Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.

Explanation:
Answer: Solution: Algorithm:
Step 1: Start.
Step 2: Create a stack Step
3: Push an initial stack variable, it will represent that, stack is empty.
Step 4: Get input
If +1 then push "+1"
Else if -1 then pop
Step 5: Repeat until all input finish or Stop if empty stack variable popped. Step 6: Stop.
It is a pushdown automata problem.
It can be also represented as:
X =1+1* —1* 1No(+1)>= No(-1)}
Answer:
Henry can replace the laptop system board.
Henry can use the laptop only when it’s connected to the power using the AC adapter.
Explanation:
The question presents a scenario where the laptop is not charging.
As the question specifies, working battery from another laptop is not working as well in his laptop. So most probably, the fault is in his laptop and he would have to get it fixed. In the time being, he can still use his laptop only when its connected to power using the AC adapter.
3 would be self management
