Answer is given below :
Step-by-step explanation:
- Histograms are used in group frequency parameters. Furthermore, it is useless as a given set of five parameters or data and only results in a bar graph and, basically, the vertical graph mentioned above is the correct choice to display the numbers.
- It is used to expand on the definition of the histogram when the frequency is grouped. For example, data sets 1–5, 6–10, 11–15 and 16–20 can now be used to describe histograms due to the given number and size of data.
the answer is 39 because you need to divide.
Answer:
22 miles per hour
Step-by-step explanation:
Against the current, the boat's rate of travel is ...
(120 mi)/(6 h) = 20 mi/h
With the current, the boat's rate of travel is ...
(120 mi)/(5 h) = 24 mi/h
___
The sum of boat speed (b) and current speed (c) is 24 mph. The difference is 20 mph. This lets us write the equations ...
b + c = 24
b - c = 20
Adding these two equations together, we get ...
2b + 0c = 44
b = 22 . . . . . . . . divide by 2
The rate of the boat in still water is 22 miles per hour.
