Answer:
21
Step-by-step explanation:
Remember that the centroid splits the 3 medians of a triangle into a ratio of 1:2
Since TS < TN, TS = 42/2 = 21
You can add a lot of numbers (or so I think). One number I think you can add is 31.
Answer: A
Step-by-step explanation:
See how many times the coordinates are plot
I don't know the area of a parallelogram off the top of my head but you can use the area of the rectangle and the area of the triangle and add those. The area of the triangle is 1/2*base*height and use the pythagorean theorem to find the base. 3² + b² = 5²; 9 + b² = 25; b² = 16; b = 4. The area of the triangle is 1/2*4*3 or 6 in. Since there are two of them, the total area of the triangles are 12 in. The area of the rectangle is length*width or (12 - 4) * 3 which is 8 * 3 or 24in. Add these areas together to get 36in total
Solution: We are given below data:
Now to find the mean deviation, we use the below formula:
Where:
represents the summation
X, represents the observation.
represents the mean
N represents the number of observation.
Therefore, the mean deviation is:
= 4
