Please help me with 7, 8 and 9 I dont know how to distribute property

39 subjects were tested in this simple one-way ANOVA.

The df for F distribution is (treatment df, error df)

Using given information

Treatment df = 7

Error df = 31

Total df= 7+31 = 38

Again, total df = N-1, N= number of subjects tested

Then, N-1 = 38

=> N= 39

One-way ANOVA is typically used when there is a single independent variable or factor and the goal is to see whether variation or different levels of that factor have a measurable effect on the dependent variable.

The t-test is a method of determining whether two populations are statistically different from each other, and ANOVA determines whether three or more populations are statistically different from each other.

= 5 (the answer is 5)

In other words, based on the given sample, we can say with 90% confidence that between 13.5% and 16.5% of adult Americans have used their smartphone to make a purchase.

To find the 90% confidence interval for the population proportion of adult Americans who have used their smartphone to make a purchase, we can use the following formula:

CI = p ± z*√((p(1-p))/n)

where:

p = sample proportion

= 542/3611

= 0.15 (rounded to two decimal places)

n = sample size

= 3611

z = z-score for 90% confidence level

= 1.645 (from standard normal distribution table)

Plugging in the values, we get:

CI = 0.15 ± 1.645*√((0.15(1-0.15))/3611)

= 0.15 ± 0.015

This means that we are 90% confident that the true proportion of adult Americans who have used their smartphone to make a purchase is somewhere between 0.135 and 0.165.

Correct option is: yes, the lines are intersect at right angle.

Two lines are perpendicular if they cross at a point where they provide a pair of linear angles that are congruent. If a transversal in a plane is parallel to one of two parallel lines, it is also parallel to the other line. Lines that cross at a straight angle (90°) are said to be perpendicular. Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane. Vertical and horizontal lines, or the axes of the coordinate plane, are perpendicular to one another. Two parallel lines' slopes have negative reciprocal slopes.

on using  disjunctive syllogism to derive Q from the second premise and the derived value of A. if P is true, then Q must also be true..

In logic, a compound statement is made up of two or more simple statements, known as premises or assumptions, that are combined using logical operators such as "and," "or," and "not." To prove a compound statement, we use rules of inference to derive a conclusion based on the given premises.

In the first proof question, we are given three premises: P, P or R, and not S or A. We need to prove the statement Q using these premises. To do so, we use the disjunctive syllogism rule, which states that if one of two disjunctive statements is false, then the other must be true. By assuming ~P, we derive ~S from the third premise using the rule of disjunction. Then, using modus ponens, we derive A from the assumption of ~P and the third premise. Finally, we use disjunctive syllogism to derive Q from the second premise and the derived value of A.

In the second proof question, we are given three premises: not P or S, not S, and R or Q. We need to prove the statement P implies Q using a conditional world proof. We assume P is true and derive S using the first premise. Using the second premise and modus tollens, we derive not R. Finally, using disjunctive syllogism, we derive Q from the third premise and the derived value of not R. Therefore, we show that if P is true, then Q must also be true..

Option a. Linear graph; solution set is a line segment.

Step-by-step explanation: The given system of inequalities is:y < -3x - 2 ……….. (1)

y > -3x + 8 ……….. (2)

Let's draw the graphs of the given inequalities: Graph of y < -3x - 2:First, draw the line y = -3x - 2:Mark a point at (0, -2).

Slope of the line is -3, i.e. it falls 3 units for each 1 unit it runs. Move 1 unit to the right and 3 units down from (0, -2) and mark another point. Connect both points to draw a straight line. Since y is less than -3x - 2, the solution set will lie below the line and will not include the line itself. Graph of y > -3x + 8:First, draw the line y = -3x + 8:Mark a point at (0, 8).Slope of the line is -3, i.e. it falls 3 units for each 1 unit it runs. Move 1 unit to the right and 3 units down from (0, 8) and mark another point. Connect both points to draw a straight line.

The average number of repairmen present at any given time in the auto shop can be calculated using Little's Law, which states that the average number of entities in a system is equal to the average arrival rate multiplied by the average time spent in the system. In this case, the average arrival rate is 10 cars per day, and the average time spent in the system (technician working on a car) is 7 days. Therefore, the average number of repairmen present at any given time is:

Average number of repairmen = Average arrival rate * Average time spent = 10 cars/day * 7 days = 70 repairmen

The state space diagram of the Continuous-Time Markov Chain (CTMC) for this scenario can be represented as follows:

State 0: No cars in the system

State 1: 1 car being repaired

State 2: 2 cars being repaired

...

State 80: 80 cars being repaired (maximum capacity)

The transitions between states are determined by the arrivals and departures of cars. Each arrival increases the state by 1, and each departure decreases the state by 1.

The probability that the car shop has to turn away customers due to the lack of repairmen available can be determined by calculating the probability of the system being at the maximum capacity (80 cars being repaired). This can be calculated using the formula for the steady-state probability distribution of a CTMC. Without further information about the arrival and departure rates, it is not possible to provide an exact probability.

To ensure that the probability of turning away customers is less than 1%, the auto shop would need to recruit enough repairmen to increase the maximum capacity of the system. This would depend on the arrival and departure rates, and a detailed analysis would be required to determine the exact number of repairmen needed.

If the turned away cars are kept on a waiting list instead of being rejected, the waiting time for a car to be repaired would depend on the number of cars in the system and the rate at which repairs are completed. To ensure that the waiting time for a car is less than 2 days, the auto shop would need to recruit enough repairmen to reduce the average time spent in the system to less than 2 days. The exact number of repairmen required would depend on the arrival rate of cars and the rate at which repairs are completed, and a detailed analysis would be necessary to determine the specific number.

In this problem, we are given the percentage of bags that are underweight, satisfactory, and overweight. We are asked to find the probability of selecting three bags that are either underweight, satisfactory, or overweight.

To find the probability of selecting three bags that are overweight, we need to multiply the probability of selecting one overweight bag by itself three times, since we are selecting three bags. The probability of selecting one overweight bag is 7.5%, or 0.075. Therefore, the probability of selecting three overweight bags is (0.075)^3 = 0.000421875, or approximately 0.042%.

To find the probability of selecting three bags that are satisfactory, we also need to multiply the probability of selecting one satisfactory bag by itself three times. The probability of selecting one satisfactory bag is 90%, or 0.9. Therefore, the probability of selecting three satisfactory bags is (0.9)^3 = 0.729, or approximately 72.9%.

Multiply, and we get

\(n(n + 1)(n + 2)\)

(a) -2.5A has an x-component of 13.225 m and a y-component of -10.857 m. (b) For A + B, the magnitude is approximately 18.098 m, and the direction is approximately 14.198° counterclockwise from the +x-axis. (c) For A - B and B - A, both have a magnitude of approximately 28.506 m, and the direction is approximately -8.080° counterclockwise from the +x-axis.

Given Magnitude of vector A: |A| = 7.5 m

Angle from the positive x-axis: θ = 145° (counterclockwise)

(a) X-component of vector A:

Ax = |A| * cos(θ)

  = 7.5 * cos(145°)

  ≈ -5.290 m

(b) Y-component of vector A:

Ay = |A| * sin(θ)

  = 7.5 * sin(145°)

  ≈ 4.343 m

Now, let's calculate the components of vector -2.5A.

(a) X-component of -2.5A:

(-2.5A)x = -2.5 * Ax

        = -2.5 * (-5.290 m)

        ≈ 13.225 m

(b) Y-component of -2.5A:

(-2.5A)y = -2.5 * Ay

        = -2.5 * (4.343 m)

        ≈ -10.857 m

Next, let's consider vector B, which has triple the magnitude of vector A and points in the +x direction.

Given:

Magnitude of vector B: |B| = 3 * |A| = 3 * 7.5 m = 22.5 m

Direction: Since vector B points in the +x direction, the angle from the positive x-axis is 0°.

Now, we can calculate the desired quantities using vector addition and subtraction.

(a) A + B: Magnitude: |A + B| = :\(\sqrt{((Ax + Bx)^2 + (Ay + By)^2)}\)

                  = \(\sqrt{((-5.290 m + 22.5 m)^2 + (4.343 m + 0)^2)}\)

                  = \(\sqrt{((17.21 m)^2 + (4.343 m)^2)\)

                  ≈ 18.098 m

Direction: Angle from the positive x-axis = atan((Ay + By) / (Ax + Bx))

                                        = atan((4.343 m + 0) / (-5.290 m + 22.5 m))

                                        = atan(4.343 m / 17.21 m)

                                        ≈ 14.198° (counterclockwise from the +x-axis)

(b) A - B: Magnitude: |A - B| = \(\sqrt{((Ax - Bx)^2 + (Ay - By)^2)}\)

                  = \(\sqrt{((-5.290 m - 22.5 m)^2 + (4.343 m - 0)^2)}\)

                  = \(\sqrt{((-27.79 m)^2 + (4.343 m)^2)}\)

                  ≈ 28.506 m

Direction: Angle from the positive x-axis = atan((Ay - By) / (Ax - Bx))

                                        = atan((4.343 m - 0) / (-5.290 m - 22.5 m))

                                        = atan(4.343 m / -27.79 m)

                                        ≈ -8.080° (counterclockwise from the +x-axis)

(c) B - A:Magnitude: |B - A| = \(\sqrt{((Bx - Ax)^2 + (By - Ay)^2)}\)

                  = \(\sqrt{((22.5 m - (-5.290 m))^2 + (0 - 4.343 m)^2)}\)

                  = \(\sqrt{((27.79 m)^2 + (-4.343 m)^2)}\)

                  ≈ 28.506 m

Direction: Angle from the positive x-axis = atan((By - Ay) / (Bx - Ax))

                                        = atan((0 - 4.343 m) / (22.5 m - (-5.290 m)))

                                        = atan((-4.343 m) / (27.79 m))

                                        ≈ -8.080° (counterclockwise from the +x-axis)

The vertex of the Quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

The vertex of a quadratic function given the y-intercept and x-intercept, we need to determine the axis of symmetry, which is the line that passes through the vertex. The x-coordinate of the vertex will be the midpoint between the x-intercepts, while the y-coordinate will be the same as the y-intercept.

Given that the y-intercept is (5, 0) and the x-intercept is (0, 80), we can determine the x-coordinate of the vertex by finding the midpoint of the x-intercepts. The x-coordinate of the midpoint is simply the average of the x-values:

x-coordinate of vertex = (0 + 0) / 2 = 0 / 2 = 0

Since the y-coordinate of the vertex is the same as the y-intercept, the vertex will have the coordinates (0, 0).

Therefore, the vertex of the quadratic function is (0, 0).

In conclusion, the vertex of the quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).
