Question 9

A full tank contains 8.90 ft.3 of helium, enough to fill 30 balloons.

To calculate the amount of helium needed to fill 50 balloons, first determine the unit rate, which can be calculated as 308.90. Next, create an equation to represent the relationship between h, the volume of helium, and b, the number of balloons: _[blank 1]_. Finally, plug in 50 for b and solve. The amount of helium needed is _[blank 2]_.

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.
