Which stems would you use to plot the data? 19, 18, 23, 24, 31, 32, 16

The stems used to plot the data are 1, 2 and 3

Step-by-step explanation:

Stems and leaf plot is a method of representing datas of a series where each data value is represented by stem as its first digit (digits) and leaf as its final digit(digits).

In the given table since all the data values has two digits therefore for plotting stems we have to find the largest and smallest number at the tenth place in the given data series.

Data series is:

19, 18, 23, 24, 31, 32, 16

Smallest number at tenth place = 1

largest number at tenth  place = 3

So the stems used to plot the data are 1, 2 and 3

Stem-leaf plot is shown in table 1 below:

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
