By using slope intercept , These were the two points on the line: (0,-2) and (7,2).

A line is defined by the equation y = mx + b, which is also known as the slope-intercept form. When the line is graphed, m represents the slope and b the point at which the line intersects the y-axis.

We may use the slope-intercept form of a line, which is y=mx+b where m is the slope and b is the y-intercept, to graph the line y=4/7x-2. Therefore, m=4/7 and b=-2.

These variables allow us to plot two spots along the line. Since the line crosses the y-axis at (0,-2) (the y-intercept), that location will be one of the points.

We can utilize the slope of 4/7 to locate a different point along the line. This indicates that we advance up 4 units in the y direction for every 7 units we move to the right (in the x direction). We can therefore move 7 units to the right and then 4 units up, starting at (0,-2), to reach (7,2).

So now we have two points on the line: (0,-2) and (7,2). These points can be plotted on a coordinate plane, and then a straight line can be drawn through them to create the graph.

The solution to the given initial-value problem is x(t) = e^(2t) [3e^(4t) + 2te^(4t) + 3t^2e^(4t)].

The initial-value problem is defined by the first-order linear system of differential equations x' = A*x, where A is the given matrix and x(0) is the initial condition vector.

To solve this initial-value problem, we first find the eigenvalues and eigenvectors of the matrix A. Then we can express the solution as x(t) = e^(At) * x(0), where e^(At) is the matrix exponential.

After finding the eigenvalues of A to be 2, 4, and 4, and corresponding eigenvectors, we can compute the matrix exponential e^(At) using the formula e^(At) = P * diag(e^(λ_1t), e^(λ_2t), e^(λ_3*t)) * P^(-1), where P is the matrix of eigenvectors.

Finally, substituting the values into the matrix exponential and multiplying it with the initial condition vector x(0), we obtain the solution x(t) as mentioned above.

Step-by-step explanation:

I dont understand the question.

For the customer service survey, the percentage of the men gave an excellent rating is 57.5%.

The percentage of the men who gave an excellent rating can be calculated by dividing the number of men who gave an excellent rating by the total number of men who took the survey and multiplying by 100%.

Total number of customers surveyed = 400 (200 men and 200 women)

Number of men who rated customer service as excellent = 115

Number of women who rated customer service as excellent = 165

To find percentage of the men who gave an excellent rating, formula to be used:

Percentage of the men who gave an excellent rating = (Number of men who rated customer service as excellent / Total number of men who took the survey) x 100%

Therefore,

Percentage of the men who gave an excellent rating = (115/200) x 100%

Percentage of the men who gave an excellent rating = 57.5%

Therefore, the answer is 57.5%.

The 95% confidence interval for the difference between the two population proportions is -0.022 < p₁ - p₂ < 0.222.

Given that,

In a survey, it was discovered that 68% of women and 78% of men preferred computer-assisted education to lectures, respectively. Each sample contained 100 people that were chosen at random.

We have to calculate the 95% confidence range for the difference between the two proportions.

We know that,

The 95% confidence interval for difference between two population proportions is given as follows :

\(((\bar p_{1} -\bar p_{2})\)±\(Z_{0.05/2}\sqrt{\frac{PQ}{n_{1} } +\frac{PQ}{n_{2} }} })\)

Here,

p₁ is 0.78

p₂ is 0.68

n₁ is 100

n₂ is 100

Z is 1.96

P is 0.73

Q is 0.27

So,

((0.78-0.68)±\(1.96\sqrt{\frac{(0.73)(0.27)}{100 } +\frac{(0.73)(0.27)}{100 }} })\)

(0.10±0.122)

(0.10-0.122,0.10+0.122)

The area of the actual rectangular room is 54 square feet.

To find the area of the actual rectangular room, we need to convert the measurements from the floor plan to their corresponding measurements in feet.

Given that the scale is 0.25 inches = 1 foot, we can convert the measurements as follows:

Length: 1.5 inches * (1 foot / 0.25 inches) = 6 feet

Width: 2.25 inches * (1 foot / 0.25 inches) = 9 feet

Now we have the actual measurements of the room in feet. To find the area, we multiply the length by the width:

Area = Length * Width = 6 feet * 9 feet = 54 square feet

Therefore, the area of the actual rectangular room is 54 square feet.

If demand or annual usage increases by 10 percent, the Economic Order Quantity (EOQ) will increase. The EOQ model is used in inventory management to determine the optimal order quantity that minimizes total inventory costs.

The Economic Order Quantity (EOQ) is a model used in inventory management to determine the optimal order quantity that minimizes total inventory costs. It takes into account factors such as demand, holding costs, and ordering costs. When demand or annual usage increases by 10 percent, it means that more units are being consumed or sold within a given time period.

With an increase in demand, the EOQ will also increase. This is because the EOQ formula takes into consideration the trade-off between holding costs and ordering costs. Holding costs are the costs associated with holding inventory, such as warehousing and insurance, while ordering costs are the costs incurred when placing an order, such as administrative and transportation costs.

When demand increases, more units need to be ordered to meet the higher demand. This results in an increase in ordering costs, as more frequent orders will need to be placed. Consequently, the EOQ will increase to find the new optimal order quantity that balances the increased ordering costs with the holding costs.

In summary, if demand or annual usage increases by 10 percent, the EOQ will increase due to the need to order more frequently to meet the higher demand, resulting in increased ordering costs. This adjustment ensures that the inventory management system remains efficient and cost-effective.

No, X or y-axis scale does not have to always start at zero. In a line chart, it's OK to start the axis at a number other than zero

A line that is used to take or mark measurements is known as an axis in mathematics. Two crucial axes of the coordinate plane are the x and y axes. A horizontal number line is the x-axis, while a vertical number line is the y-axis. The coordinate plane is created by the perpendicular intersection of these two axes.

Given,

No, X or y-axis scale does not have to always start at zero.

A line chart encodes data using location (x, y coordinates), whereas a bar chart represents data using length. In a line chart, it's OK to start the axis at a number other than zero despite many claims that they are always misleading since this minute difference influences how a reader utilizes the chart.

The approximate probability that out of 1000 poker hands there will be at least 450 with a single pair is 0.035

This is a binomial distribution problem with n = 1000 and p = 0.42. Let X be the number of poker hands with a single pair out of 1000 poker hands.

To find the probability that there are at least 450 poker hands with a single pair, we need to calculate P(X ≥ 450).

Using the normal approximation to the binomial distribution, we have:

μ = np = 1000 × 0.42 = 420

σ = √(np(1-p)) = √(1000 × 0.42 × 0.58) ≈ 16.08

Using the continuity correction, we can approximate P(X ≥ 450) as P(Z ≥ (449.5 - 420)/16.08) where Z is the standard normal distribution.

P(Z ≥ (449.5 - 420)/16.08) = P(Z ≥ 1.814) ≈ 0.035

Therefore, the approximate probability that out of 1000 poker hands there will be at least 450 with a single pair is 0.035.

The product rule is a technique for finding the derivative of a product of two functions.  Therefore, the derivative of the function f(x) = ex cosh(x) is given by f′(x) = ex (cosh(x) + sinh(x)).

To find the derivative of the given function f(x) = excosh(x), we need to apply the product rule of differentiation.

The product rule states that the derivative of the product of two functions u(x) and v(x) is given by: `(u(x)*v(x))' = u'(x)*v(x) + u(x)*v'(x)`Where u'(x) and v'(x) are the derivatives of u(x) and v(x) respectively. So, let's apply the product rule here.

We have: `f(x) = ex cosh(x)` `=> u(x) = ex and v(x) = cosh(x)` `=> u'(x) = ex and v'(x) = sinh(x)`

Now, we can find the derivative of f(x) using the product rule as follows:f′(x) = u′(x)v(x) + u(x)v′(x)`= ex cosh(x) + ex sinh(x)` `= ex (cosh(x) + sinh(x))`Therefore, the derivative of the function f(x) = ex cosh(x) is given by f′(x) = ex (cosh(x) + sinh(x)).

In calculus, the derivative of a function measures the sensitivity to change of the function value with respect to a change in its argument. The derivative of a function is a fundamental concept of calculus, and it plays a central role in mathematical analysis and applications.

The derivative of a function f(x) at a point x = a is defined as the limit of the difference quotient as h approaches zero, provided the limit exists. The difference quotient is given by: `f'(a) = lim(h → 0) [f(a + h) - f(a)] / h`. Geometrically, the derivative of a function at a point is the slope of the tangent line to the graph of the function at that point.

The tangent line approximates the curve near the point, and the derivative gives the best linear approximation to the function near the point.In this case, we have found the derivative of the function f(x) = ex cosh(x) using the product rule of differentiation.

The product rule is a technique for finding the derivative of a product of two functions. The rule states that the derivative of a product of two functions is equal to the sum of the product of the first function and the derivative of the second function, and the product of the second function and the derivative of the first function.
