Represents the sets with a venn diagram: u = {1,2,3,4,5,6,7,8,9,10, 11, 12} a = {1,2,3,4,6, 12} b = {1,2,4,8}

The required figure is shown below

Step-by-step explanation:

Consider the provided sets:

U = {1,2,3,4,5,6,7,8,9,10,11,12}

A = {1,2,3,4,6, 12}

B = {1,2,4,8}

We need to draw the Venn diagram.

Draw a rectangle which represents set U.

Now, Make circles for set A and set B. Every circle should overlap.

Write the element of each set as shown in figure.

Place elements inside each circle which represents the elements of corresponding sets.

Place common element of set in the section in which all circles shapes overlap.

The required figure is shown below

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
