Question

using the fact that the black triangle represents the mean and/or the understanding of what a deviation is, explain why this balancing beam would stay balanced went to Blue circles are removed. Be thorough with your explanation and use Multiple sources of evidence​

Answer 1

Answer: the left side is balanced with the right side

Explanation:

Left side:

1 barrel (located at 2) is 1 unit from the fulcrum (triangle) → 1(1) = 1

2 barrels (located at 1) are 2 units from the fulcrum (triangle) → 2(2) = 4

1 barrel (located at 0) is 3 units from the fulcrum (triangle) → 1(3) = 3

Total = 8

Right side:

1 barrel (located at 6) is 3 units from the fulcrum (triangle) → 1(3) = 3

1 barrel (located at 8) is 5 units from the fulcrum (triangle) → 1(5) = 5

Total = 8

The distribution of the weight on the left side equals the distribution of weight on the right side so the beam is balanced.
