Which type of data would be best displayed in a histogram? a. the number of fluoride treatments given to students each month for the last 60 months (range: 40-620) b. the number of college students from the dental school that volunteered their time last month c. the number of students seen in a school clinic that wore braces d. the number of dental chairs donated each month for the last 12 months (range: 1-9)

The number of fluoride treatments given to students each month for the last 60 months (range: 40-620).

The correct option is A.

A histogram is a chart that shows frequency intervals.

The histogram could be plotted to represent the number of fluoride treatments given to students every month may be graphed with the 60 months on the horizontal axis.

A bar for each month where the height of the bars shows the number of fluoride treatments for the monthlies on the vertical axis.

When the graph is leaner over left or leaner over right.

Hence, the number of fluoride treatments given to students each month for the last 60 months (range: 40-620)

A.The number of fluoride treatments given to students each month for the last 60 months (range: 40-620)

Step-by-step explanation:

Given that the range of flourine treatment is 40 to 420 and the timeframe is 60 months,

An histogram plotted to represent the above will allow visual comparison, in a very easy way, one of which is how the number of treatments vary by month.

Also, the histogram could he plotted to represent the number of fluoride treatments given to students every months may be graphed with the 60 months on the horizontal axis, using a bar for each month where the height of the bars will denote the number of fluoride treatments for the month and will be read on the vertical axis.

The reason highlighted makes it an ideal representation for this kind of data. In other form, it would be harder to compare a set of data for so many months and  whose range is so broad (40 - 620).

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
