Answer: The difference between the scope and linkage is as follows:-
- Scope of the variable is defined as the variable view from different program parts whereas the linkage is described as the link that is made between the variable and the declaration function having the common name.
- Scope of variable describes about the existing time of the variable in the program whereas linkage is defined for the name of variable present in the program is available at all time .
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 )
Answer:
d) consumer misbehavior
Explanation:
This is an example of consumer misbehavior. What Lena is doing is not technically piracy or illegal because HBO has created the family feature on their accounts for the account to be used by multiple people at the same time. Yet, the feature was not intended to be used by individuals that are not technically family or even under the same roof. Therefore, what Lena is doing goes against HBO's reason for this feature and sharing the account as Lena is doing is ultimately hurting HBO's streaming service.
Answer:
A variable is a name associated with a data value; we say that the variable "stores" or "contains" the value. Variables allow us to store and manipulate data in our programs.
