Actual weight (ounces) Predicted weight (ounces)21
To Find : the sum of residuals
Actual - Predicted=Residuals
So, the residuals are 0,3,1,2, -1,2
Thus the sum of all residuals = 0+3+1+2-1+2 = 7
Hence the sum of residuals is 7
The formula to find the residual is given by:-
Let the actual weights be and the predicted weight be , then
The sum of the residual=
Hence, the sum of the residuals is 7.
The equation that is used to calculate the weight of an object on a planet is A. W=mg
In this case to find the weight of an object you must use the formula.
W = mg
The answer is 7
To start off, we make subtract the actual weight to the predicted weight. 9-9 ; 15-12 ; 16-15 ; 20-18 ; 20-21 ; 26-24 . After subtracting each column above we get 0,3,1,2,-1,2. We have to now add so that would leave us a 7.
Hope this helps, I know this is right I took the test! Have a nice day!
The equation used to calculate the weight of an object on a plant is F = ma. "F" is the force measures in Newtons, "m" is the mass measures in grams and "a" is the acceleration that accur due to gravity.
W = mg is used to calculate the weight of an object on a planet.
W = mg
Sorry if i get you right, we calculate weight by simply multiplying mass by the gravity on the surface of the planet.
Weight = Mass x Surface Gravity
W = m × g
So, if you know your weight on Earth
and the surface gravity on Earth, you
can calculate your mass. You can then
calculate your weight on any other
planet by using the surface gravity of
that planet in the same equation.
If you know the mass on like g = 9.81 m/s² for planet earth.
the weight of an object on a planet is given by the law:
m is the mass of the object
g is the value of the gravitational acceleration on the planet
While the mass of the object, m, depends only on the properties of the object (so, it is the same on every planet), the weight W, depends on the value of g, which is different from planet to planet, therefore the weight of an object changes if we move it to another planet.
weight is equal to the mass of the object multiplied by the force of gravity which is written as a small g.
The formula would be w = mg
