Answer: Mean = 7.8
Median = 9
Mode = 2,9
Step-by-step explanation: <u>Mean</u> is the average value of a data set. Mean from a frequency table is calculated as:

E(X) = 7.8
Mean for the given frequency distribtuion is 7.8.
<u>Median</u> is the central term of a set of numbers. Median in a frequency table is calculated as:
1) Find total number, n:
n = 10 + 9 + 10 + 7 + 3 + 4 + 3 = 46
2) Find position, using: 
= 23.5
Median is in the 23.5th position.
3) Find the position by adding frequencies: for this frequency distribution, 23.5th position is 9
Median for this frequency distribution is 9.
<u>Mode</u> is the number or value associated with the highest frequency.
In this frequency distribution, 2 and 9 points happen 10 times. So, mode is 2 and 9.
Mode for this distribution is 2 and 9.
Answer:
Point B is located at point (2, 4)
Step-by-step explanation:
Since point M is at the center, you find the distance from point A and add that to the other side.
| -1 - 0.5 | = | -1.5 | = 1.5
| -9 - -2.5 | = | -6.5 | = 6.5
Now we can add that to point M to find point B
0.5 + 1.5 = 2
-2.5 + 6.5 = 4
Point B should be at (2, 4)
