Records for the first one and table for the second one
Answer:
snap
Explanation:
The line which appears when we are dragging an object of GUI on a object of windows Form indicates that the object that is being dragged is aligned horizontally with the object which is connected by the blue line is called a snap line.
Hence we conclude that the answer to this question is snap line.
Answer:
- import math
-
- def standard_deviation(aList):
- sum = 0
- for x in aList:
- sum += x
-
- mean = sum / float(len(aList))
-
- sumDe = 0
-
- for x in aList:
- sumDe += (x - mean) * (x - mean)
-
- variance = sumDe / float(len(aList))
- SD = math.sqrt(variance)
-
- return SD
-
- print(standard_deviation([3,6, 7, 9, 12, 17]))
Explanation:
The solution code is written in Python 3.
Firstly, we need to import math module (Line 1).
Next, create a function standard_deviation that takes one input parameter, which is a list (Line 3). In the function, calculate the mean for the value in the input list (Line 4-8). Next, use the mean to calculate the variance (Line 10-15). Next, use sqrt method from math module to get the square root of variance and this will result in standard deviation (Line 16). At last, return the standard deviation (Line 18).
We can test the function using a sample list (Line 20) and we shall get 4.509249752822894
If we pass an empty list, a ZeroDivisionError exception will be raised.
The main drawback of multiuser processing of a database is:
<h3>What is lost-update problem?</h3>
In the area of lost update problem, an update that has been carried on to a data item by a transaction is said to be lost as it is known to be overwritten by the update that has been carried on by another transaction.
