For most uses you'll want your water heated to 120 F(49 C) In this example you'd need a demand water heater that produces a temperature rise and it will take about 2 hours

The number of trays that should be prepared if the owner wants a service level of at least 95% is; 7 trays

We are given;

Mean; μ = 15

Standard Deviation; σ = 5

We are told that the distribution of demand score is a bell shaped distribution that is a normal distribution.

Formula for z-score is;

z = (x' - μ)/σ

We want to find the value of x such that the probability is 0.95;

P(X > x) = P(z > (x - 15)/5) = 0.95

⇒ 1 -  P(z ≤ (x - 15)/5) = 0.95

Thus;

P(z ≤ (x - 15)/5) = 1 - 0.95

P(z ≤ (x - 15)/5) = 0.05

The value of z from the z-table of 0.05 is -1.645

Thus;

(x - 15)/5 = -1.645

The match for longitudinal bar diameter with minimum size of fitment is Up to N20 single bar - b) N10, N24 to N36 single bar - c) N12, and Bundle bars - a) N6.

The size and design of the reinforcing bars used in construction influence how closely the longitudinal bar diameter matches the minimal size of fitting.

The minimum size of fitment is normally N10, which refers to a minimum bar diameter of 10mm, for bars up to N20, which refers to smaller diameter bars.

These more compact bars are frequently employed for lighter loads or in locations where less reinforcing is required.

The lowest size of fitment is often N12, which denotes a minimum bar diameter of 12mm, with larger bars ranging from N24 to N36, which are larger diameter bars.

The minimum size of fitment for bundle bars, which are many bars bundled together, is N6, which translates to a minimum bar diameter of 6mm.

There are a few reasons why it might be a better decision to swerve around a stopped car in front of you rather than to brake. Firstly, if you are driving at a high speed, braking suddenly can cause your vehicle to skid or lose control, increasing the risk of a collision.

Secondly, if there are other cars behind you, sudden braking could cause them to collide with you from behind. Additionally, swerving around the stopped car can create more space between you and the obstacle, reducing the likelihood of a collision. However, it is important to note that swerving should only be done if it is safe to do so and if there is enough space to maneuver around the obstacle. It is always important to prioritize safety and avoid making sudden or erratic maneuvers while driving. In some situations, it might be a better decision to swerve around a stopped car in front of you than to brake because swerving can help you avoid a collision more effectively if you don't have sufficient distance or time to stop safely. Braking may not always be the most efficient response, particularly when traveling at high speeds or when road conditions affect your vehicle's stopping distance. However, it's important to evaluate each situation individually and make a decision based on the specific circumstances, ensuring you prioritize the safety of all road users.

Swerving around a stopped car in front of you might be a better decision than braking in certain situations. This is because braking suddenly can cause your car to skid and potentially collide with the stopped car. Additionally, if there are cars following you closely, sudden braking could cause a chain reaction of collisions.

On the other hand, if there is enough space on either side of the stopped car and you are able to swerve around it safely, this could prevent a collision altogether. However, it is important to note that swerving should only be done if it is safe to do so, and if you have enough control over your car to avoid hitting any other objects or pedestrians.

Ultimately, the decision to swerve or brake will depend on the specific situation and the driver's ability to assess the risks and make a quick and safe decision.

The particle acceleration in the x direction at section 2 when t = 1 second is approximately 2.71 U_y m/s², where U_y = 2 m/s.

To find the particle acceleration in the x direction at section 2 when t = 1 second, we need to find the velocity profile at section 2 and then differentiate it with respect to time.

From the continuity equation, we know that the velocity at section 2 is:

V_2 = (A_1/A_2) V_1 = (R_1²/R_2²) U + (R_2²-R_1²)/(R_2²) U_y sin(wt)

Substituting the given values, we get:

V_2 = 320 + 16U_y sin(0.3) m/s

At t = 1 second, we have:

V_2 = 320 + 16U_y sin(0.3) ≈ 329.24 m/s

Now, we can differentiate V2 with respect to time to find the particle acceleration in the x direction:

dV_2/dt = 4.8U_y cos(0.3) ≈ 2.71 U_y m/s²

Therefore, the particle acceleration in the x direction at section 2 when t = 1 second is approximately 2.71 U_y m/s².

It would depend if you're combining channels or not. Assuming your' only using 1 channel per amp then the 120 W amp will be 45 W more powerful. this also assumes that the Ohm rating on the amps is the same. In terms of percentage increase, it would be a 60% increase in power.

Explanation:

Based on the ratings on both channels and the sound they can produce when at maximum, the difference will be 2.04 dB.

Decibel = 10 x Log (Stereo current / Threshold of hearing)

= (10 x Log (120 / Threshold of hearing)) - (10 x Log (75/ Threshold of hearing))

= 10 x Log ( (120/ Threshold) x (Threshold / 75)

The number of possible schedules increases rapidly as the number of processes to be scheduled increases. For example, if we have four processes to be scheduled, there are 4! = 24 possible schedules.

There are several CPU scheduling algorithms available in computer science that determine the order of execution of processes scheduled on a processor. When given n processes to be scheduled on a single processor, the number of different schedules that can be created is calculated using the formula.



To understand this, let's consider a simple example where we have three processes to be scheduled: P1, P2, and P3. To calculate the number of possible schedules, we need to find the factorial of 3, which is: 3! = 3 x 2 x 1 = 6
Therefore, there are six possible schedules for three processes to be scheduled on a single processor. These schedules can be listed as follows: P1 P2 P3 P1 P3 P2 P2 P1 P3 P2 P3 P1 P3 P1 P2 P3 P2 P1.

The formula for the total number of possible schedules is given by n factorial, or n!Where n represents the number of processes to be scheduled on a single processor.

A CPU-scheduling algorithm determines an order for the execution of its scheduled processes. The CPU executes each process according to its order in the queue.

The CPU scheduler selects a process from the ready queue and dispatches it to the CPU for execution.The number of possible schedules for n processes on a single processor is calculated by the factorial function. The factorial function is a mathematical function that multiplies a number by all the positive integers less than it.

Mathematically, we can represent the factorial of n as n! and it can be computed as:n! = n * (n - 1) * (n - 2) * ... * 3 * 2 * 1

Therefore, the total number of possible schedules for n processes on a single processor is given by n factorial or n!.

\(\dot m_{in} = \frac{\dot V_{in}}{\nu_{in}}\) (2)

Voltage, also known as electric potential difference, is a measure of the electrical potential energy per unit of charge in an electrical circuit. It is defined as the amount of work required to move a unit of electric charge between two points in a circuit, typically measured in volts (V).

Three-phase power is needed because it allows for more power to be transmitted over a given amount of wire or cable. With three-phase power, the power is delivered in a more consistent manner, which means that there is less voltage drop over long distances.

2. In order for a three-phase system to be balanced, the three phases must have the same amplitude and be 120 degrees out of phase with each other. The voltage equation of a balanced three-phase voltage source is given by:

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows:  $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$

Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.

The algorithm provided correctly generates T using a random number generator and the exponential distribution formula. It is mathematically proven and ensures that Y is uniformly distributed over the interval (0, 1) when X is uniformly distributed over the same interval.

To generate T given a random number generator of a random variable X uniformly distributed over the interval (0,1), follow the steps below:

Algorithm to generate T

Here, λ is the rate parameter of the exponential distribution represented by T.This algorithm for generating T is correct and can be proved mathematically as follows:

Proof:

First, we will find the cumulative distribution function (CDF) of T. We know that T is exponentially distributed with parameter λ. Hence, the CDF of T is given by: F(t) = P(T ≤ t) = ∫0t λe^(-λt) dt = 1 - e^(-λt)

Now, let's find the inverse of the CDF. Since 0 < X < 1, we have: P(T ≤ t) = X

Therefore, we have:1 - e^(-λt) = X e^(-λt) = 1 - X -λt = ln(1 - X)

Thus, the inverse of the CDF is given by:T = - ln(1 - X)/λ

Now, we need to show that Y is uniformly distributed over the interval (0, 1) if X is uniformly distributed over the interval (0, 1).

Since X is uniformly distributed over the interval (0, 1), its CDF is given by: F(x) = x for 0 ≤ x ≤ 1

Let's find the CDF of Y. Since Y = F(T), we have: P(Y ≤ y) = P(F(T) ≤ y) = P(T ≤ F^-1(y))= F(F^-1(y))= y

Thus, the CDF of Y is: F(y) = y for 0 ≤ y ≤ 1

Hence, Y is uniformly distributed over the interval (0, 1) if X is uniformly distributed over the interval (0, 1).
