<u>Answer:</u>

The correct answer option is D. 0.42.

<u>Step-by-step explanation:</u>

We are given the results of a survey in which people were asked if they prefer reading books or e-books.

We are to find the marginal frequency of the number of people who prefer to read books.

For that, we will divide the total number of people who prefer reading books by the total number of people surveyed.

Marginal frequency = 105/250 = 0.42

Test each statement below to see if it is reversible. If so, write it as a true biconditional. If not, write not reversible
FinnZ [79.3K]
Statement: Complementary angles are two angles with measures that have a sum of 90.
Reverse: Two angles with measures that have a sum of 90 are complementary angles.

Here the reverse is true, therefore, the statement is true biconditional.

Statement: A rectangle is a four-sided figure with at least one right angle.
Reverse: A four sided figure with at least one right angle is a rectangle.

Here, the reverse is not true, therefore, the statement is not reversible.
