) = 14.5 feet. Finally, using the Pythagorean theorem, we have: GD² = GA² + AD² = (29)² - (14.5)², which gives us GD ≈ 15.4 feet.

What is exponential?

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

To determine which sample best represents the population, we need to calculate the sample proportions and compare them to the actual proportion of biographies in the population.

Actual proportion of biographies in the population = 570/3000 = 0.19

Sample 1 proportion = 24/50 = 0.48

Sample 2 proportion = 23/25 = 0.92

Sample 3 proportion = 19/100 = 0.19

Sample 2 has a proportion that is significantly different from the actual proportion in the population, so it is unlikely to be a representative sample. Sample 3 has a proportion that is close to the actual proportion, so it is a good candidate for representing the population.

Therefore, the third sample of 19 biographies in 100 books best represents the population.

The remaining balance of the car loan after 28 payments of $487.83 can be calculated to be $20,506.77.

To calculate this, we first need to find the monthly interest rate. We can do this by dividing the annual interest rate (4.2%) by 12 months, giving us a monthly interest rate of 0.35%.

Next, we can use the formula for the present value of an annuity to find the amount of the remaining balance. The present value formula is:

PV = C * ((1 - [tex](1 + r)^{-n[/tex]) / r)

where PV is the present value (or remaining balance), C is the regular payment amount, r is the monthly interest rate, and n is the total number of payments.

To determine the value of the house one year later, we need to multiply the current value of the house by 1.1 (10% increase). So, if the value of the house is currently $223,000, its value one year later would be:

223,000 x 1.1 = $245,300

To determine the percent increase of the house's value from one year to the next during the first five years, we can use the formula:

Percent increase = (New value - Old value) / Old value x 100

For example, to determine the percent increase from year 1 to year 2:

Percent increase = (245,300 - 223,000) / 223,000 x 100 = 10%

To solve this problem, we can use the Pythagorean theorem to relate the distance between the automobile and the farmhouse () to the distance past the intersection of the highway and the road ():

^2 = ^2 + ^2

Taking the derivative of both sides with respect to time, we get:

2()() = 2()()()

Simplifying and solving for (), we get:

() = ()() / ()

Now we just need to plug in the given values:

() = (86 km/h)(3.7 km) / (sqrt((3.7 km)^2 - (1.7 km)^2))

() ≈ 96.308 km/h

Therefore, the distance between the automobile and the farmhouse is increasing at a rate of approximately 96.308 km/h when the automobile is 3.7 km past the intersection of the highway and the road.
To solve this problem, we will use the Pythagorean theorem and differentiate with respect to time.

Let x denote the distance between the automobile and the farmhouse, and y denote the distance past the intersection of the highway and the road. Given that the automobile travels at a speed of 86 km/h, the road to the farmhouse is 1.7 km away, and the automobile is 3.7 km past the intersection, we have:

x^2 = (1.7)^2 + y^2

When the automobile is 3.7 km past the intersection, y = 3.7 km. Differentiating both sides with respect to time (t) gives:

2x(dx/dt) = 2y(dy/dt)

We are given that dy/dt = 86 km/h (the speed of the automobile). Now we need to find x when y = 3.7 km:

x^2 = (1.7)^2 + (3.7)^2
x^2 = 2.89 + 13.69
x^2 = 16.58
x ≈ 4.074 km

Now, substitute the values of x and y into the differentiated equation:

2(4.074)(dx/dt) = 2(3.7)(86)

Solve for dx/dt:

(8.148)(dx/dt) = 635.6
dx/dt ≈ 78.004 km/h

So, the distance between the automobile and the farmhouse is increasing at a rate of approximately 78.004 km/h when the automobile is 3.7 km past the intersection.

What is rectangular-prism?

A cuboid, also known as a rectangular prism, is a three-dimensional solid form or figure with six faces (two top and bottom faces and four lateral faces). The prism's faces are all rectangular and are divided into three pairs by their similarity. Based on its three dimensions, it has a volume and a surface area. The sum of the surfaces of each of its six sides represents the overall surface area.The total area of all of its side faces or four walls makes up the lateral surface area. Its volume can be calculated by multiplying the base area by the height.The volume of cuboid is given by area of base times height or length times width times height.

The given dimensions of the box:

Length=16 feet

To find the dimensions of the bookmark, we need to use the given information about its perimeter and area. The dimensions of the bookmark are 4 centimeters by 8 centimeters.

Let's start by using the formula for the perimeter of a rectangle, which is P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
We know that the perimeter of the bookmark is 24 centimeters, so we can write:
24 = 2(l + w)
Simplifying this equation, we get:
12 = l + w
Now, let's use the formula for the area of a rectangle, which is A = lw, where A is the area, l is the length, and w is the width.
We know that the area of the bookmark is 32 square centimeters, so we can write:
32 = lw
Next, we can use the fact that l + w = 12 to solve for one of the variables in terms of the other. For example, we can solve for l:
l = 12 - w
Substituting this into the equation for the area, we get:
32 = (12 - w)w
Expanding this equation, we get:
32 = 12w - w^2
Rearranging and simplifying, we get a quadratic equation:
w^2 - 12w + 32 = 0
We can solve this equation using the quadratic formula:
w = (12 ± √(12^2 - 4(1)(32))) / (2(1))
Simplifying, we get:
w = 4 or w = 8
If w = 4, then l = 8 (since l + w = 12). If w = 8, then l = 4.
Therefore, the dimensions of the bookmark are either 8 centimeters by 4 centimeters, or 4 centimeters by 8 centimeters.

To find the dimensions of the bookmark with a perimeter of 24 centimeters and an area of 32 square centimeters, follow these steps:
1. Let the length be "L" centimeters and the width be "W" centimeters.
2. The formula for perimeter is P = 2L + 2W. Since the perimeter is 24 centimeters, we have the equation: 24 = 2L + 2W.
3. The formula for area is A = LW. Since the area is 32 square centimeters, we have the equation: 32 = LW.
4. To solve for one of the variables, we can simplify the perimeter equation: 12 = L + W.
5. Next, we can solve for one of the variables in terms of the other. Let's solve for W: W = 12 - L.
6. Now, substitute W in the area equation: 32 = L(12 - L).
7. Expand the equation: 32 = 12L - L^2.
8. Rearrange to form a quadratic equation: L^2 - 12L + 32 = 0.
9. Factor the equation: (L - 4)(L - 8) = 0.
10. Solve for L: L = 4 or L = 8.
11. Use the value of L to find W: If L = 4, W = 12 - 4 = 8; If L = 8, W = 12 - 8 = 4.
The dimensions of the bookmark are 4 centimeters by 8 centimeters.

(a) To find the maximum likelihood estimate of 2, we need to use the Poisson distribution formula:

P(x;λ) = e^(-λ) * (λ^x) / x!

where λ is the mean number of dropped connections per call and x is the observed number of dropped connections.

We want to find the value of λ that maximizes the likelihood of observing 2, 0, 3, and 1 dropped connections in four calls. The likelihood function L(λ) is the product of the individual probabilities:

L(λ) = P(2;λ) * P(0;λ) * P(3;λ) * P(1;λ)
     = e^(-λ) * (λ^2) / 2! * e^(-λ) * (λ^0) / 0! * e^(-λ) * (λ^3) / 3! * e^(-λ) * (λ^1) / 1!
     = e^(-4λ) * λ^6 / 6

To find the maximum likelihood estimate of λ, we take the derivative of the likelihood function with respect to λ and set it equal to zero:

dL(λ)/dλ = (-4e^(-4λ) * λ^6 / 6) + (e^(-4λ) * λ^5) = 0

Simplifying, we get:

-4λ + 6 = 0

λ = 1.5

Therefore, the maximum likelihood estimate of λ is 1.5, which means that we expect 1.5 dropped connections per call on average.

(b) To obtain the maximum likelihood estimate that the next two calls will be completed without any accidental drops, we use the Poisson distribution formula again with λ = 0:

P(x;0) = e^(-0) * (0^x) / x! = 1 / x!

The probability of having no dropped connections in one call is P(0;0) = 1, so the probability of having no dropped connections in two calls is:

P(0,0;0) = P(0;0) * P(0;0) = 1 * 1 = 1

Therefore, the maximum likelihood estimate that the next two calls will be completed without any accidental drops is 1.
Hi! I'm happy to help you with your question.

(a) To find the maximum likelihood estimate of λ (the average number of dropped connections per call), you can use the following formula:

λ = (ΣX) / n

Where ΣX is the sum of the observed dropped connections and n is the total number of calls. In this case, the number of dropped connections is 2 + 0 + 3 + 1 = 6, and there are 4 calls (n = 4). So,

λ = 6 / 4 = 1.5

The maximum likelihood estimate of λ is 1.5.

(b) To obtain the maximum likelihood estimate that the next two calls will be completed without any accidental drops, you need to use the Poisson probability formula:

P(X = k) = (e^(-λ) * (λ^k)) / k!

For k = 0 (no dropped connections in the next two calls), the formula becomes:

P(X = 0) = (e^(-λ * n) * (λ * n)^0) / 0!

Using the previously calculated λ = 1.5 and considering two calls (n = 2), the formula becomes:

P(X = 0) = (e^(-1.5 * 2) * (1.5 * 2)^0) / 0!

P(X = 0) = (e^(-3) * 1) / 1

P(X = 0) ≈ 0.0498

The maximum likelihood estimate that the next two calls will be completed without any accidental drops is approximately 0.0498, or 4.98%.

Based on the given information, we can estimate the probability of receiving the death penalty for the group most likely to receive it by substituting the values of the coefficients into the logistic prediction equation:

P(Y = 1) = exp(a + B1R + B2Y + B3 + B4h + B5i + B6j + B7h*i)

where:

a = -5.26

B1 = 0.00

B2 = 0.17

B3 = 0.00

B4 = 0.91

B5 = 0.00

B6 = 2.02

B7 = 3.98

Assuming that the group most likely to receive the death penalty is a black defendant (h = 1), with a white victim (i = 2), and no additional factors (j = 0), we can plug in these values into the equation:

P(Y = 1) = exp(-5.26 + 0.00R + 0.17Y + 0.00 + 0.911 + 0.002 + 2.020 + 3.981)

P(Y = 1) = exp(-5.26 + 0.91 + 3.98)

P(Y = 1) = exp(-0.37)

Using the exponential function, we can calculate the estimated probability:

P(Y = 1) = 0.691

So, the estimated probability of receiving the death penalty for the group most likely to receive it (a black defendant with a white victim and no additional factors) is approximately 0.691 or 69.1%.

If the constraints B1 = By = B = 0 are used instead, the estimates for the coefficients would be different and would need to be calculated accordingly.
