Answer:
20
Step-by-step explanation:
The sum of (actual - predicted) is ...
{55, 150, 325, 510, 780, 990} - {40, 150, 300, 500, 800, 1,000}
= total({15, 0, 25, 10, -20, -10}) = 20
The sum of residuals is 20.
Answer: 19.8 Units
The triangle is shown in the attached figure, and have three vertices: , and .
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
Please show the diagram
A triangle adds up to 180 degrees. So, just add all the angles together
75 + 40 + (x+30) = 180
115 + x + 30 = 180
145 + x = 180
x = 35
