(4)Two or more sets are disjointed if they have some elements in common True/False (5) In the given ratio b:c, b is known as the antecedent True/False (6) Array is the arrangement of numerical data in order of magnitude True/False (7) Secondary source of data are eye witness, accounts, reports or recoded Observation True/False

<p> <br />4. The statement is incorrect. Two or more sets are said to be disjoint if they have no elements in common. In other words, the intersection of disjoint sets is the empty set.<br /> <br />5. The statement is correct. In a ratio \( b:c \), \( b \) is known as the antecedent and \( c \) is known as the consequent. The antecedent is the first term in the ratio, and the consequent is the second term.<br /> <br />6. The statement is incorrect. An array is a data structure that can hold more than one value at a time, but it does not necessarily have to be arranged in order of magnitude. Arrays can hold numerical data, characters, or other types of data, and the arrangement can be arbitrary unless specifically sorted.<br /> <br />7. The statement is incorrect. Secondary sources of data are not eye-witness accounts, reports, or recorded observations. Secondary data sources are data that were collected by someone other than the user, often for some other purpose. These can include reports, surveys, and other data that have been collected and archived.<br /></p>
