Answer:
Simplex transmission
Explanation:
Communication between computer and keyboard involves which transmission? Answer: Simplex transmission requires communicating between a computer and a keyboard. The simple transmission & communication channel allows data from only one direction.

Answer:
The correct answer to the following question will be "Abstract Reasoning".
Explanation:
- Abstract reasoning depends on the ability to interpret facts, to identify correlations and interactions and to resolve the problems at a deep, conceptual level.
- To be able to construct hypotheses about both the existence of events and concepts require abstract reasoning capabilities.
This suggests, therefore, that Dallas has this ability.
Answer:
String word = "George slew the dragon";
int pos = word.indexOf("dr");
String drWord = word.substring(pos, pos+4);
System.out.println(drWord);
Explanation:
Assuming dr is always there, we don't have to check the validity of 'pos'. Normally, you would!
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) =
=
= 0.0316
For x = 120, sample proportion(p) =
=
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z <
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
