To determine the number of tons of metal per year needed for Machine A to be favored over Machine B, we compare their costs. Machine A costs $323,000 with an annual operating cost of $2.40/ton, while Machine B costs $178,000 with an annual operating cost of $8.00/ton. The machines have useful lives of 10 years and 6 years, respectively, and the minimum attractive rate of return (MARR) is 18% per year.

By calculating the equivalent annual costs (EAC) for each machine using the given formula and comparing them, we can determine the point at which Machine A becomes more favorable. However, specific values for the discounting factors and the tons per year needed are missing, making it impossible to provide an exact answer.

The square root of 9 is 3.

In quadrilateral EFGH, sides FG and EH are congruent because they each have a length of 7.07

The area of quadrilateral EFGH is closest to 30 square units.

From the question, we have the following parameters that can be used in our computation:

Answer: The prime factorization is 3*11*11.

In terms of convergence and stability, some policies fairness in congestion control, such as: Additive Increase Additive Decrease (AIAD), Multiplicative Increase Additive Decrease (MIAD), and Multiplicative Increase Multiplicative Decrease (MIMD); are best known for their use in TCP congestion control. By controlling the data packets’ flow into the network, congestion management allows more effective usage of a shared network infrastructure.

Additive Increase Additive Decrease (AIAD) is a feedback control algorithm which combines linear growth of the congestion window when there is no congestion with an exponential reduction when congestion is detected. This is the policy that follows the rule:

a (i) > 0, b (i) = 1, a (d) < 0 b (d) = 1

This policy does not converge to fairness that means it is not stable. This does not converge to efficiency and if it is need to be stable then it must satisfy the condition a (d) = a (i).

Multiplicative Increase Additive Decrease (MIAD) is a feedback control algorithm which adapt the number of neighbors to which a packet is forwarded. This current number of neighbors is maintained at each node in a control variable based on locally observed error (packet loss) conditions. This is the policy which follows the rule:

a (i) = 0, b (i) > 1, a (d) < 0, b (d) = 1

This policy does not converge to fairness that means it is not stable. This does not converge to efficiency and if it is need to be stable then it must satisfy the condition b (i) a (d) / 1 – b (i).

Multiplicative Increase Multiplicative Decrease (MIMD) is a feedback control algorithm which defined as very aggressive and non-altruistic. This is the policy which follows the rule:

a (i) = 0, b (i) > 1, a (d) = 0, 0 < b (d) < 1

This policy does not converge to fairness that means it is not stable. This does not converge to efficiency and if it is need to be stable then it must satisfy the condition b (i) ≥ 1 and 0 ≤ b (d) < 1.

there are 32 fluid ounces. (8 fluid ounces per cup.)

The fluid ounce was originally the volume that one ounce of a material occupied, such as water or wine (in England) (in Scotland). The ounce in question also differed according on the fluid measurement method being employed, such as wine vs ale. Although it is occasionally referred to as simply "one ounce" when the context makes the meaning apparent, the fluid ounce differs from the (international avoirdupois) ounce as a measure of weight or mass (e.g., "ounces in a bottle"). One imperial fluid ounce of pure water has a mass of approximately precisely one ounce.

The 90% confidence interval for the population proportion of tenth graders reading at or below the eighth-grade level is (0.179, 0.220).

Firstly, determine the sample proportion:
The number of students reading at or below the eighth-grade level = Total students sampled - Students reading above the eighth-grade level

The number of students reading at or below the eighth-grade level = 1042 - 834

The number of students reading at or below the eighth-grade level= 208 students.
Sample proportion (p) = 208/1042

p = 0.1996 (rounded to four decimal places).

Now, we will determine the standard error (SE) for the sample proportion:
SE = √(p * (1 - p) / n)

= √(0.1996 * (1 - 0.1996) / 1042)

≈ 0.0124 (rounded to four decimal places)

Now, determine the z-score corresponding to the 90% confidence interval:
Since it is a 90% confidence interval, we will look for the z-score that has 0.05 in each tail (1 - 0.90 = 0.10, and 0.10 / 2 = 0.05). The z-score for a 90% confidence interval is 1.645.

Now, calculating the margin of error (ME):
ME = z-score * SE

= 1.645 * 0.0124 ≈ 0.0204 (rounded to four decimal places)

Lastly, constructing the 90% confidence interval:
Lower limit = p - ME

= 0.1996 - 0.0204

= 0.179 (rounded to three decimal places)
Upper limit = p + ME

= 0.1996 + 0.0204

= 0.220 (rounded to three decimal places)

So, the 90% confidence interval for the population proportion of tenth graders reading at or below the eighth-grade level is (0.179, 0.220).

the range in this set of data is 25 inches. To find the range of snowfall amounts, we need to look at the line plot and identify the highest and lowest amounts of snowfall that were recorded.

The range in a set of data is the difference between the maximum and minimum values in the set.

To find the range of snowfall amounts, we need to look at the line plot and identify the highest and lowest amounts of snowfall that were recorded.

Let's say that the highest amount recorded was 30 inches and the lowest amount recorded was 5 inches. Then the range would be:

range = highest amount - lowest amount

range = 30 - 5

range = 25

Answer:

1. (a+b)²/a.b/(a+b)(a-b)

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

\(\frac{x}{2}\) + \(\frac{y}{2}\) = 1 ( multiply through by 2 to clear the fractions )

x + y = 2 ( subtract x from both sides )

y = - x + 2 ← in slope- intercept form

(a) with slope m = - 1

(b) with y- intercept c = 2

(c)

Parallel lines have equal slopes, thus

y = - x + c ← is the partial equation of PQ

To find c substitute (2, - 8) into the partial equation

- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6

y = - x - 6 ← equation of PQ

To show (- 1, - 5) lies on PQ, substitute x = - 1 into the equation and evaluate for y.

y = - (- 1) - 6 = 1 - 6 = - 5 ← the given y- coordinate

Thus PQ passes through (- 1, - 5 )

the equation of the ellipse with the given conditions is:

\(x^2/6.25 + y^2/4 = 1\).

To find the equation of the ellipse with center at the origin, major axis on the x-axis, and passing through the points (4,3) and (-1,4), we need to determine the coordinates of the foci and the lengths of the major and minor axes.

1. Center: The center of the ellipse is at the origin (0,0) since it has a center at the origin.

2. Major Axis: The major axis is on the x-axis. Since the major axis passes through the points (4,3) and (-1,4), the length of the major axis is the distance between these two points: 4 - (-1) = 5.

3. Minor Axis: The minor axis is perpendicular to the major axis and passes through the center of the ellipse (0,0). Since the major axis is on the x-axis, the minor axis is on the y-axis. The length of the minor axis can be determined by finding the distance between the y-coordinate of one of the given points and the center (0,0): 4 - 0 = 4.

4. Foci: To find the foci of the ellipse, we need to use the equation c^2 = a^2 - b^2, where a is the length of the semi-major axis and b is the length of the semi-minor axis. Since the center is at the origin, the coordinates of the foci are (±c, 0).

The semi-major axis, a, is half the length of the major axis, so a = 5/2 = 2.5.

The semi-minor axis, b, is half the length of the minor axis, so b = 4/2 = 2.

Using the equation c^2 = a^2 - b^2, we can solve for c:

c^2 = 2.5^2 - 2^2

c^2 = 6.25 - 4

c^2 = 2.25

c = ±√2.25 = ±1.5

Therefore, the foci are located at (±1.5, 0).

Finally, we can write the equation of the ellipse in standard form:

\(x^2/a^2 + y^2/b^2 = 1\)

Substituting the values of a and b, we have:

\(x^2/(2.5^2) + y^2/(2^2) = 1\)

\(x^2/6.25 + y^2/4 = 1\)

Answer :

13%

Step-by-step explanation:

Compound interest which is compounded annually calculated using the formula :

A = I( 1 + r/100)^t

Where I = invested amount

r = interest rate ; t = period ; A = final amount

If period = 9years, the rate required to triple the investment equals;

The final amount = 3 * invested amount = 3I

We now have ;

3I = I( 1 + r/100)^9

Divide both sides by I

3 = (1 + r/100)^9

Take the 9th root of both sides

3^(1/9) = (1 + r/100)^(9*1/9)

3^(1/9) = 1 + r/100

r/100 = 3^(1/9) - 1

r/100 = 1.1298309 - 1

r / 100 = 0.1298309

Multiply both sides by 100

r = 12.98309

r = 12.98 = 13%
