Answer:
Can you take a screenshot of the question becuase I don't think theres enough information.
You add 12 and 6 up and then multiply that result by 1/2, so your answer would be 9.
Answer:
the curse of dimensionality
Step-by-step explanation:
the cause of dimensionality has to do with the different phenomena that comes up whenever data is to be analyzed or organized in high dimensional spaces which do not happen in low dimensional spaces. This curse can be explained simply as having error increase just as there are increases in the number of features. when the features we have is more than the observations, it could cause the model to be overfitted.
Given:
Standard error = 4
Population standard deviation = 16
To find:
The value of n.
Solution:
The formula of standard error is:
Where, SE is standard error , 
is population standard deviation and n is the total number of elements.
Substituting 
in the above formula, we get
Taking square on both sides, we get
Therefore, the value of n is 16.
