Answer:
True
Explanation:
The class Math include mathematical functions such as sin(), cos(), tan(), abs(), etc
If the given statement is not written, each of the math function will be written as (take for instance, the sin() function):
<em>Math.sin()</em>
<em></em>
But after the statement has been written (it implies that the Math library has been imported into the program) and as such each of the mathematical function can be used directly.
So instead of <em>Math.sin(), </em>you write <em>sin()</em>

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
