What is the sum of the frequencies in a frequency table?
Multiply the number of, for example, pets, to its frequency. After you get the product, add all of those products up.E.g.:Number of pets:Frequency1:82:63:34:25:06:1(1*8) + (2*6) + (3*3) + (4*2) + (5*0) + (6*1)= 8 + 12 + 9 + 8 + 0 + 6 = 43.The sum is 43.

How is a bar graph and dot plots similar?
A dot plot is similar to a bar graph because they both can give you the same amount of pets and other things that you might use them for.
Which question requires the collection of data to answer it?

What is the difference between a bar graph and a line plot?
The difference is that there is no y axis on a line plot. The letter X is used to represent one of that number. For example, if there where 2 people that had two pets, there would be two Xs above the number 2. A bar graph uses the scale on the y axis to tell you the amount, instead of Xs. I hope this helps!
