A bar graph is when you want to compare the data in the data set (which this data set does)
A line graph is used when the data set creates a straight line (which this data set does not)
A circle graph (also known as a pie chart) is used when the data set measures percentages that will total 100% (which this data set does not)
A stem plot is used when you want to show the frequency of the beginning digit <em>or digits</em> (which this data set does not)
Answer: A
Answer:
16 years old
Step-by-step explanation:
The age of his sister = 12 years old
Gasta is 4 years older than his sister,
The age of Gasta
= 4 + 12
= 16 years old.
Therefore,
Gasta is 16 years old.
When we are looking for the mid point, we are looking for a point that is an equal distance from point R and S.
Since the x value has no change, we can ignore it.
For the y value, we want to simply find the difference between the points (7 - 1 = 6) and then divide that value by 2 (6 / 2 = 3).
You can then subtract that value from the higher Y value, where you will get 4.
Leaving you with the coordinate (3,4)
Hope this helped. There are definitely more ways you could find to solve this, but this works best for this problem.

Answer:
For the Chinese students the mean is 6.8 and the median is 7. The mode is 6 and the range is 5.
Step-by-step explanation:
The mean is just the Sum of all the number on the left columns divided by the number students. The sum is 204 and there are 30 students. So divide 204 by 30 and you get 6.8.
To find the median for Chinese students, all you need to do is arrange the numbers from least to greatest and then find the number,or numbers, that are left in the middle. So you cross off numbers on both ends until you get to the middle. Ex: you are given the numbers 12,7, and 5. Arrange them like so, 5, 7, 12. cross off the numbers on the sides and you get 7 as your median. Because 30 is divisible by 2, you end up with two numbers in the middle. When that happens, you add both middle numbers together and then divide by 2.
Finding the mode shouldn't be too hard if you've arranged the numbers from least to greatest. The mode is just the number you see most often in a set of data. In this case, 6 is the most common number of letters a Chinese student has.
Lastly, to find the range, you need to find the lowest value or number and subtract it from the highest value or number. Here the highest value is 9 and the lowest is 4. So 9 - 4 = 5.
