The probability that the mean of the repair bills for 12 microwave ovens will be greater than $60 is 0.015 or about 1.5%.

The distribution of the sample means for repair costs of 12 microwave ovens can be approximated to a normal distribution, with a mean of the population repair cost, μ = $55 and a standard deviation of the sample mean, σ/√n = $8/√12 ≈ $2.31.

We need to find the probability that the sample mean is greater than $60. Using the formula for z-score:

z = (x - μ) / (σ / √n)

= (60 - 55) / (2.31)

≈ 2.16

We can look up the area under the standard normal distribution curve for z-score 2.16 in a z-table or calculate it using software. The probability is approximately 0.015.

Therefore, the probability that the mean of the repair bills for 12 microwave ovens will be greater than $60 is 0.015 or about 1.5%.

In the example, we have three bulbs with of r: A, B, and C. Let's examine the conditions of the circuit step by step:

1. When bulb C is installed, bulbs B and C are connected in parallel, creating an equivalent resistance of r/2.2. Bulb A is connected in series with the parallel arrangement of bulbs B and C, and the circuit's overall resistance is 3.3. The total resistance changes to 5r when bulb C is removed, putting bulbs A and B in series.4. Removing bulb C reduces the circuit's current flow since it raises the overall resistance.5.

What is economy?

The creation, distribution, and exchange of goods and services, as well as their consumption, constitute the economy. It is broadly defined as a "social realm emphasising actions, discourses, and material expressions associated with the development, use, and management of finite resources." A given economy is a set of activities with primary variables such as culture, values, education, technological evolution, history, social organisation, political structure, legal systems, and natural resources. These factors provide context and content, as well as the conditions and parameters that govern an economy.

boolean expressions C Just when a and b are accurate. If both requirements of a and b are met, the expression evaluates to true.

Only when both of the requirements in (a && (b ||!a)) == a && b are met does the expression (a && (b ||!a)) == a && b evaluate to true. This is as a result of the expression's use of the logical "AND" operator. Only when both of the conditions on which the "AND" operator is executing are true does it evaluate to true. The first condition in this situation is a && (b ||!a) and the second condition is a && b, both of which can only be satisfied when both a and b are true. As a result, only when both of the conditions for a and b are true does the phrase (a && (b ||!a)) == a && b evaluate to true.

Answer:

C = $0.0032 per day

Explanation:

We are given;

Dimension of cell phone; 50 mm × 45 mm × 20 mm

Temperature of charger; T1 = 33°C = 306K

Emissivity; ε = 0.92

convection heat transfer coefficient; h = 4.5 W/m².K

Room air temperature; T∞ = 22°C = 295K

Wall temperature; T2 = 20°C = 293 K

Cost of electricity; C = $0.18/kW.h

Chargers are usually in the form of a cuboid, and thus, surface Area is;

A = (50 × 45) + 2(50 × 20) + 2(45 × 20)

A = 6050 mm²

A = 6.05 × 10^(-3) m²

Formula for total heat transfer rate is;

E_t = hA(T1 - T∞) + εσA((T1)⁴ - (T2)⁴)

Where σ is Stefan Boltzmann constant with a value of; σ = 5.67 × 10^(-8) W/m².K⁴

Thus;

E_t = 4.5 × 6.05 × 10^(-3) (306 - 295) + (0.92 × 6.05 × 10^(-3) × 5.67 × 10^(-8)(306^(4) - 293^(4)))

E_t = 0.7406 W = 0.7406 × 10^(-3) KW

Now, we know C = $0.18/kW.h

Thus daily cost which has 24 hours gives;

C = 0.18 × 0.7406 × 10^(-3) × 24

C = $0.0032 per day

Music Infringement: The well known musicians, Pharrell Williams and Robin Thicke, were involved in an extended copyright dispute with the estate of Marvin Gaye for similarities between the Williams-Thicke hit, “Blurred Lines”, and Gaye’s earlier hit, “Got to Give It Up”. The courts found that the two tunes were similar enough that the more recent piece of music did, in fact, constitute copyright infringement against Gaye's earlier work.

The area of the gutter is therefore equal to the area of the rectangle plus the area of the triangles.

A = rectangle + 2 * triangle

= 10h + 2 * (1/2 hw)

Using trig work out h and w.

h = 10 sin ?

w = 10 cos ?

A = 10h + hw

= 100sin? + 100sin?cos?

Differentiate the expression (either use the product rule for sin? cos?, or write 100sin?cos? as 50sin2? using the double angle formula)

A = 100sin? + 50sin2?

dA/dt = 100cos? + 100cos2?

For A to be a max or min the derivative must equal zero

100cos? + 100cos2? = 0

cos? + cos2? = 0

Use the double angle formula to write cos2? as 2cos^2 ? - 1

cos? + 2cos^2 ? - 1 = 0

2cos^2 ? + cos? - 1 = 0

This quadratic factorizes:

(2cos? - 1)(cos? + 1) = 0

This means that

cos ? = 1/2 or cos ? = 1

giving:

? = pi/3 or ? = pi

Which means that to achieve the maximum area ? should be pi/3 = 60 degrees

You can check that this is the max by substituting in these values of theta and the two end points (theta = 0, theta = pi), and seeing that pi/3 gives the maximum.

The maximum area is therefore

A = 100sin? + 100sin?cos?

= 100sin(pi/3) + 100sin(pi/3)cos(pi/3)

= 100 sqrt(3) / 2 + 100 sqrt(3)/2 * 1/2

= 100 * 3/2 * sqrt(3) / 2

It is a weakly dominant strategy for each agent i to vote for her ideal location Pi.

(a) The strategic form of the game can be represented as follows:

Agent 1's strategy set: S1 = [0,1]

Agent 2's strategy set: S2 = [0,1]

Agent 1's payoff function: U1(11,12) = -P1 - d(x1,0)

Agent 2's payoff function: U2(11,12) = -P2 - d(x2,0)

Here, P1 and P2 represent the ideal locations of Agent 1 and Agent 2, respectively. x1 and x2 are the voted locations by Agent 1 and Agent 2, respectively. The function d(a,b) represents the distance between points a and b.

(b) To show that it is a weakly dominant strategy for each agent i to vote for her ideal location Pi, we need to compare the payoffs for different strategies of each agent.

For Agent 1:

Suppose Agent 1 votes for a location x' != P1. Let's consider two cases:

1. If x' < P1:

  In this case, the utility of Agent 1 would be U1(x',x2) = -P1 - d(x',0).

  Since x' < P1, the distance d(x',0) would be greater than or equal to the distance d(P1,0).

  Therefore, U1(x',x2) <= -P1 - d(P1,0) = U1(P1,x2).

2. If x' > P1:

  In this case, the utility of Agent 1 would be U1(x',x2) = -P1 - d(x',0).

  Since x' > P1, the distance d(x',0) would be greater than or equal to the distance d(P1,0).

  Therefore, U1(x',x2) <= -P1 - d(P1,0) = U1(P1,x2).

From the above two cases, we can conclude that for Agent 1, voting for any location other than P1 would result in a weakly lower or equal utility compared to voting for P1. Hence, voting for P1 is a weakly dominant strategy for Agent 1.

Similarly, we can show that voting for Pi is a weakly dominant strategy for Agent 2.

More cooking is done before the water actually begins to boil thanks to the raised pressure inside the cooker, which raises the boiling point of water above 1000C. In the end, food cooks more quickly.

Slow-cooked meals can be quickly prepared with pressure cookers. They are efficient in terms of electricity consumption and are excellent for tenderizing less expensive portions of meat. They are a healthy cooking method since they effectively retain nutrients and can cut cooking times by up to 50%. Water boils at 121°C (250°F) at that pressure. As a result, food may cook at considerably greater temperatures than it could under atmospheric pressure.

Answer:

A scientific theory is an explanation of an aspect of the natural world and universe that has been repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment. In circumstances not amenable to experimental testing, theories are evaluated through principles of abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific knowledge.

A scientific theory differs from a scientific fact or scientific law in that a theory explains "why" or "how": a fact is a simple, basic observation, whereas a law is a statement (often a mathematical equation) about a relationship between facts. For example, Newton’s Law of Gravity is a mathematical equation that can be used to predict the attraction between bodies, but it is not a theory to explain how gravity works. Stephen Jay Gould wrote that "...facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts.

If you are driving below 40 mph, you should leave at least one second for every 10 feet of vehicle length.

The elevation and stationing of the high point, PVC, and PVT of the given vertical curve are;

High Point Station = 342+60

PVT Station = 340+00

PVC Station = 340+00

Elevation of High Point = 1350.0 ft

Elevation of PVT = 1325.0 ft

Elevation of PVC = 1345.0 ft

A 520-ft-long equal-tangent crest vertical curve connects tangents that intersect at station 340 + 00 and elevation 1325 ft. The initial grade is +4.0% and the final grade is 2.5%.

Determine the elevation and stationing of the high point, PVC, and PVT. A vertical curve is used to connect two tangents that have differing slope grades, and it is the arc of a parabola. The parabolic arc's vertex is referred to as the high point of the curve.

PVC (point of vertical curvature) is the point where the parabolic arc starts and the tangent line ends, and PVT (point of vertical tangency) is the point where the parabolic arc ends and the tangent line begins.

Therefore, by considering the given data, we can calculate the elevation and stationing of the high point, PVC, and PVT of the vertical curve in the following way;

Stationing of the curve = 340+00. High point of the curve = L/2 + 340+00 = 520/2 + 340+00 = 342+60PVC = 340+00. Elevation of PVC = Elevation of point of intersection + (Initial grade / 100) x Length of the curve 1325 + (4/100) x 520 = 1345 ft.

Elevation of PVT = Elevation of point of intersection + (Final grade / 100) x Length of the curve 1325 + (2.5/100) x 520 = 1350 ft.

Therefore, the elevation and stationing of the high point, PVC, and PVT of the given vertical curve are;

High Point Station = 342+60

PVT Station = 340+00

PVC Station = 340+00

Elevation of High Point = 1350.0 ft

Elevation of PVT = 1325.0 ft

Elevation of PVC = 1345.0 ft
