Jamie recorded the time it took 25 students to complete a mathematics
test. She created a histogram and a stem-and-leaf plot to represent the
data. To determine the median of the data set, Jamie analyzed the-
a) histogram because it showed each value in the set of data
b) stem-and-leaf-plot because it showed each value in the set of data
c) histogram because the median is always the bar with the greatest
height
d) stem-and-leaf-plot because the median is always the "leaf" that
appears most often

b) stem-and-leaf-plot because it showed each value in the set of data

Step-by-step explanation:

First let's clarify the concept of median, the median is the average value of a sample of data, that is, the data of half.

Now, a histogram is a graph of frequency, therefore although it organizes the data from highest to lowest, we will see the number of times in this case the age is repeated in a certain range.

For its part, stem-and-leaf-plot shows each data of the sample in an organized way, therefore it will be easier to find the data of half.

In other words, the correct answer is b.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
