The correct answer is 2 (C) - 2 days is the total slack for activity F. To determine the total slack for activity F, we need to calculate the slack for each activity in the network. Slack refers to the amount of time an activity can be delayed without affecting the project completion time.

1. First, let's draw the network using the information provided:
  - A is the start node and G is the stop node.
  - Activity A has a duration of 5 days and has no predecessor.
  - Activities B, C, and D have durations of 8, 7, and 6 days respectively, and their predecessors are A.
  - Activity E has a duration of 9 days and its predecessors are B, C, and D.
  - Activity F has a duration of 10 days and its predecessors are B, C, and D.
  - Activity G has a duration of 5 days and its predecessors are E and F.

                 E
                 |
                 F
                 |
                 G

2. Now, let's calculate the slack for each activity:
  - Slack is calculated by subtracting the earliest start time of an activity from the latest start time without delaying the project completion time.
  - The earliest start time for activity F is 17 days.
  - The latest start time for activity F is 19 days (project completion time is 22 days).
  - Total slack for activity F = latest start time - earliest start time = 19 - 17 = 2 days.

Answer:

AB = 24

Step-by-step explanation:

BD = 5x – 26

BC = 2x + 1

AC = 43

Using the segment addition postulate, AC = AB + BC.

We know that BD = BC, BD = 5x-26 and BC = 2x+1.  We can set up an equation to find the value of x:

5x - 26 = 2x + 1   Subtract 2x from each side

5x - 26 - 2x = 2x + 1 - 2x

3x-26 = 1  Add 26 to each side

3x-26+26 = 1+26

3x=27  Divide both sides by 3

3x/3 = 27/3

x = 9

This means that BC = 2x + 1 = 2(9) + 1 = 18 + 1 = 19.

We know that AC = AB + BC; using our given information as well as the value of BC we just found, we have

43 = AB + 19  Subtract 19 from each side

43 - 19 = AB + 19 - 19

24 = AB

The product that is the factored form of the polynomial 3x⁴ - 2x² + 15x² - 10 is (x² + 5)(3x² - 2).

In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

The polynomial is first correctly stated as follows

This is rearranged, grouped and solved as follows:

\(\sf 3x^4+15x^2-2x^2-10\)

\(\sf (3x^4+15x^2)-(2x^2+10)\)

\(\sf 3x^2(x^2+5)-2(x^2+5)\)

Factorizing the common factors, we have the product of the factored form of the polynomial as follows:

\(\boxed{\rightarrow\bold{(x^2 + 5)(3x^2 - 2)}}\)

The Z-test statistic is 2.61 and the P-value is 0.0046. Based on the results, it can be inferred that older students exhibit more positive attitudes towards school compared to the average U.S. college student. To conduct the test, certain assumptions are necessary in addition to assuming the known value of σ: the sample is randomly selected from the population, and the population follows a normal distribution.

(a) The null hypothesis is H0: µ = 117 and the alternative hypothesis is Ha: µ > 117, and we will test the null hypothesis using the Z test statistic.

The test statistic Z is calculated as:

Z = (x¯ - µ) / (σ / sqrt(n))

where x¯ is the sample mean, µ is the population mean, σ is the population standard deviation, and n is the sample size.

Substituting the values we get, Z = (133.8 - 117) / (23 / sqrt(40))Z = 2.61The P-value corresponding to Z = 2.61 is 0.0046 using a Z table.

(b) The P-value of the test is 0.0046, which is less than the significance level of 0.05. Therefore, we can reject the null hypothesis and conclude that older students have better attitudes toward school than the average U.S. college student.

(c) The assumptions required for the test in addition to the assumption that the value of σ is known are:

The sample is a random sample from the population.

The population is normally distributed, or the sample size is large enough (n > 30) for the Central Limit Theorem to apply.

By the triangle midsegment theorem, 2(SP)=RQ.

Answer:

x < 5

Step-by-step explanation:

The alternative that proportionates the greatest quality of the product R is alternative 3. This can be justified mathematically.

In order to determine the greatest quality of the product R, we need to consider the stoichiometry of the reaction and the conditions of the reactors. The fact that the reaction is elemental in the liquid state means that the reaction is highly dependent on the reactant concentrations and the residence time of the reactants in the reactors.

By using plug flow reactors, we ensure that the reactants flow through the reactors without any mixing or backflow. This allows for better control over the reaction conditions and minimizes side reactions.

Alternative 3, which consists of two reactors, will provide a larger total volume for the reaction compared to the other alternatives. This means that the reactants will have a longer residence time in the reactors, allowing for a higher conversion of reactants to product R.

Additionally, the larger volume in alternative 3 will allow for better temperature and concentration control, leading to a higher quality product R.

Therefore, alternative 3 proportionates the greatest quality of the product R based on the stoichiometry of the reaction and the use of plug flow reactors.

Answer: A 90° rotation around the origin maps point (x, y) to (-y, x). So, the image of point J after a 90° rotation is J' = (-2, 2) -> (-2, -2).

A reflection across the line x = 3 maps point (x, y) to (2x - 3, y). So, the image of point J' after a reflection across x = 3 is J'' = (-2, -2) -> (4, -2).

Similarly, we can find the images of K and L:

K' = (-2, 6) -> (-6, -2)

K'' = (-6, -2) -> (-2, -2)

L' = (-8, 2) -> (2, -8)

L'' = (2, -8) -> (8, -2)

Therefore, the image of triangle JKL after the 90° rotation and reflection is triangle PQR, with vertices P = J'', Q = K'', and R = L''.

The area of triangle PQR can be found using the Shoelace Formula:

P = [(4 -2) + (-2 -2) + (8 -2) * (-2 - (-8))]/2 = [6 + 4 * 6]/2 = 30/2 = 15 square units.

So, the area of triangle PQR is 15 square units.

The statement "In the study of logic, p q is to be understood in the exclusive sense, whereby if 'p' and 'q' are both true, the compound claim pvq is, as a whole claim, true" is true.

This principle is known as the exclusive disjunction, which means that the truth value of p v q is only true if either p or q is true, but not both.

In other words, if both p and q are true, then the statement p v q is still considered true because only one of them needs to be true for the whole statement to be true. This concept is essential in the study of logic as it helps to clarify the relationship between different statements and propositions.

Furthermore, this principle is often used in mathematics, computer science, and other fields that rely heavily on logical reasoning. It enables us to make accurate predictions and draw valid conclusions from a set of given premises or statements.

In conclusion, the exclusive disjunction is a crucial concept in the study of logic that helps us understand the truth value of compound claims. Therefore, the statement "In the study of logic, p q is to be understood in the exclusive sense, whereby if 'p' and 'q' are both true, the compound claim pvq is, as a whole claim, true" is true.

In the study of logic, the statement "p ∨ q is to be understood in the exclusive sense, whereby if 'p' and 'q' are both true, the compound claim p ∨ q is, as a whole claim, true" is actually false. This is because the given description refers to the "inclusive" sense of the disjunction (OR) operator, rather than the exclusive sense.

In logic, there are two types of disjunctions: inclusive and exclusive. The inclusive disjunction, represented by p ∨ q, is true when at least one of p or q is true. This means that if both p and q are true, the compound claim p ∨ q is also true, which matches the given description in the question.

On the other hand, the exclusive disjunction, represented by p ⊕ q or p XOR q, is true only when either p or q is true, but not when both are true. If p and q are both true, then the compound claim p ⊕ q is false.

So, the statement in the question actually describes the inclusive disjunction, not the exclusive disjunction, and is therefore false.

The tensions in each side of the rope will be the same when Nellie Newton hangs at rest in the middle of a clothesline and the lengths of each rope are the same.

When Nellie Newton is in equilibrium, meaning she is at rest and not experiencing any acceleration or movement, the forces acting on her must be balanced. In the case of a clothesline, the tension in each side of the rope contributes to the balancing of forces.

For the tensions to be the same in each side of the rope, the lengths of the ropes must also be the same. This ensures that the forces applied to each side are equal and balanced, resulting in Nellie Newton remaining in a stable position without any net force acting on her.

86 liters of 35% salt solution should be added to 20 liters of an 70% salt solution so that the resulting solution contains 45% salt solution .

For given question,

Let x be the quantity ( in liters ) of 35 percent salt solution added to 20 liters of an 70 percent salt solution so that the resulting solution contains 45 percent salt,

Thus,

Quantity of salt solution in 20 liters + Quantity of salt solution in x

= Quantity of salt solution in resultant mixture.

⇒ 70% of 20 + 35% of x = 45% of (20 + x )

⇒ 14 + (0.35x) = 0.45 × ( 12 + x )

⇒ 14 + 0.35x = 5.4 + 0.45x

⇒ 14 - 5.4 = 0.45x - 0.35x

⇒ 8.6 = 0.10x
