The answer would be true.
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
Answer:
Option B is the correct answer for the following question.
Explanation:
The following option is true because the pearsonr from scipy module is the method of the Python Programming Language in the submodule i.e., "scipy.stats" which print or return P-value for operating the hypothesis test for the value of correlation coefficient. So, that's why the following option is correct.
