Answer:
9
Step-by-step explanation:
The mean squared error (MSE)of a set of observations can be calculated using the formula :
(1/n)Σ(Actual values - predicted values)^2
Where n = number of observations
Steps :
Error values of each observation (difference between actual and predicted values) is squared.
Step 2:
The squared values are summed
Step 3:
The summation is the divided by the number of observations
The difference between the actual and predicted values is known as the ERROR.
(1/n)Σ(ERROR)^2
n = 3
Error = +3, +3, - 3
MSE = (1/3)Σ[(3)^2 + (3)^2 + (-3)^2]
MSE = (1/3) × [9 + 9 + 9]
MSE = (1/3) × 27
MSE = 9
Answer:
height = 3.18
Step-by-step explanation:
volume = π * r^2 * h/3
volume = 120
r = 12/2 = 6
Answer:
~24.4%
Step-by-step explanation:
A circle is 360 degrees, we all know this.
The angle representing Techno is 28° While Country has a 60°. Combine this and we get 88° of people total chose country or techno. 88° divided by 360° gives us 0.2444444... With percentages, we move the decimal two places to the right, giving us:
~24.4%
Answer: The answer is 1296
Answer:
y = 26
Step-by-step explanation:
Given y varies directly as x and inversely as the square of z then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 52, x = 16, z = 2
k = = = 13
y = ← equation of variation
When x = 18 and z = 3, then
y = = 26
