Answer:
Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is
Explanation:
The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."
This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.
Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.
And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters
```
#!/usr/local/bin/python3
import sys
def print_factorial( user_val ):
if( user_val < 1 ):
return( 1 )
else:
return( print_factorial( user_val - 1 ) * user_val )
if( __name__ == "__main__" ):
if( len( sys.argv ) == 2 ):
print( print_factorial( int ( sys.argv[ 1 ] ) ) )
else:
sys.stderr.write( "usage: %s <integer>\n" % sys.argv[ 0 ] )
exit( 0 )

Answer:
Use the HLOOKUP function in the cell E2 by specifying the student's hourly rate value, the range of cells of the table holding the information, the row from which to return the value, and a value of true or false for approximate or exact match respectively.
Explanation:
Microsoft Excel is a statistics tool used for data analysis. It has several functions and graphical properties for cleaning and representing data.
The HLOOKUP function is an example of a search function in excel, it returns a value based on another value from a range of cells. The function accepts four arguments, they are, the value to be searched, the range table or cell range to search, the row to get the search value, and a mode of return value to return, could be either true for an approximate match or false for an exact match.
Answer:
The phenomenon of total internal reflection of light is used in many optical instruments like telescopes, microscopes, binoculars, spectroscopes, periscopes etc. The brilliance of a diamond is due to total internal reflection. Optical fibre works on the principle of total internal reflection.

thank me later but if it wrong. sorry
