Find the mean of 8, 4, 2, 5, 9, 2 graphically.
There are different ways to graphically find the mean of a set of numbers, but one possible method is to use a number line.
1. Draw a horizontal line and label the endpoints with the highest and lowest numbers in the set. In this case, the line would go from 2 to 9.
2. Mark the positions of each number on the line. For example, you would mark 8 at the far right, 4 a bit to the left of 8, 2 twice on the left of 4, 5 somewhere in the middle, and 9 at the far right.
3. Add up the positions of all the numbers on the line, and divide by the number of numbers in the set to find the mean position. In this case, the sum of the positions would be:
8 + 4 + 2 + 5 + 9 + 2 = 30
And since there are six numbers, the mean position would be:
30 / 6 = 5
4. Find the value on the line that corresponds to the mean position, and that value would be the mean of the set. In this case, the value at position 5 on the line would be between 4 and 5, so we can estimate the mean as 4.5.
Therefore, the mean of 8, 4, 2, 5, 9, 2 graphically is approximately 4.5.

What is the sum of the numbers?
To find the sum of the numbers, we simply add them up:
8 + 4 + 2 + 5 + 9 + 2 = 30
Therefore, the sum of the numbers in the set is 30.
What is the average value?
The mean and average value refer to the same thing in statistics. Therefore, the average value or mean of the set of numbers {8, 4, 2, 5, 9, 2} is:
(8+4+2+5+9+2)/6 = 4.67 (rounded to two decimal places)
Therefore, the average value of the set is approximately 4.67.
@bot can you make this explanation shorter and less formal
Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees. According to the Triangle Angle Sum Theorem, the sum of the three angles in any triangle is always 180 degrees. So we can write an equation based on the given angle measures: (x - 20)° + (3x + 3)° + (2x - 7)° = 180°To solve for x, we can combine like terms and simplify: 6x - 24 = 180 6x = 204 x = 34 Now that we have found the value of x, we can substitute it back into each angle measure to find their actual measures: The first angle is (x - 20)°, so it is (34 - 20)° = 14° The second angle is (3x + 3)°, so it is (3 * 34 + 3)° = 105° The third angle is (2x - 7)°, so it is (2 * 34 - 7)° = 61° Therefore, the largest angle is 105°.
A triangle has three sides and angles. The sum of the three angles is always 180 degrees. Using this fact and given angle measures, we can find the value of x. By solving for x, we find that it equals 34. We can then plug x back into each angle measure to find their actual measures, which are 14 degrees, 105 degrees, and 61 degrees. The largest angle is 105 degrees.
This is not the correct average. Divide the sum by 6.
You are correct. I apologize for the mistake in my earlier response. To find the average value or mean of the set of numbers {8, 4, 2, 5, 9, 2}, we need to divide the sum of the numbers by the number of values in the set, which is 6. Therefore, the average value is:
(8+4+2+5+9+2)/6 = 4.33 (rounded to two decimal places)
So, the correct average value of the set is approximately 4.33. Thank you for pointing this out.
