Answers
The probability of a player having an accuracy less than 30% is 0.0324, and the probability of a player having an accuracy greater than 90% is 0.0097.
To answer this question, we need to use the Graph Builder in JMP to create a histogram of the "Penalties" variable. Then, we can use the histogram to find the number of players with an accuracy less than 30% and the probabilities of players having an accuracy less than 30% and greater than 90%.
1. Open the "FIFA_Data" data set in JMP.
2. Click on the "Graph Builder" icon in the toolbar.
3. Drag the "Penalties" variable to the x-axis.
4. Click on the "Histogram" option at the top of the Graph Builder window.
5. The histogram will be displayed, showing the distribution of the "Penalties" variable.
To find the number of players with an accuracy less than 30%, we need to look at the histogram and count the number of players in the bins that are less than 30. In this case, there are 570 players with an accuracy less than 30%.
To find the probabilities of players having an accuracy less than 30% and greater than 90%, we need to divide the number of players in each of these categories by the total number of players. The total number of players is 17,588.
P(less than 30%) = 570 / 17,588 = 0.0324 (rounded to 4 decimal places)
P(greater than 90%) = 171 / 17,588 = 0.0097 (rounded to 4 decimal places)

Air enters an adiabatic gas turbine at 1590 oF, 40 psia and leaves at 15 psia. The turbine efficiency is 80%, and the mass flow rate is 2500 lbm/hr. Determines:
a) The work produced, hp.
b) The exit temperature, oF.
Answers
Answer:
a) 158.4 HP.
b) 1235.6 °F.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to set up an energy balance for the turbine's inlets and outlets:
\(m_{in}h_{in}=W_{out}+m_{out}h_{out}\)
Whereas the mass flow is just the same, which means we have:
\(W_{out}=m_{out}(h_{out}-h_{in})\)
And the enthalpy and entropy of the inlet stream is obtained from steam tables:
\(h_{in}=1860.7BTU/lbm\\\\s_{in}= 2.2096BTU/lbm-R\)
Now, since we assume the 80% accounts for the isentropic efficiency for this adiabatic gas turbine, we assume the entropy is constant so that:
\(s_{out}= 2.2096BTU/lbm-R\)
Which means we can find the temperature at which this entropy is exhibited at 15 psia, which gives values of temperature of 1200 °F (s=2.1986 BTU/lbm-K) and 1400 °F (s=2.2604 BTU/lbm-K), and thus, we interpolate for s=2.2096 to obtain a temperature of 1235.6 °F.
Moreover, the enthalpy at the turbine's outlet can be also interpolated by knowing that at 1200 °F h=1639.8 BTU/lbm and at 1400 °F h=174.5 BTU/lbm, to obtain:
\(h_{out}=1659.15BUT/lbm\)
Then, the isentropic work (negative due to convention) is:
\(W_{out}=2500lbm/h(1659.15BUT/lbm-1860.7BUT/lbm)\\\\W_{out}=-503,875BTU\)
And the real produced work is:
\(W_{real}=0.8*-503875BTU\\\\W_{real}=-403100BTU\)
Finally, in horsepower:
\(W_{real}=-403100BTU/hr*\frac{1HP}{2544.4336BTU/hr} \\\\W_{real}=158.4HP\)

Answers
1. The equivalent capacitance between terminals a-c is 2.4 μF
2. The equivalent capacitance between terminals b-c is 6μF
3. The equivalent capacitance between terminals c-d is 12 μF
What is a capacitance?Capacitance is the ability for a device to store charge
1. How to find the equivalent capacitance betwee terminals a-c?Given that the capacitance bewteen terminals a-c = a-b + b-c
Now, the capacitance between terminals b-c are in parallel.
So, for capacitances in parallel, we add their capacitances to get the equvalent capacitance.
So, the equivalent capapcitance between b-c is C = 1 μF + 2μF + 3µF = 6μF
Now C is in series with the capapcitance between terminals a-b.
Since they are in series, their equivalent capapcitance C' is
1/C' = 1/4μF + 1/C
= 1/4μF + 1/6μF
= (3 + 2)/12 μF
1/C' = 5/12 μF
C' = 12/5 μF
= 2.4 μF
So, the equivalent capacitance between terminals a-c is 2.4 μF
2. How to find the equivalent capacitance betwee terminals b-c?To find the equivalent capacitance between terminals b-c, we see that the capacitance between terminals b-c are in parallel.
So, for capacitances in parallel, we add their capacitances to get the equvalent capacitance.
So, the equivalent capapcitance between b-c is C = 1 μF + 2μF + 3µF = 6μF
So, the equivalent capacitance between terminals b-c is 6μF
3. How to find the equivalent capacitance betwee terminals c-d?Since there is only one capacitor between terminals c-d, the equivalent capacitance is equal to the value of that capacitor which is 12 μF

Answers
To simulate a three-way crossover system in SPICE, you will need the circuit schematic or diagram of the crossover network, including the component values for each filter section. With that information, you can create a SPICE netlist that represents the circuit and use a SPICE simulator, such as LTspice or Ngspice, to perform the simulations.
Here are the general steps to simulate a three-way crossover system using SPICE:
Create the circuit schematic: Design the three-way crossover network with the desired filter characteristics for each section. This typically involves using specific filter topologies such as Butterworth, Linkwitz-Riley, or Bessel filtersAssign component values: Determine the appropriate component values for each filter section based on the desired cutoff frequencies and filter orders. This includes selecting suitable resistors, capacitors, and inductorsCreate the SPICE netlist: Convert the circuit schematic into a SPICE netlist format. Define the components (resistors, capacitors, inductors), their values, and connections between themDefine the input signal: Specify the input signal for the simulation. This can be a sine wave or any other waveform you wish to useRun the simulation: Use the SPICE simulator to run the simulation. Set the desired frequency range (10 Hz to 100 kHz) and obtain the output waveforms for each filter sectionAnalyze the results: Extract the magnitude and phase information from the simulation results for each filter section. Plot the results using a tool of your choice, such as MATLAB or a dedicated plotting software.To generate Bode plots, you can plot the magnitude and phase response of each filter section individually. For the combined magnitude plot, add the output voltages of the three filter sections together (in decibels) versus frequency. Similarly, for the combined magnitude plot in linear volts, add the output voltages of the three filter sections together (in linear scale) versus frequency.

Answers
The rate of heat transfer through the wall is approximately 130 W.
No, we cannot ignore the steel bars between the plates in the heat transfer analysis because they contribute to the overall thermal resistance of the wall.
While they may only occupy a small percentage of the heat transfer surface area, they still have an impact on the rate of heat transfer through the wall.
By including the thermal resistance of the steel bars in the analysis, we can obtain a more accurate estimate of the heat transfer rate.
To calculate the heat transfer rate, we can use the formula Q = (kAΔT)/d, where Q is the heat transfer rate, k is the thermal conductivity, A is the area of heat transfer, ΔT is the temperature difference, and d is the thickness of the wall.
By applying this formula to the given data, we can calculate that the rate of heat transfer through the wall is approximately 130 W.

A 30-g bullet is fired with a horizontal velocity of 450 m/s and becomes embedded in block B which has a mass of 3 kg. After the impact, block B slides on a 30-kg carrier C until it impacts the end of the carrier.Knowing the impact between B and C is perfectly plastic determine (a) velocity of the bullet and B after the first impact, (b) the final velocity of the carrier
(Distance between C and B is 0.5 m)
Answers
Answer:
a.) 4.46 m/s
b.) 0.41 m/s
Explanation:
a) Given that the mass M of the bullet = 30g = 30/1000 = 0.03 kg
Velocity V = 450 m/s
From conservative of linear momentum,
Sum of momentum before impact = Sum of momentum after impact
0.03 × 450 = (0.03 + 3 ) × v₂
v₂ = 13.5/3.03 = 4.4554 m/s
Therefore the velocity of the bullet and B after the first impact = 4.46 m/s approximately
(b) To calculate the velocity of the carrier, you will consider the conservation of linear momentum again.
(m₁ + m₂)×v₂ = (m₁ + m₂ + m₃)×v₃
Where:
Mass of the carrier m₃ = 30 kg
Substitute all the parameters into the formula
3.03×4.4554 = (3.03 +30) × v₃
v₃ = 13.5 / 33.03 = 0.40872 m/s
Therefore the velocity of the carrier is 0.41 m/s approximately.

The maximum profit is 72450 where 240 economy tickets are purchased and 30 tickets are business class tickets.
Given that:
An airline company offers business and economy class tickets.
The airline makes a profit of SAR 245 for each economy ticket and SAR 455 for each business-class ticket.
So, if x represents the number of economy tickets and y represents the number of business tickets:
Maximize z = 245x + 455y
Now, x ≥ 70 and y ≥ 30
The plane has a capacity of 300 normal chairs (economy class); however, each business class chair is double the space of a normal chair.
So, x + 2y ≤ 300
(a) So an LP can be formulated as:
Maximize z = 245x + 455y subject to the constraints:
x + 2y ≤ 300
x ≥ 70
y ≥ 30
(b) Draw a coordinate plane.
x ≥ 70 is a solid vertical line passing through (70, 0). The region is right to the line.
y ≥ 30 is the solid horizontal line passing through (0, 30), The region is the upside of the line.
x + 2y ≤ 300 is a line passing through (0, 150) and (300, 0).
The feasible region contains the region where all the constraints are satisfied.
The corner points of the feasible region are thus (70, 115), (240, 30), and (70, 30).
Find the value of z for these points.
At (70, 115), z = 69475
At (240, 30), z = 72450
At (70, 30), z = 30800
Hence the maximum profit is at (240, 30) of 72450.

According to the tds relations, the specific entropy change of air when it is heated from t1 to t2 while executing an isobaric process is:_____.
Answers
During an isobaric process, the pressure of the system remains constant. The specific entropy change (Δs) of air can be calculated using the equation:
Δs = Cp * ln(t2/t1)
Where Cp is the specific heat at constant pressure. In this case, since the process is isobaric, Cp remains constant. Therefore, the specific entropy change is directly proportional to the natural logarithm of the ratio of the final temperature (t2) to the initial temperature (t1).
This means that regardless of the actual values of t1 and t2, the specific entropy change during an isobaric process will always be the same. The specific entropy change is solely determined by the ratio of the temperatures and does not depend on the actual values of the temperatures themselves.

Answers
An X-ray machine is installed with a long-time rating based on an operating interval of 517.2 minutes or longer. This means that the X-ray equipment is designed to operate safely and effectively for periods of 517.2 minutes (about 8.6 hours) or longer without experiencing issues related to its performance or safety.
X-rays, or less commonly X-rays, are high-energy electromagnetic radiations. Most X-rays have wavelengths in the 10 picometers to 10-nanometer range and energies in the 145 eV to 145 range, corresponding to frequencies in the 30 petahertz to 30 Ahtz (3 × 1016 Hz to 3 × 1019 Hz) range. house. Kev. X-rays have shorter wavelengths than ultraviolet rays and generally longer wavelengths than gamma rays. X-rays are called X-ray radiation in many languages and are named after German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. Send out an unknown type of radiation is called an X-ray. The English X-ray notation includes the lines x-ray(s), xray(s), and X-ray(s).

Car A is traveling at 25 mi ∕hr and applies the brakes
at the position shown so as to arrive at the intersection C at
a complete stop with a constant deceleration. Car B has a
speed of 40 mi ∕hr at the instant represented and is capable
of a maximum deceleration of 18 ft ∕sec2
. If the driver of car B
is distracted and does not apply his brakes until 1.30 seconds after car A begins to brake, the result being a collision
with car A, with what relative speed will car B strike car A?
Treat both cars as particles.
Answers
Therefore, the relative speed at the time of collision is 17.8816 mps
How do we calculate?We will use the equation of motion:
v^2 = u^2 + 2as
s = (v^2 - u^2) / 2a
s = (0 - (25)^2) / (2a)
s = 312.5 / a
The distance the Car B travels during the 1.30 seconds when its driver is distracted and does not apply the brakes is gotten as
S = ut + (1/2)at^2
s = (17.8816 mps)(1.30 sec) + (1/2)(-5.4864 m/sec^2)(1.30 sec)^2
s = 11.645 m
The relative speed at the time of collision is:
(40 mph - 0 mph) * 1.60934 kmph * 1000 m/km / 3600 sec/hour = 17.8816 mps
Car B will only travels at 11.645 m before hitting Car A which is clear indication that Car B will not be able to stop in time and a collision will occur.
