Juan wants to find the mode of the data set below.

2, 7, 7, 11, 6, 3, 7, 4, 1, 9, 6, 2, 3, 8, 5, 1

He decides to use a stem and leaf plot to help him, but his teacher tells him that he should consider using a line plot instead. Why is a line plot a better choice than a stem and leaf plot for this set?

A line plot shows all the numbers lined up and will easily show what the mode, or most occurring number is. A stem and leaf plot shows this, but is less clear and is more used for what numbers are.

answer is : muchas/tipicas

have a nice day!

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
