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:
The discriminant of this quadratic equation is less than zero.
This means the quadratic equation will have no real solution(s) and two complex solution(s).
Step-by-step explanation:
The discriminant is found using the formula b^2 - 4ac.
Therefore, the discriminant is (3)^2 - 4(2)(5), which yields -31.
Since the discriminant is negative, there are no real solutions.
Answer:
Y over X axis pretty sure
So your answer is 2 over -1 if 2 is the Y and 7 over -1 if 7 is the Y
