The Cricket Board has long recognized John’s potential as a leader of the team. However, his on-field temper has always been a matter of concern for them since his junior days. While this aggression has filled stadia with die-hard fans, it has taken a toll on his own batting. Until recently, it appeared that he found it difficult to convert his aggression into big scores. Over the past three seasons though, that picture of John has been replaced by a cerebral, calculative and successful batsman-captain. After many years, it appears that the team has finally found a complete captain. Which of the following statements can be logically inferred from the above paragraph?
(i) Even as a junior cricketer, John was considered a good captain.
(ii) Finding a complete captain is a challenge.
(iii) Fans and the Cricket Board have differing views on what they want in a captain.
(iv) Over the past three seasons John has accumulated big scores.
A cab was involved in a hit and run accident at night. You are given the following data about the cabs in the city and the accident.
(i) 85% of cabs in the city are green and the remaining cabs are blue.
(ii) A witness identified the cab involved in the accident as blue.
(iii) It is known that a witness can correctly identify the cab colour only 80% of the time. Which of the following options is closest to the probability that the accident was caused by a blue cab?
A coastal region with unparalleled beauty is home to many species of animals. It is dotted with coral reefs and unspoilt white sandy beaches. It has remained inaccessible to tourists due to poor connectivity and lack of accommodation. A company has spotted the opportunity and is planning to develop a luxury resort with helicopter service to the nearest major city airport. Environmentalists are upset that this would lead to the region becoming crowded and polluted like any other major beach resorts.
Which one of the following statements can be logically inferred from the information given in the above paragraph?
Two identical nMOS transistors M_{1} and M_{2} are connected as shown below. The circuit is used as an amplifier with the input connected between G and S terminals and the output taken between D and S terminals. V_{bias} and VD are so adjusted that both transistors are in saturation. The transconductance of this combination is defined as $\style{font-family:'Times New Roman'}{g_m=\frac{\partial i_D}{\partial\nu_{GS}}}$ while the output resistance is $ r_o=\frac{\partial v_{{}_{DS}}}{\partial i_D} $ , where $\style{font-family:'Times New Roman'}{i_D}$ is the current flowing into the drain of M2 . Let $\style{font-family:'Times New Roman'}{g_{m1},\;g_{m2}}$ be the transconductances and $\style{font-family:'Times New Roman'}{r_{o1},\;r_{o2}}$ be the output resistances of transistors M_{1} and M_{2}, respectively
Which of the following statements about estimates for $\style{font-family:'Times New Roman'}{g_m}$ and $\style{font-family:'Times New Roman'}{r_o}$ is correct?
A good transimpedance amplifier has
