Using it's formula, it is found that Val's margin of error is of 9.8 pounds.
<h3>Margin of error:</h3>
The margin of error is given by the following equation:
In which:
- s is the standard deviation.
In this problem:
- The standard deviation is of 50, hence
.
- Val weighed 100 cows, hence
.
Then:
Val's margin of error is of 9.8 pounds.

The area of the flower bed is 77 square feet
<h3>How to determine the area?</h3>
The given parameters are:
- Shape = Triangle
- Perpendicular sides = 14 feet and 11 feet
The area of the flower bed is calculated as:
Area = 0.5 * Product of perpendicular sides
So, we have:
Area = 0.5 * 14 * 11
Evaluate
Area = 77
Hence, the area of the flower bed is 77 square feet

The 2-point form of the equation of a line can be written as ...
... y = (y2-y1)/(x2-x1)·(x -x1) +y1
For your points, this is ...
... y = (1-5)/(3-6)·(x -6) +5
... y = (4/3)(x -6) +5
It can also be written as
... y -5 = (4/3)(x -6)
