Answer:
1. Randomly divide the available set of observations into two
parts, a training set and a validation set or hold-out set.
2. Fit the model on the training set.
3. Use the resulting fitted model to predict the responses for the
observations in the validation set.
4. The resulting validation set error rate is typically assessed using
the MSE in the case of a quantitative response. This provides
an estimate of the test error rate.
Answer:
(-1, 5)
Step-by-step explanation:
Rearrange the the first equation to have y on one side and all other values on the other side
y = 1 - 4x
since both of the equations are equal to y, set them equal to each other an solve for x.
1 - 4 x = x + 6
-5 = 5 x
x = -1
plug this back into the second equation to get y = 5
Answer:
The blank would be 64 and the answer would be 16
Step-by-step explanation:
Because we are looking for 25% of something, we simply multiply .25 by whatever that number is. So we start with
.25 * ________
And then we put the number in
.25 * 64 = 16
Answer:
Step-by-step explanation:
-3(2x+5)=-15
-6x-15= -15
-6x=0
