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

Complete Question:
Which of the following is a trademark automatically received by an organization when a symbol is being consistently used in the normal course of business?
Group of answer choices
A. Open source trademark.
B. Common law trademark.
C. Registered trademark.
D. Open source trademark.
Answer:
B. Common law trademark.
Explanation:
A common law trademark can be defined as a protection or enforceable mark for a product name, logo, symbol or brand name used to distinguish goods and services prior to its registration with the state or federal government. Common law trademark is a trademark which is automatically received by an organization when a symbol is being consistently used in the normal course of business.
This ultimately implies that, common law trademarks are not governed by any statute and as such are only limited to the geographical location where they are used.
For instance, if a tomato paste is being sold to consumers with the product name "Ginoo" in Florida, the company's trademark applies to Florida only. Thus, another company can use the product name without any trademark infringement in other states of the country such as New York, Washington DC, California etc. except in Florida due to a common law trademark.
Answer:
ALTER TABLE orders
MODIFY (amount DEFAULT 250)
Explanation:
- ALTER TABLE statement is used to modify "amount" column in the existing "orders" table
- MODIFY (amount DEFAULT 250) is used to set the default value 250 of the "amount" column.
Therefore if the supervisor wants the amount column to be configured to accept a default value of 250, then "ALTER TABLE orders MODIFY (amount DEFAULT 250) " statement should be issued.
