Answer:

5. 4 hour 17 minutes

Step-by-step explanation:

Lilith can complete work in 6 hours so every hour she will complete 1/6 of the work

Janice can complete work in “x” hours so every hour she will complete 1/x of the work.

so if they both work together in 2.5 hours

Lilith will complete 2.5(1/6) work

Janice will complete 2.5(1/x) work

so 2.5(1/6) + 2.5(1/x) = 1

=> 1/6 + 1/x = 0.4

=> 1/x = 0.4 - 1/6

=> 1/x = 2.4/6 - 1/6

=> 1/x = 1.4/6

=> 1(6) = 1.4(x)

=> x = 6/1.4 = 5.6/1.4 + 0.4/1.4 = 4 + 0.4/1.4 hours

since 0.4/14 hour = (0.4/14)60 = 17.1  or 17 minutes

so x = 4 hour + 17 minutes

we compute the dot product and integrate term by term:

\(\int F . dr2 = \int(0 to 1) [(t^2 / (2t^2), (1 - t)^2) . (dt, -dt)].\)

What do you mean by integrate?

When we integrate a function, we are essentially calculating the area under the curve represented by the function within a specific interval. Integration has various applications, such as determining displacement from velocity, finding the total accumulated value over time, calculating areas and volumes, and solving differential equations.

After calculating the integrals for both parts of the region, add the results to obtain the final value of the integral ∫ F · dr over the given region.

To evaluate the integral ∫ F · dr over the region bounded by the triangle with vertices at (1, 0), (0, 1), and (1, 0), oriented counterclockwise, where F = \((y^2 / (2r^2), y^2)\), we can divide the region into two parts and compute the integrals separately. Let's consider the two parts of the region.

Part 1: The line segment from (1, 0) to (0, 1)

To parameterize this line segment, we can use a parameter t that ranges from 0 to 1. Let's call the parameterized curve r1(t). We have:

r1(t) = (1 - t, t), for 0 ≤ t ≤ 1.

To compute ∫ F · dr over this line segment, we substitute the parameterized curve r1(t) into F and compute the dot product:

\(F(r1(t)) = (t^2 / (2(1 - t)^2), t^2).\)

dr1(t) = (-dt, dt).

Now, we can evaluate the integral:

\(\int F . dr1 = \int(0 to 1) [(t^2 / (2(1 - t)^2), t^2) . (-dt, dt)].\)

Simplifying the dot product and integrating term by term, we get:

\(\int F . dr1 = \int(0 to 1) [-(t^2 / (2(1 - t)^2)) dt + t^2 dt].\)

Evaluate each integral separately:

\(\int(-(t^2 / (2(1 - t)^2)) dt = -\int(0 to 1) (t^2 / (2(1 - t)^2)) dt.\\\\\int(t^2 dt) = \int(0 to 1) t^2 dt.\)

Evaluate these integrals and add the results.

Part 2: The line segment from (0, 1) to (1, 0)

Similarly, we can parameterize this line segment using a parameter t that ranges from 0 to 1. Let's call the parameterized curve r2(t). We have:

r2(t) = (t, 1 - t), for 0 ≤ t ≤ 1.

Following the same process as in Part 1, we compute the dot product and integrate term by term:

\(\int F . dr2 = \int(0 to 1) [(t^2 / (2t^2), (1 - t)^2) . (dt, -dt)]\).

Evaluate each integral separately.

After calculating the integrals for both parts of the region, add the results to obtain the final value of the integral ∫ F · dr over the given region.

Answer:

the 30th term is 239

Step-by-step explanation:

The computation of the 30th term is as follows:

As we know that

a_n = a_1 + (n-1)d

where

a_1 is the first number is the sequence

n = the term

And, d = common difference

Now based on this, the 30th term is

= 152 + (30 - 1) × 3

= 152 + 29 × 3

= 152 + 87

= 239

Hence, the 30th term is 239

The length of the base of the parallelogram is 16 inches.

What is parallelogram?

A parallelogram is a four-sided plane figure with opposite sides parallel and congruent (having the same length). This means that the opposite sides of a parallelogram are parallel to each other and have the same length. Additionally, the opposite angles of a parallelogram are equal in measure, which means they have the same degree of rotation.

Let's use the information given in the problem to set up an equation and solve for the length of the base.

From the problem, we know that the height of the parallelogram is 5 inches.

h = 5

We also know that the base of the parallelogram is six more than twice the height. Let's use b to represent the length of the base:

b = 2h + 6

Now we can substitute the value we know for the height and solve for the base:

b = 2(5) + 6

b = 10 + 6

b = 16

Therefore, the length of the base of the parallelogram is 16 inches.

The rate of change of h(x) with respect to x when x=2 is -3. To find d/dx, we need to take the derivative of the function h(x) and evaluate it at x=2.

h(2) tells us that when x=2, h(x)=4.

h'(2) tells us that the slope of the tangent line to the graph of h(x) at x=2 is -3.

So, we can use this information to find d/dx as follows:

h(x) = y

dy/dx = h'(x)

We know that when x=2, y=h(2)=4.

We also know that the slope of the tangent line to the graph of h(x) at x=2 is h'(2)=-3.

So, we can write the equation of the tangent line at x=2 as:

y - 4 = (-3)(x - 2)

y = -3x + 10

Now we can take the derivative of y with respect to x to find d/dx:

d/dx (y) = d/dx (-3x + 10)

d/dx (y) = -3

Therefore, d/dx = -3.

A Florida citrus grower estimates that if 30 orange trees are planted, each tree will produce 500 oranges. For each additional tree planted on the same acreage, the number of oranges each tree produces will decrease by 10 oranges. Find the maximum number of oranges the citrus grower can produce. How many trees will the citrus grower need to plant?

Solution:

Let x represent the number of orange trees above 30 to be planted on the acreage and let y be the number of oranges. Since for every additional tree there is a decrease of 10 oranges, hence:

y = (30 + x)(500 - 10x)

y = 15000 - 300x + 500x - 10x²

y = 15000 + 200x - 10x²

The number of oranges is maximum at y' = 0. Hence:

y' = 200 - 20x

200 - 20x = 0

20x = 200

x = 10

Second derivative test = y" = -20 (so this is maximal)

Therefore the number of trees needed = 30 + 10 = 40 trees

Maximum number of oranges = (30 + 10)(500 - 10(10)) = 40(400) = 16000 oranges

The grade of a highway up a hill is 26%, therefore the amount of change in horizontal distance if the vertical height of the hill is 600 feet is 2307ft.

This is referred to as the numerical or occasionally qualitative measurement of how far apart objects or points are.

First, express the grade as a decimal.

26% → 0.26

Grade = (change in vertical height) / (change in horizontal distance)

0.26 = (600 ft) / x

x = (600 ft) / 0.26 = 2307 ft

The linear regression y = β1 + β2x + e, assuming that the sum of squared errors (SSE) takes the following form:

SSE = 382 + 681 + 382 + 18β1β2

Derive the partial derivatives of SSE with respect to β1 and β2 and solve the optimal values of these parameters.

Given that SSE = 382 + 681 + 382 + 18β1β2 ∂SSE/∂β1 = 0 ∂SSE/∂β2 = 0

Now, we need to find the partial derivative of SSE with respect to β1.

∂SSE/∂β1 = 0 + 0 + 0 + 18β2 ⇒ 18β2 = 0 ⇒ β2 = 0

Therefore, we obtain the optimal value of β2 as 0.

Now, we need to find the partial derivative of SSE with respect to β2. ∂SSE/∂β2 = 0 + 0 + 0 + 18β1 ⇒ 18β1 = 0 ⇒ β1 = 0

Therefore, we obtain the optimal value of β1 as 0. Hence, the partial derivative of SSE with respect to β1 is 18β2 and the partial derivative of SSE with respect to β2 is 18β1.

Thus, the optimal values of β1 and β2 are 0 and 0, respectively.

The equation ax + by = c has integer solutions if and only if (a,b) | c, as the presence of integer solutions implies the divisibility of the GCD, and the divisibility of the GCD guarantees the existence of integer solutions.

The equation ax + by = c represents a linear Diophantine equation, where a, b, c, x, and y are integers. The statement "(a,b) | c" denotes that the greatest common divisor (GCD) of a and b divides c.

To understand why ax + by = c has integer solutions if and only if (a,b) | c, we need to consider the properties of the GCD.

If (a,b) | c, it means that the GCD of a and b divides c without leaving a remainder. In other words, a and b are both divisible by the GCD, and thus any linear combination of a and b (represented by ax + by) will also be divisible by the GCD. Therefore, if (a,b) | c, it ensures that there exist integer solutions (x, y) that satisfy the equation ax + by = c.

Conversely, if ax + by = c has integer solutions, it implies that there exist integers x and y that satisfy the equation. By examining the coefficients a and b, we can see that any common divisor of a and b will also divide the left-hand side of the equation. Hence, if there are integer solutions to the equation, the GCD of a and b must divide c.

To calculate the standard deviation of the number of people with the disease in samples of size 200, we can use the binomial distribution.

The binomial distribution has a mean (μ) equal to the product of the sample size (n) and the prevalence of the disease (p). In this case, μ = n * p = 200 * 0.102 = 20.4.

The standard deviation (σ) of the binomial distribution is given by the square root of the product of the sample size (n), the prevalence of the disease (p), and the complement of the prevalence (1 - p). Therefore, σ = √(n * p * (1 - p)).

Let's calculate the standard deviation:

σ = √(200 * 0.102 * (1 - 0.102)) ≈ √(20.4 * 0.898) ≈ √18.3504 ≈ 4.28 (rounded to 1 decimal place)
