D. integrated development environment
Explanation:
Given that an integrated development environment is a form of computer software App that allows the users or programmers to develop a software App in a way the enables them to carry out different operations including source code development, build and test automation, and debugging activities.
For example NetBeans, Eclipse, IntelliJ, and Visual Studio.
Hence, in this case, the correct answer is "integrated development environment."
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) Unsupervised Data mining
Explanation:
Unsupervised data mining also refered to as undirected data mining reveals hidden patterns in unlabeled data. In this method, there are no output variables to predict. The aim of an unsupervised data mining technique is to uncover patterns in data based on the relationship between the data points and each other
