ray was in charge of filling the soccer team’s water jug for practice. at the beginning of practice he filled the jug. halfway through practice the team took a water break. after the break ray refilled the jug so the players could have water after practice. at the end of practice ray drained the jug. which graph could represent the level of the water in the jug during and after practice?

The third graph.

Step-by-step explanation:

Before practice, the jug was empty.  This means it starts at 0.  Ray fills the jug up; this will be the graph increasing, starting at 0, until the jug was filled.

The jug stays at the same level during practice; this means the graph will be constant during this time.

Halfway through practice the players drink from the jug.  During this time the graph will be decreasing.

Ray then fills the jug back up; this means the graph will increase.

During the rest of practice, the jug stays at the same level; the graph will be constant during this time.

After practice Ray drains the jug.  This means the graph will decrease during this time.

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.
