Answer:
(a) 0.12924
(b) Taking into consideration significance level of 0.05 yet the value of p is greater than 0.05, it suggests that the coin is fair hence the coin can be used at the beginning of any sport event.
Explanation:
(a)
n=200 for fair coin getting head, p= 0.5
Expectation = np =200*0.5=100
Variance = np(1 - p) = 100(1-0.5)=100*0.5=50
Standard deviation,
Z value for 108,
P( x ≥108) = P( z >1.13)= 0.12924
(b)
Taking into consideration significance level of 0.05 yet the value of p is greater than 0.05, it suggests that the coin is fair hence the coin can be used at the beginning of any sport event.
Answer:
ALL CAREFULLY ANSWERED CORRECTLY
Explanation:
1) A loaf of Bread PHYSICAL SYSTEM
✓ How can the environment affect the edibility of the bread
✓ What are the constituents that makes up the bread
✓ What process is involved in these constituents mixing to form the loaf.
2) The law of thermodynamics makes us to understand that when heat/energy passes through a system, the systems internal energy changes with respect to the conservation of energy law. That is energy lost = energy gained. Typically, ice would melt in a cup of hot tea because of the thermal energy in the molecules of the hot tea. When you heat a material, you are adding thermal kinetic energy to its molecules and usually raising its temperature. The temperature of the ice raises due to the kinetic energy added to it and it melts to water.
3) The theory of systems view the world as a complex system of interconnected parts. If we consider the society; (financial systems, political systems, etc) we will agree that they individually have their own components and it's the summation of this components that makes the system, this implies that system thinking could be applicable in this kinda of systems as long as they are made up of components.
4) Technology has boosted every sector of our lives and it has the capacity to do more. Restricting it's importance to entertainment alone would be an underusing of its potentials. Engineering students infact should not need any drive to be encouraged about maximizing all it can do in shaping our world.
5) ~ Nature shows its splendid soul
~Never ceases to leave us in amazement
~And we are in love
Answer: Manufacturing engineers may be responsible for solving production problems, conducting cost-benefit assessments, or designing and manufacturing goods and systems using computer-aided design software. Plant engineers and process engineers are two terms used by professionals in this industry. Manufacturing engineers are in charge of new and existing production lines' technical management, maintenance, and development. Employers are looking for people that are commercially aware and have good technical and analytical skills. They are in charge of keeping production costs low while preserving the product or service's quality, and they have considerable project expertise and insight.
Explanation: See above.

Answer:
<em>T = 25.41 Nm</em>
Explanation:
Calculating Nsync (Synchronous Speed):



Calculating s (Slip):
![s = (Nsync - Nm) / Nsync \\[tex]s = (3600-2464)/3600\\s = 0.3156](https://tex.z-dn.net/?f=s%20%3D%20%28Nsync%20-%20Nm%29%20%2F%20Nsync%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Btex%5Ds%20%3D%20%283600-2464%29%2F3600%5C%5Cs%20%3D%200.3156)
Calculating Vth (Thevenin Voltage):

Calculating Rth (Thevenin Resistance):
Calculating Xth (Thevenin Reactance):
Xth = Xs = 1.3 ohm
Calculating Torque:
![T = (3Vth^{2}Rr/s) / (Wsync[(Rth+Rr/s)^{2} + (Xth + Xr)^{2}])\\T = (3*205.39*0.7/0.3156) / 377[(2.22+0.7/0.315)^{2} + (1.3+1.8)^{2}]](https://tex.z-dn.net/?f=T%20%3D%20%283Vth%5E%7B2%7DRr%2Fs%29%20%2F%20%28Wsync%5B%28Rth%2BRr%2Fs%29%5E%7B2%7D%20%2B%20%28Xth%20%2B%20Xr%29%5E%7B2%7D%5D%29%5C%5CT%20%3D%20%283%2A205.39%2A0.7%2F0.3156%29%20%2F%20377%5B%282.22%2B0.7%2F0.315%29%5E%7B2%7D%20%2B%20%281.3%2B1.8%29%5E%7B2%7D%5D)
T = 280699 / 377 [19.69 + 9.61]
<em>T = 25.41 Nm</em>
