1) select the hypothesis of the conditional statement.
if you walk to the movie theater, then you will arrive late.

2) use the conditional statement to answer the question.

if you live in san diego, then you live in california.

what is the converse of the statement?

if you live in san diego, then you do not live in california.

if you live in california, then you live in san diego.

if you do not live in san diego, then you do not live in california.

if you do not live in california, then you do not live in san diego.

3) use the conditional statement to answer the question.

if a whole number is even, then the number is divisible by 4.

are the statement and its converse true?

both the statement and its converse are false.

the statement is false, but the converse is true.

the statement is true, but the converse is false.

both the statement and its converse are true.

4) use the conditional statement to answer the question.

if today is monday, then yesterday was sunday.

can the statement be written as a biconditional statement and why?

no, because the statement is false, but its converse is true

no, because the statement is true, but its converse is false

yes, because the statement and its converse are both true

no, because the statement and its converse are both false

5)is each biconditional statement true or false?

select true or false for each statement.
true false

1. In a conditional statement, there are two parts: the hypothesis and the conclusion. In the given statement, the hypothesis is: If you walk to the movie theater.

2. The converse of the statement is when you interchange the hypothesis and conclusion. In this case, the converse of the given statement is: If you live in California, then you live in San Diego.

3. The given statement is correct, because if that were true, 2 should be divisible by 4. However, it is not. However, the converse statement is true, because if the number is divisible by 4, it is given that the number is even. Thus, the answer is: The statement is false, but the converse is true.

4. The statement can be biconditional, if both the original and the converse statements are true. However, only the original statement is true. Thus, the answer is: No, because the statement is true, but its converse is false.

5. The answers are:
a.) True
b.) False, because the shape with four sides is a quadrilateral. For it to be square, the four sides must be equal.
c.) True
d.) False, a shape with four sides is a quadrilateral and not exactly a reactangle. It would only be a rectangle if two sets of sides are equal.

the results from a pre-test for students for the year 2000 and the year 2010 are illustrated in the box plot. what do these results tell us about how students performed on the 29 question pre-test for the two years?

if we compare only the lowest and highest scores between the two years, we might conclude that the students in 2010 did better than the students in 2010. this conclusion seems to follow since the lowest score of 8 in 2010 is greater in value than the lowest score of 6 in 2000. also, the highest score of 28 in 2010 is greater in value than the highest score of 27 in 2000.

but the box portion of the illustration gives us more detailed information. the middle bar in each box shows us that the median score of 20 in 2000 is greater in value than the median score of 17 in 2010. further, we note that the box and whiskers divide the illustration into four pieces. each of these four pieces represents the same portion of students. so, the upper half of the students in 2000 scored in the same score range as the upper one-fourth of the students in 2010, see the illustration at a score of 20.

by considering the upper one-fourth, upper half, and upper three-fourths instead of just the lowest and highest scores, we would conclude that the students as a whole did much better in 2000 than in 2010. we would conclude that as a whole the students in 2010 are less prepared than the students in 2000.

in this section, we discuss box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. the key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
