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: 0.075
Step-by-step explanation: when you are working with percentages to decimals you want to move the decimal two places to the left. If you are working with decimals and you want to make it a percentage you would move the decimal two places to the right.
Answer:
Parallelogram
Step-by-step explanation:
I have plotted the given coordinates in a graph, so that you can see clearly what shape it is. However, in the exam you will not able to do that. Therefore, you would have to draw a sketch of the y- and x- axis, and then lable the coordinates quickly. Some practice on this would give you that skill.
Hope this helps. ☺
monthly payment according to interest rate will be $130.45
What is interest rate?
An interest rate is that the quantity of interest due per amount, as a proportion of the quantity lent, deposited, or borrowed. the full interest on an quantity Lententide or borrowed depends on the corpus, the charge per unit, the change of integrity frequency, and also the length of your time over that it's Lententide, deposited, or borrowed.
Main body:
The amount to be repaid in 48 monthly payments = Cost of the automobile - Down Payment ($1240)
A = P(A/P,i,n)
P = 6200-1240 = $4960
n = 48
i = 1% per month
Hence A= 4.960( A/P, 1%, 48)
A = 4960 (0.0263)
A = $130.45
